In 2020, compared to 2019, amount of electricity produced in CHP plants fell by 30 %, which was mainly affected by such factors as growth of output of electricity in hydro power plants due to a higher water inflow and corresponding drop of prices of electricity, as well as reduced demand for heat due to warmer weather conditions, which determined a lower output of electricity in CHP plants.
In 2020, 5038.5 GWh of heat was produced in CHP plants or 6 % less than in 2019. In 2020 share of heat produced in CHP plants comprised 67 % of total amount of heat produced in the country.

*P – electrical capacity
Over the ten year period from 2011 to 2020 the number of CHP plants has doubled, but since 2018 it is decreasing. In 2019 and 2020, respectively, 29 and 42 CHP plants less were active than in 2017, when the largest number of CHP plants over the last ten years was active – 204 CHP plants. Several CHP plants stopped their activity as state support in the form of mandatory procurement of electricity ended.
In 2020 total electrical capacity of CHP plants reached 1 274.2 MW, which is 4.5 MW more than in 2019, but 24.9 MW less than in 2017. Electrical capacity of CHP plants has grown by 32 % or 1.3 times over the past ten years.
Share of electrical capacity over the past 10 years in CHP plants fuelled by fossil fuels has reduced and share of electrical capacity in CHP plants fuelled by renewable energy sources (RES) has increased. The largest share of electrical capacity of RES-fuelled CHP plants was observed in 2012 and 2013 (by 80.2 MW) and from 2013 until 2020 share of electrical capacity of RES-fuelled CHP plants comprised 9 % – 12 % of the total electrical capacity in CHP plants, however, compared to the previous year, in 2020 electrical capacity of RES-fuelled CHP plants was 1.3 MW less reaching 156.3 MW.
