Diesel generator is the equipment used to generate electricity from the mechanical energy, which is obtained from combustion of diesel or biodiesel. Diesel generator is equipped with an internal combustion engine, electric generator, mechanical coupling, voltage regulator, and speed regulator. This generator finds its application across various end-use industries such as in building & public infrastructure, data centers, transportation & logistic, and commercial infrastructures.

Global diesel generator market size was valued at $20.8 billion in 2019, and is projected to reach $37.1 billion by 2027, growing at a CAGR of 9.8% from 2020 to 2027.

Significant development of the end-use industries such as oil & gas, telecom, mining, and healthcare is fueling the growth of the diesel generator market. In addition, increase in demand for diesel generator as a source of backup power from developing economies is driving the growth of the market, globally. However, implementation of stringent government regulations toward environmental pollution from diesel generators and rapid development of the renewable energy sector are the key factors hampering the growth of the global market in the upcoming years.

Depending on the type, large diesel generator segment held the highest market share of about 57.05% in 2019, and is expected to maintain its dominance during the forecast period. This is owing to increase in demand from large-scale industries such as mining, healthcare, commercial, manufacturing, and data centers.

On the basis of mobility, stationary segment holds the largest share, in terms of revenue, and is expected to maintain its dominance during the forecast period. This growth is attributed to the increase in demand from industrial sectors such as manufacturing, mining, agriculture, and construction.

On the basis of cooling system, air cooled diesel generator segment holds the largest share, in terms of revenue, and is expected to maintain its dominance during the forecast period. This growth is attributed to the increase in demand from residential and commercial consumers such as apartments, complexes, malls, and others.

On the basis of application, peak shaving segment holds the largest share, in terms of revenue, and is expected to grow at a CAGR of 9.7%. This is owing to the increase in maximum power demand during highly dense populated area and from manufacturing operations (when production rate is high).

On the basis of end use industry, commercial segment holds the largest share, in terms of revenue, and is expected to grow at a CAGR of 9.9%. This is attributed to the increase in demand from the commercial sites such as shops, complexes, malls, theatres, and other applications.

On the basis of the region, the market is analyzed across four major regions such as North America, Europe, Asia-Pacific, and LAMEA. Asia-Pacific garnered the dominant share in 2019, and anticipated to maintain this trend during the forecast period. This is attributed to numerous factors such as presence of huge consumer base and the existence of key players in the region. Moreover, presence of the developing countries such as China, Japan, Australia, and India is anticipated to contribute toward the growth of the diesel generator market in Asia-Pacific.
