GE’s Power Services business, in consortium with NTPC GE Power Services Pvt Ltd (NGSL) and Gujarat State Electricity Corporation Ltd (GSECL), have announced the milestone results of a steam turbine modernization project at the Ukai power station in Gujarat. The project was completed on May 24, 2017, by utilizing GE’s latest modernization solutions, including its Advanced Steam Path (ASP) technology—part of the company’s Fleet360* portfolio, GE said in a recent release.
At Ukai, GE modernized the 200-mw BHEL-supplied, LMZ steam turbine (Unit 4) at the 1,350-mw Ukai power station, with its ASP technology. The ASP modernization features high-pressure and intermediate-pressure full module upgrades and a low-pressure inner block upgrade.
The retrofit will extend the unit’s life by 25 years, and it restored its output back to its original capacity of 200 mw. Final tests at Ukai’s plant displayed more efficient operations that will help the plant reduce its coal consumption by more than 140,000 tonnes per year and reduce carbon dioxide emissions by 180,000 tonnes per year, GE said.
This project is a first-of-its-kind shaftline retrofit for BHEL 200-mw -class units in India, and is aimed at increasing power, efficiency and reliability while also reducing emissions, GE noted.
Earlier this year, GE announced it would help NTPC Ltd, India’s largest utility, to modernize three 200-mw Ansaldo steam turbines with ASP technology at the Ramagundam power station in Telangana.
NTPC GE Power Services Pvt Ltd, formerly known as NTPC Alstom Power Services Pvt Ltd, is an equal joint venture between NTPC and GE.
