Cheaper, cleaner, faster power

Derived from aviation technology, GE’s aeroderivative portfolio features turbines that provide cheaper power, a better-quality grid and cleaner power with lower emissions, when compared to reciprocating engines. They can also be installed quickly—in as little as a few weeks—to help alleviate frequent outages, making them especially well-suited for utility and industrial applications.

From higher efficiency and lower costs to faster, cleaner, higher quality power generation, aeroderivative gas turbines have many advantages over reciprocating engines. And we should know: GE has been in the aeroderivatives business for 50 years, with more than 150 million operating hours and more than 3000 units in operation.

Higher efficiency leads to lower costs

Lower lube oil costs
A highly efficient aeroderivative gas turbine in combined cycle like the LM2500 consumes only about 2 mL/MWh of lube oil per year—200 times less than a reciprocating engine. That can translate to a savings of more than $1 million per year for a 100 MW aeroderivative power plant.

Less maintenance
Aeroderivative gas turbines need maintenance only once a year, or when they have been in operation for 4,000 hours. Compared to high-speed reciprocating engines—which require 50 times more maintenance events per year—aeroderivative engines save more than 13,000 man hours over a 3-year maintenance cycle.


Plant availability and fuel flexibility

High availability
Aeroderivative gas turbines have the highest availability of any thermal power technology. An aeroderivative gas turbine can be replaced in a power plant, such as a utility or power plant, within a few days for a major inspection, which translates to higher availability—98.2% as compared to power generated by reciprocating engines, which average 93% availability.

Diverse fuel options
With the ability to operate on a wide spectrum of fuels—including natural gas, LPG (propane and butane), isopentane, ethanol, diesel, and Coke Oven gas—aeroderivative gas turbines can allow power customers to switch between fuels to save money, all without stopping, and without a reduction in power. Using diverse fuel sources doesn’t just increase reliability, it also results in significant fuel savings—from $12 million up to $43 million per year—as compared to the fuel costs of a high-speed reciprocating engine.*

Getting power to the grid, wherever it’s needed

Fast installation
Because they are small and modular, aeroderivative engines can be transported, installed and commissioned in as little as 3 months, as compared to 12-18 months for reciprocating engines. They can be installed outdoors with minimal foundation requirements, making them an advantageous energy solution for any region across Africa that needs fast, clean, reliable power.

Fast response rate
GE’s aeroderivative gas turbines feature a power turbine and high-pressure shaft that work together to respond quickly to grid frequency fluctuations, helping create a more stable and reliable grid than that of reciprocating engines.


Smaller and more stable

Lower emissions
Equipped with best-in-class combustion systems, aeroderivative gas turbines can offer 15 or 25 ppm NOx without needing SCRs (selective catalytic reduction) or the use of ammonia.

Enabling renewables
Aeroderivative gas turbines allow renewables to operate when needed, saving fuel and maintenance—and maintaining a stable grid to allow the integration of more renewables in the future.

Smaller footprint
Because they have about 22 times more power output per unit than comparable high-speed diesel reciprocating engines, GE’s aeroderivative gas power plants take up less space—a real advantage where real estate is expensive. *
