Benefits
A flange-to-flange solution includes a full replacement of an existing gas turbine core engine with a new production engine. Implementing a flange-to-flange solution brings all the technical advancements and reliability of a new unit within the time frame of an outage. In some cases there will be additional options, including Dry Low NOx (DLN) combustion system, dual fuel and alternative fuel capability, piping and auxiliaries, inlet filter house, inlet and exhaust plenums, motor control center (MCC), Mark VIe integrated control system, and select OpFlex solutions.
Improves reliability and extends maintenance intervals
Expands flexibility to operate in peak and cyclic environments
Lowers fuel costs through reduced heat rate
Lowers maintenance costs and extends asset/plant life
Recaptures lost performance with output increase
Reduces emissions
Alleviates rotor end-of-life concerns
Repowering your gas turbine involves a full (or flange-to-flange) replacement of an existing gas turbine engine, giving you all the benefits of today’s technology and engineering innovation within the footprint of your existing asset. Our proficiency in flange-to-flange repowering (including plant integration) solutions for heavy-duty, aeroderivative (aero), and industrial gas turbines from different OEMs–including Siemens, Westinghouse, Pratt & Whitney and Rolls-Royce–will position your plant to be competitive in the future.
Why repower?
With more renewable energy sources being added to the global grid, power plants need to operate in an increasingly flexible manner while reducing operating costs and maintaining emissions limits. This is a challenge for aging fleets nearing the end of their operating life. Repowering your gas turbine allows you to upgrade to a more advanced turbine technology that fits within the same footprint as the old one. This can increase plant life by many years and make better use of your balance-of-plant assets—while improving output, efficiency, and availability. And a repowering can typically be done within the average time of an outage, or as little as 15 days.

“Replacing the existing gas turbines at the Penal Power Station with GE’s upgraded units will improve our generation efficiency and add value in terms of greater availability by establishing longer intervals between scheduled maintenance outages.”
Fitzroy Harewood
General Manager, PowerGen Ltd.
After 30 years, Penal Power Station’s gas turbines, rotors and other components were close to the end of their running life. To help avoid new maintenance costs, the Power Generation Company of Trinidad and Tobago Limited (PowerGen Ltd.) needed to replace its two existing 7E turbines. GE integrated two new 7E gas turbine units that run on natural gas for PowerGen Ltd. The turbines will potentially improve the heat rate of the plant by 2.25% as well as add 25 – 30 years of life to the site.
output increase
potential annual fuel savings
In an industry characterized by constant change and technological advances, an industrial chemical facility in Asia needed to find a way to improve production levels. To increase efficiency and output while reducing emissions, GE’s new 6B repowering technology will be utilized on three 6B units. The output increase of 25% is expected to help the customer accelerate the rate of chemical production and could lead to significant fuel savings.

“As the sole distributor of electricity in Jamaica, we see the use of LNG as resulting in greater stability in the price of electricity for our customers. By replacing a 19-year old unit with GE's advanced aeroderivative technology, we’ll be able to deliver more efficient power to our people, our businesses, and our critical facilities.”
Joseph Williams
Senior Vice President of Generation, JPS
With half of its infrastructure over 30-years old, Jamaica is seeking to modernize its power plants and cut its oil dependency with a diversified energy mix. And, rising connectivity on the island has JPS in need of more capacity for its power stations. Integrating the LM2500+ gas turbine, GE Power Services signed an agreement with JPS to modernize its generation equipment and provide expert advisement at its Bogue Power Station in Montego Bay.
