A pumped hydro energy storage (PHES) project at a former gold mine in Queensland, Australia which would be able to store 250MW of power for up to eight hours has raised significant funding in the past few days.
Distributed renewables and energy storage are now the cheapest form of baseload power and if Western Australia’s remote areas can benefit from that, we can all benefit, argues David Martin, founder of energy trading platform provider Power Ledger.
Once again, lithium-ion battery-based solutions have been selected for projects that will “improve overall reliability” of electricity supplies, to enhance the grid and make it more efficient, while also providing backup in case of outages.
A large-scale battery storage system will be built in Texas for the US’ biggest electric utility cooperative, to time-shift solar-generated loads and provide grid services to transmission operator ERCOT.
Southern California Edison, one of the US’ top-ranking utilities for energy storage capacity already deployed, has signed contracts for seven more projects, totalling 195MW in its California service area.
