Energy figures

Eneco generates energy from a variety of sources, ranging from onshore and offshore wind to solar, biomass and combined heat and power. On this page, you will find an overview of our generation capacity (MW) and the actual energy generated (GWh) by energy source, so you can see exactly where our energy comes from and how our portfolio is developing.

Period covered: 1 April 2025 in comparison with 31 March 2026.

1. Owned energy capacity represents the amount of operational heat and electricity capacity (MW) from assets that are fully or partially owned by Eneco. Capacity is included proportionally to Eneco's legal ownership share in those assets. Contracted electricity capacity represents the amount of technically operational capacity (MW) from external assets where Eneco has contractually secured the output through Power Purchase Agreements (PPAs). Total managed capacity is the sum of owned and contracted capacity. Only capacity that is technically operational at year-end is included in these numbers.

1. Owned energy production represents the amount of heat and electricity (GWh) generated during the reporting year by assets that are fully or partially owned by Eneco. Production volumes are included proportionally to Eneco's legal ownership share in those assets. Contracted electricity production represents the amount of electricity (GWh) generated during the reporting year by external assets where Eneco has contractually secured the output through Power Purchase Agreements (PPAs). Total managed electricity production is the combined volume of owned and contracted production.
