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

Heat and electricity produced in CHP plants in 2000 – 2011 (GWh)

As compared to 2010, electrical power of cogeneration plants has increased by 1.95%. CHP plants in Riga had the highest installed electrical capacity – 880.1 MW.

Number of CHP plants and installed electrical capacity (MW) in 2010 and 2011 by statistical region

There are two types of CHP plants:

• public CHP plants the primary activity of which is generation of heat energy and electricity (division 35 of NACE Rev.2.);
• autoproducer CHP plants, which generate heat and electricity for their own production and technological use and partly for sale (NACE Rev.2., except division 35 of NACE Rev.2).

Number of public CHP plants and installed electrical capacity (MW) in 2011

In 2011 for the production of heat energy and electricity CHP plants used mainly natural gas (92.3%), as well as biogas, fuelwood, coal, residual (heavy) fuel oils and bio-diesel oil.

Out of 84 CHP plant active in 2011, 64 plants (both public and autoproducer) with the total electric capacity of 883 MW were active more than 6 months.

In June 2012 in the annual data section of the CSB data base (www.csb.gov.lv) under subject Energy several tables on the activities of CHP plants in 2011 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);
