Mexico’s residential “average” splinters the moment you compare Mérida’s humid heat with CDMX’s milder nights. Domestic customers sit in tariff zones (1 through 1F) that reflect expected cooling stress; crossing into DAC (high domestic consumption) on a rolling basis can change effective MXN/kWh sharply. That is why single-number SEO tables fail: your zone, your rolling average, and your bill line items define reality.
Illustrative bands: City apartments often land roughly 150–450 kWh/month; large homes with pools and multiple mini-splits can exceed 500–1,300+ kWh/month in hot seasons—especially near DAC thresholds.

CFE zones, DAC, and why averages need memory
DAC is not about one bad weekend—it is about consumption trends relative to your zone limit. CFE publishes domestic tariff tables; policy context also touches CRE for competitive market segments. Always verify current MXN/kWh and subsidy logic on CFE or your supplier portal.
Illustrative monthly kWh bands
| Profile | Typical kWh/month (illustrative) |
|---|---|
| Small apartment, selective AC | 120–320 |
| Mid-size home, regular mini-splits | 320–700 |
| Large home, pool pump, heavy cooling | 700–1,400+ |
Watch for: second freezers, resistive hot water, home workshops, and extended family under one meter.
Coastal humidity versus altiplano nights
Coastal homes fight latent load (dehumidification + cooling). Highland cities may lean more on resistance heating in cold snaps. The tariff zone on your contract reflects expected stress—not your taste in thermostat numbers.
What one-number articles miss
- DAC and subsidy mechanics.
- Pump and pool runtime in borderline zones.
- Second-home occupancy that averages strangely across months.
Worked example (illustration only)
520 kWh at MXN 1.35/kWh illustrative variable rate:
520 × 1.35 = MXN 702 before distribution lines, taxes, and fixed items.
If you trim 62 kWh (12%) through pump scheduling and AC maintenance → 458 kWh → 458 × 1.35 ≈ MXN 618 at the same illustrative rate.
FAQs
Where is the official DAC reference?
CFE publishes domestic tariff materials including DAC context—start from CFE customer tariff pages.
Why is my friend’s “average kWh” useless for me?
Different zone, floor area, occupancy, and DAC status change both kWh and effective price.
Do solar panels change typical grid kWh?
Imports can fall while gross consumption stays high—model netting/metering with your tariff class and installer.
Are mini-splits always efficient?
Only when sized, maintained, and shaded—a sun-cooked outdoor coil wastes kWh at any brand name.
How should I compare summer to summer?
Use kWh per day for the same calendar month and note guests or construction loads.
What if another supplier—not CFE—bills me?
Compare their published rate sheet; subsidy rules may differ from classic CFE domestic tables.
