After the expansion of the biggest battery project in world, milestones have been recorded for three more major solar-plus-storage and standalone battery storage projects in California, Hawaii and Florida.
Approval has been granted — with significant conditions attached — for a large-scale standalone battery storage project designed to help the Hawaiian island of Oahu overcome energy reliability and supply concerns as a coal power plant retires.
As society moves away from centralised fossil fuel generators to increasing shares of distributed renewable energy resources, the idea that customers’ homes could become host to virtual power plants (VPPs), joining the dots between electricity supply and demand across the grid, has gradually gathered traction. Andy Colthorpe speaks with Suleman Khan CEO of Swell Energy, which has raised nearly half a billion dollars in financing for solar-plus-storage VPPs in 14,000 homes across California, New York and Hawaii.
There has been growing uptake in battery energy storage in Midwestern US states that have traditionally depended on burning coal for electricity, with some “very big projects planned,” an analyst has said.
Energy company Total and solar-plus-storage developer 174 Global, a division of Hanwha Group, have formed a joint venture to develop utility-scale solar and storage projects with a total capacity of 1.6GW in the US.
A large-scale solar PV system paired with pumped hydro energy storage could cover as much as 25% of the Hawaiian island of Kaua’i’s energy demand, pushing the island’s total share of renewables in its energy mix past 80%.
