Mexico approves solar permits for 649 MW with battery storage

Mexico’s National Energy Commission has approved six solar generation permits that will add 649 MW of net capacity to the national grid. The projects, which will include battery energy storage systems, represent an estimated investment of $750 million and are scheduled to enter operation in 2028 and 2029, SENER said.

The authorizations come from SENER’s second call for priority processing of generation and interconnection permit applications, carried out under Mexico’s binding planning framework. The process began with 223 registrations, of which 71 paid for or revalidated interconnection studies. Of the 57 permit applications ultimately received, six were approved, with results published Nov. 6.

SENER’s official list identifies the approved applications by file number but does not name the permit holders. Bloomberg Línea reported that Green Park Energy, part of the Cox group, obtained three permits; Ammper Generación, owned by Invex Controladora, received two; and Viva el Sol obtained the remaining one.

Green Park Energy’s three plants will be located in Aguascalientes, Jalisco, and Guanajuato, Ammper Generación will develop projects in Tlaxcala and Morelos, and Viva el Sol will build its plant in Coahuila, the outlet reported. The permits, granted Nov. 5, cover generation projects selling into the wholesale electricity market.

Of the authorized capacity, 350 MW will connect in the Western regional control area of the national grid, 289 MW in the Eastern area, and 10 MW in the Northeastern area. SENER said it expects 37% of the approved capacity to enter operation in 2028 and the remaining 63% in 2029.

All six projects will include battery storage. The plants total 751.08 MWac of declared solar capacity and 204.38 MW/627.94 MWh of storage, according to technical data published by Spanish-language trade outlet Energía Estratégica. These figures differ from the 649 MW of net capacity reported by the government because they correspond to different project parameters.

The approval follows the first call for private developer permits, resolved in December 2025, and forms part of the process through which the Mexican government seeks to add new generation in line with regional interconnection needs. SENER said projects not selected may take part in future calls or continue through the conventional process.
