Last year, cogeneration plants produced 30% less electricity / articles

Statistics Estonia state that this was mainly influenced by the increase in power generation in hydropower plants due to high water flow and the corresponding decrease in electricity prices, as well as lower heat demand due to hot weather conditions, which led to cogeneration There was less power generation in the. Plant.

In 2020, the cogeneration plants produced 5038.5 GWh of heat energy or 6% less than in 2019. The share of heat produced in co-generation plants in 2020 was 67% of the total amount of heat produced in the country.

The number of cogeneration plants has doubled over a 10-year period from 2011 to 2020, but is decreasing from 2018.

In 2017 and 2020, there were 29 and 42 fewer co-generation plants operating, respectively, compared to 2014, when the largest number of co-production plants were operating in the last ten years – 204 co-generation plants. The termination of state aid for the sale of electricity through compulsory procurement led to the closure of many co-generation plants.

The total power capacity of the co-generation plants reached 1,274.2 MW in 2020, which is 4.5 MW more than in 2019, but 24.9 MW less than in 2017. In ten years, the electric capacity of the co-generation plants has increased by 32% or 1.3 times.

The share of power generation capacity of general-use cogeneration plants in 10 years was on average 97%, while the power capacity of enterprise cogeneration plants was 3% of the total power capacity of cogeneration plants. In 2020, four general-purpose co-generation plants with a capacity of more than 20 MW had 83% of the total power capacity in the co-generation plants, but 36% of the total power capacity in the country – three of them operated in Riga. , – in the Zemagle region.

In the last 10 years, the share of the power capacity of fossil energy cogeneration plants has been decreasing and the share of the electrical capacity of renewable energy resources (RES) co-generation plants has been increasing. The largest increase in electric capacity of RES cogeneration plants was seen in 2012 and 2013 (up to 80.2 MW) and from 2013 to 2020 the share of power capacity of RES cogeneration plants was in the range of 9% -12% of the total power. Capacity in the cogeneration plants, however, compared to the previous year, in 2020 the power capacity of RES cogeneration plants was 1.3 MW and 156.3 MW.

The highest share of the power capacity of RES cogeneration plants in 2020 was at Vidzame (98%) and Zemagle (96%), where the total power capacity was 29 MW and 59.1 MW respectively. The share of the power capacity of RES cogeneration plants in Kurzame and Pieriga was 4% and 71% of the total power capacity of the cogeneration plants respectively – 24.7 MW in Kurzame and 51.0 MW in Pieriga. The largest share of the power capacity of fossil cogeneration plants is in Riga and Latgale – 99% and 72% of the total power capacity of cogeneration plants in the region (Riga – 1,069.8 MW, Latgel – 40.6 MW, respectively).

The amount of electricity produced at RES cogeneration plants in 2020 was 864.8 GWh, 7% less than the previous year, but the power generation from RES to co-generation plants has increased 7-fold in 10 years. The increase in electricity produced by RES cogeneration plants has been facilitated by state aid programs.

The amount of electricity produced at RES cogeneration plants in 2020 accounted for 24% of the total local power generation from RES in the country (14% of biomass cogeneration plants, 10% – biogas cogeneration plants).

Natural gas and firewood are mainly consumed in cogeneration plants for energy production. In 2020, 21.0 petajoules (PJ) of natural gas and 12.4 PJ of fuel wood were consumed, a total of 20% less than in 2019. Within ten years, the share of natural gas consumption in cogeneration plants has fallen from 93% to 58%, while the share of RES consumption has increased considerably, reaching 42% in 2020.

Latvia aims to achieve a 50% share of RES in gross final energy consumption by 2030 and reduce Latvia’s energy dependence on energy imports. Latvia’s RES had a 41% share in final energy consumption in 2019.
