E.ON North America has announced that it construct its Texas Waves energy storage projects at the existing E.ON Pyron and Inadale wind farm in West Texas.
Texas Waves consists of two 9.9 megawatt (MW) short duration energy storage projects using lithium-ion battery technology.
The Texas Waves 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.
E.ON Solar & Energy Storage president Steve Trenholm said: "Our Texas Waves projects allow us to break new ground and establish ourselves in the storage business in the Texas market, complementing our more than 2.7GW of operating wind capacity in the state."
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.
E.ON Energy Storage North America vice president Mark Frigo said: "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.
"These projects will benefit from the lessons learned and experience accumulated on our Iron Horse project, which is currently under construction."
Iron Horse, E.ON's first grid connected lithium battery system project, is a 10 MW energy storage facility with an adjacent 2 MW solar array southeast of Tucson, Ariz., and is expected to be in operation in the first half of 2017.
E.ON will be partnering with Greensmith Energy, the leading provider of energy storage software and services, for the Texas Waves projects.
Greensmith Energy president and CEO John Jung said: "As the leader in energy storage software and solutions – Greensmith is proud to partner with E.ON, a true visionary in power, to deploy two additional grid-scale systems towards the growth of the Texas storage market.
"We couldn't be more thrilled to support E.ON with our grid-scale experience and technology to enable a more intelligent and resilient grid in Texas and abroad."
E.ON has developed, built, and operates more than 3 GW of solar and wind renewable energy generation across the US, with more on the way. E.ON also offers O&M and asset management services to third party owner/operators looking for 'Service with an Owner's Eye.'
