The technology group Wärtsilä will supply a 25-megawatt energy storage system to GIGA Storage BV in the Netherlands to help stabilise the electric grid. This will be Wärtsilä’s first energy storage project in the Netherlands and it will be the country’s largest system to date. The order was booked to Wärtsilä order intake in December 2021, and the system is expected to become operational in October 2022.The Wärtsilä energy storage system, called the GIGA Buffalo battery, will be co-located with wind and solar assets at the Widnet smart grid, located at the Wageningen University & Research test centre in Lelystad. Eneco, a leading energy provider in the Netherlands, will utilise the battery to make its energy services more sustainable and add more renewable energy on the grid. The energy storage will also help to optimise the power system, regulate energy frequency and reliability on the grid and improve revenues. As the largest energy storage project in the Netherlands to date, it will store the equivalent of the annual energy consumption of more than 9,000 households each year.
