Oaxaca II-III-IV Wind Complex
The largest wind power complex in Latin America, it is made up of 204 AW1500 wind turbines, which generate enough energy to power 700,000 Mexican homes.
The Wind Complex consists of the Oaxaca II, Oaxaca III and Oaxaca IV wind farms, all of them including AW1500 wind turbines, of 1.5MW rated capacity each. Located in the Isthmus of Tehuantepec, between the Atlantic and Pacific Oceans, a site with an exceptional wind resource, it produces around 1,129 GWh a year, equivalent to the power demand of 700,000 homes. It is owned and operated by ACCIONA Energia.

Overcome challenges
Foundations
Construction on sites with low supporting capacity, so it was necessary to apply a range of foundation solutions according to each location
Weather
The high wind speeds meant that assembly had to be planned on the basis of very short periods to take advantage of the ‘windows’ of low speeds.
Purchases and logistics
The purchases and logistics associated with the supply of materials such as concrete, steel, wiring and other main components was directly managed by ACCIONA
