France’s Alstom has commissioned unit 8 of the TPP-26 cogeneration gas combined-cycle power plant in Moscow, Russia, on behalf of its client OJSC Mosenergo, a subsidiary of energy major Gazprom.

With an efficiency of 59%, the gas-fired cogeneration combined-cycle unit will have the highest efficiency of any combined cycle power plant in Russia, says Alstom, while the use of surplus steam for district heating will bring the plant’s overall fuel use to well over 85%.

The integration of unit 8, designed to produce 420MW of electrical power and up to 265MW of district heating, will bring total plant output up to 1830 MW, making the TPP-26 plant a major contributor to the Russian grid, as well as a valuable source of district heating.

Mosenergo commissioned Alstom to build a combined cycle plant in Russia on an EPC basis in 2007, making it Russia’s first turnkey energy project to be awarded to a non-Russian company.
