Mexican Gas-Fired Turbines show Efficiency rise after Upgrade

A newly upgraded gas-fired turbine in Mexico has achieved an output increase of 9.2 percent and 2.9 percent efficiency improvement, GE Power Services reported in a Wednesday release detailing its work on turbines made by another company.

The cross-fleet gas turbine upgrade project was at the Fuerza y Energía de Tuxpan facility in Veracruz, Mexico. Tuxpan is owned by Global Power Generation (GPG), the international power generation subsidiary of Naturgy and the Kuwait Investment Authority.

GE applied its cross-fleet technologies to two Mitsubishi Heavy Industries, Ltd. M501F gas turbines and two steam turbines.

 “At GPG, we provide service to more than 1.5 million people, and we are continuously looking for ways to improve the availability and efficiency of our operations to better serve our customers,” said Fernando Ramos, chief operating officer of GPG, in a statement. “GE’s cross-fleet upgrade for our M501F machines achieved better results than they promised, allowing us to realize greater value from our equipment and improve our plant performance. Having a services provider like GE that can address plant-level improvements is important. One of our biggest concerns when upgrading a gas turbine is ensuring the rest of the plant can support any changes in performance.”

The work is part of a 12-year agreement with GE. Over the past 20 months, GE has maintained and service gas turbines at three power plants as part of the deal with GPG.

 “This has been a terrific partnership with GPG over the last two years,” said Scott Strazik, president and CEO of GE’s Power Services business. “We’re proud of the work we did at Tuxpan, where we were able to demonstrate our ability to service gas turbines manufactured by other original equipment manufacturers (OEMs). But cross-fleet isn’t just about servicing non-GE machines. It’s about adopting them and making them our own—by applying our technologies and expertise from the world’s largest installed base over their life cycle.”

GPG was set up in 2014 by Naturgy and Kuwait Investment Authority KIA—through its subsidiary Wren House Infrastructure—as a vehicle to channel its international electricity generation business. In Mexico, Global Power Generation operates four combined cycle Power Plants, two in the state of Sonora, one in Veracruz; and another in Durango.
