E.ON Gets To Work On Energy Storage At Texas Wind Farms


E.ON has begun construction on its Texas Waves energy storage projects, which are co-located at the company’s existing Pyron and Inadale wind farms in west Texas.

Texas Waves consists of two 9.9 MW, short-duration energy storage projects using lithium-ion battery technology. According to E.ON, they will be an integral part of the wind facilities near Roscoe, Texas, and are expected to be online by the end of this year.

The projects will be the second and third grid-connected, lithium-ion battery systems installed by E.ON in North America.

Mark Frigo, vice president of energy storage for North America at E.ON, says, “These projects will benefit from the lessons learned and experience accumulated on our Iron Horse project, completed back in April.”

Iron Horse, E.ON’s first grid-connected lithium battery system project, consisting of a 10 MW energy storage facility with an adjacent 2 MW solar array southeast of Tucson, Ariz., is helping Tucson Electric Power maintain reliable electric service for more than 400,000 customers by providing frequency regulation and voltage control support.

On the other hand, the Texas Waves projects are designed to provide ancillary services to the Electric Reliability Council of Texas market and will be capable of responding to shifts in power demand more quickly, thereby increasing system reliability and efficiency.

E.ON designated Greensmith Energy for energy storage software and services and selected Primoris Renewable Energy for engineering, procurement and construction on the Texas Waves projects.
