SENER Identifies Transmission as a Binding Constraint

At the ITA-LAC 2026 forum, Jorge Islas Samperio, Deputy Minister of Energy Planning and Transition at SENER, firmly stated that Mexico faces no electricity shortage, clarifying that recent blackouts across 20 states stem from transmission and distribution network bottlenecks rather than an insufficient generation capacity. To systematically address these network constraints and accommodate growing load center demands, the Sheinbaum administration is rolling out a massive US$50 billion investment framework. The comprehensive strategy allocates US$30 billion for new generation projects, US$10 billion for transmission infrastructure, and up to US$4 billion to reinforce distribution grids, aligning with calls from industrial developers and nearshoring sectors who identify grid interconnection speed as Mexico’s true energy bottleneck.

Jorge Islas Samperio, Deputy Minister of Energy Planning and Transition, SENER, stated at the ITA-LAC 2026 forum that Mexico will have sufficient electricity to meet demand, and that the problems registered in recent months do not stem from insufficient generation capacity but from limitations in transmission and distribution networks. "There will be no energy shortage; if there are some problems right now, they are network problems that we are solving. We have very dynamic planning that we update every year," Islas said.

The statement is the federal government's most direct public response yet to a sustained national debate about electricity outages that have affected at least 20 states during the 2026 summer demand season, including documented incidents in Chihuahua, Nuevo Leon, Coahuila, Cancun, Puebla, Hidalgo, and Veracruz.

The Official Diagnosis: Generation Is Not the Problem

As reported by Expansión, Islas explained that the evaluation is carried out node by node across the country to detect the regions where supply restrictions could occur and plan the transmission and distribution works that would allow available energy to be evacuated. As part of that strategy, the government is contemplating investments exceeding US$50 billion to strengthen the National Electric System: approximately US$30 billion for new generation projects, US$10 billion for transmission infrastructure, and between US$3.5 billion and US$4 billion for distribution network reinforcement. "With that annual planning, and those investments that we already know where to make, we want to build an electricity sector that feels secure. Mexico will have energy, but above all there will be clean energy," Islas said.

The official also noted that companies seeking to increase their consumption of electricity from renewable sources will be able to certify its origin through Clean Energy Certificates (CEL), providing traceability to the energy used in their operations.

The Generation-Transmission Disconnect

CFE has an effective capacity of 62,712MW, despite having an installed capacity close to 90,000MW. For this summer, maximum electricity demand is estimated at 55,600MW, which would leave an operational reserve margin above 9%.

The gap between installed capacity and effective capacity is the operational expression of the problem Islas is describing. Not all installed generation capacity is dispatchable at any given moment, maintenance commitments, fuel supply constraints, grid connection limitations, and the intermittency of renewable sources all reduce effective capacity below the nameplate total. The 9% reserve margin that results from comparing effective capacity against peak demand is adequate on paper, but it disappears rapidly if transmission bottlenecks prevent generation from reaching load centers at the required moment.

President Sheinbaum has herself acknowledged that the recent interruptions reflect distribution network failures rather than generation insufficiency, stating: "Blackouts are for a long time and mean lack of generation capacity; these are service interruptions in some places, the product of distribution failures rather than generation; that is, there are not enough lines to distribute the energy. So, blackouts mean there is not sufficient generation capacity for demand, and that does not exist in Mexico."

Although Mexico today has greater availability of generation plants compared to prior years, and CENACE advanced maintenance schedules to conclude before the summer, transmission infrastructure remains one of the main bottlenecks. CFE reported that in 2025 it concluded 19 transmission projects that incorporated 384 kilometers of new electrical lines, with the objective of strengthening the network's capacity, maintaining voltage stability, and improving National Electric System reliability.

What the Investment Plan Addresses

The US$50 billion investment framework Islas outlined at the ITA-LAC forum is the most comprehensive public figure the Sheinbaum administration has attached to the full electricity sector investment program, encompassing the US$30 billion generation component, US$10 billion in transmission, and the US$3.5 to US$4 billion distribution allocation. The transmission and distribution components together represent approximately 27% of the total, a proportion that is broadly consistent with independent analyses identifying the transmission gap as the primary binding constraint on Mexico's electricity reliability.

The Institute of the Americas' recent report on data centers and energy identified grid connection speed, not generation capacity, as the binding constraint on Mexico's digital infrastructure development, with more than 1,500MW of data center capacity announced but only 244.9MW actually connected. AMDEE's wind industry seminar in late June reached the same conclusion from a developer's perspective: timely transmission investment is the non-negotiable catalyst for converting the 7,411MW mixed development scheme award and the 13 new wind parks in the pipeline into operating, revenue-generating assets.
