Mexico's 2010 national energy strategy aims to promote sustainability and simultaneously increase energy access by increasing the share of renewable resources used to generate energy. The wind farms of La Ventosa, a windy area in the southeastern state of Oaxaca, are a key part of that strategy, which aims to raise the share of renewables in generation to 35 percent by 2024, up from 23.7 percent in 2008. The open season process was a major breakthrough that made possible several agreements to build wind power generation projects in an area that previously had been closed to development because of the lack of transmission infrastructure. The open season process gave developers of renewable energy the certainty and predictability they needed concerning the development of transmission infrastructure, while also reducing the investment costs of that infrastructure by ensuring development of an optimized and shared network. Moreover, the system is transparent for all participants. It highlights the ability of Comision Federal de Electricidad (CFE) to modernize its role as a facilitator and creative problem solver, and encourages renewable energy developers and energy consumers to collaborate and follow through on their commitments for the benefit of all involved.
