German wind turbine maker Nordex SE announced on Friday the inauguration of a 720-kW/792-kWh lithium-ion battery storage facility at the site of the Curslack wind farm in Bergedorf, Hamburg.
The energy storage plant consists of 24 batteries, the same as the ones used in electric vehicles (EVs) and based on the latest BMW technology. It was built by Swedish state-owned utility Vattenfall AB in cooperation with Nordex and the Competence Center for Renewable Energies and Energy Efficiency (CC4E) of the Hamburg University of Applied Sciences (HAW). The system makes it possible to avoid shutting down the five Nordex wind turbines at the site in the event of a grid overload.
The battery storage plant is one of 25 demonstrators that will be built as part of the NEW 4.0 (Norddeutsche EnergieWende) project, which is expected to help the Northern German states of Hamburg and Schleswig-Holstein end up with 100% renewable power by 2035. The NEW 4.0 project is funded by the German Federal Ministry of Economics and Energy (BMWi).
Vattenfall, Nordex and CC4E will be jointly designing models for innovative system services and also developing and testing control algorithms and parameters to enable renewable energy providers to offer these, together with battery storage systems, Nordex’s statement says.
