India needs to build solar-electricity storage system

India needs to build a storage system for electricity from its fast-expanding solar network in a bid to balance cost-effective energy mix. There is a mismatch between peak demand and electricity generation period for solar, said Mr Nitya Nanda, Fellow & Area Convenor at the Centre for Resource Efficiency and Governance, TERI. Mr Nanda expressed concern over the high cost of storage system, mostly to be a battery-based set up. This would raise the solar electricity cost to consumer to Rs 10 per 2.5 kV, from just nominal right now, he said.
