The global variable speed generator market would likely grow at a CAGR of 6.20% during 2025-2034. Asia, North America and Europe are likely to be key markets.
Global Market Likely to be Driven by Need for Solutions that Enable Fuel Savings and Offer Superior Performance
In FC concept, the entire power generated passes through a full-size converter which offers full variable speed operation with improved grid code compliance. Benefits include full speed range, advanced grid compliance, and separation of drive train from grid disturbances.
Variable Speed Diesel Generators (VSDGs) enable diesel engine operation at optimal speed according to the electrical load but need extra electrical equipment and regulation to maintain power output to electrical standards.
Variable speed technology enables regulation and adjustment of engine speed in accordance with connected load, making it more cost-effective to operate. As compared to conventional, constant speed units, variable units provide many advantages, including up to fifteen percent reduction in fuel consumption; up to twenty percent increase in time between overhauls; lesser noise emissions; and more power density with less installation space. Variable speed units are especially useful in running modes with a high proportion of low loads. Such advantages are expected to drive the global variable speed generator market.
Atlas Copco offers QAS 60/35 VSG Variable Speed Generator, which offers operational savings, and better performance and reliability. It removes inherent risks linked with low-load generator operation, like bore polishing, cylinder glazing, high oil consumption, heavy carbon build-up, fuel waste, and low combustion temperatures. Such solutions are expected to boost the global variable speed generator market.
In 2022, Volvo Penta launched a new series of variable-speed generator sets for marine vessels. The generator sets were intended to serve as a ‘key enabler’ for electric propulsion for marine ships.
