GE, NGSL Increase Steam Turbines Efficiency of NTPC’s Ramagundam Power Plant

GE Power India Ltd (GEPIL) and its affiliates in consortium with NGSL achieved milestone results from its steam turbine renovation and modernization project at NTPC’s Ramagundam, Super Thermal Power Station, 3X200 MW unit 1&3, completed in 2021 and 2022, respectively.
 
The steam turbine upgrade project supported NTPC’s Ramagundam Power Plant Unit 1&3 with average -9.9 per cent improvement in turbine heat rate, turbine life extension by 20 years and average +3.8 per cent points improvement in thermal efficiency of both the units.
 
Moreover, the upgraded units will support 2.12 lakhs Metric Ton/year potential annual savings in coal consumption for the power plant. Also, the project reduces 2.34 lakhs Metric Ton/year CO2 emissions for the area.
 
This is first of NTPC’s energy efficient steam turbine project carried out and the team was able to deliver better than the agreed contractual commitments on output and performance, setting a new best-in-class performance benchmark for the heat rate for these units. Following the success of units 1&3, the team is now gearing up for installation and commissioning of unit 2.
 
The combined additional 20 MW output generated from both units will provide electricity to approximately 44,100 Indian houses. The reduction in CO2 emissions is equivalent to *141,200 cars taken off the roads.
 
Commenting on the achievement, Prashant Jain, RGM - GE Steam Power and MD - GE Power India Ltd said, “I am very proud of the team who delivered over and above the agreed results to the customer. This project supports the decarbonization story of India with solutions aided by more efficient and flexible power generation solutions. Upgrade projects like these are aimed at increasing power, efficiency and reliability while also reducing emissions and will better position the country to meet future energy demands”.
 
Supporting the Government’s ‘Make in India’ initiative, some parts of the project requirements were fulfilled locally from India, including LP turbine manufacturing, and supply by the GE facility in Sanand, Gujarat and sourcing of critical auxiliary components from various vendors within the country.
