Three queues formed at the same time
For most of the last decade, the hard part of an industrial project was money and permits. In 2026 the hard part is delivery slots. Three separate queues — generation equipment, electrical apparatus, and grid interconnection — tightened simultaneously, and they now compound instead of overlapping.
Queue one: generation equipment is sold forward, not sold out
GE Vernova's gas equipment backlog and slot reservations moved from 100 GW to 116 GW in a single quarter (Q2 2026), with management guiding to at least 125 GW by year end. The company is taking reservations for 2031 deliveries today; booking-to-delivery on large frame units runs four to five years, against two to three years earlier this decade. Manufacturing capacity is being expanded — roughly 20 GW per year now, targeting 30 GW by 2030 — but that expansion lands after the projects being planned this year.
Queue two: the electrical apparatus behind the meter
The bottleneck is not only turbines. The ordinary equipment that converts an interconnection into usable kVAs on a plant floor has repriced in time:
| Equipment | Lead time (2026) | Practical read |
|---|---|---|
| Medium-voltage switchgear, 15 kV | 52–80 weeks | Order before groundbreaking, not after |
| Pad-mount transformers | 40–65 weeks | Often the last item anyone schedules |
| Substation transformers, 5–50 MVA | 75–110 weeks | Two years of calendar for one asset |
| Generator step-up, >50 MVA | 100–150+ weeks | Sets the date for any on-site generation |
| Large diesel gensets, >3,000 kW | 90–110 weeks | Backup is no longer a late add-on |
The operating rule circulating among developers is blunt: if the electrical equipment is not ordered 12 to 18 months before site mobilization, the schedule is already late. Switchgear and transformer orders should precede groundbreaking by six to twelve months.
Queue three: the interconnection itself
On the Mexican side, demand is the variable that is not slowing down. IMCO projects electricity consumption growing an average of 4.5% per year between 2026 and 2030, and estimates roughly 11.9 GW of additional generation capacity needed by 2030 beyond current projections. The public response is real and sizeable — the 2025–2030 Strengthening and Expansion Plan commits about US$22 billion across generation, transmission and distribution, with US$8.177 billion earmarked for the national transmission network: 275 new lines and 524 substation works.
But plans are not energized assets. Distributed generation in Mexico closed 2025 at roughly 5 to 5.5 GW, and industry operators note that some of the interconnection paperwork needed to move new projects — the formats themselves — is still pending issuance. For a company deciding where to put a plant, the useful question is not how large the national program is. It is whether the node in front of the site has capacity inside the project's own window.
A national plan reduces medium-term risk. It does not move a start-up date that is already on a customer's calendar.
M2 Energy · capacity practiceWhat a kVA actually measures — and why the unit matters now
A kilowatt (kW) is the power a plant consumes. A kilovolt-ampere (kVA) is the power the electrical system must be built to carry. The two are not the same number: motors, drives, welders and chillers draw reactive current that does no useful work but occupies capacity, so a facility with 800 kW of real load can easily require 1,000 kVA of installed capacity — or more, once inrush, harmonics and future lines are accounted for.
Every constrained item above is sold in kVA or MVA, not in kW: the transformer, the switchgear, the generator, the utility's allotment at the node. That is why kVAs are the honest unit for a project schedule.
A plant does not run out of kilowatts. It runs out of kVAs — at the transformer, at the node, or in the delivery calendar of the equipment that would have supplied them. Two industrial parks with identical labor, logistics and incentives can be eighteen months apart on energization, and nothing on the site tour reveals which is which.
Three sizing errors turn into schedule losses in this market. Sizing to nameplate load and ignoring power factor, which undersizes the transformer. Sizing to today's line-up with no headroom, which turns a phase-two expansion into a second interconnection request. And treating backup as a separate, later project, which in 2026 means a generator that arrives two years after the plant needs it.
The four clocks: what has to be started in parallel, not in sequence
Projects that hold their dates in this environment stopped running these steps one after another. All four clocks start at site selection.
Capacity at the node
Confirmed available capacity at the specific point of interconnection, in kVA, with the date it becomes available — not the regional average, not the national program.
The utility process
Load application, studies and the approval path, with the documentation that is actually being accepted today. Sequence matters more than paperwork volume.
Equipment procurement
Transformer, switchgear and protection ordered against the lead times above — which means specifying before final layout is frozen, on purpose.
The bridge
On-site generation, cogeneration or storage sized to cover the gap between the plant's start-up date and the date the grid can actually serve it.
The pattern we see repeatedly is a good project with a correct budget and an incorrect assumption: that capacity is a procurement item that can be handled once construction is underway. In 2026 capacity is a lead-time asset. It behaves like long-lead equipment, because that is exactly what it is.
The practical consequence is that a site decision made without a capacity read is a schedule decision made blind. Two industrial parks with identical labor, logistics and incentives can be eighteen months apart on energization — and nothing on the site tour reveals it.
M2 Energy works on that specific question. If you are evaluating a site, an expansion or a load increase in Mexico and want an orientation on what the numbers mean for your case — capacity at the node, the utility path, equipment exposure, and whether on-site generation is warranted as a bridge — that is the conversation we are set up to have. No cost for the initial assessment.
