Reciprocating engine-based gensets are among the fastest-selling, least expensive distributed generation (DG) technologies in the world, according to a new report from US-based Navigant.

As a source of emergency standby, prime, or continuous power, diesel-fuelled gensets are poised for continued growth in most regions and power classes, but face increasing competition from natural gas generators in certain markets, the report concludes.

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.
