5.2 electricity generation
The development of the electricity supply sector is characterised by a dynamically growing renewable energy market and an increasing share of renewable electricity. This will compensate for the phasing out of nuclear energy and reduce the number of fossil fuel-fired power plants required for grid stabilisation. By 2050, 94% of the electricity produced in Finland will come from renewable energy sources. ‘New’ renewables – mainly wind and PV – will contribute 49% of electricity generation. Already by 2020 the share of renewable electricity production will be 52% and 74% by 2030. The installed capacity of renewables will reach 21 GW in 2030 and 43 GW by 2050.
Table 5.1 shows the comparative evolution of the different renewable technologies in Finland over time. Up to 2020 hydro, biomass, and wind are the main contributors of the growing market share. After 2020, the continuing growth of wind will be complemented by electricity from photovoltaics. The Energy [R]evolution scenario will lead to a high share of fluctuating power generation sources (photovoltaic, wind and ocean) of 35% by 2030, therefore the expansion of smart grids, demand side management (DSM) and storage capacity from the increased share of electric vehicles will be used for a better grid integration and power generation management.
