Growth of the Combined Heat and Power Generation
In August 2013 SEWRC updated the register of the certificates of origin of cogenerated power, produced in 2012.
The quantity of the cogenerated power by district heating companies and industrial plants (autoproducers) amounts to 3 881.74 GWh, which is a growth of 9.8%, compared to 2011. This growth is due to increased production effected by both, district heating companies and autoproducers. The cogenerated power has a share of 8% of the gross power production in 2012.
There are 4 new autoproducers in the list of generators, which have received certificates.
The high-efficiency power generation is 2 773.6 GWh in 2012, which has marked a decrease of 18% compared to 2011. The high-efficiency cogeneration had a share of over 90% of the cogeneration in recent years, but in 2012 this share was 71%.
| 2009 | 2010 | 2011 | 2012 | |
| Combined power generation (GWh) | 3 678.2 | 3 839.3 | 3 534.9 | 3 881.7 |
| Highly efficient combined power generation (GWh) | 3 382 | 3 722.8 | 3 385.8 | 2 773.6 |
| Share of the highly efficient combined power generation (%) | 91.9% | 97% | 95.8% | 71.5% |
Only 7.8% of the 1 021.48 GWh generated by Sofia District Heating Company (Sofia DHC) in 2012 were validated by SEWRC as high-efficiency generation, unlike the previous two years, when all the cogenerated power by the two plants of the company was validated as high-efficiency. The decision of the regulator indicates that the fuel savings of the installations of TPP Sofia and two of the installations of TPP Sofia Iztok were less than 10%. Only one installation in TPP “Sofia” has achieved fuel savings greater than 10% and the quantity of high-efficiency cogenerated power is 80.1 GWh. According to article 14(1) of the Ordinance on validation of the quantities of power produced by combined heat and power generation: “Combined heat and power generation is defined as high-efficiency when it leads to not less than 10 per cent annual savings of the fuel, which would be necessary for the separate generation of the same quantities of heat and power”.
As a result of the reduced quantities of high-efficiency power cogenerated by Sofia DHC in 2012, the autoproducers overtook the DHCs by producing 19% more high-efficiency cogeneration power, than them.
There has been no change in the ranking of the leaders in the power cogeneration. In the DHCs’ group, with a share of 46%, Sofia DHC has remained on the top, followed by Pleven DHC – 14% and EVN Bulgaria DHC – 13%.
Brikel has topped the list of autoproducers for yet another year with 39%, followed by Vidahim – 21% and Deven – 12%.
