Call to de­velop an­cil­lary stor­age in­dus­try for re­new­able en­ergy

The Hindu Business Line - - NEWS -

With the cost of re­new­able en­ergy com­ing down and the mar­ket po­ten­tial ex­pand­ing, an an­cil­lary in­dus­try for stor­age is the need of the hour, said PC Maithani, Ad­vi­sor, Min­istry of New & Re­new­able En­ergy.

Speak­ing at the 6th In­ter­na­tional Con­fer­ence and Ex­hi­bi­tion on En­ergy Stor­age, EV & Mi­cro­grids, here on Thurs­day, Maithani said the chal­lenge with go­ing purely so­lar or wind is that so­lar is avail­able only in the day and wind en­ergy gen­er­a­tion can hap­pen be­tween April and Sep­tem­ber.

For in­stance, when so­lar pan­els come un­der cloud cover, the volt­age drops till the cloud passes. “We can start by see­ing if we can store enough en­ergy for 10 min­utes. An an­cil­lary in­dus­try for stor­age can look at de­vel­op­ing sep­a­rate stor­age for so­lar and wind and a hy­brid sys­tem,” he added.

Praveer Sinha, CEO & Man­ag­ing Di­rec­tor, Tata Power, said it is im­por­tant at a time when grids are be­com­ing com­plex and is a huge chal­lenge as elec­tric ve­hi­cles are com­ing in.

On the other hand, Sinha said in the last 10 years, the stor­age busi­ness has grown 25 per cent and ac­cord­ing to pro­jec­tions would grow by 20-25 per cent in the next 10 years. “There is a huge mar­ket po­ten­tial. Op­por­tu­ni­ties are com­ing from dif­fer­ent as­pects such as EVs and mi­cro­grids in vil­lages,” he added.

“We are also see­ing so­lar prices go­ing down, which will in­crease pen­e­tra­tion. But we need to make re­new­able en­ergy sus­tain­able. This is where bat­ter­ies come in,” Sinha added.
