Mexico selected 7,410 MW of utility-scale solar and wind projects in June from nearly 38,000 MW of proposals, under the revamped energy policy framework set in motion by President Claudia Sheinbaum, according to IEEFA.
Solar photovoltaic took the bulk of the awards at about 6,700 MW, with the remaining 700 MW going to wind, IEEFA reported.
Every selected project must be built with battery storage equal to at least 30% of its capacity, with a minimum duration of three hours, under the new rules. The storage mandate applies across the awarded portfolio rather than to a subset of sites.
The awards sit inside a wider government ambition to add roughly 20,000 MW of renewables and 5,000 MW of battery storage by 2030, according to IEEFA.
That target runs against a generation mix still dominated by hydrocarbons. Oil, gas, and coal produced nearly 80% of Mexico's power between 2000 and 2024, IEEFA said.
The internal composition of that fossil share shifted sharply over the period. Gas-fired power climbed from 22% of generation in 2000 to 62% in 2024, while oil's contribution dropped from 45% to just over 7%, according to IEEFA.
Net electricity generation in Mexico totaled 352,305 GWh in 2024, according to data from the Mexico Ministry of Energy cited by IEEFA. Measured against that output, the selected capacity and the 2030 build-out target set the scale of what the policy reset is attempting on a system where gas has replaced oil as the dominant fuel rather than ceding ground to renewables.
The pairing requirement is the structural feature that separates this round from a straightforward capacity award. By tying each megawatt of solar or wind to at least three hours of battery duration at 30% of nameplate capacity, the framework pushes storage procurement in step with generation rather than as a later retrofit. The 5,000 MW storage figure in the 2030 goal is roughly a quarter of the 20,000 MW renewables figure attached to it.
The gap between the nearly 38,000 MW proposed and the 7,410 MW selected indicates developer appetite well beyond what the June round accommodated.
