In 2009, IES-Holding power plants produced 63.3 billion kWh of electric energy and 118.6 million GCal of heat. Compared to 2008, the electric energy output reduced by 7.77%, while heat output showed a slight drop at the rate of 1.46%. According to Trading Division specialists, the reduction of output in 2009 was caused by a slump in the demand - by 6-8% depending on the Unified Power System. The condensation load of the heat stations - the final step in wholesale trade of electric energy and power - was much reduced. Warm winter of 2008-2009 increased the water level in the rivers of European Russia and Ural which allowed hydropower plants to extend their output in winter and spring 2009. From mid-October and to the end of the year atomic power plants augmented their load sharply reaching the peak of 22.75 GW on December, 25. As for TGC-6 and Volga TGC, a comparatively large decrease in their output (8.6% and 8.9%) was caused by hydropower and atomic power plants in their regions operating at a greater load than in 2008. The decrease in heat energy output was caused by large industrial customers reducing their consumption of steam. The reduction was partly compensated by growth in the output which was provoked by abnormally low temperature in December. The only company to increase its heat energy production (1.4%) was TGC-5, because individuals account for the largest part (60 to 70%) of its consumers. | | 2008 (electric energy, million KWh) | 2009 (electric energy , million KWh) | TGC-5 | 11287,63 | 10631,151 | TGC-6 | 13082,753 | 11963,56 | ÒGC-7 | 27889,955 | 25409,44 | TGC-9 | 16340,47 | 15268,6 | Total: | 68600,808 | 63272,751 |
