The commissioning is part of the company’s plan to expand its renewable energy portfolio to 1,000MW by 2017.

Located in Rajgarh, Madhya Pradesh, the 50MW project is considered as the largest Indian solar project to use indigenously-built solar modules to help offset approximately 73,000 tonnes of CO2 in the first year.

NTPC Director (Technical) Jha said the solar power generation capacity in NTPC has reached 95MW with the commissioning of Rajgarh solar project.

"We, at NTPC, are increasing our focus on renewables, in particular solar energy," Jha added.

Expected to generate 78.66 million units (kWh) of energy per year, the plant will supply electricity for around 90,000 households in a year.

Tata Power Solar CEO Ajay Goel said, "This project bears testimony to Tata Power Solar’s 25 year strong lineage and the ability to bring together our strengths in manufacturing world-class solar modules and EPC (engineering, procurement and construction) capabilities."
