In August 2018, modernization program of operating power unit of Yerevan Thermal Power Plant to begin

ArmInfo. In August 2018, the  program of modernization of the operating power unit of Yerevan TPP  will begin in Armenia.

According to the press service of the Ministry of Energy  Infrastructures and Natural Resources of the Republic of Armenia, the  project will increase the efficiency of the station. In particular,  the specific weight of gas for electricity production will decrease,  and the unit's capacity will also increase. In particular, as a  result of technical modernization, the capacity of the unit from the  current 220 MW will reach 227 MW, the conditional fuel consumption  from 258.1 g / kWh will decrease to 252.8 grams / kWh, and the  efficiency will increase by 1%. At the same time, the volume of  electricity production will increase by 59.5 million kWh, which, in  terms of the current tariff, will be more than 1.2 billion drams.  After technical modernization, the plant's overhaul periods will last  for 2 years - from the current four years to six years.

Earlier Arkadi Gevorgyan, technical director of Yerevan TPP CJSC,  informed ArmInfo that in the current year, along with major repair  works, it is planned to modernize the gas turbine unit, as a result  of which the unit's capacity will increase by 7 MW, and the  efficiency will increase by 1%. At the moment, the installed capacity  of the gas turbine plant is 180 MW, and the gas turbine plant - 63.6  MW. The total capacity of the unit is 243 MW, and the efficiency is  50%. "When working in the heating system, that is, when the  consumption of heat energy starts in Armenia, the efficiency of the  block will be 73%, which is a very high index," Arkady Gevorgyan  said. He noted that the unit has the capacity to produce heat energy  of 580 Gigajoules. The unit with a capacity of 242 MW with a gas  turbine unit was put into operation in April 2010. The project was  implemented on a loan from the Japan Bank for International  Cooperation (JBIC) to 26.4 billion Japanese yen (about $ 280  million). The Yerevan CHP 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  PPR 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. PPR is held every 36 thousand hours of work of the station.
