EON breaks ground on windfarm energy storage projects

E.ON has started construction on two energy storage projects in the US.

The projects are located on the sites of two existing E.ON windfarms in Texas – Pyron and Inadale.

The Texas Waves scheme consists of two 9.9 MW short-duration energy storage projects using lithium-ion battery technology and E.On said it will be “an integral part of the wind farm facilities” near Roscoe.

These 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 this year.EON breaks ground on windfarm energy storage projects

“Breaking ground on this project is particularly exciting as it allows us to continue to build our reputation as one of the leading players in North American energy storage,” said Mark Frigo, vice-presdient of Energy Storage North America at E.ON.

“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, Arizona, is online already and E.On said it is helping Tucson Electric Power “maintain reliable electric service for more than 400,000 customers by providing frequency regulation and voltage control support”.

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, increasing system reliability and efficiency.

E.ON chose Greensmith Energy for energy storage software and services and has Primoris Renewable Energy for engineering, procurement and construction on the projects.
