Potential developers for a 500MW pumped hydropower energy storage facility at a reservoir in San Diego have until mid-September to respond to a request for proposals (RfP).
Market conditions are “artificially” restricting energy storage batteries from “leveraging and maximising their multiple capabilities” a US trade group which includes utilities, technology and service providers and grid operators among its membership has argued.
Louisville Gas and Electric and Kentucky Utilities (LG&E and KU), arms of US firm PPL Corporation, have developed a research centre for energy storage at a power plant in Kentucky.
Austin Energy, a publicly-owned electric utility in Texas, is delivering megawatt-scale storage systems as part of the US Department of Energy’s Sustainable and Holistic Integration of Energy Storage and Solar PV (SHINES) project.
Arizona utility Tucson Electric Power (TEP) claims that the cost-effectiveness of a new large-scale solar-plus-storage facility under construction will allow it to provide “more solar energy to more customers for less money”.
