디젤 발전기 시장 규모, 점유율 및 동향 분석 보고서 : 정격 출력별, 용도별, 지역별, 부문별 예측(2026-2033년)

Diesel Generator Market Summary

The global diesel generator market size was estimated at USD 19.33 billion in 2025 and is projected to reach USD 40.99 billion by 2033, growing at a CAGR of 9.9% from 2026 to 2033. A diesel generator operates by combusting diesel fuel within an internal combustion engine to produce mechanical energy, which subsequently drives an alternator to generate electricity.

Continued technological progress in power generation systems and increasing adoption of distributed energy solutions are major factors fostering market expansion.

The rising demand for reliable backup power, particularly in regions with unstable grid networks, along with growing requirements across the industrial, commercial, and residential sectors, is also strengthening demand in the emergency power diesel generator industry.

Diesel generators remain extensively used for standby, prime, and continuous power applications, where medium- and high-capacity units are preferred due to their durability, operational flexibility, and cost-effectiveness. Their ability to deliver instant power during outages and support critical operations in sectors such as healthcare, manufacturing, data centers, and construction further reinforces market growth. The ongoing expansion of infrastructure projects in countries such as the U.S., Japan, India, and China, along with supportive government investments in industrial development and power reliability improvements, continues to drive the adoption of diesel generators globally.
