Wärtsilä to Set Up Netherlands’ Largest Energy Storage System

Technology group Wärtsilä will supply a 25-megawatt (MW) / 48-megawatt hour (MWh) 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, an 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 is expected to store the equivalent of the annual energy consumption of more than 9,000 households each year.

“The Buffalo battery will help stabilise the Netherlands’ electricity grid and save a maximum of 23,000 tons of carbon dioxide emissions per year,” said Maarten Quist, COO, GIGA Storage. “We’re pleased to work with Wärtsilä to implement this landmark project, which will help us reach our goal of deploying 1.5 GW of energy storage in Europe by 2025.”

The Dutch government has set a goal to reduce greenhouse gas emissions by 49% by 2030 and a 95% reduction by 2050. The growth of renewable energy in the Netherlands and likewise across Europe has helped to decarbonise the energy system but has also created congestion on electrical networks, making energy storage a necessity for reliability. Recent reports indicate that the Netherlands will need between 29 and 54-gigawatts (GW) of energy storage capacity by 2050.

“Wärtsilä sees a major opportunity and paramount need to help our customers increase energy storage deployment throughout Europe in order to realise a 100% renewable energy future,” said Pekka Tolonen, Director, Europe, Wärtsilä Energy. “This is an important milestone for Wärtsilä as our first project in the Netherlands. We’re thrilled to add yet another country to our 4 GWh portfolio of market-leading energy storage technology deployments worldwide.”
