The Hanasaari A power plant was built in 1960–1967. It was decommissioned in 2000 and dismantled in 2008.[1][2] There is an experimental documentary Hanasaari A by Hannes Vartiainen and Pekka Veikkolainen.[3]

Hanasaari B power plant was built next to Hanasaari A, and was commissioned in 1974 to 1977. Hanasaari B is a coal-fired cogeneration plant producing electricity and heat. The output capacity of the plant is 228 MW of electricity and 445 MW of heat.[4]

In 2014–2018, Helsingin Energia planned to convert Hanasaari B for combustion of biomass.[5] The biomass furnace was being setup alongside one of the existing coal units, which would be kept in reserve in case of emergency.[4] The coal plant was expected to be decommissioned by 2025.[5]

In 2021, the projected retirement was moved forward: According to the new schedule, the plant will be put into reserve operation for the heating season 2022–2023, when the Vuosaari bioheat plant goes into production. By April 2023, the Hanasaari power plant was expected to be closed permanently.[6]
