Mexico possesses one of Latin America’s largest energy systems, but its infrastructure is not evenly matched with the country’s changing economic geography. Electricity demand is growing in industrial regions near the United States, renewable resources are often located far from major consumption centres, and the south and southeast still require stronger access to reliable electricity and natural gas.
The country has extensive generation, transmission, distribution, pipeline, refining and port assets. The immediate question is whether these networks can be expanded quickly enough to support new factories, growing cities and a changing power mix.
Mexico’s infrastructure challenge is therefore less about creating a national system from the beginning than removing bottlenecks inside a system that already reaches almost the entire population.
Industrial Growth Has Turned Grid Capacity Into an Economic Issue
Manufacturing investment has increased the importance of electricity availability in Mexico’s northern and central states. Automotive, electronics, aerospace, appliance and data-centre projects require more than a basic connection. They need stable voltage, high-capacity substations, redundant supply and clear schedules for receiving power.
Many of the areas attracting investment are already major industrial centres. Nuevo León, Chihuahua, Coahuila, Querétaro, Guanajuato and the border cities contain dense clusters of factories and logistics facilities. New demand in these locations can place pressure on transmission corridors and local distribution systems even when Mexico has sufficient generation elsewhere.
This makes grid access part of the country’s competition for industrial investment. A company may choose a location based on transport links and labour availability, but the project cannot operate without a firm electricity connection. Delays in transmission or substation construction can therefore slow investment that has already secured land, financing and customers.
Renewable energy adds another geographic challenge. Mexico has excellent solar conditions in the north and northwest and major wind resources in Oaxaca and other regions. These resources are valuable only when transmission capacity allows their electricity to reach consumers.
The result is an infrastructure system that must serve two movements at once: rapidly growing industrial demand and a gradual shift toward cleaner electricity generation.
CFE Operates a Network of Continental Scale
The Comisión Federal de Electricidad remains the central institution in Mexico’s electricity infrastructure. It operates the national transmission and distribution networks and controls a large share of generation directly or through associated supply arrangements.
By the second quarter of 2025, CFE reported approximately 71,131 megawatts of generation capacity, a transmission grid of 111,178 circuit kilometres and a distribution network approaching 905,000 circuit kilometres. Its customer base had reached 49.4 million, with electricity coverage extending to 99.7% of the population.
These figures show the reach of the system, but national coverage does not guarantee equal service quality or available capacity. Rural electrification may involve relatively small loads, while a single industrial complex can require hundreds of megawatts and major new network works.
Mexico also contains areas that require distinct infrastructure planning. Baja California has electricity connections with the western United States but is not fully integrated with Mexico’s main interconnected system. Baja California Sur relies on an isolated network, while smaller communities and islands may depend on local generation.
Maintaining such a large and varied system requires continuous investment in transformers, feeders, substations, control equipment and emergency response. Much of the public discussion focuses on new power plants, but the electricity produced by those plants has limited value unless the grid can deliver it reliably.
The 2025–2030 Plan Places Transmission at the Centre
The Mexican government has responded with a large transmission expansion programme. Under the 2025–2030 Strengthening and Expansion Plan, CFE intends to build 275 new transmission lines and complete 524 works involving electrical substations. The announced investment exceeds US$8.1 billion and is intended to strengthen supply for around 50 million users.
The programme is important because transmission projects have long development periods. Routes must be selected, land and rights of way secured, environmental and social reviews completed, equipment ordered and connections coordinated with the wider network.
New lines will be needed in several types of location. Northern industrial corridors require more capacity to serve manufacturing growth. Renewable regions need routes to electricity markets. The Yucatán Peninsula and southeastern states require reinforcement to improve reliability and support new economic activity. Urban areas need substations and distribution upgrades as electricity use becomes more concentrated.
CFE also plans wider distribution investment, including new substations, upgraded transformers and feeders, conventional rural networks and individual solar systems for locations where grid extension is difficult.
The scale of the programme reflects a basic change in national planning. Electricity infrastructure is no longer treated only as a public service requirement. It is also being positioned as an industrial-development tool.
Natural Gas Pipelines Support Much of the Power System
Mexico’s electricity network depends heavily on natural gas infrastructure. Combined-cycle plants provide a large share of generation, and many use gas imported by pipeline from the United States.
U.S. pipeline exports to Mexico reached an average of 6.4 billion cubic feet per day in 2024. This trade gives Mexico access to abundant and competitively priced gas, but it also creates exposure to events outside the country. Severe weather, pipeline constraints or market disruption in the United States can quickly affect Mexican power plants and industrial consumers.
The gas network is better developed in northern and central Mexico than in some southern regions. Expanding supply toward the southeast has therefore become a major infrastructure priority.
The Puerta al Sureste pipeline is one of the most important recent projects. The 715-kilometre system runs mainly offshore from Tuxpan, Veracruz, toward Coatzacoalcos and Paraíso. It can transport approximately 1.35 billion cubic feet of gas per day and is designed to supply power generation and industry across the southeast and Yucatán Peninsula.
The pipeline connects with the Sur de Texas–Tuxpan system, meaning much of its gas can originate in the United States. It is expected to support around 1.5 gigawatts of electricity generation while replacing more expensive and higher-emission fuel oil in some plants.
This improves regional fuel access, but it also deepens the relationship between Mexico’s electricity system and North American gas infrastructure. Long-term security will depend on pipeline redundancy, storage, domestic production and the ability to manage interruptions.
The North-South Infrastructure Gap Remains Significant
Mexico’s energy map reflects different stages of industrial and infrastructure development. Northern states benefit from proximity to U.S. gas supplies and major manufacturing markets. Central Mexico has the country’s largest urban and industrial load centres. The southeast contains important oil and gas production, refineries and ports but has historically faced weaker access to some forms of modern energy infrastructure.
Projects such as Puerta al Sureste, new combined-cycle plants and transmission reinforcement are intended to narrow this gap. They also support wider development plans around the Interoceanic Corridor of the Isthmus of Tehuantepec and proposed industrial zones in southern Mexico.
The challenge is that infrastructure development must extend beyond headline projects. A major gas pipeline can improve regional supply, but industrial users also need local distribution networks. A new power plant requires transmission and substation capacity. A logistics corridor needs reliable electricity at ports, rail terminals, warehouses and production sites.
Infrastructure must therefore be planned as a connected system rather than as isolated assets.
State Leadership Will Define the Pace of Expansion
Mexico’s current electricity policy gives CFE a dominant role in planning and investment. The national framework calls for the state utility to retain at least 54% participation in electricity generation while private investment continues through long-term contracts, mixed projects and participation in the wholesale market.
This model places considerable responsibility on CFE. The company must expand public infrastructure, finance large projects, maintain existing assets and coordinate private generation connections. Private developers may add capacity, but transmission and distribution remain public networks.
The structure can support coordinated national planning, especially where projects have social or regional objectives that may not attract private investment by themselves. It can also create execution risk if public budgets, procurement processes or project approvals delay necessary construction.
Mexico has already achieved near-universal electricity access and built an extensive North American gas network. The next phase is more demanding because it requires capacity to be added in specific places at the time industry needs it.
Mexico’s Energy Future Depends on Delivering the Network
Mexico’s energy infrastructure is large enough to support a major industrial economy, but its next stage of growth will depend on targeted expansion rather than national coverage alone.
Transmission must connect new generation with industrial demand. Distribution systems must accommodate large customers and growing cities. Gas pipelines must reach regions that still depend on less efficient fuels. Isolated systems require solutions suited to their geography, while cross-border energy links must remain reliable.
The 2025–2030 investment programme provides a clear direction. Its effect will depend on construction speed, financing, rights of way and coordination between power plants, pipelines and local networks. Mexico does not lack energy resources or major infrastructure assets. Its central task is to deliver additional capacity where economic growth is occurring before network limitations become a lasting barrier.
