A Pioneer in Gas Turbine Technology

We leveraged more than 60 years of material science from our aviation heritage to get increased performance at high firing temperatures. We were the first to introduce single-crystal alloys and devoted 15 years to developing ceramic matrix composites. These materials provide longer parts life for lower lifecycle costs and higher efficiencies, leading to a cost effective conversion of fuel to electricity.

Additionally, GE is the industry leader in burning unconventional gas. We introduced the first F-class gas turbine to use Arabian Super Light crude. And we invented the Dry Low NOx (DLN) combustion system more than 30 years ago to reduce emissions.


Experience You Can Count On

GE is a power generation pioneer with a rich history and heritage that includes more than 60 years in gas turbine technology and manufacturing.

Half of the world’s installed power base is from GE, with more than 10,000 gas and steam turbine generating units, representing more than 1,000,000 megawatts of installed capacity in 120 countries.

Validation that Demonstrates Performance

We built the largest, most powerful off-grid gas turbine testing facility in the world that demonstrates proven gas turbine operability and performance, before first fire.
