Tata BP Solar commissions first MW solar plant under RPSSGP in Tamil Nadu in India

 According to reports, Tata BP Solar India Ltd, a joint venture of Tata Power and BP Solar, has lived up to its reputation as the pioneer and market leader in India and is the first company to have installed and commissioned a megawatt scale solar power plant under the Rooftop and Other Small Solar Power Generation Plant scheme administered by IREDA under the Jawaharlal Nehru National Solar Mission (JNNSM).

This landmark project is owned and developed by B & G Solar Private Limited at Komal West Village, Mayiladuthurai in Tami Nadu. The one megawatt plant was synchronised to the grid on 10 June, which is a good three months ahead of the scheduled date of start of 16th September 2011.
K Subramanya, CEO, Tata BP Solar, said: “This is a milestone in the rapidly developing Indian solar story. Tata BP Solar team as the engineering, procurement and construction (EPC) contractor worked hard and in tandem with the B&G Solar team to achieve completion of the project well ahead of time. The plant was put up in a record time of 150 days.”
This project uses 4400 number of crystalline silicon modules of 230 Watts each spread out over an area of 5.5 acres. These modules will generate electric current when solar radiation falls on them. This DC (direct current) electricity will be converted to AC (alternating current) through inverters and upgraded to 11 KV via transformers so that it is fed into the electricity grid lines of Tamil Nadu Electricity Board at 11 kV. The solar power plant will generate 1.49 mn units of electricity per year.

Tata BP Solar has also taken the contract to provide the Operation and Maintenance (O&M) services to the plant for the first 10 years after commissioning. The plant is designed to run for 25 years and the crystalline silicon modules manufactured and supplied by Tata BP are guaranteed to perform for this period of 25 years with minimal degradation in the power output over the long life time. B&G Solar has signed a Power Purchase Agreement (PPA) with the TNEB for 25 years to supply this power to them.
The Chairman of B&G Solar, Dr. V. Bhaktavatsalam , stated: “I am delighted to be the first one to commission the solar plant out of a total of 80 such plants totalling 100 megawatts coming up all over India under the rooftop solar plants scheme of the IREDA (Indian Renewable Energy Development Agency). I look forward to the other such plants coming up in the country in the next few months.”
Tata BP Solar has been able to secure the largest number of EPC contracts in the IREDA- run scheme and is currently executing around 15 such projects in different parts of India including Tamil Nadu, Andhra Pradesh, Maharashtra, Chattisgarh, Orissa, Jharkhand, Uttarakhand and Rajasthan.


  1. Has Tata BP Solar agreed to recycle the panels after their useful life of 25 yrs like their competitor First Solar does internationally? Disposal costs for Silicon Arsenate, an environmentally hazardous material during plant decommissioning, needs to be factored into the project’s capital and environmental budget.
