ArmInfo.The launch of the modernization program for the Yerevan Electric Power Station was launched, ArmInfo was told in the Ministry of Energy and Natural Resources of Armenia. The modernization program will be implemented within six months, its cost is 18.8 million euros, and the contractor is the American General Electric.
According to the ministry, the project envisages the reconstruction of a gas turbine, including an air compressor of the MXL-2 class. As a result, the plant's capacity will increase by about 7 MW from 220 to 227 MW, the specific fuel consumption will decrease from 258.1 pounds per square inch / kWh to 252.8 pounds per square inch / kWh. The power supply will be upgraded. The efficiency of the power unit will increase by 1%, the electricity production will increase to 59.5 million kWh.
After the technical update, the frequency of the overhaul of the unit will decrease from 4 to 6 years, which will help to increase the period of continuous operation of the power unit.
Previously, Arkadi Gevorgyan, technical director of Yerevan TPP CJSC, informed ArmInfo that when operating in the heating system, that is, when the heat energy consumption starts in Armenia, the efficiency of the block will be 73%, which is a very high indicator. Gevorgyan noted that the unit has the possibility of producing heat energy of 580 Gig joules.
The gas turbine power unit with the combined cycle of the Yerevan TPP was built on a loan provided by the Japanese state bank for international cooperation (JBIC) and was put into commercial operation in April 2010. The rated power of the unit is 243 MW, the thermal power is about 434 GJ / h.
The Yerevan HPP is a customer of Iranian natural gas, which is supplied to Armenia in exchange for electricity at a rate of 3 kWh per 1 cubic meter of gas. The last time the block was stopped at the PWP in June 2014. Then the cost of overhaul amounted to 9.5 billion drams, 90% of which were used to purchase spare parts for the gas turbine. PWP is held every 36 thousand hours of work of the station.
