History
editThe first power plant in Hanasaari area, the Suvilahti steam power plant, was built in 1909. It stayed in operation until commissioning the existing Hanasaari power plant. Its facility is classified as an architecturally and historically significant building.
The Hanasaari A power plant was built in 1960–1967. The Hanasaari B power plant, built next to Hanasaari A, was commissioned in 1974. Hanasaari A was decommissioned in 2000 and dismantled in 2008. The coal store to be moved to the silos to be built next to the Hanasaari B as the southern part of the site will be restored for residential use. The residential area, named 'Tropaion', is designed by the Finnish architect bureau ALA.[2][3] There is an experimental documentary Hanasaari A by Hannes Vartiainen and Pekka Veikkolainen.[4]
Description
editHanasaari B is a coal-fired cogeneration plant producing electricity and heat. The output capacity of the plant is 220 MW of electricity and 420 MWt of district heating.[5][6] It is equipped with two furnaces.[7]
In the 2010s, a separate peak-load and reserve heating plant was built in front of the power plant. Helsingin Energia planned to modernize the Hanasaari power plant for combustion of biomass (wood) between 2014 and 2018.[8] The biomass furnace would be set up alongside one of the existing coal units, which would be kept in reserve in case of emergency.[7]
The Helsinki-owned energy company Helen Oy shut down all operations at the Hanasaari plant on Saturday 1 April 2023 as part of Helsinki's goal to reach carbon neutrality by the year 2030. The closure was referred as an "important, historic change for the capital, the country and the world at large" by the Mayor Juhana Vartiainen.[1]
