Helsinki's Hanasaari B power plant to close down by 2025, Vuosaari to receive new unit

Helsinki Energy presents massive EUR 3 billion renewal programme aimed at carbon neutral future


Helsinki's Hanasaari B power plant to close down by 2025, Vuosaari to receive new unit

Helsinki Energy (Helsingin Energia) has set out to modernise its entire energy production. The plans include for example the shutting down of the Hanasaari B power plant and the building of a new unit in Vuosaari.
      Last night a gigantic EUR 3 billion investment plan to be implemented over the next 20 years was presented to the energy company’s board of directors.
     
The realisation of the development plan would have a dramatic effect on Helsinki Energy’s carbon emissions in 2030.
      Compared with the 1990 level, the emissions would fall by no less than 98 per cent.
      By then 38 per cent of the production would be based on renewable energy.
      As a result of the renewal measures, the price of district heating is expected to rise by 40-50 per cent.
     
Helsinki Energy also estimates that the modernisation will have a strong negative effect on the company’s profit-making capacity.
      Each year Helsinki Energy transfers around EUR 200 million into the coffers of the City of Helsinki.
      In the city’s budget the sum is equivalent to 2% of all the tax revenue.
     
Helsinki Energy’s plan of action is twofold.
      In the first phase (2014-2018), the Hanasaari and Salmisaari coal power plants will be fitted with new equipment that will enable the units to utilise biofuel, which in practical terms means wood.
      The objective is that after the alteration work, biofuel would constitute 40 per cent of the fuel used by these two installations. The exploited technology is based on gasification of biomass.
      Simultaneously the procurement of biomass, in other words wood, plus the required logistics, will be organised.
      Efforts will be made to place the intermediate depot of the fuel in the vicinity of Helsinki, for example in the Tolkkinen district of the nearby city of Porvoo.
      The energy company’s aim is also to increase the production of wind energy by up to 600 gigawatt hours, after which the total share of renewable energy would be 21 per cent of the production.
      In Helsinki the offshore area south of the island of Harmaja has been outlined as the location of the wind park.
     
In the second phase after the year 2020, Helsinki Energy plans to erect - together with some co-operation partner - a wood-fired gasworks (using forest residue) along a natural gas pipeline.
      The partner would have to be a biomass acquisition organisation with expertise in natural gas systems.
      The gas will then be utilised in Vuosaari’s gas power plants and certain gas-fired heating plants.
      In the eastern suburb of Vuosaari a new multi-fuel power station will be built to replace the Hanasaari power plant, the operation of which will cease altogether in 2025.
      In connection with the new power station, an energy tunnel will be constructed from Vuosaari to the central city area.
      Helsinki Energy also proposes measures to reclaim carbon dioxide and to store it with the new power plant and also in Salmisaari.
      This would be realised around 2030.
     
Behind the published action plan is, among other things, the Helsinki City Council’s decision from two years ago for the energy companies to reduce their carbon emissions by 20 per cent from the 1990 level, and raise the use of renewable energy to 20 per cent.
      After a hearing by the board of directors, the development plan will enter a committee round.
      The aim is for the City Council to decide on the matter in the spring.
