Efficiency of conventional thermal electricity generation (ENER 019) - Assessment published Apr 2012
-
The efficiency of electricity and heat production from conventional thermal power plants improved between 1990 and 2009 by 5.5 percentage points (from 45.4% in 1990 to 50.9% in 2009). Between 1990 and 2005, the improvement was even greater at 7.0 percentage points (from 45.4% in 1990 to 52.4% in 2005). The improvement until 2005 was due to the closure of old inefficient plants, improvements in existing technologies, often combined with a switch from coal power plants to more efficient combined cycle gas-turbines. Between 2005 and 2009, there was a decline in efficiency of electricity and heat production from conventional thermal power plants of 1.5 percentage points (from 52.4% in 2005 to 50.9% in 2009) because of lower heat production.

Combined heat and power (CHP) (ENER 020) - Assessment published Apr 2012
-
In 2009, the share of electricity produced from combined heat and power (CHP) in the EU-27 was 11.4% a modest growth from 2008 (11.0%), but it has changed little from earlier years, where in 2005 11.1%, despite strong policy support to promote the technology in many Member States. High gas prices, inconsistent energy policies and relatively low electricity prices have kept the competitiveness of gas-fired CHP-plants marginal in many Member States, though there are signs that this is changing. CHP is also a significant contributor to the heat supply in Europe, supplying 15.2%. However, the EU-15 indicative target of 18% of CHP electricity in gross electricity production by 2010 will be missed (currently 11.0% of total gross electricity production in EU-15).
