Sustainable energy for the future

Primco was created after the investment company Momentum Capital took over the company Parenco Hout. This company is the link between forest owners, forest managers and the wood industry and also supplies prunings and wood waste for power plants. The participations decided to connect their know-how and the idea for the Primco power plant in Lelystad was born.

By converting organic waste streams into useful energy, we, as the developer, investor, and operator of sustainable power plants, offer opportunities for society to become less and less dependent on fossil fuels.

Parenco Hout also supplies its sister company CEG with raw materials for its activities. Primco has power stations in Lelystad (The Netherlands), Duiven (The Netherlands) and Ellesmere Port (United Kingdom).
