A heritage of quality
GE was proud to celebrate the 30-year anniversary of the 7F gas turbine in 2019. The 7F technology is core to GE Gas Power's portfolio of products and services. Its installed base of approximately 950 units is a testament to the engine’s success and customers’ trust to partner with GE to achieve high performance and operational reliability.
In terms of fuel flexibility, the 7F.04 gas turbine is the only turbine in its class to burn Arabian Super Light (ASL), 15% C2, +20/-10% Modified Wobbe Index (MWI).
A simple-cycle 7F.05 gas turbine can reliably produce 200 MW within 10 minutes, and can reach full load in under 11 minutes. A 7F.05 can also balance renewables by load-following at 40 MW/min ramp rates while maintaining emissions compliance.
The 7F.05’s improved maintenance practices, combined with features like field removal compressor airfoils means it can reduce replacement time, downtime, and costs.
The 7F.04 features an enhanced compressor and hot gas path cooling and sealing technologies, improving both performance and durability.
GE’s F-class gas turbines were among the first to achieve 50 million operating hours, 1 million starts, single-digit NOx emissions, a firing temperature greater than 2,400˚F, and operation with Arabian Super Light (ASL) as a fuel.
We are at a pivotal time in the power industry, where technology advancements intersect with the pressing challenges of load growth, extreme weather normalcy, and grid stability. Discover insights into the last decade of industry changes and their impacts on the 7F combustion turbine fleet.

Leveraging decades of expertise and dedication
GE Gas Power and Maxim Power worked together to install and upgrade a 7F gas turbine in a year-round project that helped support Canada’s coal-to-gas transition. For this project, GE provided relocation support with a DLN2.6+ upgrade and secured a contractual services agreement for the GE 7F.05 gas turbine.

reduction in emissions from coal to natural gas
"GE helped us solve our most pressing power generation challenges, such as the upgrade and maintenance of a GE gas turbine that we purchased from a third party and sat in storage, unused, for eight years near a copper mine in the Northern part of the United States. We know that GE has the level of experience needed to deliver reliable and sustainable power under any condition."

President and Chief Operating Officer, Maxim Power
Just in time for the 7F gas turbine’s 30th anniversary, GE Gas Power announced a new plant in Mexico coming online, ready to meet the country’s growing electricity needs. The 907 MW Norte III combined cycle power plant uses four GE 7F.04 gas turbines and will be operated and maintained by GE for the next 25 years.
