Wind power plants in Oaxaca, Mexico


The Mexican Government has been working on the construction of a mega structure generating wind power in the State of Oaxaca since 1994. Indigenous peasants resident in the area claim that the 3,000 concrete pillars envisaged by the project have caused forced displacement of numerous families, have destroyed the ecosystem in one of the most important areas for migratory birds and will contaminate the surrounding water.

The projects Piedra Larga I and II, owned by DEMEX, are being denounced by Union Hidalgo since they were deployed without the consultation of the native people living in the area and without prior studies on the environmental and urban impacts. They are situated very close to the inhabited areas, having disastrous consequences on the agricultural production of the communities.

On September 5th 2014 a march was organized in Juchitán to which smaller towns of the Tehuantepec isthmus joined as well, defending the land against the multinationals’ appropriation. A year later, in September 2015 the indigenous community Zapoteca reported irregularities and human rights violations in the consultation process which asserts communities’ agreement for new wind-power plants in Juchitán and El Espinal, which is endorsed by the Energy Secretary SENER, by the Oaxaca State and by the local government of Juchitán.

Project Details and Actors

Project details

The first wind project, La Venta I, began operating in 1994, and was followed two years ago by La Venta II, inaugurated in 2007: it has 98 aero-generators with a total capacity of 83.3 MW. The plant is built by the Spanish multinational companies Iberdrola and Gamesa and managed by the CFE. In 2007 the Government of Felipe Calderon announced open bidding for La Venta III, and that other wind-energy projects will follow, e.g. the Oaxaca and La Ventosa projects. By 2007, 98 aero-generators had been installed covering an area of 650 hectares.

The Piedra Larga 1 is a 90 MW wind-farm, comprising 145 wind turbines and in operation since October 2012. Still under construction, Piedra Larga 2's objective is to achieve 138 MW capacity. The future considered mega- project in Juchitán is expected to generate 396 MG.

Other socio-economic impactsOpponents to the wind park argue that these lands are in fact suitable for cultivation and that, until now, the project has not bought any economic benefits; land rental rates are very low and do not generate much income, and the energy supply has not improved, considering many houses do not have electricity.
