Winda Energy has announced plans to develop two industrial-scale battery energy storage projects in central Finland, in partnership with investment group Wood & Co, as part of efforts to strengthen grid stability and support renewable energy integration.
Äänekoski and Laukaa will be home to the two facilities, which will have a total storage capacity of 150 MWh. The Äänekoski project will be able to produce 30 MW of power and store 60 MWh of energy. The Laukaa site will be able to produce 45 MW of power and store 90 MWh of energy.
Construction timeline and project scope
Construction of both projects is scheduled to begin in spring 2026, with completion expected within approximately one year. Full commercial operations are planned for the second quarter of 2027.
The projects are meant to make the grid more reliable and make it easier to use renewable energy sources, especially since Finland is still adding more wind and solar power.
Role of battery storage in energy systems
Battery energy storage systems are very important for keeping the power supply stable and consistent by managing changes in electricity generation and demand. As more renewable energy sources come online, these systems are being used more and more to support modern electricity grids.
Leadership insights on the project
Commenting on the development, Tuomas Hooli, CEO of Winda Energy, 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 will be responsible for the development and design of the facilities for the battery storage project, while Wood & Co will provide financing support.
Robert Doucha, Investment Director at Wood & Co Renewables sub-fund, added,
“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.”
