EEW Holding, EWE-Verband, New Energy and Industrial Technology Development Organization, NGK Insulators and Showa Denko Materials have delivered the battery energy storage project.

Additional information

Total budget: Approximately 2.88 billion yen.
The project aims to demonstrate the effectiveness of the large-scale hybrid power storage system designed by taking advantage of the features of lithium-ion batteries (capacity: 7.5 MW/2.5 MWh) with a high-power charge/discharge output and durable, large capacity NAS batteries (capacity of 4 MW/20 MWh), in combination with Hitachi Power Solutions’ power grid information and battery control system that controls both batteries and enables the following functions by communicating information for the electricity trading.
