• GE’s Advanced Steam Path (ASP) Solution Restored Original Output of BHEL Steam Turbine, Improved Its Heat Rate by Approximately 14.5 Percent and Extended Unit Life up to 25 Years
First-of-Its-Kind Shaftline Retrofit in India on BHEL 200-Megawatt Class Fleet;
• Modernizations at Gujarat State Electricity Corporation Limited’s (GSECL’s) Ukai Power Station Increased Overall Power Plant Efficiency by 5.5 Percentage Points and Are Expected to Reduce Coal Consumption by 140,000 Tons per Year;
• GE’s Fleet360• Total Plant Services Solutions Position GSECL to Help Meet Gujarat’s Future Energy Needs While Reducing Emissions.
Aligning with India’s goal to improve the efficiency and reduce emissions of the country’s installed fleet of coal-fired power plants, GE’s Power Services business, in consortium with NGSL (50:50 joint venture of NTPC and GE) and Gujarat State Electricity Corporation Limited (GSECL), today announced the milestone results of a steam turbine modernization project at the Ukai power station in the state of 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
“Power generation efficiency and emissions are widely discussed topics around the world and will play a critical role, especially in existing coal fleets, in how we work to meet future energy demands and challenges on a global scale,” said Mr. Pradip Dahake, managing director, GSECL. “India is no exception. When it came time for us to modernize some of our generation equipment, it was GE’s cross-fleet service capabilities that gave us the efficiency and emissions improvements we were looking for. GE’s solutions enabled us to better position our operations to meet not only expected increases in demand, but also future, potential, emissions requirements.”
At Ukai, GE modernized the 200-megawatt (MW) Bharat Heavy Electricals Limited (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 tons per year and reduce carbon dioxide emissions by 180,000 tons per year. The emissions reduction will provide environmental benefits equal to the amount of carbon dioxide (CO2) absorbed by approximately 732 square kilometers of forest per year (an area 35 percent bigger than the Corbett National Park) or equivalent to 162,000 Indian cars being taken off the road. In addition, reducing coal consumption will result in approximately US$7 million savings for the utility every year.
Upgrading Ukai is a milestone project for GE’s Powering Efficiency Center of Excellence (COE), which aims to slash global CO2 emissions from the world’s fleet of existing coal plants through a total plant hardware and software solution approach.
“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,” said Ashok Ganesan, senior executive in charge of steam plant solutions for GE’s Power Services business and the global COE leader.
“With GE’s acquisition of Alstom’s power business back in 2015, we added significant technologies and capabilities to help modernize coal-fired power plants,” Ganesan continued. “We offer power producers added value with our Fleet360 portfolio, and we have comprehensive capabilities to service and upgrade not only our own equipment, but also that of more than 90 other original equipment manufacturers.”
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. Earlier this year, GE announced it would help NTPC Limited, India’s largest utility, to modernize three 200-MW Ansaldo steam turbines with ASP technology at the Ramagundam station. The upgrades will increase turbine output and improve efficiency and flexibility. Upgrade projects like these will better position the country to meet future energy demands and challenges including backing up renewables in the New Policies Scenario, electricity demand will more than triple in the next two decades, rising by 4.9 percent per year on average from 900 terawatt-hours (TWh) in 2013 to almost 3,300 TWh by the end of 2040.
