Two near-identical plants break ground the same week. Eighteen months later one is running; the other is finished but dark, waiting on a transformer. The difference was rarely construction — it was the grid.
The line item nobody watches
Foreign investors track what they can see: tons of steel, square meters poured. But the longest-lead item on most industrial projects in Mexico is the electrical interconnection with CFE (Comisión Federal de Electricidad) — capacity confirmation, load studies, substation and energization. Unlike a wall, you can't add a shift to make it go faster.
Why smart teams still miss it
It is invisible on a schedule drawn from home-country experience, where grid power is a near-given. By the time a team realizes the building will be ready months before the power is, the months are gone.
Manage it from day one
- Verify real power capacity before committing to a site
- Start the CFE process in parallel with engineering, not after permits
- Engineer the electrical scope (substation, medium voltage, backup) as its own critical-path workstream
- Treat energization as a milestone with the weight of structural completion
Permits run in parallel, too
NOM, IMSS, STPS, SEMARNAT and Protección Civil all have their own timelines. An experienced local team sequences them alongside design so approvals don't stall the build.
One team owns the whole critical path
CTECP runs the grid, the permits and the building as one schedule. As a design-build / EPC contractor with 250+ projects across Mexico and in-house CFE and permitting experience, we find the real critical path early — and protect it.
