GE Power’s Gas Power Systems business has released a whitepaper that details the benefits of gas turbine technology for cleaner and safer operation. Co-authored by GE gas power technology experts John Ingham and Monamee Adhikari, the whitepaper presents the advantages of using aeroderivative turbines, including better quality grid firming, cleaner power with lower emissions, and cheaper power.

Whitepaper on gas turbine benefits released

Aeroderivative gas turbines yield excellent efficiencies from installation to maintenance making it an appropriate solution for faster, cheaper, cleaner and more stable power, the whitepaper states. They also offer a variety of fuel options which provide capability to harness fuels from different sources and to switch between fuels without shutting down.

The authors argue that aeroderivative gas turbines yield better efficiencies through rapid response to grid frequency fluctuations and combined cycle capability, resulting in better use of fuel. Lube oil consumption is 200 times lower when compared with reciprocating engines for example.

“Averaging 8 times less operational and maintenance manpower and over 15 times fewer maintenance events than reciprocating engines during a three-year cycle in an equivalent sized power plant, aeroderivatives require simpler maintenance. Their higher reliability and availability provide power in a few days after inspection which also lowers capital expenditure (CAPEX) costs per unit of generated power,” the whitepaper states.

“Aeroderivative gas turbines provide lower emissions and much smaller footprint therefore ensuring cleaner power and freeing land for other uses. They also allow for better integration of intermittent renewables to the grid, by providing a more stable grid through excellent frequency control.”

Elisee Sezan, CEO of GE’s Gas Power Systems business in sub-Saharan Africa, points out that aeroderivative gas turbines yield excellent efficiencies from installation to maintenance, making it an appropriate solution for faster, cheaper, cleaner and more stable power in Africa. GE’s first turbine in the region was commissioned in the early 1950s and the company achieved its 100th power plant installation in sub-Saharan Africa in 2018.

“Due to their small size and modular nature, aeroderivative gas turbines can be transported, installed and commissioned very quickly. With more than 100 million operating hours over the last 45 years and up to 44% simple cycle efficiency and 56% combined cycle efficiency with fast startup, high ramp rates and outstanding cycling capability, aeroderivatives provide flexible and reliable power generation,” the whitepaper concludes.
