At TPI, we deeply partner with leading wind turbine OEMs to build flexible, cost-competitive, and world-class manufacturing hubs. Leveraging our strategic global footprint, we deliver up to 18 GW of wind turbine capacity annually. By integrating the latest wind blade designs and advanced manufacturing technologies, we optimize the total delivered cost for our clients while continuously driving down the Levelized Cost of Energy (LCOE) for wind energy facility owners and operators worldwide. BladeAssure enhances TPI’s blade capabilities by integrating automated controls and real-time process validation on the shop floor, accelerating the scaling of next-generation blade designs while ensuring strict manufacturing precision, structural reliability, and standardized quality.
Why Leading OEMs Partner with TPI
At TPI, our wind blade manufacturing process is built on a culture of innovation and collaborative Design for Manufacturability (DFM). We partner closely with original equipment manufacturers (OEMs) to deliver custom wind blades engineered for optimal aerodynamic performance, long-term reliability, and the lowest total delivered cost.
With our advanced composite expertise, TPI has the capability to manufacture wind blades of any design utilizing fiberglass, carbon fiber, and next-generation advanced materials. BladeAssure optimizes TPI’s production process by digitizing shop-floor workflows and automating real-time process monitoring, which enforces strict manufacturing compliance, reduces cycle times, and eliminates quality defects at the source.
The wind energy market demands agility. TPI’s production facilities feature highly flexible, precision molding and assembly systems. Utilizing cutting-edge modular tooling techniques, we can quickly and efficiently transition our manufacturing lines to produce different wind blade models and sizes based on evolving customer specifications.
To ensure seamless execution from blueprint to production, TPI utilizes a proprietary Model-Based Manufacturing (MBM) approach.
We have developed a dependable, highly scalable manufacturing method that allows us to repeatedly transition new products from the initial design phase into high-volume production. Whether launching in an established hub or a developing region, TPI maintains strict quality control worldwide.
As wind blade designs evolve, they place greater demands on advanced composite materials, fabrication processes, and quality assurance. TPI’s extensive experience in high-volume, high-quality wind blade production gives us a unique advantage in collaborative DFM.
At TPI, quality is non-negotiable. We employ a rigorous suite of advanced measurement, inspection, and non-destructive testing (NDT) technologies to guarantee absolute adherence to precise tolerances and strict quality standards throughout our entire production lifecycle. Our BladeAssure elevates quality assurance, inspection, and testing by digitizing compliance workflows and automating real-time process monitoring to validate structural integrity during production and eliminate defects before blades ever leave the factory.
Every component undergoes stringent testing procedures fully aligned with regulatory frameworks and specific customer standards. To maintain cutting edge dimensional tolerances across large-scale structures spanning 60 to 80+ meters, we leverage an advanced digital quality ecosystem. Central to this ecosystem is BladeAssure, our proprietary, data-driven monitoring platform designed to ensure the long-term structural integrity and performance of every blade we manufacture.
By combining world-class engineering with state-of-the-art metrology, TPI ensures maximum product integrity, optimal aerodynamic performance, and a lower total cost of ownership for wind energy operators.
Wind energy is set to supply over 30% of global electricity by 2050, growing from 1,000 GW in 2023 to nearly 8,000 GW. This rapid expansion presents a major opportunity for TPI Composites. Backed by global climate policies—including the U.S. Inflation Reduction Act and the EU Green Industrial Plan—governments are investing heavily in clean energy infrastructure. TPI is responding by scaling its manufacturing capacity, leveraging tax credits, and aligning production with regional demand. Through innovation, reliable delivery, and close industry collaboration, TPI remains a leading supplier in the global wind energy market.
Wind energy is expected to make up over 30% of electricity generation in 2050 with close to 8,000 gigawatts (GW) installed compared to approximately 1000 GW in 2023.4 This eight times increase in installations is a significant opportunity for the wind industry and TPI. Wind power, among other renewable energy sources, is now considered one of the most cost-effective methods for generating electricity in a majority of countries worldwide.5 As electrification and load growth become more urgent priorities, wind will play an important role in meeting expected increases in electricity demand in the coming years.
Governments continue to ramp up action on climate change, driving a surge in renewable energy adoption and emission reduction efforts. The landmark COP29 summit in Baku, Azerbaijan resulted in a financing commitment of $300 billion annually in support of developing countries addressing the impacts of climate change, increasing from an earlier $100 billion annual commitment.6 While more support may be needed over time, this significant increase was noted as a positive outcome of this year’s summit.
Wind project developers, investors, and manufacturers continue to take advantage of the support provided by the Inflation Reduction Act (IRA) of 2022 which allocated a historic $391 billion for clean energy and climate initiatives over the next decade. TPI is among manufacturers in the U.S. who have announced planned restarts of facilities to meet expected market demand for wind turbine components, and additional manufacturing capacity is being reviewed which would utilize the Advanced Manufacturing Production Tax Credit under the IRA. The investments underway and resulting job creation are expected to garner continued support for the IRA. This strategic approach aims to meet the projected demand of almost 10 GW per year for onshore wind by 2031.7
The EU Green Industrial Plan, adopted in 2024, aims to increase clean energy manufacturing and technologies across Europe. Backed by significant funding, including a €100 billion Industrial Decabonisation Bank, the plan focuses on simplifying permitting for renewable energy projects, increasing skill development for workers in greener industries, and promoting open trade to boost renewable energy across the continent. The EU’s goal for onshore wind remains 425 GW installed capacity by 2030.8
TPI continues to innovate and work closely with our customers, suppliers, and industry stakeholders to manage rapid change in the international wind market by adapting our global manufacturing footprint to best meet regional demand competitively. By supporting our customers’ workhorse platforms with consistent delivery and quality, and rapidly launching other blade models for opportunities in the U.S. and internationally, we unsure that TPI remains the preferred supplier to our customers.
