Oaxaca II, III and IV represent one of the biggest wind power complexes in Latin America with 306 MW of operational capacity. They produce electricity to cover the consumption of 700,000 Mexican homes, avoiding the emission of 670,000 metric tons of CO2, equivalent to the cleaning effect of 33.5 million trees on the atmosphere through the process of photosynthesis.

ACCIONA is the leader in wind power in Mexico with 556.5 MW spread across four wind farms, the three mentioned above and Eurus (250.5 MW). The company has also built a 252MW wind power complex in Nuevo Leon and a 49,5MW wind farm in Oaxaca for third parties

Key Points

Installation of 204 wind turbines
Complex consisting of three wind farms (102 MW each - Oaxaca II, Oaxaca III and Oaxaca IV)
34.5 km of access roads/tracks
350 km of underground cables
49 km power transmission line (230 kV)
Construction on sites with very low bearing capacity, so it was necessary to apply a range of solutions for the foundations, depending on the location
High wind speeds meant that the assembly had to be planned in very short periods to take advantage of low wind speed ‘windows’
The purchasing and logistics for the supply of materials such as concrete, steel, cables and other main components was directly managed by ACCIONA.
Wide-ranging program of socio-economic development in the local community.
