E.ON is planning to construct two lithium–ion battery facilities totalling 20 MW in Texas. The Texas Waves energy storage projects will be located at and connected to E.ON’s existing wind parks in Pyron and Inadale in the west of the state, to be in operation by the end of 2017.
The batteries will provide system services for the Electric Reliability Council of Texas (ERCOT) market, balance out fluctuations across the grid, and improve supply security.
For the Texas Wave projects, E.ON is collaborating with Virginia-based energy storage software and services provider Greensmith Energy, in which E.ON has been an investor since 2015. Greensmith is also a partner in E.ON’s 10 MW Iron Horse grid- connected battery project, located south east of Tucson, Arizona. This 10 MW energy storage system, which is integrated with a neighbouring 2 MW solar plant, is due to come online in the first half of 2017.
