Nevada utility NV Energy and Google are plotting a major solar-plus-storage facility outside of Las Vegas in a deal being billed as the largest battery-backed solar corporate agreement in the world.

Los Angeles Department of Water and Power (LADWP) last week approved power purchase agreements for what is thought to be the cheapest solar-plus-storage project so far in the US.

Assets are up for sale following the bankruptcy of EnSync, a networked smart home solutions provider from the US which has been using battery energy storage to aggregate connected systems for energy trading and other services.

A proposal by Pacific Gas & Electric (PG&E), one of California’s three main investor-owned utilities (IOUs) to deploy large-scale energy storage to replace peaking natural gas plants has been approved by the state’s regulator.
