India Has Great Renewable Energy Potential

Source *Potential (MW) Installed (MW) as on Jan’12

Wind Power 45,000 16,179

Biomass 16,000 1142

Small Hydro 15,000 3300

Cogeneration-Bagasse 3,500 1952

Waste to Energy 2,700 74

Solar Unlimited 940 Source: * MNRE - Development of Conceptual Framework for REC Mechanism,2009

• Wind energy constitutes largest commercially exploited RE source in India.

• RE capacity is 12% of total grid installed capacity base

• Very little RE potential has been tapped

Today, Solar power is merely 0.22% of RE power

But potential of Solar power in India is far more than other RE sources

India emerged as the 2nd most attractive country on overall solar index

Rank Country Solar Index Solar PV Solar CSP

1 USA 72 71 74

2 India 64 69 53

3 China 61 66 47

4 Spain 58 56 63

5 Italy 58 64 65

Solar energy potential is virtually infinite Daily solar radiation 4-7 kWh/m2/day 250-300 sunny days in a year 5000 trillion kWh solar radiation incident in yr Indeed, at present efficiency levels, 1% of land area is

sufficient to meet electricity needs of India till 2031

Interesting Statistics Gujarat & Rajasthan States have the highest intensity

of radiation (6.4 – 6.6 kWh/m2/day) 3500sq.km of area in Rajasthan/Gujarat sufficient to

produce 750-2100 GW

O&M Practices For Solar Projects

Plant Monitoring (at String Level) & Recording Data

Maintenance Strategy

Monitoring of Solar modules performance.

Performance analysis of strings / JB.

Monitoring the performance of solar Inverters

Monitoring plant availability, PR and CUF on daily basis.

Time Based Maintenance (TBM):- Monthly, Quarterly, Half Yearly and

Annually.

Corrective Maintenance:- 24x7 team available for restoration of Breakdowns.

Predictive Maintenance:- Predictive maintenance methodology like thermal

Imaging and walkthrough routine checks.

Improvement and up-gradation Maintenance :- Maintenance for

enhancement of performance of equipments and plant in Quality, Safety and

Productivity domains.

16


Daily & Monthly Performance Data Reporting

Liaoning With State Utility ( EB) For JMR & Billing Support To Customers

Report Generation and submission to customer on daily and monthly basis.

Major Breakdown analysis for RCA and CAPA.

EHS report generation on monthly basis.

Deviation analysis reports for analysis w.r.t. benchmarking of performance

indicators.

SCADA Monitoring as a optional if Available.

Coordination with State Utility- EB for JMR and billing support to customer for

timely payments.

.


17

Other Scope

Legal compliances / Periodical Inspections by Electrical Inspector

Security management.

Customer Interface.

CDM Validation and Audit.


Conditional Monitoring - Thermography

Thermography Test Report:- By Thermal Imaging we are

providing rectification before failure,

Identification of hot spot in Inverter, Electrical

panels, Modules under predictive maintenance.


18


Solar Module Cleaning Methodologies

Medium pressure vehicle

mounted cleaning system


19

Medium pressure Manual

movable cleaning system.



Alternative Module Cleaning Methodology

20

High pressure vehicle mounted

cleaning system

Medium pressure fixed type

cleaning system


Challenges for O&M Services

Module Cleaning Timing ( 11:00 -17:00 Hrs is no Cleaning time to

avoid hot spot / Micro cracks on modules mainly during summer April

to August).

Optimizing water conservation, improving Cleaning speed, minimize

vehicle movement at site to reduce dust diposition on module.

Safety aspect during predictive maintenance like checking set

parameters limits Vs actual tripping/ alarm, Thermography of

Electrical panels/ PCB’s/ Contactors etc.

PM activities AS PER CHECK LIST only during Non Generating Hrs

during mainly night time/ early morning ( from Sun Set to Sun Rise).

21


Challenges for O&M Services

Optimising Auxiliary Consumption based on design and

execution during EPC ( 1-1.5%),

Availability of Inverter spare parts at site.

Inverter suppliers are not considering to train & Develop

service Engineer as certified Service Engineer for fault

rectification rather insisting on “CALL Basic”

Restricted Data Transfer protocol by Inverter suppliers to

SCADA system developed by Owner.

Inverter suppliers Insisting Developers to enter in AMC post

warranty which is highly expensive with no option left.

Major Warrantable coverage's in CSP, PV Based Solar Plants

Import Equipments

Solar Inverters

Solar Tracker

Solar Modules

Turbo Generators

Solar Collectors

Indigenous Equipments

Electrical Switchyard Equipments

Transformers

Inverter Shelters

Electrical Drives and Pumps

Water Treatment Facilities

Module Cleaning systems / Capital test Equipments

Miscellaneous items like cooling towers, boilers, auxiliaries 24

Warranties and Post-warranty Risks of O&M of Solar Projects


Warranties and Post-Warranty Risks of O&M of Solar Projects

Why Warranties Required for Import Equipment

Lack of Expertise knowledge on Inverter specially on Control

Cards/ Sensors,

Lack of Indigenous Vendor Availability,

Non availability of spare parts in open market

inventory levels for cost optimization,

Monopolistic approach of Inverter and module manufacturer,

Warranty and extended warranties are must to keep plant fully

operational

How to Achieve?

Ensure extended performance warranty with manufacturer / supplier for life of

product in terms of annual availability with spares supply.

Response and Resolution time in case of failure of equipment To ensure

optimized plant availability to safe guard investment and returns.

25


Post Warranty Risks Involved

Sustainable Performance of plant,

Infrastructure created to meet requirement

Lack of Independent Solar O&M expertise,

Indigenous Vendor development,

Availability of Spares for imported equipments,

Technological Change / Up gradation,

Degradation of equipments efficiency

Availability of Imported spares when required

26

Warranties and Post-Warranty Risks of O&M for Solar Plants


Key Parameters for Assessing O&M Service Provider

Experience in operating Solar Plants in India with track record

Technical Expertise with Back end support

Quality of manpower deployed with industry knowledge

Indigenous Vendor development for services,

Working Experience with different suppliers/ developers to understand

different technology,

Monitoring and Reporting performance data as agreed on Daily/

Monthly Basis methodology

Infrastructure availability for PM, BM, Predictive Maintenance

Selection of Module Cleaning / Capital equipments technology

Legal compliances to ensure no deviation from any Govt. Rule.

Reputation & Brand image in Solar Industry to give confidence in

plant operation

Services Quality are complied / certified for EHS & Quality as per

ISO Standards. 27

Points to consider while selecting O&M service Provider


Poor O&M can lead to loss of Generation of Revenue

Warranties may be withdrawn by suppliers due to non compliances

Plant life likely to be reduced due to improper timely maintenance

Increase in major Breakdown of Equipments

Local Disputes with local villagers / stack holders may increase if not

taken care in time

Capital assets / Equipments if not taken care may lead to premature

failure from its designed life cycle

Stoppage of Generation payment cycle from state utilities for non

compliances of its guidelines.

How Poor O&M Services can Mismanage Solar Plant

Revenue Generation High with long term sustainability Low Revenue short term sustainability

Legal Compliances 100% partial to cut cost

EHS and quality as per ISO Standard fully compliance Partial

Frequency of Breakdown Low High

Soiling Losses ( Revenue Losses) low High

Housekeeping / Up keep of plant High level Medium/ low level

CDM audits / Insurance Assistance 24 x 7 need to arrange on case to case basis

Identifying module degradation at string level & Take actions Yes No

Man Power supply Skilled Fully trained for Solar plant Semi Skilled Manpower

Site Over All Management / Reporting highly skilled in charge with some exposure to Solar

O&M Cost / MW Rs 10-12 Lacs / MW

( Long Terms Revenue Gain) Rs 8-10 Lacs / MW ( Short Term Revenue Gain )
