The Federal Electricity Commission (CFE) presented the 2025-2030 Expansion Plan with an investment of 163,540 million pesos , which includes the construction of 275 new transmission lines equivalent to 6,735 circuit kilometers and 524 substations throughout the country.
The goal is to overcome the main obstacle to the growth of renewable energy and industrial development: the lack of transmission infrastructure. According to the National Electricity System Development Program (PRODESEN) 2024-2038 , Mexico requires at least 15,000 additional kilometers of new lines if it aims to integrate between 15 and 20 GW of renewable generation by 2030 .
In this context, the CFE's announcement responds to a strategic urgency to ensure the system can transmit wind and solar energy from regions with high potential to major consumption centers. During the presentation, Emilia Calleja Alor, Director General of the Federal Electricity Commission (CFE), stated: "We cannot leave this in private hands because the reliability of the system is at stake." Mayor Claudia Sheinbaum emphasized that this effort will consolidate a truly national system: "Now, the entire country is interconnected with this system," referring to the link between the Baja California peninsula and the rest of the nation. Currently, Mexico has more than 111,000 kilometers of transmission lines and 2,300 substations , but many are saturated or require modernization.
Calleja Alor explained that the expansion aims to "extend the grid and improve access to energy, decongest the existing infrastructure, and modernize transformers to provide greater efficiency and safety ." The plan will benefit more than 50 million users , which is equivalent to supplying energy to 15.5 million homes , or to powering more than 8,000 medium-sized factories .
The strategy includes 92 projects in the northern region , where 23 projects have already been completed and 137 lines and 247 substations are planned. "We are strengthening development towns, industrial corridors, and tourist centers ," explained the CFE director. In the central region, 49 projects will be developed, with 90 lines and 181 substations, which will "protect industrial corridors and prevent saturation and losses."
Meanwhile, in the southern region, 30 projects will be deployed, comprising 48 new power lines and 96 substations, aimed at meeting the demand in Veracruz, Oaxaca, and Chiapas —regions with strong wind and solar potential. "We are bringing energy to one million homes and strengthening the supply to tourist and industrial areas of the Isthmus and the peninsula," Calleja Alor explained. Technological modernization will be a key focus. "We are implementing state-of-the-art technology to reduce losses and congestion on the grid," he noted.
The strategy includes the installation of digital transformers, mobile sensors, remote monitoring systems, drones, and fiber optics over more than 15,000 kilometers .
Furthermore, a smart grid is being developed that can automatically adjust power flows according to demand. The plan also has a strong energy security component. "We are working every day to consolidate our energy sovereignty with a vision for the future, putting the public interest at the center of our actions ," stated the CFE.
President Sheinbaum added: "These are 275 projects for new lines and substations; it's a very important investment to connect the country and guarantee fair rates . The lack of transmission infrastructure has hindered the entry of renewable energy projects in Mexico."
The Isthmus of Tehuantepec has installed wind power capacity that cannot be evacuated to the south-central region due to a lack of interconnection nodes, while the northeast and northwest concentrate solar and wind resources that have not yet been fully integrated into the system.
With this plan, the CFE (Federal Electricity Commission) assures that "all available energy will be transported to where it is needed , aiming to reduce energy poverty and enable industrial development hubs. The initiative represents the largest expansion of the transmission network in decades and aims to support Mexico in meeting its energy transition goals by 2030. "We are working fully and with great responsibility to guarantee that energy is provided continuously and with increasingly cleaner energy ," concluded the CFE management.
