Swedish company Flower enters Finnish market. 30 MW battery energy storage system begins trading

Swedish energy technology company Flower has announced the full launch of its operations in Finland. The key element of its expansion is the start of trading operations for a large-scale battery energy storage system with a power capacity of 30 MW and an energy capacity of 30 MWh, located in Kaunola. The facility has been connected to the balancing, day-ahead and intraday markets.

New asset in Enordic Evergreen’s portfolio

The energy storage project was developed by independent power producer Enordic Evergreen. The facility in Kaunola, located near Riihimäki in southern Finland, is considered one of the largest installations of its kind in the country.

The project began commercial operations in March 2026, but its full market integration required additional time. Prequalification procedures and integration testing were carried out over the following months, and in July, Flower signed its first agreement to optimize the asset.

The facility is now the second operational energy storage system owned by Enordic Evergreen and the Clean Energy Evergreen Fund (managed by Ardian) in the Nordic region.

Taking on the BRP role and further expansion plans

Entering the Finnish market marks another step in the development of Flower’s business model. The company had already been active in Finland since 2025, but until now, its operations had focused exclusively on providing trading services without directly managing assets as a balance responsible party (BRP).

The Kaunola project enables the company to offer comprehensive algorithmic optimization for large-scale battery energy storage systems. The Swedish developer has announced that the next stage of its European expansion will focus on Germany, where it plans to introduce similar battery optimization and energy trading services.
