Wind Turbine Gearbox Repair and Refurbishment Market Size - By Type (Repair, Refurbishment), By Deployment (Onshore, Offshore), Growth Forecast, 2025 - 2034

Wind Turbine Gearbox Repair and Refurbishment Market Size

The global wind turbine gearbox repair and refurbishment market size was estimated at USD 1.6 billion in 2024. The market is expected to grow from USD 1.7 billion in 2025 to USD 2.5 billion in 2034, at a CAGR of 4.3%, according to Global Market Insights Inc.

• High cost of gearbox replacement, accounting for a significant portion of overall turbine capital expenditure, is set to propel repair and refurbishment services adoption. Gearboxes are subjected to heavy loads, fluctuating wind speeds and long operational hours, leading to mechanical stress and eventual wear. Thus, complete replacement required substantial investment and downtime, making refurbishment a more cost-effective solution that extends the lifespan of existing assets.
   
• Wind turbine gearbox repair and refurbishment refer to the process of restoring a wind turbine’s gearbox to optimal working condition through targeted maintenance, component replacement, and performance upgrades. This involves diagnosing faults, repairing damaged parts, and reassembling the gearbox to meet operational standards. Refurbishment may also include enhancements to improve efficiency, reliability, and lifespan beyond the original specifications.
   
• Growing companies' investments in developing new refurbishment and repair centers for gearboxes to help the wind turbine sector manage operations and maintenance expenses more efficiently will drive the process growth. For instance, in August 2025, ERIKS established a Yaw Gearbox Cell at its Aberdeen Centre of Excellence for Renewables, providing quick refurbishment solutions for yaw gearboxes in onshore wind turbines. This initiative significantly reduces downtime from months to hours and is part of a USD 583,056 investment, contributing to a total of over USD 874,584 invested in the facility within the last year.
   
• The wind turbine gearbox repair and refurbishment market was valued at USD 1.5 billion in 2021 and grew at a CAGR of 2.2% through 2024. The growing installed base of aging wind turbines, particularly in mature markets such as Europe, North America, and parts of Asia, results in turbines surpassing their original design times, leading to increased frequency of gearbox failure and performance degradation. This escalates the popularity of refurbishment, allowing operators to restore efficiency while avoiding full system overhauls.
   
• Asia Pacific is among the dominant regions, primarily driven by the rapid expansion of wind capacity in China, India and Southeast Asia, where a large fleet of turbines is approaching mid-life, increasing the need for maintenance. For instance, China's National Energy Administration (NEA) reports that the country's wind power capacity surged by 18%, adding 80 GW to reach a total of nearly 521 GW.
   
• In contrast, India made notable strides, adding 4.15 GW of new capacity, up from 3.25 GW in the fiscal year 2023–24. These statistics are expected to improve further in the forecasted period, leading to an escalation in the demand for repair and refurbishment services to reduce O&M costs and continue operations.
   
• Furthermore, in China, growing independent service providers coupled with advanced condition monitoring technologies are enhancing service quality and reliability. Supportive renewable energy policies and the region’s focus on lowering the levelized cost of electricity will accelerate the adoption of gearbox refurbishment as a sustainable lifecycle management strategy.
   
• Middle East & Africa is the fastest-growing region in the market, driven by growing wind projects in South Africa, Morocco, Egypt and emerging Gulf markets. Harsh climatic conditions of MEA create demand for regular repair services, leading to uplift the business scenario. Additionally, regional governments’ push for renewable energy, alongside growing local service partnerships, is reinforcing the adoption of gearbox repair and refurbishment across MEA’s expanding wind sector.
   

Wind Turbine Gearbox Repair and Refurbishment Market Trends

• Growing technological advancements strengthen the business scenario for gearbox repair and refurbishment. The ongoing integration of predictive maintenance systems and artificial intelligence analytics enables the early detection of wear and anomalies, further improving the industry outlook. These advancements enable operators to perform targeted repairs before catastrophic failure occurs, enhancing reliability and reducing unplanned outages, leading to uplift in service growth.
   
• Rising deployment of wind turbines in developing regions, including Latin America and the Middle East & Africa, has created lucrative opportunities for wind turbine gearbox repair and refurbishment companies to uplift their presence in these economies. For instance, in July 2022, Wärtsilä secured its first long-term contract for wind turbine gearbox repair services in Brazil. The agreement includes repairing four gearbox models, each with an average power of 2MW, covering disassembly, inspection, sourcing original parts, assembly, and testing.
   
• Rising prevalence of long-term service agreements and third-party service providers has broadened access to cost-effective repair solutions. A growing number of independent service providers and specialized engineering firms are entering the market, offering competitive pricing, localized expertise and flexible contracts compared to OEM-led services. This competition is enhancing accessibility and reducing costs for refurbishment solutions, thereby expanding adoption among small and medium-sized operators who struggle with high O&M expenditures.
   
• Global expansion of offshore wind farms, where logistical challenges make complete gearbox replacement extremely costly and time-intensive. As per Statista, as of early 2025, the global installed offshore wind capacity exceeded 68 GW, with over 319 operating projects and more than 13,000 turbines. These growing statistics make repair and refurbishment solutions an attractive choice, which reduces service vessel trips, limits crane requirements and ensures faster restoration of turbine functionality. This cost-effective alternative is expected to grow significantly as offshore continues to rise, particularly in regions such as Europe, China, and the U.S.
   
• Additionally, the establishment of regional hubs and localized manufacturing of spare parts is reducing logistical bottlenecks and delivery times. This localization not only ensures a quicker turnaround for gearbox repairs but also lowers transportation costs, making refurbishment more attractive than importing a new gearbox from centralized facilities, which in turn drives service penetration. Moreover, increasing investor pressure on wind project returns is prompting asset managers to optimize efficiency solutions that directly support these financial objectives, making them a central part of lifecycle management strategies.
