Olana Energy Oy has made a final investment decision (FID) for an energy storage project in Koski Tl, located in the municipality of Koski Tl, Finland.

The 7 MW / 8 MWh battery energy storage system (BESS) will be connected to the Caruna DSO grid, with commercial operation (COD) expected in mid-2026. The project further strengthens Olana’s presence in Finland and supports the company’s growing portfolio of grid-connected storage assets.
