Overview
Suomen Voima Oy is a Finnish power company whose energy portfolio of more than 1.5 TWh is spread across the Nordic countries. Its generation and project sites include Parha and Hankila in Finland and Noste in Finland, as well as Litlebø and Stardalen in Norway, reflecting a diversified Nordic asset base rather than a single-market utility. The company operates under the Mankala principle, a Finnish model in which a group of owners jointly funds and owns an energy company and receives electricity or other output in proportion to their holdings rather than dividends. Through this structure, Suomen Voima grants its 18 owners an effective investment platform into diversified energy assets. All of the owners are Finnish municipally or privately owned power companies, and many of these companies have a history spanning over a century in the domestic energy sector. Suomen Voima describes itself as actively seeking investment and electricity procurement opportunities. It positions itself as a cooperative vehicle for Finnish energy companies that want exposure to a broader, Nordic-wide portfolio without each owner having to build that portfolio alone. Inquiries are directed to the company by email at suomenvoima (at) suomenvoima.fi. Because the company is owned by its member power companies rather than listed on a stock exchange, it is a privately held corporate entity. Its brand identity is tied less to consumer retail supply and more to wholesale power, procurement, and joint investment in energy assets across Finland and Norway.
History
Suomen Voima Oy is a Finnish power company organized around the Mankala principle, a long-established Finnish ownership model in which a group of industrial or utility owners jointly funds an energy company and receives its output in proportion to ownership instead of dividends. Under this structure, Suomen Voima functions as a shared investment and procurement vehicle for its owners rather than as a conventional listed utility. The company's energy portfolio exceeds 1.5 TWh and is spread around the Nordics. Its named sites include Parha, Noste, and Hankila in Finland and Litlebø and Stardalen in Norway, indicating a portfolio that combines Finnish and Norwegian assets. This geographic spread gives the owners exposure to Nordic power markets and to a mix of energy assets rather than a single domestic facility. Suomen Voima has 18 owners. All of them are Finnish municipally or privately owned power companies, and many of these owner companies have histories spanning over a century in the domestic energy sector. This ownership base ties Suomen Voima to Finland's municipal and private energy tradition, in which local power companies cooperate on larger generation and procurement projects that would be difficult to finance individually. The company states that it actively seeks investment and electricity procurement opportunities, positioning itself as an ongoing platform for adding diversified energy assets. Its public contact channel is an email address at suomenvoima.fi. As a company owned by its member power companies, it is privately held and does not appear to be listed on a stock exchange.
