TERI & BRPL To Study PV Rooftop Grid Effects

• TERI and Delhi utility BRPL have come together to study the challenges of high penetration of rooftop solar power capacity to the grid
• With the help of case studies of other distribution companies in the country, TERI will analyze the challenges and offer solutions for large amounts of grid-connected PV rooftop systems
• BRPL will assist TERI with requisite data to select suitable feeders in its consumer mix, load pattern, among others
• TERI plans to finish the study in a year's time  

The Energy and Resources Institute (TERI), an Indian energy research institute, has joined hands with BSES Rajdhani Power Limited (BRPL) to help smooth large-scale PV rooftop penetration in India. TERI will carry out a study for technical challenges and solutions for renewable energy grid integration with focus on rooftop solar. Studying the cases of a few distribution companies in the country, it aims to understand the challenges that distribution grids may face with high amounts of PV rooftop capacity added.

"BRPL is prepared to accept the challenges of incorporating large scale rooftop solar and electric vehicles into distribution system rather opposing the same," said Amal Sinha, CEO BRPL.

BRPL is a joint venture between private firm Reliance Infrastructure Limited and the Government of NCT of Delhi. BRPL and its sister company BSES Yamuna Power Limited (BYPL) supply electricity to two-thirds of Delhi. Last October, BSES announced that it had installed over 200 rooftop PV systems in Delhi with a total capacity of 7 MW (see Net Metering Progress In Delhi).

The two partners will identify and finalize different areas of carrying out studies related to rooftop PV development, including technical and commercial issues. BRPL will assist TERI with data to help select suitable feeders based on the consumer mix, load patterns and the like. The study is expected to be completed in a year's time.
