NEC Energy Solutions announced that they have completed and commissioned an energy storage system for Germany-based EnspireME, a joint venture between Eneco, a Netherlands-based renewable energy company and Mitsubishi Corp.
The 48 MW energy storage system located in Jardelund, Germany has over 50 MWh of storage capacity and will generate revenue from the primary reserve market by providing reactive power to stabilize the transmission grid.
NEC provided turnkey engineering, procurement and construction services which included its GSS end-to-end grid energy storage solution and its AEROS proprietary energy storage controls software to build the largest energy storage system in Europe. The 48 MW energy storage system built for Germany-based EnspireME, a joint venture between Eneco and Mitsubishi Corp., has over 50 MWh of storage capacity. The system will generate revenue from the primary reserve market by providing reactive power to stabilize the transmission grid.
Transmission system operators (TSOs) in Europe are required to secure a certain number of capacity reserves to prepare for sudden power loss or an extensive blackout. The storage capacity from the system will be sold to the German electricity market through weekly common auctions where European grid operators purchase the reserve capacity they require in the primary reserve control market to guarantee the 50 Hz (Hertz) frequency on the grid. The energy storage system can also take over the role of primary reserve provider and become a more sustainable alternative to coal and gas fired plants.
In addition, Eneco and Mitsubishi Corp. will investigate connecting the battery to local wind farms, providing further value for wind farm owners by storing excess electricity generated during periods of curtailment.
