Moscow City Power Plant II enters operation
In September 2007, JSC Technopromexport successfully commissioned the Moscow City Power Plant II.
This combined-cycle cogeneration plant, powered by two SGT-800 industrial gas turbines and one SST-700 industrial steam turbine from Siemens, will supply electricity and district heating to an entirely new section of the Russian capital.
In all, Siemens has sold 13 SGT-800 gas turbines to the Moscow area since 2001. The Moscow City Power Plant II turbines are the first to have been put into commercial operation, the plant having been built under a BOO (build-own-operate) scheme.
Together with a 30-MW SST-700 steam turbine and control system, the two 45-MW gas turbines form the heart of this combined cycle power plant which is now supplying a completely new city area with 121 megawatts (MW) of electricity and 92 megajoules per second (MJ/s) of district heating.
The new area, known as the Moscow International Business Center (MIBC) or, more familiarly, Moscow City, is a burgeoning city within a city, which combines everything from skyscraper office blocks to restaurants, retail outlets, parks, hotels and residences for half a million inhabitants. The area is accessible by road and underground transport from the rest of Moscow, and can now also boast its own power supply.
This is the second of two virtually identical power plants which Siemens has helped to build in Moscow City, but the first to be commissioned. The first contract was signed as early as 2001. Construction was discontinued in 2004 when the customer was declared bankrupt but a new commissioning date is now set for 2008. The second contract, for the newly commissioned Moscow City Power Plant II, was signed in November 2005. Siemens delivered its equipment between July and September 2006.
As well as providing the core equipment, Siemens had a monitoring and supervisory role in the project.
In September this year, the customer Technopromexport gave its formal approval of the supplied solution and the plant started generating power to the grid and heat to the district heating network, in good time for the winter. The one-year warranty period has now come into effect.
The latest order for Siemens SGT-800 gas turbines for the rapidly expanding Moscow area covers three gas turbine generator units to be used in the privately financed Kolomenskaya cogeneration project. The operator is replacing an outdated district heating plant with a modern cogeneration plant producing heat and power. The new plant is due to come into operation at the end of 2008.
The SGT-800, the largest in the Siemens industrial gas turbine power range, has recently been uprated to an output of 47MW.
