GE’s Power Services business, in consortium with NGSL has completed steam turbine modernization at the 1,350MW Ukai coal-fired power station in the Indian state of Gujarat.
NGSL is a 50-50 joint venture of India's energy conglomerate NTPC and GE.
As part of the modernization work, GE has upgraded the 200MW LMZ steam turbine (unit 4) at the Gujarat State Electricity Corporation’s (GSECL) Ukai power plant.
The unit, which was built by Bharat Heavy Electricals (BHEL), has been upgraded with GE’s Advanced Steam Path (ASP) technology.
The ASP modernization included high-pressure and intermediate-pressure full module upgrades and a low-pressure inner block upgrade.
GE said that the modernization project has extended the operational life of the unit by 25 years in addition to restoring the original capacity of 200MW. It also improved the unit’s heat rate by approximately 14.5%.
GSECL managing director Pradip Dahake said: “GE’s solutions enabled us to better position our operations to meet not only expected increases in demand, but also future, potential, emissions requirements.”
GE noted that the modernizations at Ukai power station also increased overall efficiency of the power plant by 5.5%. It is also expected to reduce coal consumption by 140,000 tons per annum.
GE’s Power Services business senior executive in charge of steam plant solutions Ashok Ganesan said: “By combining our cross-fleet capabilities with our Powering Efficiency COE’s commitment to boost efficiency and reduce emissions of coal-fired power plants, we provide our customers with the tools they need to modernize the world’s installed steam turbine fleet to meet future energy challenges.”
The upgrade work is a part of GSECL’s effort to help Gujarat meet future energy needs and also contributes to the country’s goal to reduce CO2 emissions from its installed coal-fired power plants.
