The diesel generator set (genset) market designates the use of internal combustion engines for distributed power production. Today, reciprocating engine-based gensets are among the fastest-selling, least expensive distributed generation (DG) technologies in the world. As a source of emergency standby, prime, or continuous power, diesel-fueled gensets are poised for continued growth in most regions and power classes, but face increasing competition from natural gas generators in certain markets. The number of specialized segments within the genset market spanning power classes, applications, and end-use customers offers a rich ecosystem of opportunities for market participants. As a whole, the market has experienced steady growth. However, continued growth in the supply of unconventional gas resources and tightening regulations targeting stationary generator emissions may signal a shift toward cleaner-burning natural gas systems over their diesel counterparts. In the short term, though, countries with strong economic and/or population growth rates that are increasingly burdened by unreliable power grid infrastructure and blackouts will continue to drive diesel genset sales. According to Navigant Research, global diesel genset capacity additions are expected to increase from 62.5 GW in 2015 to 103.7 GW in 2024. This Navigant Research report analyzes the global market potential for diesel gensets for residential, commercial, industrial, and power plant applications. The study includes assessments of global regions for capacity installations, an analysis of market drivers and barriers, and a comparison of diesel and natural gas gensets. Global market forecasts for annual capacity additions and revenue, segmented by country and region, extend through 2024. The report also examines the key technologies and components related to diesel gensets, as well as the competitive landscape.
