What Cetasa does
Compañía Eólica de Tierras Altas SA (CETASA) is a Spanish wind energy generation company headquartered in Soria that operates four wind farms — Parque Eólico de Oncala, Magaña, Castilfrío, and El Cayo — in the Tierras Altas region of Soria province. The portfolio, among the earliest commercial wind installations in Spain, totals 100 MW of installed capacity across 132 horizontal-axis turbines brought online between 2001 and 2004, using NegMicon NM/750 and NM/900 units on the older sites and Made AE52 800 kW turbines on the two newer sites. CETASA's primary commercial relationship is the wholesale sale of generated electricity into the Spanish national grid operated by Red Eléctrica de España, under regulated or contracted supply arrangements; the company has no consumer-facing product and no publicly disclosed pricing model.
CETASA's technology stack combines the legacy turbine fleet with a proprietary monitoring layer: the SEPE system, developed in collaboration with Fundación CIRCE, provides real-time wind farm tracking, power curve analysis, and turbine availability control. The CMI (Centro de Mantenimiento Integral) in San Pedro Manrique, a €2.5 million facility, functions as the integrated operations and maintenance hub, housing an electrical magnitude laboratory, training resources, and a shared ecosystem of more than 40 companies including OEMs, universities, and research institutions. Day-to-day O&M is delivered through permanent partnerships with Vestas and Siemens Gamesa Renewable Energy, supported by a permanent team of more than 20 professionals that expands to 40+ during peak summer maintenance campaigns.
The business model is a single-revenue-stream wholesale generation model with revenue tied to megawatt-hours delivered to the grid and to the prevailing Spanish power price or regulated tariff regime. As of July 2025, Enel — through Endesa — acquired 100% of CETASA's capital, fully integrating the company into the Enel corporate structure after a period of joint ownership with Caja Rural de Soria and Caja Rural de Navarra. Headcount at the corporate level is reported at 1–10, consistent with a lean operating entity that relies on contracted O&M and group-level support from Enel rather than a vertically integrated utility staffing model.
