Diesel Generator Market Size, Share & Trends Analysis Report By Power Rating (Low Power, Medium Power, High Power), By Application (Residential, Commercial, Industrial), By Region, And Segment Forecasts, 2023 - 2030

Report Overview

The global diesel generator market size was valued at USD 15.16 billion in 2022 and is expected to expand at a compound annual growth rate (CAGR) of 9.4% from 2023 to 2030. Increasing demand for energy globally far outstrips the supply. Factors such as continuous population growth, infrastructure development, and rapid industrialization in emerging economies are pacing the power demand. Diesel generators have numerous advantages such as low operating costs and better fuel efficiency. Thus, they are much more popular in developing regions, especially in the Asia Pacific region. Along with its advantages, it had many other drawbacks which include noise pollution, and emissions of hazardous gases. The World Nuclear Association has projected that the electricity requirement is expected to double the current consumption. According to the U.S. Department of Energy, solar energy will be the most abundant energy source available.

Significant growth in the economies of major developing nations such as India, Brazil, and others is expected by 2050. India is expected to grow from being the third largest to the second largest economy in the world, only after China in terms of GDP at PPP (purchase power parity).Countries such as Brazil, India, and South Africa are already suffering due to low power supply. Emerging economies are expected to account for 65% of the global economy.

The market in the U.S. is anticipated to witness substantial growth owing to rising costs of power outages across several IT-enabled service firms and data centers along with growing consumer awareness toward the requirement for reliable emergency power supply. In addition, the market is also driven by the rising vulnerability of grid power stations to disasters caused by changing weather conditions across the region.

Solution providers across the diesel generator market are primarily responsible for generator system manufacturing, installation, maintenance, and repair. Generator dealers or electrical contractors establish product supply and maintenance contracts with end-market consumers present across commercial places, residential places, and small-size companies using generators as emergency power backup systems. Moreover, companies also assign an in-house monitoring engineer to supervise a large number of generators in industrial-scale operations.

Stringent government regulations regarding the reduction of harmful carbon emissions are expected to boost the penetration of gas-based generators over diesel generators. This trend is anticipated to restrict the market demand for diesel generators across all the end-use sectors. However, low operating costs and low initial investment are among the key factors sustaining the current requirement for diesel generator sets.

Power Rating Insights

The low power generator segment accounted for a significant revenue share of 44.0% in 2022 owing to the presence of a wide application base in commercial and residential sectors. Generators with a capacity below 80 kW are used as power backup solutions in residential homes to power devices such as water pumps, water purifiers, AC units, geysers, and others. Furthermore, the low cost of these generators is expected to play a crucial role in boosting product demand over the forecast years.

The high power generator segment is expected to attain a significant CAGR over the forecast period owing to its rising demand in power, manufacturing, and the marine industry, where there is a huge requirement for continuous power supply. High-power diesel generators are installed for power generation and distribution across off-grid remote areas, as it is not economically feasible to supply direct grid power to several remote places.

Application Insights

The commercial application segment occupied the largest market share of 45.34% in 2022 and is projected to register a substantial growth rate over the forecast period. The high growth rate can be attributed to the wide application scope including several industries such as data centers, government centers, educational institutions, healthcare, hospitality, telecom, agriculture, and others. Diesel gensets are used across commercial establishments to back up sudden power interruptions such as voltage fluctuations and electrical outages, if not tackled, add up to financial losses.

The industrial diesel generator segment accounted for the second-largest revenue share in 2022. The segment includes the manufacturing and construction sector, electric utilities, mining, transport & logistics, and oil & gas sector, these sectors draw huge product demand citing their heavy power consumption operations. Favorable government policies for industrial development in developing economies such as China, India, and Brazil are among the key factors driving the segment’s growth.

The residential segment is expected to witness significant growth over the forecast period on account of rising customer awareness, growing load demand on the primary grid, and the growing number of power failures. Moreover, diesel generators serve as a reliable secondary power source in households in case of a grid failure or electrical outages.

Regional Insights

Asia Pacific was the largest regional segment with a share of 28.88% in 2022, with China being the major revenue contributor with USD about 2,997.0 million. The rising number of manufacturing facilities and infrastructure projects, rising electricity demand-supply gap, and rapid development of commercial office spaces in China are anticipated to provide a boost to the industry landscape across the region.

In Asia Pacific, diesel generator sets are predominantly used for backup as the region has a moderately developed power infrastructure that supplies low-cost electricity from the utility grid. The demand pattern for diesel generator sets depends on different factors such as the country’s power infrastructure, emission norms, and purchasing power of customers.

North America accounted for a significant market share in 2022, with the U.S. occupying a dominant revenue contributor position across the region. Continuously developing infrastructure of data centers and other commercial markets along with the growing vulnerability of power grids to weather-based outages has led to strengthening demand for reliable backup power solutions, in turn stimulating the demand for diesel generators across the region.

Major industry participants are practicing several organic and inorganic strategic growth initiatives to expand their service portfolio and enhance their foothold across the diesel generator industry. Some prominent players in the global diesel generator market include:

• AKSA power generation company

• Atlas Copco AB
