India’s first solar PV project registered under the CDM

On 16th May 2011, India’s first 5 MW of installed capacity solar power project registered under the Clean Development Mechanism that uses solar PV technology for power generation.  This project is now eligible to earn carbon revenue from year 2011 onwards. Please find following details relevant to the project activity;

Revenue of SIIPL CDM Solar PV project


Technical description

  1. The project activity is solar photovoltaic based power generation. The rated capacity of the power plant will be 5MW at standard test conditions of 1000W/m2 solar radiation, 250C ambient temperature and 1.5 Air mass.
  2. North south oriented and layout with flat panel of thin film type modules of PV array
  3. Capacity of each Module is 78W (P) / any other compatible size.
  4. Inverters Capacity – 500 kW each
  5. Land area – 66 acres
  6. The DC electric power generated by the photo voltaic modules are converted into 415V, 3 phase, 50Hz, AC power in a number of outdoor inverters, stepped up to 11000V through a set of outdoor transformers located in a distributed manner all over the plant.
  7. The total power generated will be stepped up to 110kV in a 6.3MVA, 11/110kV power transformer with its associated 110kV outdoor switch gear located in a switch yard for interconnection to the 110kV transmission line of TNEB.
  8. Plant load factor: 19%
  9. Grid emission factor: 0.944793 tCO2/MWh


We are expecting more solar PV based Indian CDM project in near future. Following table shows solar PV CDM projects under the validation stage from India;


CDM solar PV projects under the validation-India

The amount of solar energy produced in India is less than 1% of the total energy demand. The grid-interactive solar power as of December 2010 was merely 10 MW (Read more on Indian electricity scenario). Government of India has taken initiative to promote solar energy in the country and have started Jawaharlal Nehru National Solar Mission (JNNSM) in 2010 (as a part of NAPCC).  Under the JNNSM, a total of 150 MW (each for 5 MW) of grid connected solar plants were awarded to 30 companies by Dec 2010.  JNNSM include generation based incentive to the each kilowatt hour of power produced by solar PV project and as a result of it, solar PV based power plants are becoming an exciting business opportunity. Carbon credits projects based on solar PV technologies are also helping the project developers to cover their project cost associated with the technology and equipments.
