May 30, 2019: Three companies — renewables management firm Enel Green Power Germany (a subsidiary of Enel), renewable energy company Enertrag and energy storage company Leclanché — have inaugurated a 22MW lithium ion energy storage system in Cremzow, Germany, the companies announced on May 16.
The project is owned by EGP Germany (90% share holding), with the remainder owned by Enertrag. Swiss firm Leclanché will be the project’s storage supplier.
The €17 million ($16 million) ESS will deliver primary control energy services to help stabilize the German power grid in real time within 30 seconds.
The integration of the system into Enertrag’s wind power production is also being studied to determine how excess wind energy can be stored in the battery system to avoid curtailment.
Jörg Müller, CEO of Enertrag, said the project would allow grid operators to restart the systems in the event of a supply failure.
The German primary control market now has more than 600MW of capacity, up from 200MW in 2017.
