Last Thursday, Oct. 24, 2024, the new Energy Storage System (EOS) at the Piet de Wit II Wind Farm on Goeree-Overflakkee in the Netherlands was commissioned.
The EOS was symbolically activated by Jaap Willem Eijkenduijn, alderman for sustainability of the municipality of Goeree-Overflakkee, together with David Mol and Monique Sweep, directors of the 32.4 MW wind farm which is owned by Promill B.V. and Coöperatie Deltawind. Both parties, together with local governments, are committed to a future-proof energy system on the island.
Contributing to a balanced energy system
It concerns a 20MWh TheBattery Elements EOS by Alfen, consisting of 2 identical battery subsystems with a total of 56 battery racks. The subsystems include 2 outdoor transformers and 2 inverters, as well as a variety of auxiliary equipment. The system can charge in 2 hours and return to the grid at a later time. The EOS can as such help solve several current challenges in the energy system.
Demand and supply of energy must be balanced for the power grid to function properly. When this doesn’t work properly it affects energy prices. At times when more renewable electricity is produced than consumed, the surplus is “thrown away” due to the lack of space to transmit it through the existing power grid. For a successful energy transition, generated renewable energy must be better and fully utilized. An EOS can contribute to that.
