What is the amount of energy produced (including distributed production) in Helsinki? Where is it produced (-> emissions)? Which processes are used in its production?


Energy production capacity in Helsinki. The different scenarios are based on Helsinki energy decision 2015.

This code is used to fetch the ovariables on this page for modelling.

+ Show code


This page contains data about the heat plants in Helsinki. It tells, how much and what type of energy a plant produces per unit of fuel, how much the plants cost and the locations of the power plant emissions. This data is then further used in the model.

Amount produced is determined largely by the energy balance in Helsinki and Helsinki energy consumption. The maximum energy produced and fuels used by of all Helen's power plants can be found here:

Notes about the data in the table:

  • Household air heat pumps data from heat pump comparison[1]
  • Household geothermal heat data from Energy Department of the United States: Geothermal Heat Pumps[2]
  • Small-scale wood burning data from Energy Department of the United States: Wood and Pellet Heating[3]
  • Loss of thermal energy through distribution is around 10 %. From Norwegian Water Resources and Energy Directorate: Energy in Norway.[4]
  • Sustainable Energy Technology at Work: Use of waste heat from refining industry, Sweden.[5]
  • Chalmers University of Technology: Towards a Sustainable Oil Refinery, Pre-study for larger co-operation projects[6]
  • CHP diesel generators are regular diesel generators, but they are located in apartment houses and operated centrally. This way, it is possible to produce electricity when needed and use the excess heat, instead of district heat, to warm up the hot water of the house.
  • Motiva estimates for heat pumps processes and costs for heating:[7]
    • Mechanical heat pumps usually have COP (coefficient of performance, thermal output energy per electric input energy needed) is 2.5 - 7.5.
    • In district heating, mechanical heat pumps have typically COP around 3.
    • Absorption heat pumps have COP typically 1.5 - 1.8. They do not use much electricity but they need either hot water or steam to operate. Therefore, they are not suitable for producing district heat from warm water with temperatures in the range of 25 - 30 °C (Neste) or 10-15 °C (sea heat).
    • The report uses these values for energy prices (€/MWh): bought electricity 50, process steam 25, wood chip 20, district heating 40, own excess heat 0.
    • The investment cost of a heat pump system (ominaiskustannus) in the cases described in this report were 0.47-0.73 M€/MWth for mechanical heat pumps and 0.072 - 0.102 M€/MWth for absorption heat pumps. These values do not include the pipelines needed, which may vary a lot; in these cases the pipeline costs were 0.1 - 2.5 times the cost of the heat pump.
    • The energy efficiency is theoretically COP = Tout / (Tout - Tin), and the actual COP values are typically 65 - 75 % of that. If we assume that we want 95 °C district heat out, we get
      • for sea heat pumps: COP = 368 K / (368 K - 283 K) = 4.3 ideally and in practice 2.8 - 3.2. Electricity needed per 1 MWh output: 0.31 - 0.36 MWh.
      • Neste process heat: COP = 368 K / (368 K - 303 K) = 5.7 ideally and in practice 3.7 - 4.2. Electricity needed per 1 MWh output: 0.23 - 0.27 MWh (plus what is needed for pumping the heat for 25 km, say + 0.04 MWh)

Plant specifications

These equations below aim to reflect the energy production facilities and capabilities. The min and max values tell about the range of energy production of the plant, and the cost values tell the costs of building and running the powerplant.

Note! Maintenance cost only contains costs that do not depend on activity. Operational cost contains costs that depend on activity but NOT fuel price; those are calculated separately based on energy produced.

Fuel availability


The byproducts of forest industry make up the bulk of fuel wood, and its quantity is almost completely dependent of the production of the forest industry's main products. Therefore it makes sense to calculate the amount of fuel wood usable in the future using the predictions about the volume of forest industry's production in coming years.

For example, the maximum potential production of woodchips is calibrated so, that it will reach 25 TWh in year 2020, and it is expected slowly increase to 33 TWh by year 2050. The production potential for firewood (for small scale heating) is expected to remain about the same at just under 60 PJ. The import of wood fuels is estimated to be 3 TWh at most. [20]

Fuel use by heating type
