Utility Puget Sound Energy has signed contracts for a solar PV project developed by Qcells and a standalone battery storage project from Brightnight and Cordelio Power in Washington, US.
Sunrun will aggregate home solar-plus-storage systems into a virtual power plant (VPP) capable of providing 5MW of grid support, with California utility Southern California Edison (SCE).
A 3,000MW energy storage target, proposed in Arizona as part of a grid modernisation policy, recognises the role of the technology in reducing the need for fossil fuels to stabilise the grid, a consultant has said.
The Victorian government in Australia has confirmed plans to give a AU$ 0.30/kWh (US$0.23) payment to residential solar system owners that supply electricity to the grid during peak hours.
