After a sharp drop in spending by Mexico’s federal power utility, concerns are growing about the country’s electricity network. CFE’s investment in new projects fell by nearly a quarter in 2025, slowing the expansion of power plants and transmission lines. Now, industry experts warn that the grid could struggle to keep up with surging demand. Could more power outages be on the horizon, or will new plans come to the rescue? The coming years will reveal if Mexico can shore up its grid — or face growing reliability challenges.
Investment Falls to Historic Lows
The Federal Electricity Commission (CFE) — Mexico’s state-run power company — saw its physical investment budget shrink dramatically last year. According to newly released Finance Ministry data, CFE spent about 46.6 billion pesos (roughly $2.5 billion) on electricity infrastructure in 2025. That figure represents a 24% decline in real terms from the previous year’s spending. In fact, it marks the smallest annual investment for the start of a six-year administration in decades, underscoring how sharply the utility’s capital outlays have dropped.
Industry analysts trace this slump to a project pipeline that has failed to keep pace with the country’s needs. The previous federal administration (2018–2024) made historically low investments in new-generation capacity, grid expansion, and major maintenance. By the end of that period, fewer power plants and transmission projects were underway than Mexico required. “We came off a six-year term with investment at a historic low, especially in transmission and big maintenance,” noted Carlos Flores, an independent energy analyst. The result is a backlog of upgrades and expansions that were delayed or never started. Now, the consequences of those years of underinvestment are coming due, as the new administration grapples with rising electricity demand but limited new infrastructure to meet it.
Strain on a Growing Grid
The sharp cutback in spending raises red flags about the reliability of Mexico’s power supply going forward. Experts warn that CFE’s reduced investments leave the electrical system more vulnerable to spikes in demand and extreme weather events. Last year provided a stark preview: during an unusually intense summer heat wave, millions of Mexicans cranked up air conditioners and fans, pushing electricity consumption beyond what the grid could supply. In several regions, the company had to resort to rolling blackouts — temporary, scheduled power cuts — because generation couldn’t keep up with the record demand.
Another dramatic incident underscored the grid’s fragility. In March 2025, a major outage left much of Cancún and the Yucatán Peninsula in the dark. Hotels, airports, and businesses were stranded without power for hours. While the blackout was initially attributed to a single substation failure, it revealed a deeper problem: there were few alternative routes to reroute electricity once that key hub went down. In effect, the network lacked the resilience to absorb a shock and keep power flowing. “If expansion of capacity and the network doesn’t keep up with demand, the risk is clear,” Flores warned. Without timely upgrades, he explained, outages could become more frequent, and the utility might be forced to lean on older, inefficient power plants to bridge the gap. That in turn raises generation costs and emissions, and it could even deter companies from expanding in Mexico if they worry the lights won’t stay on.
Worries for Industry and Growth
Mexico’s booming industrial growth amplifies the urgency of the issue. Manufacturers drawn by nearshoring opportunities, as well as energy-hungry data centers, are setting up operations across the country. All of them require reliable electricity. Yet the lag in grid development means some new facilities can’t get adequate power from the grid when they need it. In one high-profile example, Microsoft reportedly had to run a newly built data center in central Mexico on gas-fired generators because the local grid connection was not yet available. According to filings the company made with regulators, the required transmission upgrades wouldn’t be completed until mid-2027, forcing the data center to rely on its own generators in the meantime. Microsoft’s case may be extreme, but it highlights a trend: some large investors are having to secure their own power sources, at least temporarily, because the public grid cannot hook them up quickly enough.
Such workarounds signal broader concerns. Business associations have noted that power instability is already impacting productivity in certain regions. Occasional electricity curtailments and unplanned outages have hit factories in northern Mexico, for instance, disrupting assembly lines and supply chains. If the grid’s reliability issues aren’t addressed, this could dampen Mexico’s appeal as an investment destination just as the country is trying to capitalize on global manufacturing shifts. For everyday residents too, a stressed grid could mean more inconvenient blackouts, especially during peak usage periods.
Plans to Rebuild — Will It Be Enough?
Mexico’s government and CFE are not ignoring the problem. The new presidential administration has rolled out a multi-year Plan de Fortalecimiento y Expansión (Strengthening and Expansion Plan) for 2025–2030 to upgrade the electricity system. Under this plan, the country aims to invest around $8.2 billion to reinforce the power grid nationwide. That includes building 275 new transmission lines and over 500 new or expanded substations to increase coverage and capacity across the states. CFE has also begun seeking partnerships with private energy developers and inviting bids for new generation projects—particularly in renewables such as solar and wind—to boost supply. These measures mark a departure from the past six years, during which very few large-scale grid expansions or power plant additions were initiated.
However, energy experts caution that these efforts, while significant, may only scratch the surface of what’s needed. The planned transmission upgrades would expand Mexico’s network by only a small fraction (roughly 6% more lines than exist today) after more than a decade of stagnation. In other words, even if all the announced projects are completed, the grid would still be only marginally less constrained than before. And many of those projects are long-term — the major new power plants and lines are not expected to come online until 2027 or later. That leaves a tight window to shore up reliability in the interim. “Regulatory fixes are underway, but implementation has been slow, and time is short to reverse the lag,” observed another analyst, Víctor Ramírez of consulting firm P21Energía. He noted that while partnerships with the private sector could eventually increase energy supply, the immediate challenge causing blackouts is the lack of investment in critical transmission and distribution infrastructure. In short, the fixes are coming, but not fast enough to erase the current vulnerability.
Financial Hurdles for CFE
Complicating the situation is the financial strain on CFE itself. The utility’s operational and fiscal health has been under pressure in recent years, which in part explains the pullback in spending. By the end of 2025, CFE’s debts and unpaid obligations to suppliers had climbed to record highs, putting the company in a tighter budgetary position. The federal government subsidizes CFE heavily — covering costs to keep residential electricity tariffs low, among other things — but those subsidies also reflect that the company isn’t generating enough revenue to fund all its investments internally.
Notably, CFE did report a profit of about 55 billion pesos (around $3 billion) for the first nine months of 2025, a surprising turnaround at first glance. However, energy economists point out that this paper’s profit was driven largely by currency exchange gains due to a strong peso, rather than by improved efficiency or higher electricity sales. In reality, CFE’s core power business remains a low-margin operation once you strip out government support and accounting effects. The firm is still contending with hefty legacy costs, including expensive contracts and projects that aren’t yet productive (for example, payments of $50 million a month for a major gas pipeline that’s not fully in use). These financial headwinds mean CFE has limited flexibility to ramp up infrastructure spending on its own, unless additional government funding or private investment steps in. It’s a delicate balancing act: the utility needs to invest more to improve reliability, but it must also mind its debt and avoid putting further strain on public finances.
A Cautionary Outlook
For Mexico’s millions of electricity users — from homeowners in Mérida to factory owners in Monterrey — the trajectory of CFE’s investment is a matter of real consequence. The 24% drop in spending in 2025 has rung alarm bells about the future. The big question now is whether this trend can be quickly reversed before it undermines the country’s economic momentum. If power demand continues to climb as expected and grid upgrades lag, Mexico could face an era of more frequent power interruptions and capacity bottlenecks. These would not only disrupt daily life but also impose economic costs, ranging from lost productivity to stunted industrial growth.
The next couple of years will be critical. The government’s new plans and partnerships need to translate into shovels in the ground sooner rather than later. CFE will have to navigate its financial constraints carefully to deliver on promised projects. Meanwhile, businesses and citizens will hope that last year’s blackouts were a warning—one that spurs action to reinforce the system. The stakes are high: a robust power grid is the backbone of any modern economy. Mexico’s ability to ensure reliable electricity amid rising demand will play a key role in its continued growth. For now, analysts urge a sense of urgency. The recent investment plunge may be reversible, but the longer the grid’s expansion remains slow, the greater the risk that the lights will flicker more often across the nation.
