Royal Vopak has completed the acquisition of a majority stake in Green Energy Storage (GES) and taken a final investment decision on a 200 MW / 800 MWh battery energy storage project in Oosterhout, the Netherlands.

The total investment in the acquisition and project is around €230 million ($262 million).

The move forms part of Vopak’s strategy to invest in energy transition infrastructure while maintaining a disciplined approach to capital allocation and required portfolio returns.

The company said the investment combines stable contracted revenues with exposure to potential market upside.

The Oosterhout project, one of the largest battery storage developments in the Netherlands, will be connected to the high-voltage grid and is designed to support electricity demand growth, renewable integration and grid balancing.

 It is expected to improve system flexibility and reduce congestion.

Greenchoice will offtake 50 per cent of the project’s capacity under an eight-year tolling agreement.

Construction is set to begin shortly, with commercial operations planned for the first half of 2028.

Through the acquisition, Vopak gains a development pipeline and asset management platform in battery storage.

The company said its infrastructure expertise and financial strength will help scale the business.

As of July 1, 2026, Vopak holds a 79 per cent controlling stake in GES and plans to acquire the remaining shares within two years.

GES will be fully consolidated in Vopak’s accounts from July 2026.

“Completing this acquisition and taking the investment decision on the Oosterhout project moves us from intention to delivery. Together with the GES team, we are building one of the leading battery storage platforms in the Netherlands and supporting a reliable and sustainable energy system.” said Maarten Smeets, Executive Vice President Global Business Development at Vopak.

“Today's milestone reflects years of work by the GES team in developing a high-quality battery storage platform. With Vopak, we can now realise the 200 MW / 800 MWh while accelerating the development of the rest of our pipeline. Together, we are creating the flexibility needed for a secure, reliable and resilient Dutch electricity system.” said Guus Bengsch, CEO GES. 

"Battery energy storage is becoming an essential building block of tomorrow’s energy system. We are proud to continue our collaboration with GES and Vopak. This project marks an important milestone and enables us to contribute to greater flexibility in the Dutch electricity system while helping reduce grid congestion." said Erik van Engelen, CEO of Greenchoice. -OGN/TradeArabia News Service
