Diesel Power Engine Market Analysis

The Diesel Power Engine Market size is estimated at USD 11.55 billion in 2024, and is expected to reach USD 15.74 billion by 2029, growing at a CAGR of 6.39% during the forecast period (2024-2029).

  • Over the medium period, factors such as the increasing demand from the industrial sector and rising power outages have increased the demand for diesel generators, thereby driving the diesel power engine market.
  • On the other hand, the abundance of natural gas, coupled with its environmental soundness, has led to an increasing shift toward natural gas engines as an alternative to diesel engines in various end-user industries and is expected to restrain the growth of the diesel engine market during the forecast period.
  • Nevertheless, the increasing popularity of hybrid power diesel generators presents immense opportunities for the diesel power engine market players in the coming years.
  • Asia-Pacific is expected to be the largest and fastest-growing market, with the majority of the demand coming from countries like India and China.

Diesel Power Engine Market Trends

The Industrial Segment to Dominate the Market

  • • Diesel power generation is the most appropriate standby source for the industrial sector. Generally, the industrial sector consumes more power for its business operations. A diesel power engine offers better reliability and enhances the quality of the power supply.
  • • The demand for electricity is growing worldwide. Rapid industrial expansions and commercial infrastructure development are increasing the utilization of diesel power engines. Significant industries that rely heavily on the power generated from diesel engines are the construction sector, manufacturing, health care, oil and gas, telecommunication and data centers, etc.
  • Diesel generators are equipped with advanced technologies for monitoring electric current, which help automatically start when there are power distortions and failures and revert to switch-off mode when the power comes back.
  • The diesel engine's low volatility rate makes it the finest option in mining fields. Especially in mining fields, heavy-duty activities need a perfect power source and backup. Hence, mining industries rely on diesel-powered engines for better durability. The healthcare segment uses sensitive equipment such as oxygen ventilators, infusion pumps, ECG machines, and defibrillators to treat patients. There is a need for a quality power supply to avoid interruptions. Diesel power engines are hospitals' most reliable backup power sources for uninterrupted power.
  • In the construction sector, projects often stall due to power failures. Constant power interruptions result in delayed project execution, which leads to financial loss. There is a need for a diesel power engine to ensure safety and better power supply on construction sites.
  • Disruptions of power in the manufacturing industry lead to low-volume production and result in the offering of low-standard products. When a blackout occurs in manufacturing divisions, it generally affects all the processes. Hence, the production units rely on the diesel power engine to avoid such failures, which acts as the best power source.
  • The iron and steel industry also uses diesel power engines as backup power in case of power requirements or power shutdown. According to the World Steel Association, as of December 2022, China was the world leader in crude steel production, with 77.9 million metric tonnes produced, a 10% decrease from the previous year. India, Japan, the United States, and Russia trailed far behind.
  • Therefore, based on the abovementioned factors, the industrial segment is expected to dominate the diesel power engine market during the forecast period.

Asia-Pacific to Dominate the Market

  • The increasing infrastructural developments and electricity demand in Asia-Pacific, with the huge increase in average energy consumption rate and GDP growth rate, are expected to promulgate the diesel power engine market.
  • China is the leading diesel generator market in Asia-Pacific owing to increasing infrastructure projects, widening power demand-supply gap, expanding manufacturing facilities across the nation, and rising commercial office spaces.
  • The construction industry in China, one of the largest in the world, has experienced significant growth over the last few decades. Rapid industrialization in China has led to a surge in construction activities, including residential, commercial, and infrastructure construction. The Chinese economy is beginning to recover from the effects of the COVID-19 pandemic as new projects are pushed forward.
  • In April 2023, the Chinese government announced that it was set to increase its spending on large construction and infrastructure projects by USD 1.8 trillion Y-o-Y to help regional economies recover from the pandemic. The growing construction activities require machinery fitted with diesel engines; this is expected to promote the growth of the market.
  • The Indian government has been focusing on developing infrastructure and construction services through focused policies such as open FDI norms, smart city missions, and large budget allocation to the infrastructure sector. In January 2023, the government and the Construction Industry Development Council (CIDC) approved the development of 21 greenfield airports in the country. The growth in the construction sector will, in turn, need diesel generators to power backup, which will create avenues for the development of the market.
  • Under the Smart City Mission, as of November 2022, more than 12.0 million houses were sanctioned under the PMAY-U Mission, out of which more than 6.4 million were completed. The rest are in various stages of construction/grounding. As of 2024, 1174 projects worth USD 855.12 million of Water Body Rejuvenation, Water Supply, Sewage & Sewage Management, and Parks & Green Space Development are ongoing under the AMRUT 2.0 mission. Many of the residential societies in India are equipped with diesel generator (DG) sets to supply electricity during power outages. Thus, such commitments are expected to increase the demand for diesel engines during the forecast period.
  • Moreover, the growing energy demands of the burgeoning manufacturing industry are expected to provide a huge impetus to the generator business in Asia-Pacific. As a result, Asia-Pacific is expected to witness the fastest growth in the global diesel power engine market during the forecast period.
