Jyväskylän Voima Oy
Jyväskylän Voima Oy was established in 2006 to operate the new plant at Keljonlahti, which uses biofuel.
Construction work on the power plant began in October 2007 and the plant was first deployed during the summer of 2010. Suomen Voima owns close to 10% of the company, which entitles it to a share of 28 MW of the output of the condensing power production. The plant uses wood, peat and coal as fuels.
