96. The Benefits of Mobile Aero-derivative Gas Turbines for Power Generation

If you’ve flown on a commercial airplane, you’ve likely sat within a hundred feet of an operating gas turbine engine. Gas turbines have been used to power aircraft since the 1940s. But gas turbines like those on airplanes are also used for generating electricity. These designs are known as aero-derivative gas turbines and occupy a special place in the power market. Aero-derivative gas turbines are popular because of their reliability, efficiency, and flexibility. They are significantly lighter, respond faster, and have a smaller footprint than their heavy-duty counterparts, which makes them much easier to utilize for temporary purposes and in applications that require mobility. “If you look at the high-level goal for the industry in terms of decarbonization, grid resilience, resource adequacy, and affordability, the aero-derivatives fit perfectly in all those categories,” Harsh Shah, vice president of sales and business development with Mitsubishi Power Aero, said as a guest on The POWER Podcast. “We provide solutions that generate power from 30 MW to 140 MW, and we see a very strong demand for these products across the globe—everywhere—in developed nations, developing nations, whether it’s industrial, utilities, independent power producers, and even captive power producers.” Shah said the main reason for the demand is that when customers require fast-track power solutions, and can’t wait years between signing a contract and having the power come online, aero-derivatives are often the best option. “When time is an important factor, the aero-derivative solution is very important,” he said. Shah offered a recent example to demonstrate how quickly aero-derivative gas turbines can be deployed. Mitsubishi Power Aero (previously PW Power Systems, the company underwent a rebranding on April 1) worked with Mexico’s state-owned power utility, Comisión Federal de Electricidad (CFE), to add 150 MW of generation to help meet summer demand in the Mexicali, Baja California region. Negotiations began in January this year, and
