Thinking about a solar investment in Mexico for your plant? This executive guide explains how industrial
grid-tied PV works with CFE, how it impacts PDBT, GDMTO and GDMTH tariffs, and the best
financing models (CAPEX, leasing, PPA) for foreign-managed factories. Built for decision-makers: clear, practical and local.
- Business impact: reduce daytime kWh, smooth kW demand, target high-cost time bands (GDMTH).
- Compliance: CFE interconnection, protection and safety requirements, proper documentation for audits and ESG/Scope 2.
- Where we work: San Luis Potosí Industrial Zone (WTC, Logistik, Colinas, Tres Naciones) and the Bajío corridor (GTO, QRO, AGS, JAL).

Mexico’s context for foreign plant leaders
Mexico offers excellent solar resource and a mature ecosystem of EPCs and component supply. Grid-tied PV connects to the
CFE distribution network under established interconnection and compensation schemes. In practice, your plant can generate
during the day, feed on-site loads first, and account for surplus/consumption via a bidirectional meter.
Note
Specific compensation rules, documentation and timelines depend on your tariff and location.
We handle the engineering package and interconnection submission end-to-end.
How industrial solar affects PDBT, GDMTO and GDMTH
PDBT (small demand, low voltage)
- Target daytime base load (HVAC, refrigeration, lighting, compressors).
- Result: lower kWh and operating cost with simple roof layouts.
GDMTO (medium voltage, no time-of-use)
- Reduce kWh and flatten peaks via sequencing/VFDs and PV coverage of base loads.
- Result: improved demand profile and steady savings.
GDMTH (medium voltage, time-of-use)
- Maximize production in intermediate/peak bands and reschedule processes when feasible.
- Result: strong reduction of hourly energy cost where tariffs are highest.
Investment models for foreign-managed sites
CAPEX (Direct Purchase / Loan)
- Pros: highest long-term IRR, full asset control, potential tax benefits.
- Cons: upfront capital or financing on balance sheet.
- See credit options and terms
Leasing (Financial/Operating)
- Pros: OPEX-style payments, option to purchase at term end (financial lease).
- Cons: higher total cost vs. direct CAPEX in many cases.
PPA (On-site Power Purchase Agreement)
- Pros: minimal CAPEX; pay per kWh; O&M included; cash-flow positive from month one in many cases.
- Cons: term commitment; asset is owned by the PPA provider.
Technical checklist for C&I (what really matters)
- Roofs & structures: load calculations, corrosion-resistant fixings, watertight penetrations (losa/lámina/teja).
- Shading & layout: chimneys, RTUs, parapets. Parking canopies are often ideal for added capacity.
- Electrical & safety: DC/AC disconnects, anti-islanding, grounding, surge protection, selectivity and coordination.
- Interconnection dossier: single-line diagrams, calculations, protective settings, labels and safety data.
- Monitoring & O&M: web/app portal, alarms, periodic cleaning, documented inspections for audits.
Operations & continuity
Standard grid-tied PV does not power the plant during outages due to anti-islanding. If you need
continuity, we integrate battery/UPS and control as a separate scope.
Dimensioning in minutes (order-of-magnitude)
Quick formula
Example: site uses 1.2 GWh/year; target 40% ⇒ 480 MWh/year.
With HSP=5 and PR=0.78 → kW ≈ 480,000 ÷ (5×365×0.78) ≈ ~337 kW
(≈600–650 modules at 550 Wp). We refine with roof surveys, shading and tariff bands.
ESG, reporting and brand value
- Scope 2 reductions: documented kWh generation helps corporate reporting (CDP, suppliers’ scorecards).
- Facility image: canopies and roof arrays support branding and customer/visitor tours.
- Documentation: commissioning files, monthly reports and safety records for audits.
Project timeline with Evoluo (C&I)
- Assessment: 12 utility bills, load profiles, roofs, as-built drawings and HSE constraints.
- Engineering: yield simulation, electrical single-lines, protection study, structural layout.
- Interconnection: submission to CFE Distribution and coordination for the bidirectional meter.
- Construction: HSE plan, installation, testing and commissioning.
- O&M: monitoring, cleaning, inspections, SLAs and performance reviews.
FAQ for foreign plant directors
- Can we phase the project? Yes. Many plants start with rooftops and add canopies or ground arrays later.
- Do we need batteries? Not for standard savings. Batteries are for backup or advanced peak control.
- What drives ROI? Tariff, daytime usage, roof area, shading, and chosen finance model (CAPEX vs OPEX).
- Will solar reduce outages? Not by itself. Add battery/UPS if you need ride-through.
