Key Market Segments

By Fuel Type

• In 2024, coal reigned supreme in the steam turbine MRO (Maintenance, Repair, and Overhaul) market, commanding over 53.3% of the total share. This dominance reflects coal’s enduring role as a cornerstone of global electricity generation, prized for its affordability and widespread availability despite the accelerating pivot to cleaner energy alternatives.
• Coal-fired power plants, many of which have outlived their projected lifespans, continue to drive robust demand for MRO services as operators prioritize maintenance and repairs to sustain turbine efficiency and performance. Looking ahead to 2025, coal is expected to retain its top position, though its dominance may soften slightly as other fuel types gradually gain momentum.

By Service Type

• In 2024, maintenance services led the steam turbine MRO market, securing more than 52.3% of the share. This prominence underscores the critical need for routine upkeep—think inspections, part swaps, lubrication, and monitoring—to keep turbines humming smoothly and ward off costly breakdowns.
• For power plant operators, where every minute of downtime stings, these activities are non-negotiable. The appetite for maintenance services is set to climb steadily through 2025, maintaining its market lead even as repair and overhaul services see growing demand. As both new and aging turbines require ongoing attention to maximize efficiency and longevity, maintenance will remain the market’s bedrock.

By Service Provider

• In 2024, Independent Service Providers (ISPs) took the lead in the steam turbine MRO market, grabbing over 44.2% of the share. Their edge comes from a blend of niche expertise, agility, and customer-focused solutions, often outpacing larger competitors with lower costs, quicker turnarounds, and tailored offerings.
• While Original Equipment Manufacturers (OEMs) and other players are ramping up competition, ISPs are poised to hold their ground in 2025, buoyed by plant operators’ preference for cost-effective, efficient service options. Their market share might waver slightly, but demand for their adaptable approach remains a powerful draw.

By Capacity

• In 2024, turbines rated 600 MW and above dominated the steam turbine MRO market, accounting for over 42.4% of the share. These heavyweights, common in high-output power plants, are vital to meeting hefty electricity demands in utility and industrial settings.
• Their complexity and pivotal role fuel a steady need for specialized MRO services. While smaller-capacity turbines are carving out a bigger niche, the 600 MW and above segment should hold firm through 2025, driven by the intricate maintenance needs of these units and their prevalence in older plants still chugging along.

By End-Use Industry

• In 2024, power generation providers towered over the steam turbine MRO market, claiming more than 58.4% of the share. This sector’s dominance reflects steam turbines’ indispensable role in churning out electricity for homes and industries alike, fueled by a relentless global hunger for dependable power.
• Even as wind and solar nibble at the edges, steam turbines in coal, gas, and nuclear plants will keep MRO services in high demand through 2025, with frequent upkeep essential to minimize downtime and stretch operational lifespans. The 24/7 nature of many power plants only amplifies the need for consistent maintenance, cementing this industry’s lead.

Regional Analysis

• North America solidified its leading role in the steam turbine MRO (Maintenance, Repair, and Overhaul) market, capturing 46.8% of the global share, equivalent to roughly USD 11.7 billion.
