The global market for diesel generators is expected to grow from $22.2 billion in 2025 and is projected to reach $31.8 billion by the end of 2030, at a compound annual growth rate (CAGR) of 7.5% during the forecast period of 2025 to 2030.
The growing demand for more sustainable and clean sources of reliable electricity has spurred technological advances in diesel engines and gensets. Environmental and energy security concerns are driving the push for gensets with higher power output, quieter operation and cleaner emissions. Due to their cost-effectiveness and efficient resource use, hybrid power systems are gaining popularity. By reducing fuel consumption and maintenance costs, battery energy storage systems that optimize diesel gensets improve overall productivity.
Remote monitoring, improved fuel efficiency and reduced risk of engine breakdowns are enabled by integrating technology such as predictive maintenance, electronic control systems and advanced data analytics into diesel gensets. Smart diesel gensets facilitate effective combustion, operational control and load distribution through digital technologies. In addition to aligning with governments’ increased focus on environmental regulations and emissions control, advances in fuel system efficiency, engine modifications, emissions treatments and digital controls are poised to enhance overall engine performance, increase energy efficiency and improve fuel economy.
The report covers qualitative and quantitative information for diesel generator set (genset) market segments, such as power ratings, applications and end users. The study also analyzes the diesel generator market in four regions: the Americas, Europe, Asia-Pacific (APAC), and the Middle East and Africa (MEA). It covers emerging technologies, recent developments, patents and companies’ environmental, social and governance (ESG) initiatives. Macroeconomic factors have been evaluated, including U.S. tariffs and the impact of raw materials prices. In addition, the market shares of the leading companies and their strategies are analyzed. All market values are in U.S. dollars ($ millions).
