Coöperatie Deltawind

What Coöperatie Deltawind does

Coöperatie Deltawind is a Dutch energy cooperative founded in 1989 and headquartered in Oude-Tonge, Zuid-Holland, on the island of Goeree-Overflakkee. The cooperative develops, owns, and operates renewable energy assets — wind parks (including the co-owned Windpark Piet de Wit II in Ooltgensplaat, developed with Promill B.V.), solar installations, a 20 MWh Energy Opslag Systeem (EOS) battery, research-stage heat networks, and bioenergy facilities — and supplies locally generated electricity to residents of Goeree-Overflakkee via a Lokaal Energiecontract that prioritizes local supply before market sale. The cooperative also issues obligaties (bonds) and windfondsen (wind funds) to enable community investment in renewable projects, and runs complementary services such as Samen Energie Besparen (collective energy savings) and an Energieloket advisory desk.

The business model mixes recurring energy-supply revenue with one-time capital raised through community bonds and wind funds, all distributed through a cooperative governance structure in which members are the collective owners. Deltawind earned the Nationale Houtbouwprijs 2024 for its Energiehuis — a sustainable wooden office building — and in late 2024 signed a cooperation agreement with Energie Coöperatie Regio Rijnmond (ECRR) to extend its local-ownership expertise into the Rotterdam Rijnmond region. With 18 employees and a strictly local membership base, the company describes itself as a community-led energy cooperative rather than a commercial utility, and does not publicly disclose financial metrics.

Partnerships

Two partnerships are on record, tiered core.

• Promill B.V.coreStrategic or Co-development PartnerCo-ownership of Windpark Piet de Wit II in Ooltgensplaat. Both Deltawind and Promill B.V. own the windpark and work together with governments for a future-proof energy system on the island.
• Energie Coöperatie Regio Rijnmond (ECRR)coreStrategic or Co-development PartnerDeltawind provides project managers, expertise, and financial resources to support ECRR in realizing large-scale energy projects in local ownership in the Rotterdam Rijnmond region. The partnership was formalized with signatures from Arnoud Offerhaus (director ECRR) and Monique Sweep (executive board member Deltawind).

Scale indicators1 record

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• Eneco: Major Dutch utility with significant wind and solar generation assets. Operates in the same renewable generation category but at vastly larger scale and corporate (non-cooperative) ownership.
• Vattenfall (Netherlands): Large European utility with onshore wind operations in the Netherlands. Compares as a broad incumbent competing for Dutch wind development pipeline and grid connections.
• Greenchoice: One of the largest Dutch green electricity retailers sourcing from Dutch wind and solar. Broad incumbent in the same renewable supply chain but does not specialize in cooperative/community-owned generation.

Direct peers

• Zeeuwind: Dutch citizen-owned energy cooperative operating wind parks in Zeeland with a comparable member, bond and local-ownership model. Closest direct analogue to Deltawind's cooperative structure and onshore wind focus.
• Coöperatie Zuidenwind: Dutch wind cooperative developing citizen-owned wind projects in the south of the Netherlands. Directly comparable in member-owned wind development and member participation mechanisms.
• Texel Energie: Local energy cooperative on Texel island operating wind, solar and storage with a member-ownership model analogous to Deltawind's island-based community approach.
• Energie Coöperatie Regio Rijnmond (ECRR): Rotterdam-area energy cooperative and Deltawind's signed partner for large-scale local-ownership projects. Comparable cooperative model, but operating in a different (urban-industrial) geography.

Emerging players

• Windunie: Dutch cooperative of wind park owners that provides operational, technical and commercial services to wind cooperatives including Deltawind. Comparable end-customer base (wind cooperatives) but focused on services rather than asset ownership.
• Pure Energie: Dutch green energy supplier developing its own wind and solar projects with a partially cooperative heritage. Compares as a smaller-scale renewable developer competing in similar Dutch wind tenders.

Others

• Energie Samen: Dutch umbrella organization representing local energy cooperatives including Deltawind. Industry association rather than a direct competitor, but closely tied to the cooperative ecosystem in which Deltawind operates.
