Diesel Generator Market Size & Trends

The global diesel generator market size was estimated at USD 16.36 billion in 2023 and is expected to grow at a CAGR of 9.6% from 2024 to 2030. Increasing energy demand globally far outstrips the supply. Factors, such as continuous population growth, infrastructure development, and rapid industrialization in emerging economies drive power demand. Diesel generators are favored for their numerous benefits, including low operating costs and superior fuel efficiency, making them particularly popular in developing areas, notably the Asia Pacific region. Despite these advantages, they also have several disadvantages, such as noise pollution and the emission of harmful gases. The World Nuclear Association has predicted that the electricity demand is likely to double from current levels. In addition, the U.S. Department of Energy forecasts that solar energy will become the most plentiful energy source available.

Diesel Generator Market Size by Power Rating, 2020 - 2030 (USD Billion)

Significant growth in the economies of major developing nations, such as India and Brazil, 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 a low power supply. Emerging economies are expected to account for 65% of the global economy. The U.S. market is anticipated to witness substantial growth owing to rising costs of power outages across several IT-enabled service firms and data centers and growing consumer awareness of the need for a 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 are mainly responsible for manufacturing, installing, maintaining, and repairing generator systems. Dealers or electrical contractors typically enter into supply and maintenance agreements with end-market consumers, which include commercial establishments, residential areas, and small businesses that use generators for emergency power backup. In addition, companies often appoint an in-house monitoring engineer to oversee the operation of numerous generators in industrial-scale settings. Stringent government regulations regarding reducing harmful carbon emissions are expected to boost the penetration of gas-based generators over diesel generators. This trend is anticipated to restrict the demand for diesel generators across all end-use sectors. However, low operating costs and low initial investment are among the key factors sustaining the current requirement for diesel generator sets.

Market Concentration & Characteristics

The diesel generator market is slightly consolidated in nature with the presence of key industry players, such as AKSA Power Generation Company, Atlas Copco AB, Caterpillar, Cummins Inc., Doosan Portable Power, Generac Power System Inc., Honda India Power Products Ltd., and Kohler Co., which hold significant market shares. These companies often use aggressive marketing strategies, R&D initiatives, and M&As, to strengthen their market position and expand their product offerings.

Various product substitutes are available for diesel generators, including natural gas generators, solar power systems with battery storage, and grid power solutions in areas with reliable electricity infrastructure. Natural gas generators offer cleaner emissions than diesel and are preferred in regions with accessible natural gas supplies. Solar power systems are gaining popularity due to the falling costs of solar panels and battery storage, providing renewable energy solutions with lower operating costs over time. Diesel generators face competition as backup power solutions for locations with stable grid power. These substitutes are increasingly attractive due to environmental concerns, cost efficiencies, and advancements in renewable energy technologies, increasing competition for diesel-powered generators.

Diesel Generator Industry Dynamics

Regulations significantly impact the market by influencing emissions standards, operational restrictions, and market entry requirements. Stringent emissions regulations, such as limits on nitrogen oxides (NOx) and particulate matter, compel manufacturers to invest in cleaner technologies or face penalties, affecting production costs and product pricing. Operational restrictions, such as noise limits and zoning regulations, dictate where and how diesel generators can be used, impacting their market reach and application flexibility. Government incentives and subsidies for cleaner alternatives like renewable energy sources further shape market demand, influencing consumer preferences and investment decisions. Overall, regulatory dynamics are crucial in shaping the competitive landscape and driving innovation within the market.

Power Rating Insights

The power generator segment accounted for a significant market revenue share of 44.0% in 2023, owing to a broad application base in the 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 growth rate over the forecast period owing to its rising demand in power, manufacturing, and 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 revenue share in 2023 and is projected to grow substantially over the forecast period. The high growth rate can be attributed to the broad application scope, including several industries, such as data centers, government centers, educational institutions, healthcare, hospitality, telecom, and agriculture. Diesel generators are used as backups across commercial establishments in case of sudden power interruptions, such as electrical outages and voltage fluctuations, which add to financial losses if not tackled.

Diesel Generator Market Share by Application, 2023 (%)

The industrial diesel generator segment accounted for the second-largest revenue share in 2023. The segment includes the manufacturing & construction, electric utilities, mining, transport & logistics, and oil & gas sectors. These sectors draw huge product demand due to 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 growth. The residential segment is expected to witness significant growth over the forecast period owing to rising customer awareness, growing load demand on the primary grid, and increasing number of power failures. Moreover, diesel generators are a reliable secondary power source in households in case of grid failure or electrical outages.

Regional Insights

The diesel generator market in North America accounted for a share of 20.2% in 2023. The presence of prominent diesel generator OEMs and the growing demand for backup power are the primary factors driving the regional market growth.
