On activities of combined heat and power plants in 2012

17.05.2013

In 2012, in Latvia there were 133 active combined heat and power (CHP) plants with total electrical capacity 1021.0 megawatts (MW). Provisional data compiled by the Central Statistical Bureau of Latvia show that 70.1% of the total heat generated by CHP plants were produced in Riga. CHP plants produced 2339 gigawatt hours (GWh) of electricity and 4688 GWh of heat – 62.9% of the total heat produced. Cogeneration is simultaneous production of heat energy and electricity in a united cycle.

In comparison with 2011, the number of CHP plants has grown by 60.2% and electrical capacity – by 6%. CHP plants of Riga had the highest installed electrical capacity – 881.2 MW. In 2012, the number of CHP working on biogas has risen by 120%, as compared to 2011.

There are two types of CHP plants:

  • public CHP plants primary activity of which is generation of heat (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).

98 out of 133 CHP plants active in 2012 were public cogeneration plants with installed electrical capacity 982.0 MW, the number comprises 96.2% of the total installed capacity of CHP plants, and 35 were autoproducer CHP plants with installed electrical capacity 39.0 MW.

In 2012, for the production of heat and electricity CHP plants were mainly using natural gas (85.7%), as well as biogas, fuelwood, coal, residual (heavy) fuel oils and bio-diesel. Consumption of natural gas in CHP plants has dropped from 92.3% (in 2011) to 85.7% (in 2012).

Annual data on activities of CHP plants in 2012 in the CSB database section Environment and Energy/ Energy will be published in June.
