Dutch energy group Eneco has announced the appointment of Martijn Hagens as Chief Executive Officer, effective from 1 March 2026. The decision was confirmed by the company’s Supervisory Board. Kees Jan Rameau will remain in the interim position until Hagens officially assumes the role.

A profile shaped by Vattenfall

Currently Senior Vice-President and Head of the Markets business area at Vattenfall, Martijn Hagens also serves as CEO of Vattenfall NV, the Dutch subsidiary of the Swedish group. His background includes several executive roles within Vattenfall and its former affiliate NUON, active in the Dutch energy market.

Mel Kroon, Chair of Eneco’s Supervisory Board, stated that the appointment is based on “Martijn’s ability to create value and drive Eneco’s growth strategy”. According to him, bringing in an experienced leader from the energy sector will strengthen the company’s current trajectory.

Management transition planned in advance

The leadership transition comes as Eneco continues its internal restructuring. No further details were provided on the length of the interim period under Kees Jan Rameau, nor the reasons for announcing the appointment seven months in advance.

Holding a degree in Industrial Engineering and Management Science from Eindhoven University of Technology, Martijn Hagens confirmed his commitment in a statement issued by the company. He expressed his intention to “work with Eneco teams to ensure reliable energy for customers”.

A shift amid sector transformation

Eneco, which operates in the energy markets of the Netherlands, Belgium and Germany, has been jointly owned since 2020 by Mitsubishi Corporation and Chubu Electric Power Co Inc. through a joint venture. Hagens’ appointment may signal a strategic repositioning, as the European electricity market continues to evolve.

The company has not disclosed whether additional governance changes are expected before the new CEO assumes office.
