Winda Energy Oy is to build two battery storage facilities with a combined capacity of 150MWh in Äänekoski and Laukaa in central Finland.
The company said the projects are being developed in cooperation with investment group Wood & Co and will support grid stability and renewable integration.
Winda added that the Äänekoski project will have a capacity of 60MWh and 30MW output, while Laukaa will deliver 90MWh and 45MW.
Construction on both sites is set to begin in spring 2026 with completion expected after around one year.
The company said the projects are financed by Wood & Co and target full commercial operations in the second quarter of 2027.
“Battery storage is the backbone of a reliable renewable energy system. With Äänekoski and Laukaa, we are delivering exactly the kind of flexible capacity Finland needs as the share of wind and solar in the grid continues to grow,” said Tuomas Hooli, chief executive of Winda Energy.
“We invest in projects that are currently at the ‘ready-to-build’ stage. The start of full commercial operations is planned for the second quarter of 2027,” said Robert Doucha, investment director of the WOOD & Co. Renewables sub-fund.
