Nakkila Works Oy has been selected as the supplier for a new energy storage facility to be built in Pori Energia’s Aittaluoto site. The project will enhance the flexibility of Pori Energia’s district heat production and improve the utilization of the recently completed electric boiler in varying electricity market conditions.
The energy storage facility will be constructed in the Aittaluoto power plant area. Nakkila Works Oy’s delivery includes an 8,500 m³ district heating accumulator along with its equipment and process systems. The design phase is already underway, construction of the heat accumulator will begin in autumn 2026, and commissioning of the energy storage is expected to take place in summer 2027.
“It is great to work together with a major local energy company on a project that improves the energy efficiency of district heating production in the region and supports the transition towards low‑emission solutions,” says Jussi Kivioja, CEO of Nakkila Works Oy.
The previous energy storage projects delivered by Nakkila Works Oy to Pori Energia were completed in 2023. This new project continues the long-term cooperation between the companies and further strengthens Nakkila Works Oy’s position as a significant supplier of energy storage solutions in Finland and the Nordic countries.
