Indian utilities contemplate coal – rather than energy storage – to balance renewables
The Ministry of New and Renewable Energy has specified how grid back-up capacity procurement will work for Indian electricity distribution companies. The rules consider energy storage solely as part of the 51% clean energy requirement, and instead use coal – with a variable price tariff element – as necessary for evening out supply.
New solar+storage converter for greater grid stability
Scientists from the Institute of Electrical and Electronics Engineers have presented research suggesting a new topology for residential solar+storage inverters.
Floating PV gains ground in Iberia
