The North American subsidiary of international investor-owned energy supplier E.ON has partnered with Greensmith Energy to deliver two grid-scale energy storage systems known as the Texas Waves projects.

The projects will be 9.9MW each, featuring short duration lithium-ion batteries, and will be used to provide ancillary services to the Electric Reliability Council of Texas (ERCOT) via load shifting and increasing system reliability and efficiency. Greensmith will be lending its GEMS software platform for the projects; the most widely deployed software solution in the market today.

The projects will be co-located at the existing E.ON Pyron and Inadale wind farms in Texas and are expected to come online by the end of this year. They will be the second and third grid connected lithium-ion battery systems installed by E.ON in North America, following the 10MW Iron Horse project in Arizona.

“The battery energy storage systems will be an integral part of the wind farm facilities near Roscoe, Texas, and will be charged from the wind farm,” said Mark Frigo, vice president of Energy Storage North America at E.ON. “These projects will benefit from the lessons learned and experience accumulated on our Iron Horse project, which is currently under construction.”

“Our partnership with industry leaders like E.ON to support growing energy storage opportunities across multiple applications and regions, reflects why we continue to work so hard to build and deliver the most advanced energy storage systems and software available today,” said John Jung, president and CEO of Greensmith Energy. “With over 3GW of solar and wind generation already installed in the U.S., E.ON is committed to transforming our 20th century electric grid, so naturally, we are honoured to be a part of that technology vision.”
