CHPP-26 is the largest combined heat and power plant in Moscow in terms of installed electric capacity. The power plant provides district heating to industrial enterprises, public and residential buildings with a population of more than 2 million people in the Chertanovo, Yasenevo, Biryulyovo, Maryino districts.The rapid industrial growth, the intensive construction of residential areas in the south, southwest and southeast of Moscow in the 1970s required additional generation of heat and electricity. The first capacities of CHPP-26 (hot water boiler PTVM-180) were put into operation on March 30, 1979. Construction was carried out in two stages: the first stage from 1979 to 1985, the second - from 1986 to 1998. In October 1998, CHPP-26 reached its design capacity. In 2009, the PT-80/100-130/13 turbine was reconstructed to increase the electrical capacity of power unit No. 1. This made it possible to increase the installed capacity of CHPP-26 to 1420 MW.In 2011, CHPP-26 commissioned a modern combined-cycle power unit No. 8 CCGT-420 with a record-breaking efficiency for the Russian electric power industry of up to 59% (in condensation mode). A consortium of the French company Alstom and the Russian EMAlliance conudcted the construction works. The electric capacity of the new power unit is 420.9 MW, and the thermal capacity is 228 Gcal.As part of Mosenergo's investment program, CHPP-26 is undergoing a full-scale reconstruction and modernization of equipment. At the outdoor switchgear (OSG) 220, 500 kV, all air circuit breakers were replaced with SF6 ones, protections were replaced with new, microprocessor ones. Current transformers and disconnectors were replaced at outdoor switchgear 220, 500 kV. To improve the reliability of the outdoor switchgear at CHPP-26, an AT-1 autotransformer was installed with the introduction of an automatic process control system for the electrical part. Work is underway to replace sections of steam pipelines and heating surfaces of power and hot water boilers. The work on reconstruction of the cooling towers at CHPP-26 is being carried out consistently. In 2013, the construction of indoor switchgear ZRU-10 kV No. 2 with a voltage of 10 kV and a capacity of 100 MW was completed. Work is underway to connect residential areas in the south of Moscow and in the Vidnovsky district of the Moscow region to a new closed switchgear.Hot water boilers PTVM-180 are equipped with burners for two-stage gas combustion, which reduce the output of nitrogen oxide by 20–30%. To reduce the noise impact on the environment, all power boilers were reconstructed with the installation of silencers in the flue gas ducts and the installation of silencers in the suction air ducts of the power boilers.[2]
