THE ENERGY CHALLENGE

Providing uninterrupted electricity across the continent

The demand for energy in Africa is expected to increase by more than 4% per year through 2040. Closing this energy gap while adding power to the African grid is a challenge for most countries in the region, which currently rely on a combination of hydroelectric power and diesel-fueled generation. With limited access to gas, Africaneeds faster, cleaner, more reliable and cost-effective power. Compared to reciprocating engines, GE’s aeroderivative gas turbines are an efficient, fuel-flexible solution for adding power to the grid—and keeping the lights on for the region’s more than 1 billion inhabitants.

THE AERO ADVANTAGE

Cheaper, cleaner, faster power

Derived from aviation technology, GE’s aeroderivative portfolio features highly flexible and mobile technologies for use in a wide variety of applications. Compared to reciprocating engines, aeroderivative turbines provide cheaper power, a better-quality grid and cleaner power with lower emissions. 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 throughout Africa.

The benefits of aeroderivative gas turbines vs. reciprocating engines

From higher efficiency and lower costs to faster, cleaner, higher quality power generation, aeroderivative gas turbines have many benefits 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.

CHEAPER POWER

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.

HIGH QUALITY POWER

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 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 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.*

*Fuel savings range based on a natural gas price of $1–4/MMBTU and a diesel gas price of $6–12/MMBTU.

FASTER POWER

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 effective 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 ensure a more stable and reliable grid – vital for the energy challenges in Africa.

CLEANER POWER

Smaller and more stable

Lower emissions
Equipped with best-in-class combustion systems, aeroderivatives 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. *
