E.ON North America announced that it would develop two 9.9 megawatt (MW) short duration energy storage projects using lithium-ion battery technology at its existing E.ON Pyron and Inadale wind farms in West Texas.
The projects will be the second and third grid connected lithium-ion battery systems installed by E.ON in North America and are expected to be online by the end of 2017.
The projects are designed to provide ancillary services to the Electric Reliability Council of Texas (ERCOT) market and will be capable of responding to shifts in power demand more quickly, increasing system reliability and efficiency, the company said
