Alstom and NASL have been awarded a contract worth nearly $29 million by Gujarat State Electricity Corp. to renovate and modernize two coal-fired power turbines at the Ukai and Wanakbori thermal power plants, both situated in Gujarat, India.

Alstom will perform full shaftline retrofits of the 200 MW BHEL-supplied LMZ design steam turbines at unit 4 of the 1,350 MW Ukai power station and unit 3 of the 1,470 MW Wanakbori power station.

The retrofits will increase turbine efficiency by around 14 percent from existing operating conditions thereby reducing coal consumption and CO2 emissions. The scope of each project includes engineering, supply, erection, commissioning and testing. Equipment will be manufactured at Alstom’s facilities in India and Poland. The projects are scheduled to be commissioned in 2017.

There are more than 50 similar, BHEL-supplied LMZ design, 200/210MW steam turbine units in India that can benefit from modernisation. Such projects contribute to India achieving its goals under the “National Mission on Enhanced Energy Efficiency.”
