Multinational utility and independent power producer (IPP) RWE has started building its first battery energy storage system (BESS) project in the Netherlands.

The Germany-headquartered company announced the start of construction on the BESS at its Eemshaven biomass and gas power plant complex, near Groningen, last week (8 February).

First announced in September last year, the project will have a power capacity of 35MW and an energy storage capacity of 41MWh. RWE said it will be virtually coupled with other plants in the Netherlands including the 800MW OranjeWind offshore wind energy project, which it is developing.

At the time of the announcement, the company said it would be investing €25 million (US$27 million) into the project. It is the company’s first BESS in the Netherlands, while in Germany it has been one of the most active developer-operators, with two of the largest systems in the country under construction.
