E.ON has started construction work on its Texas Waves power storage project in the USA, which is due to be taken into operation by the end of 2017.

The 20 MW of storage (2 x 2.5 MWh) is being built on the sites of existing E.ON wind farms, Pyron and Inadale in West Texas. As an integral part of the wind farms, Texas Waves will be able to react quickly for the network operator, Electric Reliability Council of Texas (ERCOT) to cope with changes in energy requirements and thereby increase both the reliability and efficiency of the system.

With both the industrial-scale 10 MW plants, E.ON is expanding its role as an important player in the North American power storage market. These are the second and third largest network connected lithium ion battery systems that E.ON has installed in the USA to date.

E.ON’s first storage project, Iron Horse, consists of a 10 MW battery and an associated 2 MW solar power plant south east of Tucson, Arizona. The system has already been commissioned, and helps support the power supplier – Tucson Electric Power – with frequency and voltage control.
