Finland s solar power supply system

According to the preliminary data of the Energy Authority, at the end of 2023, Finland had approximately 1,000 MW of installed solar power production capacity, 936 MW of which was micro-generation and 50 MW from industrial-scale power plants. Unconnected capacity totalled approximately 23 MW.

LUT has modeled an emission-free energy system and demonstrated that the share of solar energy in Finnish energy production should rise to 10 percent by 2050. That would mean a leap from the current 635 megawatts to 35 000. The rooftop potential of all Finnish buildings (residential, administrative, industrial) is about 34 000 megawatts.

In Finland, a number of hybrid projects are in the pipeline, combining wind, solar and also energy storage. These solutions will balance our energy system. On a global scale, solar power is one of the fastest growing forms of energy generation – its size and importance in the world's energy mix is huge, larger than wind power.

The energy transition is increasing the need for renewable forms of energy, as fossil fuels need to be replaced cost-effectively. The spotlight is now on wind and solar power, which still have plenty of growth potential. Wind power currently accounts for 20 per cent of Finland's electricity consumption, while solar power makes up just one per cent.

In addition to wind power, we also need plenty of solar energy, for which Finland has excellent prospects. Solar power is particularly well suited as a counterpart to wind power. These two emission-free energy sources complement each other: solar energy is available in summer and during the day, while the highest winds occur on average in winter.

The total capacity increased by more than 300 MW over the year. According to the preliminary data of the Energy Authority, at the end of 2023, Finland had approximately 1,000 MW of installed solar power production capacity, 936 MW of which was micro-generation and 50 MW from industrial-scale power plants.
