European Energy has entered into a partnership with Twig, which will serve as the balance responsible party (BRP) for the hybrid renewable energy park in Stouby. Under this agreement, Twig will oversee the balancing of both the existing solar production and the battery energy storage system that will soon be installed at the site. European Energy recently received a building permit to upgrade the current Stouby solar park by adding a large-scale battery energy storage system. The new battery installation will have a power capacity of 28 MW and an energy storage capacity of 112 MWh. With this addition, the solar park will be transformed into a hybrid renewable energy facility that combines power generation with energy storage to improve performance and flexibility.

The existing Stouby solar park has an installed capacity of 88 MW. By integrating a battery storage system, the facility will be able to store surplus electricity generated during periods of high solar production and release it later, especially when electricity demand increases. This enhancement allows for more efficient use of renewable energy and contributes to the stable operation of the broader electricity system. As the BRP, Twig will be responsible for ensuring that the hybrid park meets all grid requirements. This includes managing forecasting, balancing obligations in the electricity market, and coordinating both the production and storage activities to match real-time grid demands. Their role is essential in maintaining a stable flow of electricity and ensuring compliance with market and system regulations.

Jens Peter Zink, Deputy CEO at European Energy, explains that hybrid renewable parks are becoming increasingly important as the energy system evolves. He notes that the collaboration with Twig will help optimise the Stouby facility by allowing electricity to be shifted to periods of peak demand, supporting the grid and helping keep prices lower for consumers during high-consumption hours.

Jonas Stampe, Head of Business Development at Twig, highlights that integrating battery storage adds both operational complexity and financial potential. He states that Twig looks forward to managing and co-optimizing both the solar and battery systems across energy and ancillary markets, working closely with European Energy to maximise the value of the hybrid plant.

Hybrid renewable energy parks that combine solar generation with battery storage are becoming more common across Europe. Such facilities strengthen the power system by improving how renewable energy is utilised and by providing better flexibility in responding to changes in electricity demand. The Stouby hybrid park will continue operating in Randers Municipality, where the existing solar plant is already established and contributing to the region’s renewable energy supply.
