The 420MW power generation unit at Mosenergo, Moscow is being built on a turnkey EPC contract basis. The partnership agreement was signed in October 2005 between Alstom and EMAlliance. The combined heat and power plant is expected to start commercial operations in 2009. The plant is estimated to cost around €280m.

Contract awarded to Alstom

In December 2006, the contract was awarded to Alstom for its part in a turnkey delivery of a 420MW power generation unit. The contract was worth €170m, out of the total €280m.

Alstom, along with its Russian partner Power Engineering Group Energomachinostroitelny Alliance (EMAlliance), will work on the contract.

Integrated power solutions such as engineering, procurement, and commissioning of the unit will be provided by Alstom. It will supply components including multi –shaft combined cycle unit comprising a GT 26-gas turbine, steam turbine, two generators, one heat recovery steam generator and the control system for the entire facility.

“The plant will be installed with 280MW of gas turbine capacity, making it one of the first plants to have that capacity in Russia.”

A cooling tower, electrical equipment, heat exchanges and piping for the district heating system will be provided by EMAlliance. It would also manage civil works and construction work.

Alstom CEO and chairman Patrick Kron said: “Alstom is proud to help Russia meet its fast growing need for power with the most up-to-date combined cycle power generating technology. This turnkey project has no equivalent in the Russian power industry. It will produce electricity at a high efficiency rate, thus dramatically reducing CO2 emissions in comparison with other power plants.”

Mosenergo commences construction of PSU-420

In April 2007, Mosenergo commenced construction of steam power unit PSU-420 along with the construction of unit 8 PGU-420 CHP-26. The installed capacity of electric power is 420MW and of thermal power 265MW. With the new plant, efficiency of power at work in the condensation mode is expected to be of 59%. The plant will be installed with 280MW of gas turbine capacity, making it one of the first plants to have that capacity in Russia .

“Engineering, procurement, and commissioning of the unit will be provided by Alstom”

Mosenergo’s TPP-26 power plant is located in the ring of 220kV. Construction unit number 8 TPP is part of the implementation of development and technical re-equipment developed by the specialists from Mosenergo and scientists from Russian Academy Sciences.

Plant details

The gas turbine type is GT26. The mechanical draft water cooler is used for the cooling system. The fuel is natural gas with liquid fuel as back up.

Going by estimates made by Mosenergo, the cost of the project is RUB 10,833.33m with an investment of RUB 5,063.00m in made in 2008 and is expected to commission in the third quarter of 2009. It is expected that new unit 8 will increase the capacity at the plant to 1830MW. This project is part of Mosenergo’s programme of development for Moscow’s power network and will fulfil the power and heat needs within the region.

Background

The company is engaged in the construction of a new steam-and-gas combined cycle (SGCC) – technology-based power generating units at total energy plants (TEP) 21, 26 and 27. It implements technical upgradation of power plants using modern and efficient SGCC units.
