EDF power solutions wins decentralised Grid Booster project of the flexibility tender by Amprion GmbH, a German electricity transmission system operator. With a total capacity of 250 MW spread across 5 sites, this battery storage system will support the transport of electricity from the north to the south and will alleviate grid imbalances and congestion. This innovative project aligns with the overall ambitions of EDF power solutions to integrate new low- carbon production assets into the electrical system and enhance grid performance.

The Grid Booster project combines 5 batteries, with a capacity of 50 MW each, making it one of the largest storage systems in Germany. The batteries will be installed at key nodes to optimize electricity flow. The sites were chosen to make the grid booster usable for the distribution network operator LVN as well, thereby increasing the economic benefits of this system. The grid booster is used to increase the utilisation of existing power lines, allowing more electricity to be transported from wind and solar parks in the north to the south. With the project, Amprion also introduces a unique selling point in Germany: when the Grid Booster is not needed to stabilise the transmission grid, it can be used to relieve the regional power grid.

The Grid Booster project offers high availability and ensures an effective response to grid imbalances. By improving the grid performance, the Grid Booster will also enable Amprion to reduce redispatch measures – which has a positive impact on grid fees for customers. 

Under the decentralised Grid Booster model, the storage system will be managed by Amprion during the winter months. During the summer months, the batteries can be offered by EDF power solutions on the German market and provide services to the electrical system – also an innovation in the relationship between market players and network operators. EDF power solutions will remain responsible for the operation, and the maintenance of the batteries throughout their lifespan.

Battery development is currently experiencing significant growth in Germany, particularly to support the integration of renewable energy sources to reduce the carbon footprint. As a global leader in battery storage systems with over 800 MW in operation and 1.2 GW under construction, EDF power solutions leverages its expertise to drive the energy transition and improve grid performance, positioning itself as a major player in Germany's energy storage sector.
