Our objective is that in 2020, one half of the electricity and heat we procure will have been generated from renewable and CO2-free sources. We will be achieving this goal even earlier. In order to reach our target, several projects set out in the Group’s strategy and Environmental Programme will be implemented. We are developing our energy supply via our own high- and reserve-power plants as well as via our affiliate companies. The largest impact on the quantity of renewable energy and emission reductions will come from the new multiple-fuel power station completed in Naantali at the end of 2017 (Turun Seudun Energiantuotanto Oy).
Fuels for heat supply 2017
Origin of district heat
District heat is produced at the Naantali power station, Oriketo biothermal plant and Kakola heat pump plant. In addition, the pellet- and oil-fuelled standby and peak-lopping heat plants located in Turku are used during the low winter temperatures and when faults occur.
Supply and emissions
Heat emissions / sold energy 336,5 kgCO2/MWh
District cooling emissions / sold energy 15,0 kgCO2/MWh
Steam emissions / sold energy 350 kgCO2/MWh
Origin of electrical energy
The distribution of origins was calculated on the basis of the national residual mix reported by the Finnish Energy Authority and the guarantees of origin obtained by Turku Energia. The national residual mix for 2017 has not yet been published, the data will be updated during Summer 2018. This describes the situation in 2016.
The residual mix contains electricity generated by fossil fuels and nuclear power as well as its share of renewal electricity-based electricity, which has not been sold separately with guarantees of origin.
CO2 emissions from electricity sold by Turku Energia are 215 g/kWh on average. The amount of nuclear fuel used on average in Finland in 2016 was 0.83 mg/kWh.
