The La Mata Ventosa wind farm will have a capacity of 67.5MW and is EDF's first wind project in Mexico. It is located in the Tehuantepec isthmus, where all four of the country's 2009 wind farms were based.
Clipper Windpower is to supply 27 2.5MW turbines for the site. Clipper and EDF subsidiary enXco will be responsible for operations and maintenance.
EDF said it has signed a 15-year supply agreement with Walmart Mexico. The deal was been done under Mexico's self-supply rules, which allow the purchaser to take as much electricity from the grid as they are putting back in.
Self-supply power contracts enable wind developers to circumvent rules prohibiting private investment in power generation for general supply to the national grid and are proving to be a novel way to bring new wind online.
