On December 22nd, 2010 Technopromexport (TPE) put into commercial operation the second power unit at the Kaliningrad thermal power station-2. Following successful trials of the PGU-450 power unit, Valery Ilyushin, Deputy General Director at Technopromexport and Oleg Gurylev, General Director of Inter RAO UES signed a certificate to confirm that the new unit is in operation and that Technopromexport had completed the contract within the allotted 24 month time frame. As a result of the new power unit, output at the Kalingradskaya TPP-2 has been doubled and has reached 900 МW of electricity and 680 Gcalories of thermal output.
With these two new units, the power supply problem for the Kalingrad area will shortly be completely solved. Power is delivered to Yantarenergo grid by high voltage transmission lines and substations supplying 330 KwH to the Central and Northern zones and 110KwH to the Leningrad & Right Bank zones. The contract for construction of the power station was signed in December 2008 after Technopromexport won the open tender for the project. Our long term experience in this area was a major factor in our success in gaining this project.
Experts at TPE have also constructed two 450MW power units for the North-West CCPP in St. Petersburg, 2 x power units at the Ivanovskaya CCGT, a unit at the Mezhdunarodnaya CCPP in Moscow with a 120 MW capacity, delivered the gas turbines for the Sochinskya TPP and completed construction on 10 mobile GTES in the Moscow region to deal with peak time demand.
We are also currently involved in a turnkey project to supply a PGU 450MWt to the Urengoyskaya HPP, one for the Yuzhnaya TPP thermal power plant in St Petersburg and a PGU 230 to Sisak in Croatia.
Moving back to Kalingrad, we have also been contracted to construct the main and auxiliary buildings, delivery, and installation of the equipment, start up and adjustment works and the training of personnel. The second power unit at the Kaliningradskaya TPP-2 was designed on the basis of modern vapor gas technology with the gas turbines exhaust gas being used in disposal boilers, providing efficient Cogeneration.
Overall, roughly 60 million cubic feet of natural gas will be used annually. The PGU-450 KTETS-2 consists of two JOSC Power Machines gas turbines (GTE-160) ; one steam turbine (T-150-7,7) of the same manufacturer, three JSC “Electrosila” turbine generators (ТZFG-160-2UZ) and JSC “ Podolskiy Mashinostroitelniy zavod” two P-96 disposal boilers, manufactured by JSC “Zaporozhtransformator”, three transformers (TDTS-200000/110U1) and three (TDTs-250000/330У1), manufactured by the same company.
The power unit economic and technical features are as follows:
» Average annual operating fuel ratio of 76%;
» Efficiency (gross) in condensation mode of 51%;
» Electric power consumption by the plant of 2,22%
» The average annual specific expenditure of conditional fuel for the released thermal energy of 155,0 kg/Cal.
In comparison with the PGU-450, the first North-West CCPP in St. Petersburg Russia and the construction of second power unit of Kaliningradskaya TPP-2 there are some technological changes in terms of construction that have been applied. For example, the first PGU was built with horizontal disposal boilers of open configuration. The second, because of differing environmental and soil conditions, the turbine equipment, unlike that at the North-West CCPP, is located on a vibration protected support.
On the third (2nd power unit at KTETS-2), an updated automatic regulation system was used. Technopromexport has also guaranteed the 2nd PGU at Kaliningrad for 2 years, as per the terms of the contract.
In conclusion, this project will provide energy independence and safety to the region and the implementation of these PGU’s has solved the electricity supply problem in the Kaliningrad region for the long term.
