A solar-plus-storage project in New York which has just been completed is the first community project of its type and should help lower electricity costs for participants by 10% for the next 25 years.

Consumers in a South London housing estate will soon be able to trade solar power amongst themselves as an blockchain-enabled pilot project backed by EDF gets underway.

Following news yesterday of the first grid-scale solar-plus-storage system on the Hawaiian island of Molokai, two more modestly-sized projects show the potential diversity of applications for energy storage in the US state.

The addition of energy storage has made a 1MW community rooftop solar project in Massachusetts viable, after a long-term PPA was secured with a local utility.
