May 07, 2026 [Storage Terminals Magazine]- Royal Vopak has reached an agreement in principle to acquire a majority stake in Green Energy Storage, in a move aimed at accelerating the development of large-scale battery energy storage systems (BESS) in the Netherlands.
GES, a Dutch battery storage developer based in Breda, has established a strong presence in the Dutch energy market through the development of utility-scale storage projects. The company oversees the entire project lifecycle, including site identification, permitting, construction and operational management, while also supporting efforts to reduce grid congestion and improve flexibility within the energy system.
Under the proposed transaction, Vopak will acquire a majority equity interest in GES and support the continued expansion of the company’s project portfolio. This includes the large-scale battery storage project in Oosterhout, which is planned to deliver 200 MW / 800 MWh of storage capacity. The project is expected to play a significant role in balancing the Dutch electricity grid and alleviating congestion.
Maarten Smeets, executive vice president global business development at Vopak, said the acquisition represents a strategic step into energy transition infrastructure through battery storage and noted that the combined expertise and project pipelines of both companies position them to accelerate the deployment of large-scale storage solutions.
GES CEO Guus Bengsch said the partnership with Vopak would help speed up the realisation of the company’s pipeline, enabling it to scale operations more rapidly and contribute more effectively to easing grid congestion and supporting the energy transition in the Netherlands.
The transaction remains subject to a Final Investment Decision, as well as customary approvals and conditions. Vopak said details of the investment value will be disclosed following completion of the transaction and a positive FID.
