Diesel Generator Market Overview

A diesel generator is a machine that transforms chemical energy into electrical energy using a diesel engine and an electric generator. It can inject active and reactive powers simultaneously and is considered reliable, durable, cost-effective, hassle-free and fuel-efficient. It is also sturdy and resilient, which allows a diesel generator to withstand rigorous compression. As a result, it finds application as a primary source of energy production in the power plants and as a backup in the industrial, residential and commercial sectors worldwide.

The increasing requirement for an uninterrupted and reliable power supply represents one of the key factors driving the diesel generators market. However, diesel generators are employed in rural and remote places as they are easy to install and can be used independently or in conjunction with other sources like solar power. They can also be utilized for offsetting the peaking power needs on the grid as they can quickly be turned on and off without increasing any lag time. Besides this, the advanced diesel generator can automatically transfer the power supply source from the grid to the generator and vice versa during a power cut.

The global diesel generator market growth is also attributable to a significant rise in the generator adoption rate in the telecommunication and data center sectors. Diesel generators are low cost machines that deliver high power – two traits that make them highly desirable for telecommunication and data centers that survive on round the clock uninterrupted power supply.  

The diesel generator market analysis done in this report focuses on the current and future expected trends of the diesel generator industry and takes a detailed look at the market dynamics, competitive landscape and various market segments contributing towards the improving market outlook globally.

Industrial News:

The Year 2020

  • As of 2020, the steel production in China accounted for approximately 50% of the global steel production, which makes it a huge market for diesel generators as the steel industry is extremely energy-intensive, and its operations are highly dependent on the power generated from the diesel generators during the power outages.

August 2021

  • In August 2021, Cummins India Ltd unveiled its ‘Made in India’ QSK60 G23: 2500-2750 kVA diesel generator. The diesel generator set, an integrated power solution, was launched to meet the increasing power requirements by the industry segments like data centres and large-scale infrastructure projects like railways, airports and other commercial infrastructure project spaces in India.

Diesel Generator Market Dynamics

Industrial Sector Will Drive The Global Diesel Generator Market

The industrial sector, including the mining, manufacturing, agriculture and construction sectors, commands the largest share in the energy consumption matrix. This is because these sectors require constant and uninterrupted power. Also driving the market will be the demand for power supply coming from healthcare facilities and the pharmaceutical industry.

Telecommunication sector base stations also require continuous electrical power to work and provide service and the rate at which the telecom industry has been registering growth will directly impact the diesel generator industry further.

Another major driving factor in the market is the increase in power consumption in developing countries during the forecast period 2019-2025. This increase is expected to overload existing power infrastructure and lead to more and more power outages during the forecast period – an important factor conducive to market growth in the region.

Data Centres Offer New Opportunities For Diesel Generator Market

The economies today are functioning on an increasingly data-heavy model. The management, interpretation and warehousing of all this data require continuous power supply and hence a swift increase in data is creating an upward trend in the global market also. Data center operators tend to spend millions on backup power-generation to ensure convenient and hassle-free service to clients. This creates a critical need for power backup and provides huge potential for diesel generators.

High pace industrialisation and commercialisation of the emerging economies, power demand of the residential sector of developed economies, and an ever-increasing need for power in defense operations will create substantial opportunities for the market growth by 2025.

Major players in the global diesel generator market are investing in product innovations in order to manufacture next generation smart generators with a remote monitoring facility. The additional features of the next-generation generators are expected to bring performance efficiency, thereby inducing growth in the market.

Renewable Energy Market Restraints Growth

The increasing attention of global economies towards renewable energy sources and an ever increasing global demand for clean and green energy will be seen restraining the global diesel generator market growth during the forecast period and beyond.

As more and more people are becoming increasingly aware of their carbon footprint, the demand for carbon-based fuels is expected to decrease in the coming years. This along with the rapidly expanding natural gas generator technology and the maintenance-related challenges for diesel generators will be the main restraining factors for the diesel generator industry.


Very strict governmental guidelines imposed on the use of diesel fuel to ensure reduced emissions and maintaining environmental regulations will make the crux of the challenge that the global diesel generator market growth will face during the forecast period and even beyond. Significantly reducing emission levels, while maintaining performance standards, will prove to be the main challenge for generator manufacturers globally.

Advancement in green technologies has also led to significant demand for natural gas generators that have resilient engine parts such as hardened valves to increase efficiency and performance. Also, natural gas generators are less expensive than diesel generators below 150kW and are highly cost-effective
