Overview
New York, NY – August 19, 2025 – The Global Generator Sets Market is projected to reach USD 78.1 billion by 2034, up from USD 35.2 billion in 2024, with a CAGR of 8.3% during the 2025–2034 forecast period. In 2024, the Asia-Pacific (APAC) region led the market, holding a 44.8% share, equivalent to USD 15.76 billion in revenue.
Generator sets, encompassing diesel, gas, or hybrid engines, provide backup, prime, and emergency power. Industrial generator sets, typically rated above 10 kW, are critical for infrastructure in sectors like manufacturing, healthcare, telecommunications, and data centers. The market is driven by increasing grid disruptions and power outages, necessitating reliable off-grid and backup power solutions across residential, commercial, and industrial sectors.
In India, industrial captive generation accounts for approximately 75,000 MW of diesel capacity (excluding sets below 100 kVA) as of FY 2023–24, primarily for emergency and industrial backup power. India’s National Electricity Plan targets a shift from new fossil-fuel power plants, aiming for non-fossil fuel sources to contribute ~44.7% of electricity generation. This policy encourages distributed backup generation through cleaner gas or hybrid gensets.
The Deen Dayal Upadhyaya Gram Jyoti Yojana (DDUGJY) achieved nearly 100% village electrification, boosting demand for backup systems in rural areas prone to grid instability, particularly during monsoons or in remote regions. The ‘ADEETIE’ scheme, launched by the Union Ministry of Power with ₹1,000 crore in funding, supports MSMEs in adopting energy-efficient technologies, including advanced genset systems. It allocates ₹875 crore for interest subvention and ₹50 crore for capacity-building, expecting to mobilize over ₹9,000 crore in investments.
This initiative is likely to drive demand for fuel-efficient gensets in industrial clusters across states like Andhra Pradesh, Telangana, Kerala, Karnataka, and Tamil Nadu. The National Action Plan on Climate Change, including the National Solar Mission, promotes reduced carbon intensity and renewable energy adoption, indirectly fostering the use of hybrid and low-emission gensets. The Make in India initiative supports local genset manufacturing, though the manufacturing sector’s share in GDP remains below 16%.

Key Market Segments
By Power Rating Analysis
In 2024, the >50 kVA – 125 kVA segment dominated the generator sets market, holding a 31.2% share. This power range is favored by medium-sized industries, construction sites, commercial buildings, and small manufacturing units requiring a stable, moderate power supply. These gensets strike a balance between performance and cost, making them ideal for users needing reliable backup power without the higher costs of larger units. Their widespread use in regions with frequent power disruptions, particularly in developing countries, reinforces this segment’s strong market position.
By Fuel Analysis
Diesel generators led the market in 2024, capturing a 73.4% share. Their dominance stems from diesel’s reliability, efficiency, and suitability for heavy-duty applications. Widely used in construction, factories, hospitals, and telecom towers, diesel gensets deliver stable power for extended periods. The widespread availability of diesel fuel and lower maintenance requirements compared to other fuel types make it a practical choice for both urban and remote settings.
By Application Analysis
In 2024, standby generators held a 51.8% market share, primarily serving as backup power solutions. These systems are extensively deployed in hospitals, data centers, commercial buildings, and residential complexes to ensure continuity during power outages. Their automatic activation during grid failures enhances their reliability and convenience. Growing concerns over grid instability and frequent weather-related blackouts have sustained strong demand for standby generators.
By End Use Analysis
The commercial sector dominated the market in 2024, accounting for a 54.7% share. This reflects the critical need for uninterrupted power in hotels, shopping malls, office buildings, telecom towers, and healthcare facilities. Consistent power is essential for maintaining operations, preventing service disruptions, and ensuring customer satisfaction. The surge in urban development and commercial real estate projects has further driven demand for generator sets in this sector.
Regional Analysis
In 2024, the Asia-Pacific (APAC) region maintained its leadership in the generator sets market, contributing 44.8% of global revenue, equivalent to USD 15.76 billion.
