On activities of combined heat and power plants in 2010

18.05.2011

Data of the Central Statistical Bureau show that in 2010 in the Republic of Latvia there were 71 active combined heat and power (CHP) plant with total electrical capacity 947.5 megawatts (MW). These CHP plants produced 3050 gigawatt hours (GWh) of electricity and 4673 GWh of heat energy, and it is 58.7% of total volume of heat produced.

Cogeneration is simultaneous production of heat energy and electricity in united cycle.

In comparison with 2009, electrical power of cogeneration plants has increased by 1.4%.CHP plants of Riga had the highest installed electrical capacity – 876.3 MW.

There are two types of CHP plants:
  • public CHP plants primary activity of which is generation of heat energy (division 35 of NACE Rev.2.);
  • autoproducer CHP plants are generating heat for their own production and technological use and partly for sale (NACE Rev.2., except division 35 of NACE Rev.2).

Out of 71 CHP plant active in 2010 56 were public cogeneration plants with installed electrical capacity 932.8 MW, it is 98.4% of total installed capacity of CHP plants, and 15 were autoproducer CHP plants with installed electrical capacity 14.7 MW.

In 2010 for the production of heat energy and electricity CHP plants mainly used natural gas (98.1%), as well as biogas, fuelwood, coal, residual (heavy) fuel oils and bio-diesel oil.

Out of 71 CHP plant active in 2010 56 plants (both public and autoproducer) with total electric capacity 870 MW were active more than 6 months, of which:

  • 3 combined-cycle turbines with electrical capacity 803 MW;
  • 1 gas turbine with heat utilisation;
  • 48 internal combustion engines with electrical capacity 61 MW;
  • 3 steam backpressure turbines with electrical capacity 4 MW;
  • 1 condensing steam turbine.

 In June 2011 in section annual data of the CSB data base (www.csb.gov.lv) subject “Energy” several tables on activities of CHP plants in 2010 will be published:

  • Number of CHP plants, electrical capacity, heat energy and electricity produced (EN18);
  • CHP plants by fuel type (EN20);
  • Heat balance in statistical regions and cities under state jurisdiction (EN23);
  • Heat produced in autoproducer heat plants and CHP plants by kind of economic activity (EN24);
  • Fuel consumed by autoproducer heat plants and CHP plants in breakdown by kind of economic activity (EN25);
