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.
