Royal Vopak, Vattenfall agree on 400 MWh tolling deal for Dutch battery project

Swedish energy company Vattenfall has signed a tolling agreement with Dutch energy infrastructure company Royal Vopak for a portion of a planned 150 MW / 600 MWh battery energy storage system (BESS) near Meeden, in Groningen province, the Netherlands.

Under the agreement, Vattenfall will secure access to 100 MW / 400 MWh of capacity, equivalent to two-thirds of the planned project’s total capacity, with the BESS expected to enter commercial operation in Q2 2028.

“Battery storage helps make better use of renewable electricity and contributes to a more reliable and efficient energy system. We are pleased to partner with Vopak and support the development of large-scale energy storage in the Netherlands,” said Erik Suichies, head of wholesale energy at Vattenfall.

According to Vattenfall, the latest tolling agreement supports the company’s target of contracting at least 1.5 GW of battery capacity across its core markets.

Royal Vopak is traditionally known as a tank storage company, operating terminals for oil products, chemicals and gases. Energy storage is now a key growth area that Royal Vopak is targeting, according to Jarno Veldhoven, vice president of business development battery energy storage solutions.

“As renewables represent an increasing share in the energy mix, we see a growing demand for battery energy storage solutions. With our aim to provide reliable and affordable battery systems to our customers we are excited to have Vattenfall as a long-term partner,” said Veldhoven.

In July 2026, Royal Vopak acquired a 79% controlling stake in Dutch BESS developer Green Energy Storage (GES), including its planned 200 MW / 800 MWh Sequoia project in Oosterhout, which is expected to enter commercial operation in the first half of 2028. The remaining 21% stake will be acquired no later than July 1, 2028.
