Finland

Kapuli in Mäntsälä is part of an emerging storage cluster in southern Finland. With a capacity of 20 MW, the project contributes significantly to the flexibility of the regional grid. The bundling of several plants creates operational synergies, reduced operating costs, and optimized market integration. The location near important grid and transport hubs underscores the strategic nature of the project: Kapuli is not just a single plant, but a building block of a scalable platform in the Nordic energy market.
