Solar and wind power
The energy transition requires the deliberate adaption of renewable energy as part of a comprehensive energy production, and it will steer the operations of many energy companies in the future, including Oulun Energia. A significant investment in wind and solar power is part of Oulun Energia’s goal of complete carbon neutrality by 2030.
Solar and wind power are already part of our electricity production portfolio
We already participate in wind power production as a shareholder in wind power production companies and through long-term electricity supply contracts. We own shares of wind power through EPV Windpower in the Metsälä wind farm in Kristiinankaupunki and the Santavuori wind farm in Ilmajoki. We have signed power purchase agreements with Taaleri Energia Oy for the Oltava wind farm and with Tuulivoimayhtiö Pohjoistuuli Oy for the Tyrinselkä 2 wind farms.
We also operate our own 5-megawatt solar power plant in Paarmala, Raahe, which produces approximately 5 gigawatt hours of electricity annually. The Paarmala solar power plant is connected to our multi-energy optimisation service, allowing its renewable electricity production to be optimised and flexibly utilised in the spot market as well as in Fingrid’s reserve markets.
Our goals for increasing the share of solar and wind power
We are continuing to significantly increase the share of solar power in our production, with the goal of generating 100 gigawatt hours of energy from solar power by 2026.
We are involved in the construction of one of Finland’s largest solar power parks in Lapua. The solar power plant, being built by EPV Energia, is scheduled for completion in 2025 and will produce over 80 gigawatt hours of electricity annually. Oulun Energia’s share of the plant is 20 megawatts.
New solar power projects are being explored through Suomen Aurinkovoima Oy, a company established by Oulun Energia and four other Finnish energy companies. In 2025, Suomen Aurinkovoima Oy and Oomi Solar Oy signed an agreement for a solar power project portfolio of approximately 250 megawatts, comprising ten separate projects. This is a significant development in Finland’s solar power market.
As for wind power, our goal is to triple production by 2026, reaching 600 gigawatt hours of wind electricity annually.
We are participating in a wind farm being built by OX2 in Lestijärvi, which is expected to be completed in 2025. The wind farm’s annual energy production will exceed 1.3 terawatt hours. We are also continuously exploring new wind power opportunities and project prospects.
Our main ongoing solar and wind power projects
Solar power project at Heinineva, Lapua
EPV Energia will build the solar power field on the former peat production area. In the first phase, the solar power field will produce approximately 70 gigawatt hours of electricity per year. Oulun Energia’s share of this is about 30% or 20 megawatts.
Lestijärvi wind farm project
In addition to Oulu Energia, the wind power project involves Kymppivoima and Kuopio Energia. The total capacity of the wind farm is 455.4 MW, of which Oulun Energia's share is 25%, or 114 MW.
