Gas Turbine MRO Market in the Power Sector Size, Share & Trends Analysis Report By Service Type (Maintenance, Repair, Overhaul), By Provider Type (OEMs, Independent Service Providers, In-house) and By Region (North America, Europe, APAC, Middle East and Africa, LATAM) Forecasts, 2026-2034

Gas Turbine MRO Market in the Power Sector Size & Growth Analysis

The global gas turbine mro market in the power sector size was valued at USD 15.56 billion in 2025 and is projected to grow from USD 16.10 billion in 2026 to USD 21.13 billion by 2034, registering a CAGR of 3.46% during the forecast period from 2026 to 2034. Asia Pacific dominated the gas turbine mro market in the power sector with a market share of 36.8% in 2025

Service Type Insight

The maintenance segment dominates the global market over the forecast period.Companies and power plant operators must perform regular maintenance services, including periodic inspections, parts replacement, diagnosis, and renovations, to ensure that power equipment works in good condition. This improves operational performance and ensures the long-term and stable operation of the facility. The maintenance cycle starts with the pre-outage planning, continues through the outage, and ends with the post-outage assessment.

In addition, a large number of power utilities and independent power producers enter into long-term service agreements (LTSA) to meet their plant needs across a range of services, which include all aspects of support, such as fleet management, inventory management, maintenance, repair, and overhaul, and the provision of day-to-day technical support of gas-turbines. Such agreements help reduce the overall costs, thereby enhancing the capacity of gas turbines through higher-performance parts. This is expected to increase the demand for maintenance services.

A major overhaul service for each gas turbine will be performed for 48,000 firing hours. A major gas turbine overhaul service includes gas turbine disassembly, rotor removal, clearance measurements, initial positions, blade inspection and replacement, initial position and clearance measurements, an inspection of the main gearbox, inspection and cleaning of oil pumps, cleaning of fan motor set, and inspection and cleaning of the main gearbox and lube oil cooler. Further, according to the Energy Information Administration, the global capacity of natural gas-fired power plants is expected to increase from 1,839 GW in 2020 to around 2,414 GW in 2050. It will directly aid the gas turbine overhaul services market as the number of gas turbines increases due to the demand for clean energy through natural gas and aging power systems, which would require overhaul services.

Provider Type Insight

The independent service providers segment owns the highest market share.Independent service providers (ISPs) are key in keeping a gas turbine in top condition. Unlike the maintenance and operation services an original equipment manufacturer (OEM) provides, an ISP works across various models and brands, providing maintenance, service, and overhaul support for various gas turbines used in the power generation sector. Although OEMs always have a place in maintaining gas turbines, ISPs can help reduce costs and benefit plant operators where gas turbines are installed.

Furthermore, independent service providers offer field services for borescope inspections, planned and unplanned maintenance, unit troubleshooting, and generator support in the gas turbines. Independent service providers ensure that owners and operators of gas turbines receive high-quality, innovative, and cost-effective solutions tailored to their individual operational goals.

In-house gas turbine services refer to the MRO services performed within the power plant instead of relying on OEMs or Independent Service operators. The power plant operator uses its employees and time to perform services, like borescope inspections, planned and unplanned maintenance, unit troubleshooting, and generator support in the gas turbines. Thus offering gas turbine owners and operators more choice and flexibility to organize post-warranty operations and maintenance of gas turbines. The in-house service providers also offer much flexibility over the MRO services of a gas turbine, as the in-house service team ensures its 24/7 availability along with instant maintenance and overhaul services without lost time and workforce.

Regional Analysis

Asia-Pacific emerged as the largest regional market for gas turbine MRO market in the power sector in 2024, holding a 23.01% share, and is expected to expand substantially in the global power sector during the forecast period.The rapid expansion of the Asia-Pacific region is fueling the demand for electricity throughout the region. Consequently, the number of new gas turbine installations has increased exponentially in recent years. From 2018 to 2019, the electricity generation from natural gas increased by approximately 20 TWh. In 2021, Japan was one of the largest natural gas importers; 20% of the nation's electricity was generated by natural gas. Japan also operates numerous gas-fired power plants, routinely maintained to reduce the likelihood of blackouts.

• For instance, in March 2022, the Japanese government announced that three gas-fired power facilities with a combined power generation capacity of 1,900 MW would be shut down for two months for routine maintenance. In March, the average temperature in Tokyo rose to 21 degrees Celsius, reducing the demand for electric heating services, so the decrease in power generation capacity will have a limited impact on the country's power consumption pattern. All such factors contribute to regional market growth.

North America Market Trends

North America is one of the largest gas turbine MRO services markets, with the United States, Canada, and Mexico contributing most of the demand. Growing investments in new large gas-fired combined cycle power generation due to the region's rising electricity demand is one of the essential factors driving this market. In addition, North America remains the largest market for funding and commercializing innovative technologies and has already attracted many energy-focused technology companies.

The US market is driven by the outdated fleet of coal-based power plants being replaced with gas-based power plants to cut greenhouse gas emissions. The expansion of the gas turbine MRO services market in the United States is projected to be accelerated by building new natural gas power plants and combined heat and power plants.

Additionally, as per the Energy Information Administration (EIA), approximately 59 GW of the presently operational coal-fired capacity in the United States will be retired by 2035. Increased cessation of coal-based power plants has paved the way for increased investments in gas-based power plants requiring extensive MRO services.

Europe Market Trends

In Europe, the most significant transition in the electricity system over the past few years has been from coal-fired to natural gas-fired generation. Austria, Denmark, France, the United Kingdom, and five other countries in the region have announced or passed legislation to replace coal in their energy mix. However, the Balkans, Turkey, and the majority of Eastern European nations continue to invest in coal-fired power facilities. These developments fuel the demand for gas turbine MRO services in power plants.

Even though renewables are among the least expensive energy sources by 2020, 13 European nations are still planning to construct new coal-fired power facilities. Turkey (37,569 MW), Poland (9,590 MW), and Bosnia-Herzegovina are the countries with the greatest proposed coal capacity additions (4,080 MW). The emphasis of these nations on coal-fired power plants is likely to inhibit market expansion.

The South American region is expected to see significant development following the inauguration of the new gas-powered power plants. This is mainly because Argentina and Venezuela have huge natural gas resources. This is anticipated to create opportunities for maintenance, repair, and overhaul services for gas turbines in the region soon. As of 2020, Argentina has more than ten operational gas-fired power facilities, with additional projects in various stages of installation and construction. For instance, in July 2021, Wartsila Oyj Abp announced that commercial operations had begun at Argentina's Central Térmica Manantiales Behr facility. Wartsila Oyj Abp was also awarded a 10-year long-term service contract to provide maintenance and operational services for the gas-fired power facility.
