Royal Vopak agreed in principle in May 2026 to acquire a majority stake in Green Energy Storage, a Dutch BESS developer based in Breda. The deal value was not disclosed. GES is developing large-scale storage projects in the Netherlands, including the 200 MW / 800 MWh Oosterhout battery project. The transaction remains subject to FID and customary approvals.

The shift is clear: Netherlands BESS M&A is moving from asset-by-asset trades toward platform control. Vopak is not buying one operational battery. It is taking majority ownership of a developer with a project pipeline, permitting capability, and lifecycle control from site identification to operations.

This follows a wider European pattern. Enerdatics tracked a 120% Y/Y surge in European BESS transactions in Q3 2025, with around 18 GW traded across 22 deals, led by demand for grid-connected and late-stage storage assets.  Similar buyer selectivity is visible in [Europe BESS M&A insights].

Vopak is a listed infrastructure buyer. Its commercial reason is infrastructure adjacency: storage fits its shift into energy transition infrastructure while adding exposure to Dutch grid-balancing revenues.

GES brings the development engine. Its Oosterhout project is advanced-stage but pre-FID, giving Vopak control before construction capital is committed.
