Policymakers and regulators should build the necessary framework for integrating rooftop solar and battery storage with electric vehicles (EVs) to achieve a sustainable and vibrant future, according to a new report from the Institute for Energy Economics and Financial Analysis (IEEFA).

India has set a massive 450 gigawatts (GW) renewable energy target by 2030 and aims to become a 100 percent EV nation by 2030.

“Combining solar roofs with state-of-the-art storage and batteries and EVs, or mobile batteries, is very close to India,” said Vibhuti Garg, author, and economist, who leads India, IEEFA.

However, he added that the opportunity to consolidate renewable energy is not available which could increase the benefits of integrating solar roofs with minimal storage, smart devices in demand, and EVs.

According to the report, policymakers will need to make the technical integration of these DER resources a priority.

“Combining rooftop solar with storage and EVs is important. It is very costly for private and public consumers to distribute energy-efficient chargers and charge EVs directly using solar radiation,” said Gabrielle Kuiper, co-author, DER expert, and IEEFA guest provider.

IEEFA in its report said that managing the charging and discharging of EVs and automotive-grid technology – enabling power to be delivered or grid when needed – could change the game in India.

He also added that an additional indicator of daytime prices to promote supply at peak demand times will provide much-needed flexibility to the Indian grid as the number of renewable energy sources grows.

According to Garg, DISCOMs can play a key role in facilitating a system where distributed energy resources such as solar roofs, battery storage, and EVs are centralized, planned and operated, to drive power outages and sustainable energy for all.
