Federal energy regulator accused of ‘overreach’ after maintaining provision that forces storage projects to offer minimum prices when competing at state’s capacity market.

“No other policy in play right now” could be “more immediate or more impactful” than a ‘standalone’ Investment Tax Credit (ITC) in the US for energy storage, the CEO of the national Energy Storage Association has said.

The Energy Storage Association (ESA) unveiled a new document this month that offers a number of state policy suggestions designed to spur cost-effective energy storage across the US.

Energy storage companies “have suffered significant and detrimental harm” from changes to rules governing the frequency regulation market in US regional transmission organisation (RTO) PJM Interconnection’s service area, the Energy Storage Association has said.

Energy storage developers have an opportunity to prove the benefits of storage systems compared to fossil fuel technologies in what will be one of the fastest energy storage procurements in history pending in California, according to industry commentators and analysts.
