Mitsubishi Heavy Industries (MHI) has won a contract from Daewoo International to supply two sets of an M701F4 gas turbine and generator for the Talimarjan power plant expansion project in Qashqadaryo Province, Uzbekistan.
Uzbekenergo's expansion project will feature two 450MW new gas turbine combined-cycle (GTCC) power generation plants at its existing Talimarjan plant. The project is likely to become operational by 2016. Uzbekenergo solicited bids for the expansion project in March 2012.
The MHI sets will be installed at the two GTCC power plants. MHI and Mitsubishi Electric will provide gas turbines and generators, while Hyundai Engineering & Construction has been selected as the engineering, procurement and construction contractor for the project.
Once operational, the expansion project is likely to increase thermal power generation from 4.6 billion kWh to 10.4 billion kWh.
Each of the two GTCC power plants at the expansion project will feature a 320MW class M701F4 gas turbine, steam turbine, heat recovery steam generator and generator.
Typical GTCC power plants, in which gas and steam turbines are used in combination, generate electricity in two stages by using high-temperature exhaust gas from the gas turbine, and hence attain higher thermal efficiency than non-GTCC plants.
The expansion project is being financed by the Japanese International Cooperation Agency ($300m), the Asian Development Bank ($350m) and the Uzbekistan Fund for Reconstruction and Development ($250m).
In addition, the World Bank provided $110m in loans for the Talimarjan transmission project, for the construction of a 500 / 220kV new substation, a 218km 500kV single circuit transmission line from Talimarjan to the Sogdiana substation and a bay extension at the Sogdiana substation.
