PowerField, a Dutch energy company, has begun delivering fully automated Frequency Containment Reserve (FCR) services after being officially registered as a Balancing Service Provider (BSP) by TenneT, the transmission system operator responsible for electricity supply in the Netherlands and parts of Germany.
The FCR service is designed to maintain the electricity grid frequency around 50 Hz, with PowerField’s battery energy storage systems (BESS) now able to automatically respond within a second to sudden frequency changes by either storing electricity or feeding it back into the grid. Previously managed manually, the FCR bidding process is now fully automated using an in-house algorithm developed in collaboration with FlexPower. The system calculates available capacity, determines bid prices, and completes daily bids independently.
Eelco Rondhuis, Head of Energy Management at PowerField, said: “The first automated bids have now been successfully completed, making FCR a fully embedded part of our operations. This enables us to continuously create value from solar energy while strengthening our long-term contribution to grid stability. Thanks to our collaboration with FlexPower, we have been able to implement a scalable and integrated solution.”
Amani Joas, Managing Director at FlexPower, added: “Our collaboration with PowerField demonstrates how technology and sustainability reinforce each other. With a fully integrated approach, we can maximise the flexibility of combined generation and storage locations.”
The automated FCR control is part of PowerField’s broader strategy of integrating solar generation, storage, and trading on a single platform to improve operational coordination and flexibility. In 2024, the company commissioned a 52 MWh BESS at Solar Park Wanneperveen, the Netherlands’ largest project fully integrating solar energy and storage. The combined system allows PowerField to deploy solar power precisely in response to real-time electricity demand.
