What Windar renovables does
Windar Renovables, S.A. is a Spain-based industrial manufacturer of tubular steel structures for the wind energy sector, founded in 2007 in Asturias as part of the Grupo Daniel Alonso conglomerate. The company produces three core product lines: onshore wind turbine towers, offshore wind turbine towers, and offshore substructures including monopiles, jackets, and transition pieces. Its core technical capability is XXL-scale fabrication — monopiles up to 12.5 metres in diameter, 3,500 tonnes, and 130 metres in length, and offshore tower sections up to 320 tonnes — supported by an in-house R&D center (Windar Technology and Innovation, est. 2020) with 20+ engineers covering structural calculation, welding, manufacturing engineering, and process digitalization.
The company operates 10 manufacturing locations across six countries (Spain, France, India, Brazil, Mexico, Poland), with major facilities in Avilés (HQ), Fene (Navantia JV for monopiles), Linares, Altamira/Mexico, and two new Polish plants under development in Szczecin (offshore towers, production from 2026) and CTPark Legnica (onshore towers, late 2026). Its revenue model is project-based direct B2B manufacturing for enterprise customers under negotiated, non-disclosed contracts. The customer base is highly concentrated among tier-one offshore wind developers and OEMs — primarily Iberdrola (strategic collaboration exceeding €1 billion over 10 years), Siemens Gamesa (e.g., 90 towers for Coastal Virginia Offshore Wind), Ocean Winds, and Vestas. Pricing is project-by-project, with the WindarMex plant holding a unique position as the only facility in the Americas capable of manufacturing large offshore towers.
Windar is currently in a heavy expansion phase, committing approximately €130 million to a new monopile factory in Avilés (600 new jobs), building new offshore and onshore tower capacity in Poland, and upgrading WindarMex for offshore production. The business is privately held under Grupo Daniel Alonso with no public revenue disclosure; financing to date includes a €41.5 million sustainable facility from Banco Sabadell Herrero (2022). Certifications across all global sites include ISO 9001 (quality) and ISO 27001 (information security).
