The global diesel generator market size was USD 12.98 billion in 2019 and is anticipated to reach USD 16.85 billion by 2027, exhibiting a CAGR of 5.5% during the forecast period.

The diesel generator (DG) technology is a long-standing method that is used to produce energy by utilizing fossil fuel to serve emergency power needs. The product is widely used to deliver electric energy by converting chemical energy using various equipment such as AC alternator, control panel, fuel tank, radiator, engine, and many more. DG sets are commonly installed to power hospitals, homes, schools, factories, construction sites, among other verticals, either as the primary or as a backup power source in case of grid failures.

Shut Downs in Industrial Operations During the COVID-19 Weakens Potential for Diesel Generator Installations

The ongoing coronavirus pandemic has compelled governments to implement nation-wide or state-wide lockdowns to contain the viral infection. Consequently, this market is set to observe a decreasing revenue share in 2020 owing to the aftermath of this global crisis. The obstruction in the commencement of new end-user projects owing to the unattainability of required capital has significantly narrowed the integration of new systems. The disruption of daily business along with disturbances in heavy-duty processes such as construction activities, mining of new assets, hydrocarbon exploration & production, fabrication of new commercial substructures, and others have led to an unprecedented decrease in product demand.
