On December 21, 2013, Mexico’s sweeping and historic energy reform bill formally became law. On August 12, 2014, a package of energy reform legislation became law in Mexico, which includes nine new laws as well as amendments to existing laws, implements the December 2013 constitutional energy reform and establishes a legal framework for Mexico’s energy industry.


Mayer Brown has significant experience in Mexico, demonstrated by the many types of deals represented below. Our experience in developing and financing power projects in Mexico includes both renewable and traditional power projects financed by export credit and other bilateral agencies, multilateral agencies, commercial banks and project bonds. We have experience that extends back to the inception of the Mexican independent power producer program and self-supply regimes for electrical power generation. And that experience continues: this year we represented the sponsors in the successful closing of the El Porvenir 54 MW renewable energy self-supply project.

Additionally, we maintain excellent relations with leading Mexican law firms and are accustomed to providing seamless representation in concert with them.
