Alfen providing 20MWh BESS at Dutch wind farm


Netherlands-based BESS integrator Alfen is providing a 20MWh unit for a wind farm in its home market, in the region of Ooltgensplaat.

Alfen has signed an agreement with the Windpark de Plaet plant to install the battery energy storage system (BESS), which the announcement implied will have a power rating of 10MW, i.e. a 2-hour system.

Alfen will provide its TheBattery Elements grid-scale storage product as well as its transformer substation solution, the Diabolo 40H, and the project is expected to be completed in Summer 2024.

The company said its integrated solutions include two identical battery subsystems with a total of 56 battery racks, and the subsystems contain two outdoor transformers and two inverters as well as auxiliary equipment.

The wind plant has been operational since 2021 and has seven turbines totalling 32.4MW of power. It is owned by local firms Promill and Coöperatie Deltawind.

The energy storage market in the Netherlands has been slower than neighbouring Belgium to get off the ground, with a congested grid and ‘double-charging’ of energy storage by treating it as both a consumer and producer of electricity. Grid operator TenneT wants 9GW of new BESS online by 2030 but many in the industry have called for more from the Dutch government to help the country get there.

Most recently, Dutch utility Eneco in June announced a project in Belgium and called for the “…Dutch government to learn from policies in Belgium and Germany so that the Netherlands can actually achieve a climate-neutral electricity supply by 2035”.

This hasn’t stopped Alfen from growing its energy storage activities substantially however, with activities in the Netherlands and abroad helping it grow its storage segment revenues by 500% in the first half of 2023.’ publisher Solar Media will host the 9th annual Energy Storage Summit EU in London, 20-21 February 2024. This year it is moving to a larger venue, bringing together Europe’s leading investors, policymakers, developers, utilities, energy buyers and service providers all in one place.
