How did it happen
Full marks to Govt of Punjab for the initiative
We presented concept paper to Chief Minister Punjab in May 2013 to set up 1000MW solar power plant
Highest quality products
Lowest possible price
Fastest execution time (months not years)
Financing available from China
Tariff would compete with other technologies and bring the basket price downwards
CM sent a professional team to China to study and evaluate
MOU signed with TBEA to meet the promise
Solar Park was established in Bahawalpur in Cholistan
International tenders were called for first 100MW plant after due pre-qualification process in which 12 international companies were pre-qualified
After competitive bidding, TBEA was awarded contract being the lowest qualified bidder and meeting requirements of due diligence

During 2014, TBEA constructed over 1,500MW of solar power plants
Largest manufacturer of transformers in the world, with capacity to
build the largest size transformers to highest standards
Largest manufacturer of cables in China
One of the two largest manufacturers of inverters in China
Own manufacturing of combiner boxes, solar panels

Cost of Electricity
Latest NEPRA Tariff (January 2015)
North Region – US cents 14.7588 to US cents 15.0279
South Region – US cents 14.1516 to US cents 14.4096
Above rates are maximum, with downwards adjustments for savings based on
Power produced in excess of capacity factor of 17.5% for North and 16.78% for South
Construction Period Interest
Plant Insurance
Loan interest rates (KIBOR / LIBOR plus)
Final rates paid to IPPs could be as low as 12 cents

Pakistan and issues for solar
technology Manufacturing
Solar panels (silica processing, ingots, wafers, cells, modules)
Inverters
Transformers / Switchgear, Substation Equipment
Structure
Cables, etc
Standardization and Test Laboratories
Systems design and engineering
Development of companies in engineering, consulting, execution, O&M and other services
R&D
Manpower training / Capacity building
![Page 34: Pakistan's first 100MW Solar Power Plant](https://reader037.vdocuments.site/reader037/viewer/2022102811/586692e91a28ab10408b7f6f/html5/thumbnails/34.jpg)
Issue – Quality of Products
We are a cost conscious nation
Do not understand meaning of quality particularly in case of Solar Technologies
Most of the products entering Pakistan market are junk with claims of 25 year life or even performance. How do you ensure?
How do you recognize difference in quality? Case of top Chinese manufacturer with
Economy Model (made for Pakistan, India and Sri Lanka only)
Standard Model and
International Standard Model
Role of Government in ensuring quality
![Page 35: Pakistan's first 100MW Solar Power Plant](https://reader037.vdocuments.site/reader037/viewer/2022102811/586692e91a28ab10408b7f6f/html5/thumbnails/35.jpg)
Some conclusive thoughts
IPPs will be set up under NEPRA tariff regime
Set up of standards for solar?
Set up of standardization and testing laboratories to ensure quality and certification?
Academics and R&D – capacity building
Explore natural resources for raw materials
Find investors who will invest into processing and manufacturing on large scale to produce quality and quantity
Develop consulting houses and engineering companies for design and execution
Examine how we can compete internationally without subsidies
Move away from off-grid systems to on-grid systems for homes and commercial applications with net metering
