Policy makers and regulators must build the framework required for combining rooftop solar with battery storage and electric vehicles to meet Prime Minister Narendra Modi’s vision for a sustainable, energy-secure future, according to a new report from the Institute for Energy Economics and Financial Analysis (IEEFA).
In addition to the ambitious renewable energy target of reaching 450 gigawatts (GW) by 2030 and media reports suggesting consideration of a mid-century net-zero emissions target, Prime Minister Modi wants India to be a 100% electric vehicle (EV) nation by 2030.
“Combining rooftop solar plus storage in the form of batteries and EVs, or mobile batteries, are in India’s near-future,” says co-author Vibhuti Garg, IEEFA Energy Economist, Lead India.
“Policy initiatives by central and state governments are already boosting the adoption of EVs, and although slow, rooftop solar and battery uptake is increasing.
“What’s missing however is the opportunity to integrate distributed energy and therefore maximise the benefit of combining rooftop solar with small-scale storage, smart demand-responsive appliances and EVs.”
“Combining rooftop solar with storage and EVs is key,” says Dr Kuiper. “It is more cost effective for private and public consumers to have distributed charging co-located with power generation and to directly charge EVs using behind-the-meter solar.”
Managed charging and discharging of EVs and vehicle-to-grid (V2G) technology – which enables power to be drawn from or supplied to the grid when most needed – could be a game-changer for India.
According to Garg, distribution companies (discoms) could play a greater role in facilitating a system where distributed energy resources like rooftop solar, battery storage and EVs are central, planned for and taken advantage of, driving deflation and sustainable energy for all.
