The Texas Waves energy storage projects will see E.ON construct two batteries with a total storage volume of nearly 20 MW. They will be located at E.ON’s existing wind parks in Pyron and Inadale in the west of the state.
Both projects are expected to be operational by the end of this year, when they will each provide 9.9 MW of energy to the grid.
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. The lithium-ion battery systems connected to the grid will be an integral component of the E.ON wind parks near Roscoe and will be charged by the wind turbines there.
For the Texas Wave projects, E.ON is collaborating with Virginia-based Greensmith Energy, a provider of energy storage software and services in which E.ON has invested since 2015.
Greensmith is also a partner in Iron Horse, E.ON’s first grid-connected battery project located southeast of Tucson, Arizona. This 10 MW energy storage system, which includes a neighbouring 2 MW solar plant, will come online in the first half of this year.
