Probably each of us heard more than oncephrases: Kostroma SDPP, Zaporozhskaya SDPP, Konakovskaya SDPP and many other names of cities and towns (and even entire states), together with the letters of SDPP. The decryption of these letters (abbreviations), denoting a phrase, sounds like this: State District Electric Station (SDPP). In the world, the very first power plant, called "Transmission", was built in the suburbs of Moscow in 1912-1914. Developed the project and led the construction of Russian engineer R.E.Klasson. The power plant worked on local fuel - peat. And it had a power of 15 MW. It provided electricity for the growing needs of Moscow and the surrounding area.
К концу двадцатого века в термине ГРЭС the decryption lost the “district”, and in the early 2000s the “state” part, since powerful thermal power plants already served not the region, but the entire administrative regions and even entire independent countries. For example, almost all of Estonia is supplied with electricity by two powerful TPPs - the Baltic (1.654 GW) and the Estonian - 1.6 GW. In Lithuania, one GRES (Lithuanian - 1.8 GW) also provides most of the so-needed independent electricity. In the Russian Federation, more than 250 thermal power plants (mainly TPP and CHP) are in operation, almost all of them were built during the Soviet era. The “state” part of the term has become in many cases private or joint-stock.
Today in the term GRES, the decoding of whichas it was shown earlier, the words “state district” are almost useless to replace, most often, with the term functional description “condensation”. Namely - "Condensation Electrical Station" (IES). The term GRES, the decoding of which has lost its meaning, is used by inertia of thinking or by habit.
The number of these power plants - GRES, or, more precisely, IES, includes Serovskaya in the Yekaterinburg region (in the city of Serov), and Ryazan (in the same-named Ryazan region, in the village of Novomichurinsk).
In 2010decided to modernize at Serovskaya GRES - to build a new power unit with a capacity of 419.5 MW. This unit will be steam-gas, the manufacturer - the company "Siemens" (Germany). Due to the combined-cycle technology, the efficiency of the unit will increase to 58% or more. The launch of the new part is scheduled for 2014.
Рязанская ГРЭС – тепловая конденсационная power plant with a design capacity of 3,600 MW. One of the largest thermal power plants in the USSR. It bears its name not by the nearest settlement, but by the regional center. The power plant in the Soviet era was 2,650 MW, and for heating it gave 180 Gcal / hour. In Soviet times, four power units of 300 MW each and three 800 MW each were laid in the construction project. Four 300 MW each and two 800 MW each were built. The fuel used is coal near Moscow and fuel oil. Its two chimneys are among the ultrahigh chimneys of the world (their height is 320 m). Later, natural gas was added to the fuel. In recent years, the plant has been upgraded (the gas turbine unit was installed with an electric generator) and its capacity increased to 3,200 MW.
