Parks built faster than the grid

Interconnection delays will stall new industrial parks through 2028

Institutional Intelligence Brief | Mexico Energy Partners | March 2026

Executive summary

  • AMPIP counts 103 industrial parks under construction across 17 states, needing 2,500 MW of additional capacity by 2030. On our reading of interconnection queue position and transmission loading in the northern and Bajío corridors, close to 70% of those parks will not be energized to full contracted load before 2028.
  • Modern manufacturing tenants draw 5 to 15 MW each, and a multi-tenant park 30 to 60 MW. That exceeds what the 115 kV distribution infrastructure serving several of these corridors can absorb without new works.
  • AMPIP puts the CFE transmission works phase at up to 25 months and the distribution phase at 6 months. End to end, from application to energization, the processes we have tracked since 2024 run 36 to 48 months in saturated regions.
  • For a tenant, the decision is contractual. Before signing a lease in a park that is not yet energized, demand an energization date warranty, a capacity allocation stated in kW per square meter, and liquidated damages if either fails.

Earliest programmed relief in these corridors

How the four figures above were produced. The denominator is the 103 parks under construction that AMPIP reported to Expansión on 28 November 2025. The 70% is a Mexico Energy Partners estimate, not a count of completed outcomes. We classified a park as at risk where its requested load exceeds the firm capacity we can identify at the nearest transformation point and no specific works contract was in place at the time of writing. The 48 month figure is measured, taken from interconnection processes we have followed since 2024, from application filing to energization. The 25 million dollar figure is the top of the 10 to 25 million dollar range we quote for substation and line works in US dollars of 2026, not an average. The 2028 date is read off the published works programs described below, not modeled.

The build-out and the load it needs

Mexico has roughly 500 industrial parks, of which AMPIP groups 457 covering 85 million square meters across 28 states. Another 103 parks are under construction, adding 21.5 million square meters across 17 states and 52 municipalities, with completion targeted by 2030. Diana Vázquez of AMPIP put the additional electricity requirement for those parks at 2,500 MW, against roughly 13 GW drawn by parks already operating. Expansión published those figures on 28 November 2025 and Industry & Energy Magazine repeated them on 3 January 2026.

The tenants driving that load are not the tenants the older parks were built for. Automotive and EV supply chains, electronics and semiconductor assembly, cold chain logistics, advanced materials, and data centers all draw more power per square meter than the general manufacturing the 115 kV networks in these corridors were sized around. A single multi-tenant park can reach 30 to 60 MW.

When a park of that size files for connection, the operator has to establish whether the network can carry the added load without breaching reliability criteria. Where lines and transformers are already close to their thermal limits, the answer is conditional. The load is approved against works: a new high-voltage substation, a line reinforcement, added transformation. Those works cost 10 to 25 million US dollars in our experience, in 2026 dollars, and a developer who did not budget for them meets that number after the land is bought.

Facility type Power requirement Grid impact Complexity Risk level
Automotive supplier plant 5 to 12 MW High Complex High
Electronics assembly 8 to 15 MW High Complex High
Cold storage logistics 6 to 10 MW Moderate Moderate Moderate
Plastics processing 4 to 8 MW Moderate Moderate Moderate
Hyperscale data center 80 to 120 MW Critical Extreme Critical
Basis: Mexico Energy Partners load ranges from tenant fit-out specifications, in MW of connected demand. Ranges move with automation level and shift pattern. The grid impact, complexity and risk columns are our ordinal ratings, not measurements. The data center row is included because those projects compete for the same transformation capacity.

Availability is a queue position, not a yes or no

Most developers treat electricity as binary. Either the grid reaches the site or it does not. The real constraint is the study and works sequence run by CENACE and CFE, and where your request sits in it.

Historically these parks connected at distribution level. At 30 to 60 MW that is no longer available, so a park now needs its own high-voltage substation, typically 115/34.5 kV or 230/34.5 kV, with high-voltage switchgear, protection and control, and a line interconnection. Ahead of energization comes the connection request, the system impact study, the engineering, and approval of any specific works. Each stage has a queue.

AMPIP told Expansión on 28 November 2025 that the CFE transmission works phase runs up to 25 months and the distribution phase about 6 months. Those are the works phases alone. On the processes Mexico Energy Partners has followed since 2024, the elapsed time from filing the connection request to energizing load in a saturated region runs 36 to 48 months. Studies, queue waiting and works approval all sit ahead of the 25 months AMPIP describes. The two figures are not in conflict. They measure different windows.

Data centers are bidding for the same capacity

Querétaro shows how fast a single sector can absorb headroom. Industry & Energy Magazine reported on 13 November 2025 that CloudHQ is committing 4.8 billion US dollars to six data centers on a 52 hectare campus requiring 900 MW, targeted for 2027. The same report said the state would need 900 MW of additional capacity to carry the wave of projects. It also described bottlenecks in the 115 kV network under projected 2028 load. Querétaro, the Valle de México and Monterrey are the three poles for this build-out, and they overlap almost exactly with the industrial park corridors.

An industrial park competing with that kind of data center power requirement is not competing on rent. It is competing for a place in the same queue, for the same transformation capacity, against a counterparty that can fund its own works.

Mexico Energy Partners estimates of the share of transformation capacity serving each corridor that is already committed at system peak, including approved but unenergized load. This is not a published regulatory measure. It does not separate line thermal loading from transformer capacity and it is not an N-1 result.

What the delay costs

Delay does not show up as a power bill. It shows up as rent not collected against debt already drawn. Twelve to twenty-four months of unenergized shell space on a leased-up park removes millions of dollars of income, and for a developer whose financing was underwritten to a lease-up schedule it can put covenants in play before it puts megawatts in the ground.

The tenant side is already visible. Industry & Energy Magazine reported on 15 October 2025 that AMPIP counted more than 80 installation or expansion projects stalled by electrical infrastructure deficits, with connection delays reaching 12 months in Yucatán and Coahuila. The same report put the cost of an hour without power at an advanced manufacturing plant above 100,000 pesos, before machinery damage or scrapped material. That is the arithmetic behind grid instability already affecting industrial operations.

Compliance costs sit on top. A park serving loads of this size has to meet the Código de Red, which usually means harmonic filters, reactive compensation and metering infrastructure, plus the maintenance those carry. Non-compliance can bring penalties or forced load reduction when the system is stressed.

Basis: Mexico Energy Partners estimates for a park of 30 to 60 MW requesting connection in a saturated northern or Bajío corridor in 2026. The probabilities are our judgment informed by the interconnection processes we followed from 2024 to 2026, not frequencies from a published register, and we have not disclosed the case count. Revenue impact assumes rent forgone on completed shell space at prevailing corridor rates in US dollars of 2026. Read the percentages as ranked likelihood rather than as measured odds.

What relief is programmed, and when

The federal answer exists and it is dated. SENER announced the Plan de Fortalecimiento y Expansión del Sistema Eléctrico Nacional 2025-2030 on 10 February 2025. It carries 22.377 billion US dollars of CFE investment, 22,674 MW of CFE generation and 6,400 MW from private projects. It also instructs CFE to build 145 transmission projects. Of those, 65 are programmed from 2025 to expand the national transmission network at 46.611 billion pesos, alongside 3.6 billion US dollars for distribution. Basham set out that breakdown in its note on the plan.

The sequencing matters more than the totals. Twenty-six of those projects are scheduled to conclude between 2025 and 2027, wind and solar arrive across 2027 to 2028, combined cycle plants across 2028 to 2029, and cogeneration and storage across 2029 to 2030. PRODESEN 2024-2038, published 31 May 2024, had already listed 194 CFE Transmisión projects covering 5,719 km-c of lines between 2024 and 2030.

Read against a park filing today, that is the reason 2028 is the earliest realistic relief date for the corridors in question. It is not a claim that nothing is being built. It is a statement about when built capacity reaches the specific transformation points these parks connect to.

What could make this read wrong

Three things would move it. If SENER's generation tender of 5,970 MW across six regions, reported by Industry & Energy Magazine on 13 November 2025 at an estimated 7.14 billion US dollars, lands close to the load centers rather than far from them, some corridors clear earlier than 2028. If the nearshoring pipeline slows and announced parks are deferred, the queue thins and everyone behind moves up. And if the Comisión Nacional de Energía reforms queue administration so that requests without committed capital lose position, real projects advance faster than this brief assumes.

The counter-case we do not accept is the one that says the parks will simply be connected on schedule. Nothing in the programmed works supports it for the saturated corridors.

What developers and tenants should do

Developers should file the connection request during land acquisition rather than after permitting. Queue position is the cheapest asset in this process and the only one that cannot be bought later. Financial models should carry a contingency for works and a fallback to onsite generation, and the interconnection assumption should be tested at the board rather than assumed.

Tenants have a different lever, and it is contractual. Before signing space in a park that is not yet energized, ask for an energization date warranty, a capacity allocation expressed in kW per square meter, and liquidated damages that survive a landlord's force majeure claim about the utility. A tenant with load above 1 MW also has the option of moving to qualified supply, which changes who sells the energy but not who builds the substation.

On the supply side, the layered options are the same for both parties. An early application secures position. A dedicated substation removes dependence on shared capacity. Onsite gas generation or solar plus storage at industrial sites covers load during the gap. A full microgrid removes the dependency altogether at the highest capital cost.

Mitigation strategy Capital required Timeline Risk reduction Payback period
Early interconnection application $100K to $250K Immediate 25% to 35% 6 to 12 months
Dedicated substation $10M to $25M 24 to 36 months 60% to 75% 36 to 48 months
Onsite natural gas generation $5M to $15M 12 to 18 months 40% to 55% 24 to 36 months
Solar and storage system $8M to $20M 12 to 24 months 35% to 50% 48 to 60 months
Full microgrid architecture $20M to $50M 24 to 48 months 80% to 95% 60 to 84 months
Basis: Mexico Energy Partners cost ranges for a park of 30 to 60 MW, in US dollars of 2026, covering equipment, works and commissioning. Risk reduction is our modeled cut in the probability of missing a target energization date, not a measured outcome. The payback column counts avoided delay cost only, against rent that would otherwise be forgone. It excludes any rent premium for guaranteed power, because we have no leasing data that evidences one.

Check your site's interconnection exposure before you close

Mexico Energy Partners returns the queue position and study status for the site, the nearest substations with capacity we can identify, and a cost range for the works the connection is likely to require. The review states what we measured and what we estimated, and it does not assert an energization date the operator has not given.

To start, send the site coordinates, the requested load in MW and the connection voltage, the target energization date, and any correspondence already exchanged on the interconnection request.
