TPI Composites, Inc. designs and manufactures advanced composite wind blades for the global wind energy market. Founded in 1968 and headquartered in Scottsdale, Arizona, the company operates manufacturing facilities across the United States, Mexico, and India, alongside advanced engineering centers in Denmark and Germany. In 2024, TPI produced 6,525 wind blades and captured approximately 27% of the global onshore wind blade market by megawatts, excluding China. The company generated $1.3 billion in net sales and employs over 14,000 associates across more than 6 million square feet of manufacturing operations.
TPI manufactures composite wind blades to precise specifications for wind turbine manufacturers and delivers complementary services including preventative maintenance, inspections, repairs, and improvements for existing installations. The company operates global service training centers in multiple countries and maintains advanced engineering capabilities to support its core manufacturing operations. Wind blades produced in 2024 are projected to prevent over 264 million metric tons of carbon dioxide emissions over their 20-year operational lifespan, equivalent to the electricity use of more than 55 million U.S. homes for one year.
The company traces its origins to Tillotson Pearson Inc., which specialised in high-performance composite structures for marine applications and industrial use before transitioning to wind blade manufacturing in 2001. TPI positions its manufacturing footprint to minimise total delivered costs whilst maintaining production quality and engineering expertise.
