CEOMESSAGE

Dear Stakeholders of POSCO ENERGY,

This year celebrates POSCO ENERGY's 50th anniversary of founda-tion, and it is preparing big changes for the next 50 years to come. Being the first in Korea to successfully engage in Independent Power Project by launching the construction of the Incheon Power Plant in 1969, POSCO ENERGY has contributed to Korea’s rapid in-dustrialization in a short period of time. As Korea's first and largest independent power producer with continued growth over the last 50 years, POSCO ENERGY, has overcome the recent years of difficulty and will make changes for a new leap forward.

The ‘POSCO ENERGY Corporate Citizenship Report 2018’ includes the achievements of business re-structuring in 2018 to turn crisis into opportunity as well as the plans to step forward into 2019 while celebrating the 50th anniversary.

In 2018, changes in the energy paradigm including the nuclear-power policy, suspension of aged coal power, and expansion of new and renewable energy were accelerated. Given these changes, POSCO ENERGY is seeking various strategic directions to advance into a ‘Global Eco-friendly Energy Company focused on Gas & Power'. Based on the current global market size and future growth potential of gas business, in the first-half of 2018, POSCO ENERGY has decided to import gas directly which will enhance synergy with LNG power plant operation. Also, in an effort to expand into relevant industries POSCO ENERGY has established a LNG trading firm in Singapore and prepared to acquire the Gwangyang LNG terminal. In 2019, POSCO ENERGY plans to reorganize the energy business model through forming of a new gas infrastructure through early stabilization, construction of new tanks, and expansion of the Gwangyang LNG terminal operations. POSCO ENERGY will secure cost competitiveness through direct operation of Gwangyang LNG terminal, and grow into a globally recognized comprehensive energy pro-vider through terminal lease, as well as expanding POSCO ENERGY's business into ship bunkering and overseas liquefaction terminal in the long term. On top of that, POSCO ENERGY pledges to continue fulfilling the management philosophy of 'corporate citizenship: Building a Better Futuer Together'. In January 2019, POSCO ENERGY's "Energy Dream" project was introduced on the UN SDGs(Sustainable Development Goals) website. POSCO ENERGY has contributed to resolving social problems by reducing the cost of energy for vulnerable groups since 2012, creating warmer and brighter residential environments.

A corporate’s sustainability should start from the employees and expand to partners, local communities and the country. POSCO ENERGY is committed to creating a healthy work/life balance, a family-friendly working environment that provides confidence and loyalty for the company, and to providing a variety of benefits to its partners. In addition, POSCO ENERGY strives to provide support by strengthening sport activities for the local community through the operation of a table tennis volunteer group.

POSCO ENERGY begins to take on a new challenge towards building a corporate history of 100 years. I ask for your continuous interest and support in accomplishing the group's manage-ment vision 'With POSCO' for all of the major stakeholders such as Business, Society, and People. Thank you.

Message from the Executives

Risk management through thorough analysis and creation of new business opportunities

In May last year, after POSCO ENERGY’s fuel purchase contract with KOGAS has expired, it signed a contract for

direct LNG import for use in its Incheon Combined Cycle Power Plant. Since the end of 2018, POSCO ENERGY has been directly importing LNG, and has been operating Unit 3 in the Incheon Power Plant using mid-term contract

volumes and SPOT volumes, improving the company’s profit and contributing to the electricity market on a na-tional level. In the process of importing LNG directly, POSCO ENERGY thoroughly analyzed risks and established

strategies to overcome those risks. To overcome the risk of shortage and surplus of LNG, POSCO ENERGY re-viewed businesses such as those related to the terminal which can create new opportunities. POSCO ENERGY will continue to increase the company’s sustainability by identifying risk factors regarding new changes and cre-ating new opportunity factors.

Shin Changdong, Senior Executive Vice President, Head of Business Development Division

Promoting an integrated safety management system by setting the safety of employees and partners as the top priority

The safety and health of all executives and employees are issues that should not only be guaranteed by law, but should be prioritized in order to become a sustainable business and corporate citizen. POSCO ENERGY focus-es on the safety of not only its executives and employees at workplaces, but also that of the local communities and partners. This year, POSCO ENERGY included the 'Zero Accident' goal to its management indicator to build a more responsible and integrated company-wide safety management team, whereas in the past safety was managed by each worksite. In particular, POSCO ENERGY plans to continuously strengthen its safety and health management system through three key managerial improvements: ‘expanding the operation of safety system for co-prosperity with partners', ‘strengthening employee responsibility for safety activities', and ‘conducting diagno-sis for compliance of Occupational Safety and Health Act amendment'.

Jeong Kiseop, Senior Executive Vice President, Head of Corporate Planning Division

Smartization of power plants to enable high efficiency, zero outage, and zero accident operation

Power plants are extremely sensitive facilities that collect and store massive amounts of data every second from tens of thousands of sensors, and operators manage facilities by responding to emergency situations based on application of their experiences. Based on big data analysis technology and the experiences of operators, smart power plants, which proactively identify factors of outage and efficiency improvements and take actions, have been promoted to realize ‘high efficiency, zero outage, zero accident power plants'. In this process, POSCO ENERGY established its unique smart power plants that combine external softwares with internal engineers' experiences, and based on the success of the implementation of Incheon Units 7 to 9, the establishments have expanded to Units 5 and 6 of the Incheon power plant as well as Gwangyang/Pohang Off-Gas power plants.

The Independent LNG Combined Cycle Power Plant, which was considered a stable business, experienced a lower rate of operation resulting from the base load power generation expansion of nuclear power and coal-fired thermal power. Due to the changing environment caused by LNG direct im-port of competitors, POSCO ENERGY faced an unprecedent-ed crisis. To turn crisis into opportunity, POSCO ENERGY re-alized risk management is a crucial factor for sustainability and established integrated risk management to respond swiftly to the internal and external risks. The company is now working on a system to minimize risk, starting with defining the role and responsibility of the ERM Group and the specialized departments(relevant division) by risk type.

Integrated Risk Management SystemThe risks of a company can be divided into external risks and internal risks. External factors include changes in ex-ternal management conditions and external corporate im-age, whereas internal factors include finance, human re-sources, information security, and safety. The ERM group looks at all risk factors, excluding risk types that are clear and dealt with by the relevant departments. It looks main-ly into investment management, which is new investment verification and monitoring of investments in progress. Over the past several years, POSCO ENERGY has focused on internal risk management for business normalization, but now the company plans to expand its roles to moni-toring external risks and establishing management re-sponse systems jointly with the risk-specific department.

Financial Risk ManagementPOSCO ENERGY operates an efficient risk management system that encompasses all finance areas including ac-counting, taxation, and funding. In particular, the company minimizes volatilities of exchange and interest rates with hedge trading of foreign currency loans through derivatives contract of Swap, Forward, and MAR(market average rate).

Investment Risk ManagementIn the power generation business, there are two types of investments: current investment, which includes mainte-nance, and new business investment. Maintenance is di-rectly related to the operation rate of power plants, that is, profit. As a result, a thorough review of investment sched-ules, budgets, and effect is necessary. Current investment focuses on the company's internal capability while new business investment focuses on the company's growth. However, Renewable Portfolio Standard obligations and the coal phase-out generation trend is causing subdued growth with factors such as the saturated domestic independent LNG power generation market. In the past, the focus was mainly on quantitative growth by increasing generation ca-pacity and the number of operating projects but now is the time to shift to qualitative growth. While enhancing the val-ue of the LNG combined cycle power generation, POSCO ENERGY will create a business portfolio centering on new businesses that strategically respond to the changes of the external environment and promote internal stability. The ERM group identifies risks regarding new businesses and monitors the process while managing mutual investment companies by conducting Gate Reviews.

toring of security activities by security managers have been strengthened, and the restricted area set according to the company’s defense plan, restricting the entrance of any per-son unrelated to the joint preparation during the integrated defense plan of the military and police to prevent physical or human damage. Fifth, improvement factors are identified and managed by establishing a spot check system of inte-grated defense factors and conducting regular visits from a government organization, local government and military unit.

Information ProtectionPOSCO ENERGY's information protection activities are op-erated based on the Information Security Management System(ISMS) led by the Ministry of Science and ICT. After participating in the voluntary certification in 2015, POSCO ENERGY renewed the certification for three years and es-tablished a systemized management standard. Based on this, POSCO ENERGY is putting effort into compliance with relevant laws and regulations and operations of Information Security Management System. For information protection policy, POSCO ENERGY is actively reflecting the charac-teristics of a power generation business and implement-ing corporate information protection through regulations and guidelines. For Critical Assets and IT Security, POSCO ENERGY is protecting information assets through manage-ment and risk assessment and action. As of March 2019, POSCO ENERGY was able to safely protect company infor-mation assets without any incidents. Security conscious-ness of employees and partners is being strengthened and an information protection campaign is launched more than twice a month to increase security awareness. POSCO EN-ERGY is sharing key points regarding information protec-tion through in-house bulletin boards and when issues of malicious email inflow arise POSCO ENERGY immediately informs all employees to prevent information leakage and infectious incidents. With the PI3.0 Project(Nov. 2012 - Jul. 2014), POSCO ENERGY implemented an optimized enter-prise integration system to replace the division focused system. POSCO ENERGY is also operating an integrated ERP system of sales, production, and finance through a systematic management of enterprise integration system. IT operations such as change in regulations and systems, authority change from job rotation, and system access, are managed throughout the company to guarantee the highest user satisfaction and security. In addition, with the operation of Service Level Agreement, POSCO ENERGY is striving to enhance service quality and user satisfaction.

Non-Financial Risk ManagementPOSCO ENERGY's 37 corporate citizen communicators define risk factors that needs management each year and allows management that suits the rapidly changing exter-nal and internal business factors. There are 117 risk factors derived from benchmarking 29 major power producers and excellent risk management companies. Each communica-tor categorizes the risk in three categories: Critical, Mod-erate, and Minor, based on financial impact and probability. Risks such as currency, capital, credit rating, new business investment and affiliates while non-financial risks such as ethics, safety of business sites, and environmental issues are managed proactively.

Emergency Response SystemThe Incheon power plant is designated as a national securi-ty facility and a major national facility to supply stable pow-er to the Metropolitan Area. The plant built an emergency response system to counter activities that fundamentally restrict the situations that have serious impact on nation-al security and people's lives. In case of an emergency, the plant effectively responds to the infiltration, provocation, and threat of suspicious people, averting damage to per-sonnel, facilities and equipment and is working to establish a full-fledged work defense system. First, to ensure com-plete workplace protection, POSCO ENERGY has signed agreements with the heads and chiefs of military units, police stations, fire stations, local governments, and major national facilities, to cooperate in an integrated defense op-eration. Internally, POSCO ENERGY is prioritizing the estab-lishment and execution of a workplace protection measures and protection support plans as well as the operation, cul-tivation, and support for workplace reserve forces. Second, the Emergency Preparedness Officer and the Reserve Unit Commander collaborate with the Workplace Reserve, Civil Defense Units, and the Special Security Guards, and have created a comprehensive situation room where a unified defense system is built to combine portable obstructions such as fixed barriers on barbed wire, barricades, wire fenc-es, and scientific surveillance equipment. Third, to create preparations for an integrated defense system, trainings on identifying suspicious intruders and reporting are conduct-ed regularly along with education and promotional activities regarding infiltration strategy. Also, POSCO ENERGY pro-vides generation facility security and protection training and response method training to employees for quick response in emergency situations. Fourth, the guidance and moni-

In 2011, POSCO ENERGY set a strategic goal to become a beloved company that harmonizes economic, social and en-vironmental performance pursuing its will for sustainable management in the TOP(Tomorrow of POSCO ENERGY) Council with the CEO as the chairman. Since that year, the company established a new department and has been con-ducting various activities to internalize sustainable manage-ment through organic cooperation with the departments by sector. In 2018, POSCO group announced new management philosophy, "Corporate Citizenship: Building a Better Future Together", and POSCO ENERGY is preparing for change by re-assessing and developing its corporate citizenship activities.

The UN Sustainability Development Goals(SDGs) are the 17 goals the U.N. has set for addressing social problems and the sustainable development of our planet. POSCO ENERGY supports the UN and the UN SDGs international community implementations and pledges to pay attention and address the universal problems of mankind. In particular, as an energy company, POSCO ENERGY will find opportunities to contribute to society by focusing on three goals: Affordable and Clean Energy(#7), Industry Innovation and Infrastructure #9), and Sustainable Cities and Communities(#11). In January 2019, POSCO ENERGY's representative social contribution project, 'Energy Dream', having been implemented since 2012, was introduced on the UN SDGs website.

UN SDGs

• Plant Smartization with average outage rates

0.13%(1.08% in 2016)

• New and renewable energy generation capacity

87.2MW(2016, 38.5MW → 2017, 56.5MW)

• Promotion of LNG direct import business and rationalization of power generation cost

• Since the start of business in 2012, 391 households and 53 facilities have been supported with energy efficiency

• Cumulative energy savings of about KRW 125.7 million, saving KRW 2.8 million on average per year

While pursuing economic development, a company should also create social values as a member of the society and grow together with the society. Along with the traditional values of management, such as increased financial perfor-mance and profit, social and environmental responsibilities are also important for a company. POSCO ENERGY plans to focus on creating social values as a corporate citizen to build a better future together. As the importance of social responsibility and sustainabil-ity intensify, companies are starting to focus on their sus-tainability and are systematically managing it. This is call-ing forth a greater effort to accurately recognize the social values that a company is creating by measuring sustain-ability performance. POSCO ENERGY also pursued an in-depth approach regarding the economic, social and envi-ronmental activities of the company with its publication of the 2018 corporate citizenship report. POSCO ENERGY will strive to manage and measure social effects from a broad-er perspective by expanding its social value management indicators. As of 2018, the company’s social value totals KRW 112.37 billion based on the K-IRFS standard, in which indirect economic contribution including interest paid and corporate tax, social contribution, sustainable management including environmental effect, and corporate citizenship performance are reflected for measurement.

Creating Social Value

Affordable and Clean Energy POSCO ENERGY pursues a universal approach to modern energy through the advance-ment of Combined Cycle Power Generation, the company's unique business, and strive to secure competitiveness for cost and efficiency in power production and facility by in-creasing the operational efficiency. Furthermore, POSCO ENERGY is responding to the government's ‘New and re-newable energy 3020 policy' by continuously increasing the portion of new and renewable energy business, such as wind & photovoltaic power business.

Industry, Innovation and Infrastructure UNIDO emphasiz-es in the 'Inclusive and sustainable industrial development' report that the use of clean energy and increasing energy efficiency are critical factors to sustainable growth. POSCO ENERGY strives to improve the business sustainability of power generation through the introduction of clean technol-ogy and improvement of utilization efficiency.

Sustainable Cities and Communities Under the social contribution slogan 'Energy for a better world', the com-pany is implementing various businesses. POSCO ENERGY strives for environmental improvement and residential pub-lic service provision through the 'Energy Dream' project for energy-vulnerable groups, which involves improvements in energy efficiency, electrical equipment inspection, and lo-cal government welfare facilities support with photovoltaic power facilities.

POSCO ENERGY discloses sustainability activities and achievements in accordance with the global GRI standards to the stakeholders. Every year, reporting topics are selected through a materiality analysis and the content is created. In 2019, POSCO ENERGY selected the top 10 material issues focusing on business impact and stakeholders’ interest based on internal and external environment analyses and stakeholder surveys. The materiality analysis for this report was conducted in April, 2019.

Materiality Analysis

5 Selection of Reporting Issues Derived from the analysis, the material issues and reporting scope that should be reported primarily on the corporate citizenship report are as follows:

Implications from Materiality Analysis• International Initiative Compliance: Some issues that consider POSCO ENERGY's

industry characteristics and the relevance to national policy may deviate from the global initiative economy indicators, but this is due to industry characteristics.

• Same Industry Benchmark: Companies of the same industry as POSCO ENERGY try to add various issues in their reports; in particular, the majority of the 25 benchmark companies include air pollution related issues from the environmental aspect and HR issues from the social aspect.

• Media Research: According to the analysis of POSCO ENERGY's media report overview in 2018, reports tend to focus on management performance(283 cases, 20.43%) and social contribution(289 cases, 20.87%) while the media’s interest in the environment was relatively low(60 cases out of a total of 1,385, 4.33%).

• Stakeholders Survey: According to the POSCO ENERGY's stakeholders survey in 2018, ethical management, creating economic value, air pollutant control and strengthening financial soundness were analyzed as issues of high interest of stakeholders. In particular, ethical management was selected to be of highest importance.

4 Verification The material issues from the materiality matrix are reported to management(executives) to confirm the va-lidity. POSCO ENERGY identified 10 issues with high stakeholder interest and high business impact. They, along with the derivation process, were reported during the management interview and were confirmed as the final material issues.

3 Composition of Materiality Matrix To derive material issues, a matrix was formed based on business impact and stakeholders’ interest.

The stakeholders’ interest was measured through ①Media Research, and ②Stakeholder Surveys

Interview with Stakeholders

Professor Shin Hyundon, Inha University

Q1 | With the vision to grow into a 'Global Eco-Friendly Energy Company focused on Gas & Power', POSCO ENER-GY is expanding the business portfolio to new industries. Please share your opinion on the way POSCO ENERGY's management strategy is contributing to the national power policy and energy mix as well as your thoughts on the fu-ture direction POSCO ENERGY should aim for.

A1 | By reducing fossil fuels and increasing new and renewable energy, I believe POSCO ENERGY is moving in the right direction towards a cleaner and safer energy source, which is necessary for the well-being of the citizens and industries. Also, I believe that increasing the proportion of gas in power generation while improv-ing efficiency and eco-friendliness is a valid mid- to long-term strategy. As for my thoughts on POSCO ENERGY's future strategical direction, I suggest an active pur-suit of securing low-carbon energy sources after a thorough evaluation of the gov-ernment's energy policies and their applicability and enforceability considering our situation, rather than simply complying with the government’s direction of energy

mix policy. From a long-term perspective, it could be advantageous for the company to go beyond the direct importation of LNG and take steps to secure energy sources directly.

Q2 | What commitments do you think POSCO ENERGY should make in order to cre-ate social values and pursue its management philosophy of 'Corporate Citizenship: Building a Better Future Together' towards establishing a sustainable corporate history of 100 years?

A2 | POSCO ENERGY should redirect passive policies that avoid responsibility to establish a corporate culture of pursuing mutual profit and social values. To ac-complish this, a practical and transparent operation of the board is crucial. More-over, it is pivotal that POSCO ENERGY establish a sustainable management system that allows it to pursue responsible management in its mid-to long-term vision, which will enhance corporate value. I believe that POSCO ENERGY can grow into a more sustainable company by reshaping its top-down corporate culture to promote more effective communication. Furthermore, taking part in volunteering for the lo-cal communities and actively cultivating future talent will allow POSCO ENERGY to become a more sustainable company.

Overview Commitment Preparing for 100 years Corporate Citizenship Activities Activities and Performance Appendix 3130 CORPORATE CITIZENSHIP REPORT 2018

Financial StatusIn 2018, the global economy maintained a stable growth rate, but due to expectations on prolonged trade disputes between the U.S. and China and increased U.S. interest rates resulting in economic unrest in emerging economies, there is a growing concern of the weakening the global economy. Although private consumption increased, South Korea recorded a 2.7 % growth due to reduced investment in construction and facilities. Further-more, performance of the IPP Sector in the electricity market showed significant contrasts among companies and although coal power plants and direct LNG import power plants with high cost competitiveness showed tangible improvements, IPPs that rely on KOGAS LNG suffered from an increased reverse margin loss due to a misstatement in the fuel cost settlement structure. Moreover, profitability per unit decreased compared to the same peri-od last year. POSCO ENERGY's revenue of 2018 recorded KRW 188.2 billion, which is a 26.1 billion increase from 2017 but due to the environmental change in the fuel cell industry, loss on valuation of inventories pulled down operating profits to KRW 47.1 billion in 2018, a decrease of 119.1 billion from 2017. According to the consolidated financial statements, the total assets are KRW 4,155.2 billion as of 2018, which is a decrease compared to that of 2017. The total liabilities are KRW 2,803.2 billion, and debt-to-equity ratio is 207%, a 17%p increase compared to last year. After the completion of the large-scale investment con-struction of Incheon power plants unit 7, 8, and 9, POSCO ENERGY is focusing on current investments and strengthening financial soundness.

Credit RatingIn 2018, credit rating companies graded POSCO ENERGY's credit rating as AA-(Stable), which is relatively higher than the average IPP in Korea. The rationale behind the grading took into consideration the diversified power generators as the largest IPP in Korea, sta-ble management structure based on Power Purchase Agreement(PPA) and Cost-Based Pool(CBP), improved cost competitiveness from direct import for unit 3 which will offset the downturn of lower usage rate due to oversupply of the electricity market, stable profit structure, and trend of improvement in financial soundness.

Transparent DisclosurePOSCO ENERGY is fulfilling the duty of disclosure activities related to the major manage-ment status in accordance with ‘the Act on External Audit of Stock Companies’ and ‘the Capital Markets Act and the Fair Trade Act’. POSCO ENERGY communicates with stake-holders such as investors through Data Analysis, Retrieval, and Transfer System(DART) of the Financial Supervisory Service(FSS). In 2018, POSCO ENERGY made a total of 18 disclo-sures.

Financial Soundness

Feasibility of Selecting Material IssuesA company's financial soundness is an indicator that measures its financial stability. It en-hances the attractiveness of investment for the external investors and is an important factor in determining a company's trust and reputation. Thus, a company should put various efforts into maintaining its financial soundness.

Management ApproachPOSCO ENERGY is focusing on increasing the liquidity ratio and lowering the debt ratio to improve financial soundness and is maintaining a stable credit rating. In addition, POSCO ENERGY is pursuing transparency and faithfully disclosing its management performance to investors and stakeholders.

Feasibility of Selecting Material IssuesThe world is facing environmental challenges from fine dust, greenhouse gases, abnormal climate and natural disasters. A company should promote eco-friendly management ac-tivities to prevent risks from environmental issues and work towards sustainable manage-ment. This is one of the most important corporate social responsibilities.

Management ApproachPOSCO ENERGY identifies various possible environmental hazards in business sites in advance and seeks methods to alleviate their negative effects. The company continuously pursues environmental management activities such as establishing an environmental man-agement system, optimizing the environmental management process, and implementing environmental certifications based on ISO 14001. In addition, POSCO ENERGY is striving to create an eco-friendly environment by saving resources and promoting eco-friendly products.

02Environmental Policies and RegulationsIn accordance with the Framework Act on Low Carbon, Green Growth and the Act on the Allocation and Trading of Greenhouse Gas Emissions, power generation companies are subject to release greenhouse gas emissions within their allowances. Any leftover greenhouse gas emission allowances can be sold or purchased in the market with other companies. POSCO ENERGY responds to climate change according to the national goal of reducing greenhouse gas emissions by 2030. The company takes a systematic approach to the Emissions Trading Scheme including policy responses, emissions management, and trading emission allowances. The LNG combined cycle power plant, which POSCO ENERGY operates, is a high efficiency generation facility that can generate electricity by utilizing low amounts of energy. It recovers the heat from gas turbines and operates steam turbines. In 2018, the amount of energy consumption was 112,805 TJ, greenhouse gas emissions were 11,697,326 tCO2, the greenhouse gas emission base unit was at 0.69 CO2/MWh, and direct emissions from fuel combustion accounts for 99.6 %. In 2018, POSCO ENERGY did not re-ceive any sanctions due to violations of environmental laws and regulations.

Implementation StrategiesAs the allowance of the energy transition sector is 228,061,000 KAU, POSCO ENERGY needs to strategically manage the GHG emission. Therefore, POSCO ENERGY is improv-ing efficiency in power generation facilities, establishing a greenhouse gas inventory that lists emissions by source, and managing carbon emissions through the Emissions Trading Scheme.

Environmental Management SystemPOSCO ENERGY has established an environmental management strategy that aligns with the corporate vision and mission while implementing detailed application strategies such as the green system, green operation, green business and green communication. At each business site, there are organizations that focus on environmental management, and the environmental policy group at the headquarters is in charge of company-wide environ-mental management. The group responds to amendments of environmental laws and regulations, modifies and reflects execution plans after evaluating its impacts, discloses the information to stakeholders, and responds to internal and external environmental ex-aminations.

vention facilities in real time. Therefore, POSCO ENERGY is equipped with the system that allows POSCO ENERGY to identify and respond immediately to air pollution indi-ces, such as chemical oxygen demand(COD), suspended solid(SS), and potential of hydrogen(pH) abnormalities. In the case of wastewater treatment, the Incheon power plant reuses less polluted water in the generation process and discharges water pollutants according to its own stan-dard that is significantly lower than that of the legal man-datory standard. Off-Gas combined cycle power plants in Pohang and Gwangyang discharge wastewater by trans-ferring it to the steel mill, which is then treated along with the wastewater produced in the steel mill. No waste water is being produced at the Pohang fuel cell plant.

Waste Control | The waste generated in power plants in-cludes general waste, such as sludge from wastewater, waste synthetic resins, and waste adsorbents, as well as designated wastes including liquid oil waste and solid oil

waste. With the 'Allbaro System' of Korea Environment Corporation(KEC), POSCO ENERGY managesre transpar-ently the entire waste treatment process from generation, storage, transfer to final disposal, and minimizes waste discharge by saving resources and promoting recycling. The waste produced is treated legally from outsourcing agencies. Furthermore, wastepaper and scrap iron are handled by waste discharging companies.

Chemical Substance Control | POSCO ENERGY manages chemical substances used in the demineralized water production process and the air/water quality control pro-cess in compliance with relevant laws and regulations including the Chemicals Control Act, and Occupational Safety and Health Act. POSCO ENERGY focuses on pre-venting chemical accidents by installing over-injection preventive facilities and conducting regular training ses-sions to make sure workers are capable of safely han-dling any possible chemical leakage accidents.

operates the Enterprise Resource Planning(ERP) system to manage greenhouse gas emissions and implement Re-newable Portfolio Standards while providing important in-formation for the management's decision-making process through EIS.

Restructuring the Energy BusinessPOSCO is aiming to strengthen its group-wide LNG mid-stream and downstream business structure as one of the top 100 reform tasks. To maximize synergy between group businesses, POSCO ENERGY will operate Gwangyang LNG terminal and transfer the Gwangyang and Pohang Off-Gas Combined Cycle Power Plants to POSCO. It is expected that POSCO ENERGY will be able to improve efficiency by not only using directly imported LNG for its own power plant, but also and expanding the business to processing and dis-tribution of LNG. On the other hand, POSCO will be able to strengthen the stability of electric power supply to steel mills by integrating Off-Gas combined cycle power plant with existing power generation facilities. In April 2019, the BOD approved the contract for 'Take over of Gwangyang LNG Terminal,' and in early September, POSCO ENERGY will start the LNG Terminal business.The Gwangyang LNG terminal, constructed by POSCO in 2005, was the first private LNG terminal to be constructed in Korea. It has five LNG tanks – four in operation(units 1 to 4) and one currently under construction(unit 5), of which total storage capacity is approximately 730,000 kl. By 2026, with the expansion of unit 6~9 tanks, the total storage capacity will reach 1.53 million kl which will create an additional KRW 100 billion increase in profit. In May 2018, POSCO ENERGY initiated the direct import of LNG for Incheon Combined Cycle Power Plants units 3 and 4. The surplus in the global LNG market has enabled POSCO ENERGY to directly import LNG with a price that is around 70% of the average LNG import price of KOGAS, which contributed in drastically reducing the company's cost. These effects are expected to increase further with LNG busi-ness restructuring. By assuming the LNG terminal, the core asset of LNG business, POSCO ENERGY is now able to hedge the surplus/deficit risks of direct imported LNG while advancing its midstream business – which involves developing LNG terminal into one of Northeast Asia’s largest energy hubs, LNG bunkering and exporting LNG to close distances. Also, Gas to Power business will be pursued along with POSCO Group, which will link overseas IPP business with gas infrastructure business(LNG receiving terminal).

Creating Economic Value

Feasibility of Selecting Material IssuesThe word "Corporate Social Responsibility" implies many things, but the most basic re-quirement for a business is economic responsibility. A company's economic viability direct-ly affects the stakeholders' lives as well as the society and the national economy.

Management ApproachPOSCO ENERGY is directing its effort to the restructuring of the business in order to re-spond to changes in the external management environment and is focusing on promoting development projects such as overseas IPP and construction of clean power plants. POS-CO ENERGY will continue to actively respond to the rapid changes in management environ-ment as a global integrated energy company.

Samcheok Coal-Fired Thermal Power PlantPOSPOWER is constructing a differentiated power plant with the capacity of 1,000MW in Samcheok, Gangwon-do, which will be the first plant in the world to be built on an aban-doned mine. For 30 years, the region was used to mine limestones and produced pollutants such as fine dust and leachate. To curb the environmental challenges, POSPOWER will promote greenery and create an eco-friendly power plant to ensure the prosperity with the local community by increasing the land’s utilization. The Samcheok power plant can create economic benefits from development funds and business participation within the region and is also expected to vitalize the regional economy in Samcheok by utilizing 1,500 workers a day and 2.3 million workers a year during the construction period. Once the con-struction is completed, the plant is expected to create 1,200 direct and indirect employment opportunities. As South Korea is designated by the UN as a water-stressed country and the risk of securing generation water is gradually increasing, POSPOWER will protect local wa-ter resources and secure stable water supply for power generation by proactively establish-ing seawater desalination facilities. Moreover, the power plant will provide a stable produc-tion and supply of electricity through the application of eight new technologies and facilities.

Fuel Cell BusinessSince 2007, POSCO ENERGY has been promoting the fuel cell business, which generates electricity and heat energy through electric chemical reactions of hydrogen and oxygen. Fuel cell plants directly convert chemical energy to electric power without emitting air pol-lutants and have low energy loss. Unlike other new and renewable energy sources like pho-tovoltaic and wind power, fuel cell is an eco-friendly energy source that can stably produce energy without being subjected to weather conditions. The fuel cell plant in Noeul Park in Seoul , has high spatial efficiency which enables normal operation even in the center of the city where price of land is high, and uses dispersed power generation source that has an effect of reducing fine dust in the air. POSCO ENERGY is operating a plant with a production capacity of 50MW in Pohang for technology development, manufacturing, installation and construction to maintenance.

Business Ethics

Feasibility of Selecting Material IssuesThe essential purpose of a company is to maximize profit, but through heightened aware-ness of corporate citizenship, ethical management is increasing both domestically and abroad. POSCO prioritizes ethical management as a core value of corporate activity as well. Regardless of the management performances, losing social trust is highly detrimental to the company. Thus, companies should put in effort for transparency and fair management and recognize the importance of corporate ethics.

Management ApproachPOSCO ENERGY engages in various training sessions and practices regarding ethical man-agement in order to internalize ethical awareness. POSCO ENERGY will continue to work together to establish a transparent fair trade culture by implementing a system of internal checks based on independence, ethics, and reporting channels, and effective prevention measures. Moreover, POSCO ENERGY will continue to engage in practical activities for the improvement of ethical awareness of the stakeholders as well as the practical activities for the establishment of human rights management system.

Understanding the Electricity IndustryAccording to the 8th Basic Plan for long-term power supply and demand announced by the Ministry of Trade, Industry and Energy(MOTIE) in 2017, the amount of electricity consump-tion in 2030 is expected to be 579.9 TWh and the maximum electricity is expected to reach 100.5 GW. With this plan, the government intends to secure economic feasibility to create safe and clean power generation sources while focusing on a stable supply and demand of electricity.

Structure of Electricity Industry | In the current structure of the Korean electricity indus-try, the power generation companies equipped with power generators produce electric-ity, and Korea Electric Power Corporation(KEPCO) sells electricity to regular customers through the power transmission and distribution network. KEPCO purchases electricity either from Korea Power Exchange(KPX) or directly from power generation companies. Power generation companies include 6 subsidiaries of KEPCO and IPPs. Since its first commercial operation as Korea’s only Independent Power Producer in February 1972, POS-CO ENERGY has enhanced the LNG Power Plant to satisfy the electricity stabilization policy of the Korean Government, and as of 2018, it holds about 10% of the power generation fa-cilities in the seoul capital area and supplies balanced power to the region.

Power Exchange System | The System Marginal Price(SMP), which refers to the electricity price in the wholesale electricity market, is decided based on the power generator with the highest variable cost at a selected time. Variable cost is mainly determined by fuel cost, allowing the LNG Power Plant, which has a higher fuel cost than nuclear power or coal, to determine the price. Apart from the electricity market, the Vesting Contract(VC) approved by the government is another way of making a contract between power producers and KEPCO.

Changing Energy PoliciesThere are various laws related to power generation companies such as POSCO ENER-GY: Energy Act, Electric Utility Act, and Act on the Promotion of the Development, Use and Diffusion of new and renewable energy, etc. The government, in accordance with the Framework Act on Low Carbon, Green Growth, will announce an Energy Master Plan every 5 years for 20 years. This plan is a blueprint of the energy industry of Korea and includes management, prospects of domestic and overseas energy supply and demand, a secure-ment of energy sources, plans for improving utility efficiency, and new and renewable en-ergy policies. Announced by the Korean Government in April 2019, the 3rd Energy Master Plan includes policy tasks regarding energy transition and proposes a mid-to long-term vision. The Electric Utility Act sets general regulations with regards to the electricity indus-try covering power generation to sales and includes contents related to permission to elec-tricity projects, regulations of electricity supply and quality, measures of stable electricity supply, and the formation of the electricity market. In accordance with this act, the Korea Power Exchange(KPX) and the Electricity Regulatory Commission(KOREC) are established as organizations to operate the electricity market. The Ministry of Trade, Industry and En-ergy(MOTIE) formulates Basic Plans for long-term power supply and demand every 2 years for a 15-year period based on the Electric Utility Act, and the 8th Basic Plan includes: fore-cast and management of electricity supply and demand; power generation facilities plans; harmony of economic and environmental dispatches of power; plans for expanding dis-

Renewable Portfolio Standards | The Renewable Portfolio Standards(RPS) of Korea enforces power generation busi-nesses with 500MW or higher capacity to supply a certain rate of their total power generation with new and renewable energy. As shown in the table above, the mandatory supply amounts are set for each year, and for this year, 6% of 2018’s total power generation amount must be supplied. There are two ways to supply new and renewable energy: self-produc-tion and outsourcing. POSCO ENERGY fulfilled the amount of mandatory self-supply in 2018 through its own facilities of photovoltaic power generation and fuel cell facilities and effectively responded to the Renewable Portfolio Standards.

Prospects of the Electricity IndustryAccording to the 8th Basic Plan for Electricity Supply and Demand, the capacity ratios of each power source by 2031 are expected to be: 12% of nuclear power; 23% of coal; 27% of LNG; and 34% of new and renewable energy. Fol-lowed by the public concerns on the safety of nuclear pow-er plants, social issues related to high-density fine dust and fulfillment to GHG reduction goals, the importance of new and renewable energy and LNG power generation is expected to grow. In 2018, POSCO ENERGY signed a con-tract for direct LNG import at the Incheon Combined Cycle Power Plant whose fuel purchase contract with KOGAS

expired. The direct import of LNG adopted in early 2019 is expected to improve profitability by reducing power gener-ation costs. POSCO ENERGY will secure additional profit by implementing direct LNG import in other power plants in 2020 as well.

Energy Transition and New IndustryRecently, the Korean government established the Energy Transition Roadmap and announced to promote the future energy industry. Energy transition refers to the restructur-ing of energy consumption from conventional fossil fuels to cleaner fuels that are safer, cleaner and more efficient. The government plans to establish a Big Data Platform and the Internet of Energy(IoE) System throughout the power grid to create new energy services. In addition, the government announced that it will provide continued support to new business in the energy industry for job creation and indus-trial innovation. New Business for Energy Industries refers to a new business area of combining new technologies such as Information and Communications Technology(ICT) in the energy industry. In particular, the electricity industry includes new and renewable energy generation and sales, Energy Storage System(ESS), Energy Prosumers, Electric Vehicle(EV) and EV charging infrastructure. If the New Business for Energy Industries develops, it will become an interactive market where consumers can equip themselves with batteries and new and renewable energy generation facilities to produce and sell electricity directly. In addition, a variety of suppliers, including large ESS, EV, and small-scale dispersed power, are expected to join the market. POSCO ENERGY is promoting New Business for Energy Industries in accordance with government policies and en-couraging technological development of electricity trading platforms.

Wind Power GenerationPOSCO ENERGY is promoting an on&offshore wind farm in Shinan-gun, Jeollanam-do, where wind resources are abundant. POSCO ENERGY began construction in February 2015 near Jaeundo Island and launched the commercial operation of 24MW in December 2016, 18MW in June 2017 followed by 20.7MW in May, Operation is steady, with a to-tal capacity of 62.7MW. The company is also promoting a 300MW of wind project near west Jaeundo Island. POSCO ENERGY is expanding the new and renewable energy busi-ness in accordance with the government's energy Policy.

Photovoltaic Power GenerationPOSCO ENERGY is producing energy with a photovoltaic complex with the capacity of 14.5MW utilizing the aban-doned salt pond in Shinan-gun, Jeollanam-do. By utilizing this disused area for photovoltaic power generation, the company can minimize environmental damages that can result from the construction of a new power plant while also producing eco-friendly energy. Also, POSCO ENERGY is actively responding to the RPS and securing stable prof-its by creating 2.8MW of photovoltaic power capacity using factory roofs, a floating photovoltaic system with a capacity of 50MW in the Gwangyang steel works slag landfill, and photovoltaic power generation in salty reclaimed land.

Virtual Power Plant(VPP)With the national project of developing the technology for a VPP operational platform, POSCO ENERGY is investigat-ing the feasibility of an electric power trading business. POSCO ENERGY was selected as a pilot company for electric power trading in October 2016 by the Korea Power Exchange. In May 2017, the company began technological

development with expert organizations using public R&D. In May 2018, the Electric Utility Act passed a bill allowing POSCO ENERGY to secure the power trading business in the market. In 2020, POSCO ENERGY plans to conduct a large-scale demonstration and feasibility check with the operational platform.

SRF Power PlantPOSCO ENERGY operates a Solid Refuse Fuel(SRF) Power Plant which recycles and treats daily waste and produc-es energy. As the first and largest SRF Power Plant built in Busan in 2013, it now produces 24.8MW of electricity per day for 57,000 households while treating 900 tons of waste. The amount of electricity produced is equivalent to replacing 70 million Nm3 of LNG annually, and has the same effect as eliminating about 174,000 tons of CO2. In the past, household wastes were incinerated and land-filled, causing a large amount of environmental pollution during their disposal. The SRF Power Plant separates and identifies combustible and incombustible wastes from daily waste, and only combustible waste is converted into fuel in the exclusive boiler for combustion to generate and sell electricity. In addition, the steam generated in the process has been supplied to the sewage sludge drying system near since January 2017, creating an additional profit of KRW 4.2 billion every year. Busan SRF Power Plant is pro-moting the expansion of steam supply to New International City and the Eco-Delta City of Busan. Busan SRF Power Plant set standards below the legal limit for treatment of major air pollutants. Moreover, It was awarded the Min-ister of Environment’s award for the efforts in pursuing green growth for Korea’s energy industry such as by re-placing fossil fuels, reducing greenhouse gas emissions, and dealing with the treatment of increased amounts of waste, thereby resolving environmental problems.

Sewage Heat Energy UtilizationThe Tancheon Sewage Treatment Center in Seoul process-es and discharges 1.1 million tons of sewage into the Han River every day. The water maintains a temperature of 12 degrees, even in the winter. POSCO E&E is collecting and recovering the heat energy generated from sewage water through heat pumps and supplying enough heat ener-gy(200,000 Gcal) to nearby local district heating corpora-tions to cover 20,000 households a year, replacing the use of 17 million Nm3 of LNG(fossil fuel) on an annual basis and reducing greenhouse gas emissions by 47,000 tons.

Stabilization of Facility OperationsStable Fuel Supply | In the power generation business, As fuel costs account for most of the power generation costs, stable fuel supply has a great impact on profitability and fa-cilities operation. POSCO ENERGY works to improve profitability and secure a stable LNG supply for the Incheon LNG combined cycle power plant by directly importing low cost LNG from overseas and signing long term supply agreements with KOGAS. In addition, in the case of the coal-fired power plant in Samcheok, it will secure global sourcing capabilities by using POSCO International, a general trading company within the group, as well as securing cost-effective and stable supplies through resources produced by overseas coal mines that a group affiliate, such as POSCO, has already invested in. POSCO ENERGY seeks to improve profitability by increasing the competitiveness of the Incheon Power Plant Unit 3 to the level of the most recent units, 7 and 9. In order to do so, POSCO ENERGY has signed a contract to directly import low-cost LNG for Unit 3 after the expiration of the current PPA(Power Purchase Agreement) and the entry into the CBP(Coast Based Pool) market.

Zero Outage(Trouble Free) | POSCO ENERGY prevents unexpected failures and eliminates waste factors through monitoring activities including QSS+(Quick Six Sigma Plus, innova-tive activity to increase quality, stability, and safety), and My Machine(facility performance restoration) in order to maintain facilities in an optimized condition. Moreover, POSCO ENERGY focuses on managing vulnerable factors through regularly planned prevention maintenance, a VMS(Vibration Monitoring System), and an online inspection system for high-voltage motors in order to control forced outages. At the same time, the company will continue to strengthen the commitment to maximizing facility efficiency and achieve zero outages through plant smartization.

Strengthening Operational Capacity | LNG combined cycle power plants require sophis-ticated technology to operate due to the nature of peaking power generation, where oper-ation is started and stopped frequently to respond to peaking electricity demand. As such, POSCO ENERGY is continuously striving to enhance the technology. Based on the 50 years of experience in power plant operations, POSCO ENERGY has some of Korea's top-level ex-perts and expertise in operation and maintenance. Moreover, POSCO ENERGY is conduct-ing tailored technique training to pursue the mid-to long-term goal of nurturing global level technicians. POSCO ENERGY is providing training and seminars to facilitate the vitalization of young employees in shut-down facilities, enabling organic collaboration between em-ployees to share operational experience, technology, and maintenance, thereby improving facility soundness.

Improving Profitability | POSCO ENERGY will promote improvement activities to increase efficiency in Gwangyang and Pohang off-gas power plants in various ways. When high vi-brations occur in the high-capacity rotating equipment of off-gas power plants, seawater pumps, boiler water supply pumps, equipment coolant pumps, gas coolant pumps or their motors, the power plant is shut down automatically. In order to prevent this, POSCO ENERGY developed the Pre-Diagnostic Smart Application for the abnormal signs in high-capacity ro-tating equipment. By cooperating with group affiliate, POSCO ICT, POSCO ENERGY analyzes the Big Data on past operational information of 17 units of pumps and motors, which makes it possible to take action before any failure occurs by identifying abnormal vibration and temperature signs. In addition, POSCO ENERGY will make efforts for improvement regard-ing heat control that affects the efficiency of off-gas power plants. In line with similar efforts made since 2016, the company implemented an optical H2 analyzer in March 2019 that works like the 'Optical CO analyzer’ developed in 2017 to take immediate and delicate action on the rapidly changing BFG heat when a furnace failure occurs in a steel mill.

High-Efficiency in Power GenerationSmartization of Power Plants | To stay abreast of the age of the Fourth Industrial Revo-lution, POSCO ENERGY implements smartization of power plants through the operation of Big Data facilities with an aim to create a 'High Efficiency, Zero Outage and Zero Accident Operation'. Using the accumulated experience and Big Data, POSCO ENERGY is promot-ing step-by-step, progressive changes in the management of the facilities for real-time performance analysis and power outage prediction. By utilizing signals from smart power plant applications, POSCO ENERGY will reduce fuel costs by maximizing the efficiency of facility operations. Moreover, the company plans to decreases outages by 50%, realizing accident-free business sites by implementing CBM(Condition Based Maintenance). This year, POSCO ENERGY will strengthen Smart Safety and refine the Smart Application which has been already built, and eventually expand Smartization to all business sites after 2020. POSCO ENERGY has established smart power plants for Incheon power plant units 7 to 9 and successfully decreased forced outages by 50% in 2018 compared to 2017(0.29%, 2017 → 0.14%, 2018 based on units 7-9).

Society With POSCO

POSCO ENERGY aims to engage in resolving social problems and promoting co-success with society and local communities. To pursue the management vision, 'Society With POSCO', POSCO ENERGY participates in resolving social problems, and all employees actively take part in POSCO 1% Share Foundation donation and volunteer work.

Interview with Stakeholders

Team Manager Kim Jisun , Habitat for Humanity Korea

Q1 | Habitat Korea works with POSCO ENERGY's 'Ener-gy Dream', a social contribution project, and strives to im-plement energy welfare and strengthen daily safety. Please share the social value points of the 'Energy Dream' project as well as Habitat Korea's values and the project's excellence in terms of social contribution.

A1 | First of all, the 'Energy Dream' project is closely related to POSCO ENERGY's business and is a project in which POSCO ENERGY can provide its expertise. I believe it was uploaded on the UN SDGs website because it is an ideal social contribution proj-ect which encourages active volunteer work among employees. In addition, Energy Dream is meaningful in that the project identifies risk factors in deteriorated living en-vironments in advance through electricity inspections and provides the beneficiaries with proactive measures to prevent accidents. POSCO ENERGY particularly focuses on providing a beneficiary-focused project. In the early stages, the project focused on providing electricity inspections. Now its scale has gotten bigger and it has evolved into an efficient energy construction project. Though the number of beneficiaries has been reduced slightly, POSCO ENERGY focuses on improving people's quality of life by expanding the scope of support for each household and improving the environment of poor neighborhoods, thus providing a better housing environment. 'Energy Dream' is

a sustainable project that supports people's self-reliance. This is in line with Habitat Korea's core values. I could say that it is a sustainable and meaningful project, not a one-time support, in that it establishes a foundation for local communities through efficient energy construction by cutting energy cost consumption.

Q2 | What commitments do you think POSCO ENERGY should make in order to create social value and pursue its management philosophy of 'Corporate Citizenship: Building a Better Future Together' for establishing a sustainable corporate history of 100 years?

A2 | There are three major areas to work on for a company to create social value. These areas are authenticity, sustainability and partnership. Even if a project is evaluated as a necessary social contribution, I have witnessed many cases where they are canceled or reduced in scale due to internal circumstances of the companies. That is why there are companies that do not engage in social contribution activities, and even for those that do, most of the projects are short-term and unsustainable. If there is an agreement within a company that it should take part in social contribution activities, the overall approach to the project, changes, including project scale and selection of beneficiaries and partnerships. These changes affect the performance of the project. In addition, there is a huge difference between designing and carrying out a project from a long-term perspective and accomplishing a short-term goal. Lastly, harmonious partnerships between stakeholders such as business executors are equally important. I believe the 'Energy Dream' project can be sustained for seven years and positively affect our society because POS-CO ENERGY successfully takes on the three roles of authenticity, sustainability and partnership. These efforts are important factors for realizing social value and leading POSCO ENERGY to become a more sustainable company.

Interview with Stakeholders

O&M Director Mr. Tyas, Indonesia PT Krakatau POSCO ENERGY(KDL)

Q1 | Please share your experience working in POSCO ENERGY and your thoughts about its corporate culture and various wel-fare systems. Also, please share your opinion about which area POSCO ENERGY should work on.

A1 | PT Krakatau POSCO ENERGY(KPE) was founded in 2011, and it is a power plant that generates electricity from Krakatau

POSCO steel mill utilizing off-gas as fuel. Most of the power plants in Indonesia gener-ate electricity from coal of natural gas, so an off-gas power plant is a new technology in the country. The Suggestion System that is currently being operated is an innovative activity that encourages employees to improve technology. Furthermore, employees are satisfied with working for the company with the corporate culture of safety-first as well as decent wages and good employee welfare. What POSCO ENERGY needs to work on now is boosting the morale of younger employees, especially millennials. There are few opportunities for younger employees to embrace challenges because of the industrial recession in Indonesia that has been going on since 2017. I hope that POSCO ENERGY will harness these existing systems which employees are satisfied with and find a solution to the challenges it is facing.

Q2 | What commitments do you think POSCO ENERGY should make in order to cre-ate social value and pursue its management philosophy of 'Corporate Citizenship: Building a Better Future Together' for establishing a sustainable corporate history of 100 years?

A2 | The company's CSR program is operating well due to financial support to im-prove public facilities and employees' efforts. The regional community education-al support system provides monetary support to talented students while POSCO ENERGY strives to harmonize with the local communities. These valuable efforts, recognized by both local communities and local governments, will contribute to the company's sustainable future while enabling effective communication and improving relationships.

Safety & Health Management

Feasibility of Selecting Material IssuesSocial awareness about the safety of employees, members of partners and local commu-nities is increasing. The importance of complying with strengthened domestic and inter-national safety regulations and coming up with standards that meet the requirements of stakeholders is growing as well.

Management ApproachSafety management issues at work sites can cause human injuries as well as negative effects on corporate image and financial or non-financial performances. Therefore, safety issues should be well managed. POSCO ENERGY works to improve the safety awareness of all employees by thoroughly managing the safety of its facilities, providing training and launching campaigns. In addition, POSCO ENERGY is making efforts to create a safe work-place for all employees and members of the partners.

09Strengthen ing the Safety and Health Management SystemIn 2018, POSCO ENERGY achieved ‘accident free’ status at all business sites through preliminary responses to changing laws and regulations while maintaining a thorough management system. In accordance with a pre-announcement of amendments to the Oc-cupational Safety and Health Act, POSCO ENERGY integrated 55 new regulations into the existing 158 safety and health management regulations. POSCO ENERGY is working with KOSHA 18001 certified companies and mandate a safety management plan. POSCO EN-ERGY has established a system to monitor the partners' safety capabilities and promote activities to ensure the safety of employees and stakeholders by distributing safety videos tailored to individual jobs. Apart from that, safety managers from business sites host volun-tary safety meetings and send out monthly safety letters to employees that include selected safety themes. POSCO ENERGY has systemized safety activities through feedback from monthly safety reports by the top-level executives. To strengthen the responsibility for safe-ty activities, in 2019 POSCO ENERGY plans to have accident-free items make up more than 10% of individual MBOs and also strengthen the incentive and punishment system regard-ing all safety activities and disaster liability.

Self-Driven Safety CulturePOSCO ENERGY has established an improvement system for autonomous risk discovery by promoting safety improvement activities such as Near Miss(cases that did not lead to actual accidents could have), Risk TOP system(improvement by es-tablishing quarterly plans for facilities with risk factors), and SAO(Safety Action Observation, a monitoring system that en-courages employees to self-monitor and make improvements in work practices). The employees voluntarily engage in and actively manage operations through self-directed Safety Spread activities and the partners support safety management in the field by following POSCO ENERGY's management standards. The key promotional activities derived from Near Miss analysis in 2018 focused on conduction, crash and falling accidents. In 2019 POSCO ENERGY will promote three basic safe-ty activities to achieve Zero Accidents, a part of company-wide KPIs. The plan is to strengthen the safety measures for three high-risk work activities(high, sealed, heavy work) in facility repair and operate safety training 10 minutes before the start of operations through an app from the Occupational Safety and Health Agency.

Overview Commitment Preparing for 100 years Corporate Citizenship Activities Activities and Performance Appendix 6160 CORPORATE CITIZENSHIP REPORT 2018

Though it is not a legal obligation, POSCO ENERGY is expanding safety management to the partners and overseas business sites. POSCO EN-ERGY is strengthening Facility Safety Management by applying a Risk Top 10 system identical to that of the headquarters and also planning to support the autonomous safety culture standards. In the case of PT Krakatau in Indonesia, proper safety management and environmental improvements have enabled a zero accident workplace. PT Krakatau plans to establish a safety culture to achieve zero accidents 24/7 through 'Habituation', 'Localization', 'Simplification', and 'Integration'. POSCO ENERGY has selected 'high temperature/high pressure equipment fa-cilities', 'toxic chemicals', 'toxic/asphyxiated gas', 'high-voltage electricity', and 'high-altitude facilities' as the 5 Core Safety Management Items and it is regularly inspecting high-risk electrical room, cable bundle, high-pressure gas storage, and firefighting facilities. Furthermore, considering that generation facilities mostly consist of precision/high-speed/high-voltage electrical equipment, POSCO ENERGY ensures a clean work environment 'New Factory Cultivation', 5S, and 'My Machine' activities every Friday morning. These activities have changed the perception of government offices and financial firms that power plants are hazardous facilities, and are having positive effects on the management environment.

Operation of a Safety CouncilIn accordance with the Industrial Safety and Health Act, POSCO ENERGY holds a quar-terly meeting of the Industrial Safety and Health Council to vote on major issues related to the safety and health of employees. Related programs are operated at business sites for all employees. Also, POSCO ENERGY holds monthly autonomous safety meetings for employees as well as monthly partner safety meetings for 13 resident partners to provide a safer working environment and to ensure the same level of safety as POSCO ENERGY. POSCO ENERGY looked at the safety equipment of 20 partners. Beginning February 2019, POSCO ENERGY is providing 7 major pieces of safety equipment, including safety helmets and safety boots, and taking action immediately if anything is damaged during operation. In addition, through risk evaluations, expansion of work environment measurements, and support for special physical examinations, POSCO ENERGY will expand the safety system for mutual growth. POSCO ENERGY plans to make revisions in guidelines for the work-place and working standards to put itself in line with the Industrial Safety and Health Act Sub-Legislation Legislative notice. Lastly, POSCO ENERGY will run an internal diagnosis of 32 PSM items that are closely related to the revisions.

Employee Health Promotion ActivitiesPOSCO ENERGY offers a weekly stretching session for all employees to prevent musculo-skeletal disorders, and mandate all employees, including the 268 engineers in the power plants, to wear proper safety equipment. Moreover, an intensive prevention activity for met-abolic syndrome is performed twice a year by health center employees. Employees who need care are offered fitness coaching and a tailored health care program including diet plans. In 2017, the '3W Campaign' was launched to create a healthy corporate culture. 3W stands for 'Water: Drinking more than 2L of water a day', 'Walking: Walking over 30 minutes a day', and 'Well-being: Following healthy diet plans such as low-salt meals', From June 2018, POSCO ENERGY has been encouraging employees to walk more in their daily lives through the mobile app, 'Walk on'. With this app, employees can set their own goals and accomplish them. The 'Walking Challenge' rewards employees with good performances, which leads to a more active participation of employees in health-promoting activities. As of March 2019, the number of participants was 347, a 171% increase from June 2018(202). The average number of steps taken was 9,494, a 148% increase from 6,419 in June. Seoul City presented POSCO ENERGY with an award in October 2018 for launching the Walking Campaign.

Correlation to Business

Communication with EmployeesPOSCO ENERGY is promoting various activities to cultivate a collaborative management culture and effective commu-nication. The CEO provides opportunities for direct sug-gestions from employees to high-level executives through meetings across business sites, departments, and divi-sions and 'Walking Seonjeongneung with the CEO'. POSCO ENERGY also provides many opportunities for communica-tion through organization vitalization, lectures in human-ities, workshops, Hope(Hof) day, and sports days. In 2019, POSCO ENERGY is continuing to promote communication activities such as a company history quiz event and story contests in celebration of the 50th anniversary of the foun-dation.

Labor-Management CultureLabor-management culture is one of the key indica-tors that determine a company's competitiveness. The WEF(World Economic Forum) considers the labor-man-agement cooperation index to be a major indicator when determining a nation's competitiveness in the labor market sector. At times where corporate competition is growing, promoting global-level labor-management cooperation is no longer a matter of choice. POSCO ENERGY encourag-es an advanced labor-management culture with its labor union and three labor-management councils, the power generation council, fuel cell council and energy council. POSCO ENERGY strives to improve employee welfare and the working environment through biennial negotiations to conclude collective agreements and by engaging in efforts such as improving human resources and labor systems, staffing and training plans. Moreover, POSCO ENERGY is running Grievance Resolution Committees under the councils of each business site to deal with employee griev-ances. The Grievance Resolution Committee guarantees confidentiality regarding employee grievances and sugges-tions while establishing a system to deal with grievance issues in the regular labor-management council meetings every quarter. Furthermore, POSCO ENERGY encourages the communication and trust-building of labor-manage-ment by regularly opening labor-management workshops. POSCO ENERGY's Indonesian power plant runs monthly work councils and recognizes union free management. In Indonesia, POSCO ENERGY is working to stabilize la-bor management relations by holding biannual meetings

where family members of married employees are invited to attend(68 percent of the workforce), and listening to em-ployee opinions and suggestions through a wish box. Along with this, POSCO ENERGY is strengthening the sense of bonding among employees through various activities such as a Korean culture experience program, POSCO field trips, an organization vitalization program and sports day in which all employees participate, visitations to workers by on-site supervisors, support for one club activity per per-son, picnic meetings, employee birthday parties, congratu-latory letters and presents for anniversaries, and exchange programs between Korean and Indonesian employees.

Employee BenefitsThe employee welfare system is the key to managing em-ployee happiness. Happy employees lead to happy custom-ers, and this eventually leads to a sustainable and sound corporate culture. To create 'a company where employees want to work' has become the aim of many companies as more employees begin to value a balance between work and life. POSCO ENERGY focuses on maternity protection and child care support in order to foster a family-friendly management. POSCO ENERGY offers a maternal care pro-gram that includes a reduction of working hours for preg-nant women, parking tickets for better convenience, and an in-house maternity lounge. Moreover, POSCO ENERGY offers parental leave for a maximum of two years and make sure employees are not disadvantaged in promotions or employee evaluations due to parental leave. On top of the parental leave guaranteed by law, employees receive celebratory gifts for birth and pregnancy. Moreover, POS-CO ENERGY supports the employees with a 'psychological counseling center' and the 'family counseling program', while providing various forms of support to promote the leisure and welfare of employees such as health check-ups for spouses, medical expenses, congratulatory gifts, and tuition for the children of employees. To help solve the so-cial issue of low fertilitrates, POSCO ENERGY plans to build more in-house kindergartens. Since 2013, POSCO ENERGY has been running an in-house kindergarten in Incheon Seo-gu to support childcare. POSCO ENERGY will expand and relocate this kindergarten in 2019 to accommodate 10 more children, hence accommodating 30 children in to-tal, and improve the facility. In 2012, POSCO ENERGY was certified by the Ministry of Gender Equality and Family as a 'family-friendly company' for the first time among domestic IPPs, and in 2015 and 2017 acquired recertification.

Work-Life Balance

The 52-hour work week POSCO ENERGY strives to strike a balance between work and life among its employ-ees. To start with, POSCO ENERGY has implemented a flexible working hour system. In compliance with the government's '52-hour work week' policy, POSCO ENERGY has implemented flexible working hours for the power generation division where most of the work is planned ahead, and selective working hours for the fuel cell division and headquarters where most of the work is spontaneous. Furthermore, employees have the freedom to choose when to come to work between 7am and 11am. POSCO ENERGY aims to support the employees' self-development, childcare, and education through this flexible working hour system. In addition, the working hours saving system, which is gaining support from employees, allows employees to save up overtime working hours and use them later. Employees are content with the implementation of 'family day', which allows them to leave work one hour early every Friday. To promote the work & life balance of employees, POSCO ENERGY came up with a 'work & life day' system that encourages employees to take leave during bridge holidays. Moreover, a pop-up window appears on employee's screens every day when it is time to leave the office.

By implementing efficient working methods to minimize ineffectiveness in management, POSCO ENERGY is encouraging management-level improvements giving directions, reporting, and meetings. In 2018, POSCO ENERGY selected a pilot department to come up with methods of efficient management by ▷minimizing re-ports(e-mails, verbal reporting principle) ▷promoting business manners for communication vitalization ▷ and standardizing reporting methods. This year, POSCO ENERGY plans to promote ▷ working without team(includ-ing group/department section/division) unit reports ▷ and the Real Name Report System(RAI*), in order to change the executive-led management system. With these efforts to improve inefficient work systems, POSCO ENERGY aims to promote work & life balance and allow employees to focus on work that holds intrinsic value, hence bringing real change for all employees. At the end of the working day, POSCO ENERGY notifies workers through pop-up windows to leave the office, and employees who wish to work overtime can register for overtime work in advance. This prevents employees from unnecessarily working overtime and allows them to plan their working hours if they are to work overtime. * RAI: Responsible, Accountable, Informed

As such, POSCO ENERGY provides programs for 'strengthening the training of glob-al players', 'systematic training of experts', 'improving the leadership of trust and communication', and 'career acti-vation development system'. Furthermore, POSCO ENERGY engages in support activities to strengthen the job compe-tency of employees through overseas expert training and innovation activities.

Operation of the Board of DirectorsThe BOD holds general meetings, and according to the company regulations and articles, the CEO appointed by

the BOD is also the chairperson of the BOD. In principle, BOD meetings are called by the CEO and resolutions can be made with more than half of the BOD members in at-tendance and a majority vote of the attending members. To prevent any conflicts of interests, it is indicated in the corporate bylaws that no BOD members with a special stake in the company can exercise voting rights at relevant meetings.

A Fair and Transparent TransactionPOSCO ENERGY has adopted a transparent procedure from selecting, contracting and paying for a purchase to assessing partners to create a fair and transparent transaction culture. POSCO ENERGY utilizes the e-Procurement system in concluding contracts, and the executive in charge of purchasing supervises and runs the Subcontracting Deliberation Committee when needed to self-evaluate compliance with the Subcontractor Act. Through POSCO's SRM(Supplier Relationship Management) system, POSCO ENERGY is able to en-hance fairness in the assessment of partners while encouraging them to fulfill their social responsibilities in the areas of environment and safety during registration and assessment. For partners who comply with the system voluntarily, POSCO ENERGY offers incentives in an effort to strengthen the competitiveness of the outstanding partners.POSCO ENERGY conducts yearly evaluations and collects supplier's opinions(or objections), thereby evaluating the SG(Sourcing Group) and suppliers as Excellent, Good or Poor. More-over, to promote mutual growth, POSCO ENERGY operates a bidding system that prevents excessively under-bidding and reflects a fair margin. To prevent a decrease the supply quali-ty of partners due to excessive bidding competition, POSCO ENERGY uses either the market price competitive bidding system or the price restriction bidding system rather than the op-timum bidding system for certain items. Partner Support ProgramTo provide help for small-and medium-sized partner companies in dealing with financial difficulty, POSCO ENERGY makes purchase payments in 100% cash, twice a week, so that payment can be received a maximum of five days after the receipt of a product. In 2019, for simple services, minimum wage will be paid and the contract term will be lengthened to 3-5 years from 1 year to secure employment stability. Moreover, quality assurance assessments will improve the purchasing system to promote co-success with suppliers. In addition, POS-CO ENERGY promotes mutual growth by providing in-house funeral service support and sports facilities, both of which are available the to the employees of suppliers.

Supply Chain Management

Multiple EvaluationsTo improve the top-down evaluation system where one senior employee evaluates team members, POSCO ENERGY has implemented a multiple evaluation system that includes evaluations from a senior employee, a subordinate employee, a fellow employee, and cus-tomers. This process involves various evaluators and can improve the fairness and objectivity of employee performance assessments.

RewardsThrough a performance-linked annual salary system, a compensation system based on roles and jobs has been implemented, and fair compensation is achieved through a perfor-mance incentive system based on competence and degree of experience.

Based on a report originally in Korean

The Board of Directors and ShareholdersPOSCO ENERGY Co., Ltd.:

Opinion We have audited the consolidated financial statements of POSCO ENERGY Co., Ltd. and it`s subsidiaries(the “Group”), which comprise the consolidated statements of financial posi-tion as of December 31, 2018 and 2017, the consolidated state-ments of comprehensive income(loss) change in equity and cash flows for the years then ended, and notes, comprising sig-nificant accounting policies and other explanatory information.In our opinion, the accompanying consolidated financial state-ments present fairly, in all material respects, the consolidated financial position of the Group as of December 31, 2018 and 2017, and its consolidated financial performance and its con-solidated cash flows for the year then ended in accordance with Korean International Financial Reporting Standards(“K-IFRS”)

Basis for Audit Opinion We conducted our audits in accordance with Korean Standards on Auditing(KSAs). Our responsibilities under those standards are further described in the Auditors` Responsibilities for the Audit of the Consolidated Financial Statements section of our report. We are independent of the Group in accordance with the ethical requirements that are rel-evant to our audit of the consolidated financial statements in Republic of Korea, and we have fulfilled our other ethical re-sponsibilities in accordance with these requirements. We be-lieve that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Other Matter The procedures and practices utilized in the Re-public of Korea to audit such consolidated financial statements may differ from those generally accepted and applied in other countries.

Responsibilities of Management and Those Charged with Governance for the Consolidated Financial StatementsManagement is responsible for the preparation and fair presen-tation of the consolidated financial statements in accordance with K-IFRS, and for such internal control as management de-termines is necessary to enable the preparation of consolidated financial statement that are free from material misstatement, whether due to fraud or error.In preparing the consolidated financial statement, management is responsible for assessing the Group`s ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basic of accounting unless management either intends to liquidate the Group or to cease operation, or has no realistic alternative but to do so.

Those charged with governance are responsible for overseeing the Group`s financial reporting process.

assurance about whether the consolidated financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditors` report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with KSAs will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reason-ably be expected to influence the economic decision of users taken on the basis of these consolidated financial statements.

As part of an audit in accordance with KSAs, we exercise profes-sional judgment and maintain professional skepticism through-out the audit. We also:• Identify and assess the risks of material misstatement of the

consolidated financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.

• Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Group`s internal control.

• Evaluate the appropriateness of accounting policies used in the preparation of the consolidated financial statements and the reasonableness of accounting estimates and related disclosures made by management.

• Conclude on the appropriateness of management`s use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Group`s ability to continue as a going concern.
