Onshore Wind Market

The accelerating expansion of global renewable energy targets is a key driver for the onshore wind market, as governments, utilities, and private investors seek scalable and cost-effective technologies to decarbonize electricity generation. Alongside solar photovoltaics (PV), onshore wind forms the backbone of renewable capacity additions due to its technological maturity and competitive levelized cost of electricity. According to the International Renewable Energy Agency (IRENA), the world added a record 585 GW of renewable power capacity in 2024, with solar PV contributing approximately 452 GW and wind energy around 113 GW, underscoring the dominant role of these two technologies in the global energy transition. As renewable energy targets become more ambitious and electricity demand continues to rise, developers are increasingly investing in integrated wind–solar portfolios to improve grid reliability and optimize land and transmission assets. The complementary generation profiles of onshore wind and solar PV, combined with advances in energy storage and digital grid management, are expected to accelerate project deployment and create sustained growth opportunities across the global onshore wind value chain.

Grid integration challenges remain a significant restraint on the global onshore wind market, limiting the pace at which new capacity can be deployed despite strong policy support and declining generation costs. Many of the world’s best wind resources are located in remote regions where transmission infrastructure is insufficient to transport electricity efficiently to major demand centers. As a result, developers frequently encounter delays in securing grid connections, curtailment risks, and rising project costs. In Germany, congestion between northern wind-producing regions and southern industrial hubs has necessitated costly redispatch measures and highlighted the need for expanded transmission corridors. In the United States, renewable energy projects face lengthy interconnection queues, with grid upgrade requirements delaying commercial operations in several states. India continues to invest in the Green Energy Corridor program, yet transmission bottlenecks in wind-rich states such as Tamil Nadu and Gujarat can hinder the timely integration of projects. Similarly, western and northern China have historically experienced curtailment due to mismatches between renewable generation and transmission capacity, although ongoing ultra-high-voltage network investments are helping address these issues. Without accelerated grid modernization, storage deployment, and cross-regional transmission expansion, integration constraints are expected to remain a key obstacle to sustained growth in the onshore wind market.

Repowering aging onshore wind farms presents a significant growth opportunity for the global onshore wind market by enabling operators to replace older, lower-capacity turbines with modern, high-efficiency models while utilizing existing project sites and grid connections. Many wind farms commissioned in the late 1990s and early 2000s are approaching the end of their design life, making them ideal candidates for upgrades that can substantially increase electricity generation without requiring extensive new land acquisition. Repowering also reduces maintenance costs, improves reliability, and enhances project economics through higher capacity factors and advanced digital control systems. For instance, Germany, one of the world’s earliest adopters of wind energy, has numerous aging installations eligible for repowering under supportive regulatory frameworks. For instance, in June 2026, Vestas secured a 29 MW repowering order in Japan from M Winds Hachiryu Co., Ltd., a group company of Meidensha Corporation, for the Hachiryu Wind Power Station Repowering Project. The contract includes the supply and installation of seven V136-4.2 MW wind turbines along with a 10-year service agreement. Turbine delivery is scheduled for the first quarter of 2028, with project commissioning expected later in 2028, underscoring the continued investment in repowering aging wind assets to improve efficiency and extend operational life. Similarly, Denmark, Spain, and parts of the United States are seeing increased investment to replace legacy turbines with larger units capable of producing significantly more energy. This trend creates new revenue streams for turbine manufacturers, component suppliers, engineering firms, and operations and maintenance service providers while supporting national renewable energy and decarbonization goals.

Insufficient transmission infrastructure remains a major challenge for the global onshore wind market, limiting the efficient integration of new renewable energy capacity into national power grids. Many of the most productive wind resources are located in remote regions, requiring extensive investments in high-voltage transmission lines, substations, and grid reinforcement before electricity can be delivered to demand centers. Delays in transmission planning and permitting often result in project postponements, curtailment of generated power, and reduced investment returns for developers. In rapidly expanding markets, existing grid networks frequently struggle to accommodate the growing share of variable renewable energy, creating congestion and interconnection bottlenecks. Moreover, the pace of transmission expansion often lags behind wind farm development, particularly in emerging economies with limited infrastructure funding. Lengthy regulatory approvals, land acquisition issues, and rising construction costs further compound the challenge. Addressing these infrastructure gaps through coordinated grid modernization, digital management systems, and cross-regional transmission investments will be critical to unlocking the full growth potential of the global onshore wind market.
