E.on installing batteries at Texas wind farms

Sep 6 (Renewables Now) – German utility E.on SE (ETR:EOAN) said Tuesday it has started building 18.8 MW of energy storage capacity at its existing 249-MW Pyron and 197-MW Inadale wind farms in Texas.

The Texas Waves system will consist of two 9.9-MW short duration energy storage facilities using lithium-ion batteries and will operate together with the two wind farms near Roscoe city in West Texas. The two facilities are expected to become operational by the end of this year, providing ancillary services to the Electric Reliability Council of Texas (ERCOT) market.

US firm Greensmith Energy was contracted to take care of the energy storage software, while Primoris Renewable Energy is in charge of engineering, procurement and construction (EPC).

E.on North America in June opened its Iron Horse energy storage and solar project, a 10-MW/2.5-MWh storage facility and an accompanying 2-MW solar array, in Arizona, which was its first energy storage project in North America. The German firm has developed, built and operates over 3,100 MW of solar and wind parks in the US.
