Sredneuralskaya GRES belonging to PJSC “Enel Russia” has removed from operation its turbo generators No.1, 2, 5 (with gross capacity of 78 MW) and boilers No.2, 6.
Decommissioning of this equipment was performed within the framework of the project for modernization of the district heating system, which was completed in 2016. This project intended to remove obsolete equipment from the production cycle of heating energy supplied to Ekaterinburg, Verkhanya Pyshma and Sredneuralsk.
Therefore, currently electrical gross capacity of SUGRES is 1578.5 MW, heating gross capacity remained the same and is 1327 Gcal.
For the last 20 years, turbo-generators No.1, 2, 5 have produced more than 4 billion kWh of electrical energy.
Recently this equipment was kept in the general reserve.
Let’s make a reference to the history, turbine unit No 1 was commissioned in 1936 and turbo unit No 2 – in 1937. Turbine No 5 was supplied to SUGRES after the Great Patriotic War under the reparation agreement, as parameters of this turbine complied with characteristics of boilers installed in the power plant. In 1947, the turbine was dismantled from Reichstag and, in 1949, it was installed at SUGRES. This the only turbine with a unique construction: it is rotating the other way round in comparison with other turbines.
Sredneuralskaya GRES is one of the largest heat suppliers in the Sverdlovsk region; it produces about 30% of all thermal energy and hot water consumed by Ekaterinburg, and covers about 100% of energy needs of nearby towns Verkhnaya Pyshma and Sredneuralsk. SUGRES produces 10% of all power output in the electrical grid of the Sverdlovsk region.
