The Äänekoski facility will feature a power output of 30MW and a capacity of 60MWh, while the Laukaa site will offer 45MW of output and 90MWh of capacity.
Construction on both facilities is scheduled to begin in spring 2026, with completion expected in around a year.
The two projects aim to enhance grid stability and help manage the integration of renewable electricity sources in Finland.
Battery storage systems are increasingly used to address fluctuations in electricity production and demand, contributing to the consistent operation of national electricity supply.
Winda Energy CEO Tuomas Hooli said: “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.”
Winda Energy is responsible for developing and designing both facilities, while Wood & Co provides financing.
Wood & Co Renewables sub-fund investment director Robert Doucha said: “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. Local expertise on the part of our partners is essential for the successful delivery of these projects.”
Winda Energy, established in 2011, operates across Finland developing wind, solar and energy storage projects from planning to delivery.
