On 16 October 2025, the Commission received notification of a proposed concentration pursuant to Article 4 of Council Regulation (EC) No 139/2004 (1).
This notification concerns the following undertakings:

Rotterdam Shore Power B.V. (‘RSP’, the Netherlands).




Eneco and MHR will acquire within the meaning of Article 3(1)(b) and 3(4) of the Merger Regulation joint control of RSP.
The concentration is accomplished by way of purchase of shares in a newly created company constituting a joint venture.

MHR is a wholly-owned subsidiary of HBR, which is the port authority in Rotterdam. HBR, including through MHR, manages, operates and develops the port area of Rotterdam.
