The Invisible Limit of Nearshoring: Energy Is Becoming Mexico’s Main Bottleneck
Without new generation, grid upgrades, and storage, electricity demand could outstrip the country’s capacity and raise production costs—hurting investment and growth.
Mexico’s economy is trying to capitalize on one of its most promising moments in years: the reshoring of supply chains to North America, a manufacturing expansion, and the arrival of new data centers. However, as investment announcements multiply, a constraint that is no longer theoretical is also growing: the availability of electricity and the fuels needed to generate it. The power system, which for decades kept pace with growth with relative slack, now looks like a factor capable of delaying projects, raising costs, and eroding competitiveness.
Estimates from the Mexican Institute for Competitiveness (IMCO) warn that by 2030 Mexico could face a generation shortfall of more than 48,000 GWh even under conservative scenarios. In practical terms, that gap would mean less capacity to power new industrial plants, expansions of manufacturing hubs, and the gradual electrification of processes that previously depended on fossil fuels. In an environment where the decision to locate a factory is based on costs, certainty, and time to connect to the grid, energy is starting to work against Mexico.
The problem isn’t limited to “building more plants.” The strain shows up in tight reserve margins, greater sensitivity to heat waves, and cost volatility when supply doesn’t grow at the same pace as demand. S&P Global has noted that the country needs to add on the order of tens of thousands of megawatts in the coming years, along with significant investment in transmission and distribution. The scale of that effort comes at the same time the Federal Electricity Commission (CFE) faces budget constraints and a meaningful financial burden—making the role of private capital and public-private investment structures both decisive and a point of debate.
For the economy, the risk is clear: if electricity becomes more expensive or less reliable, manufacturing loses its relative appeal versus other destinations. This is happening at a time when Mexico remains tightly integrated with external demand—particularly with the United States—so any logistical advantage from nearshoring can be diluted if energy infrastructure doesn’t keep up.
Imported Natural Gas: A Cost Advantage, an Operational Vulnerability
Mexico’s power mix relies predominantly on natural gas: according to official data, a majority share of generation comes from this fuel, and a large portion of the gas consumed in the country is imported from the United States. That relationship has served as a cost anchor thanks to abundant gas in regions like Texas, but it has also cemented a vulnerability: Mexico has limited storage capacity to withstand temporary disruptions, maintenance, weather events, or logistics failures.
In practice, low energy inventories limit room to maneuver in contingencies. In a power system with tight reserves, a stress episode—for example, high summer demand or an interruption in gas supply—can translate into higher costs, operational adjustments in industry, and price pressures. For companies, the discussion stops being abstract and becomes a basic question: Will there be enough energy, at a competitive price, over the next 10 or 20 years?
The debate over alternatives—such as developing domestic reserves or more intensive extraction technologies—often runs into long timelines. Even if projects are accelerated, results are rarely immediate: production, transport, and storage infrastructure requires years of investment, permitting, and execution. For that reason, the most feasible short- and medium-term solution tends to focus on expanding and modernizing the electric grid, unlocking new generation plants, and improving system flexibility through storage, maintenance, and responsive capacity.
The macroeconomic dimension also matters. Energy is an economy-wide input: when its cost rises or becomes uncertain, it affects everything from the auto and auto-parts industry to electronics, mining, and technology-intensive services. A persistent increase in energy costs can fuel inflationary pressures and squeeze business margins, impacting investment and employment. In addition, a lack of capacity can reshape the nearshoring map: states with better access to energy and water attract more projects, while others fall behind even if they have labor or a strong logistics location.
In this context, Mexico’s growth outlook looks moderate. Various organizations have projected expansions below the pace needed to sustainably raise productivity. The Organisation for Economic Co-operation and Development (OECD) has pointed out that closing infrastructure gaps is key to raising potential growth, and energy stands out as one of the most urgent bottlenecks because of its direct effect on manufacturing, investment, and competitiveness.
Looking ahead, the discussion will focus on three fronts: regulatory certainty to spur investment, technical planning to prioritize grid projects where congestion is already evident, and an energy security strategy that reduces fragility to disruptions. For Mexico, the nearshoring window is not infinite; if energy infrastructure doesn’t accelerate, the opportunity could shift to other markets with greater installed capacity and shorter grid-connection timelines.
In short, energy is becoming the most visible structural limit on growth—not only because Mexico needs to generate more electricity, but because it urgently needs to modernize the grid, increase reserves, and provide investment certainty. If the country can solve that bottleneck, industrial potential can expand; if not, the cost will be slower growth and more fragile competitiveness.
