The large generator market size is projected to reach US$ 17.9 billion by 2031 from US$ 28.9 billion in 2023. The market is expected to register a CAGR of 6.2% in 2023–2031. Increasing power consumption, technological advancement of large generators, and rapid growth of energy transition are among the key factors driving the large generator market.
The large generator market is expected to experience considerable growth during the analyzed timeframe owing to the rising number of power generation projects as well as the rise in demand for portable power generators, particularly in remote locations. Additionally, the rise in investment toward the replacement or upgradation of power infrastructure across the globe is projected to propel the demand for large generators. Moreover, the rapid industrialization across the developing regions is further projected to boost the large generator market growth in the coming years.
With the mounting population and industrialization, the demand for energy is also rising at the global level. The rise in energy consumption also boosted the need for power generator infrastructure in developing and developed economies. This has resulted in driving the demand for large generators across the globe. In addition, the Large population, high per capita income, and rapid industrialization are driving the construction, manufacturing, and telecom industries in the Asia Pacific. Further, highly industrialized countries in the Asia Pacific, such as China, India, South Korea, and Japan, are reporting increasing overall energy consumption. These countries are increasing their focus on boosting electricity production through various sources such as oil & gas, geothermal, nuclear, and others, which in turn is supporting the large generator market growth in Asia Pacific.
Declining electricity consumption in advanced economies slowed the growth of global electricity demand in 2023. Global electricity demand grew by 2.2% in 2023, as compared to 2.4% growth registered in 2022. While developing countries, including China, India, and other countries in Southeast Asia, experienced significant growth in electricity demand in 2023, advanced economies experienced significant declines due to a weak macroeconomic environment and high inflation, which led to a decline in manufacturing and industrial output. Global electricity demand is expected to increase faster over the next three years, growing by an average of 3.4% per year through 2031. The increases will be driven by an improving economic outlook, which will contribute to faster growth in electricity demand in both developed and emerging markets. Hence, the rise in demand for power generation in the developing region is projected to fuel market growth in the coming years.
Connecting rural communities to national power grids in developing countries is not economically viable. Network infrastructure in developing countries could be improved at best. Diesel generators offer an ideal solution. They can be used individually or as part of a combined power system in conjunction with wind and solar energy. For instance, agriculture generally makes up large parts of developing countries. India's rural irrigation network is estimated to be powered by around 4 million small diesel generators. Diesel generators are low-tech, long-lasting, portable energy sources and provide important energy solutions in developing countries. As developing countries struggle with increasing infrastructure demands, demand for electricity continues to outstrip supply. This leads to peak power deficits, blackouts, and brownouts.
Diesel generators can ensure the security of the power supply in the case of a grid failure. Compared to alternatives such as solar and wind energy, diesel generators represent the most cost-effective solution in terms of initial investment costs for developing countries. Due to the limited budgets of developing countries, diesel generators remain the best solution for primary and emergency power generation. As developing countries continue to industrialize and populations continue to grow, energy demand will increase. Diesel generators represent an important source of energy in developing countries. This trend is expected to continue for the foreseeable future. Hence, the adoption of diesel generators in backup power and peak shaving applications is projected to boost the market growth from 2025 to 2031.
Key segments that contributed to the derivation of the large generator market analysis are fuel, power rating, and application.
The geographic scope of the large generator market report is mainly divided into five regions: North America, Europe, Asia Pacific, Middle East and Africa, and South America.
Asia Pacific dominated the large generator market in 2023. The Asia Pacific region includes Australia, China, Japan, India, South Korea, & the Rest of Asia Pacific. Rapid industrialization and a rise in investment toward the expansion of oil and gas, chemicals, power generation, water treatment, and other industries are expected to drive the growth of the market in this region. In addition, the rise in chemical production across the emerging markets in Asia, including China, India, and others, is anticipated to fuel the demand for large generators, which in turn is expected to drive the market growth from 2025 to 2031.
