Mexico's New Energy Storage Regulations Require 30% Battery Storage in Solar and Wind Projects, Aiming to Add 574MW of Storage Capacity by 2028

 

The Latin American Energy Organization (LAEO) released a white paper on energy storage in Latin America and the Caribbean, noting that Mexico has enacted unique regional regulations requiring solar and wind power plants to be equipped with battery systems equivalent to 30% of their installed capacity, with a target of adding 574 MW of energy storage capacity by 2028.

 

The white paper cites Mexico as an example of gradual integration. The regulations specify five energy storage models: integrated with renewable energy power plants, load centers, stand-alone systems, distribution networks, and microgrid off-grid systems. These systems enjoy grid connection rights, licensing qualifications, and eligibility to participate in the energy and ancillary services markets.

 

According to the regulations promulgated in March 2025, all new solar and wind power projects must be equipped with battery systems equivalent to 30% of their installed capacity, with a minimum continuous power supply duration of 3 hours. This measure will drive an additional 574 MW of battery energy storage systems by 2028, enhancing the operational efficiency of the national power system and optimizing the management of renewable energy intermittency.

 

Energy storage systems integrated with renewable energy power plants primarily control power generation fluctuations, meet peak demand, and comply with system dispatch instructions. Load center energy storage, deployed by industrial and commercial users, aims to optimize load and reduce peak demand. Stand-alone system energy storage, as an electrical asset, provides ancillary services such as frequency regulation and voltage control. Distribution network energy storage strengthens substation and line infrastructure, improves power quality, and reduces technical losses. Microgrid off-grid system energy storage ensures power continuity in remote areas and reduces reliance on diesel generators.

 

Mexico's National Electricity System Development Plan (2024-2038) lists energy storage as a strategic component for grid stability, projecting the deployment of 8.4 gigawatts of energy storage systems by 2038 to support intermittent power source grid connection. Through specific regulations, mandatory requirements for renewable energy-integrated energy storage, and long-term planning, Mexico is becoming a benchmark case for energy storage development in Latin America.
