How much does electricity cost in Mérida in 2026? How CFE's subsidy tiers work, what the DAC surcharge is, typical monthly bills with and without AC, and how to manage costs in Mexico's heat.
Electricity and AC Costs in Mérida: What to Actually Expect
Your first CFE bill in Mérida might be a pleasant surprise — or a shock — depending on how you use air conditioning. Understanding how Mexico’s electricity pricing works in advance will help you manage what is typically the largest monthly utility expense for expats in Yucatán.
How CFE Billing Works in Mexico
CFE (Comisión Federal de Electricidad) is Mexico’s national electricity utility, which operates as a near-monopoly for residential service. CFE uses a heavily subsidized tiered pricing system that rewards low consumption and penalizes high consumption — particularly relevant for Mérida expats who run AC heavily in summer.
The Billing Cycle
CFE bills bimonthly (every 2 months), not monthly. Your bill covers 60 days of consumption. This is different from what most North Americans and Europeans are used to — two months of summer AC consumption in one bill can look alarming.
The Subsidy Tiers (Tarifas)
Most residential customers in Mérida are on Tarifa 1E — the tropical/hot zone residential rate, which has the most generous subsidized baseline:
| Tarifa | Zone | Who qualifies |
|---|---|---|
| 1 | Temperate | CDMX, Guadalajara, highland areas |
| 1A | Warm | Much of coastal Mexico |
| 1B | Hot | Many northern cities |
| 1C | Very hot | High heat areas |
| 1E | Tropical | Mérida, Yucatán, parts of Gulf coast |
| 1F | Desert/extreme | Sonora, parts of Baja |
Tarifa 1E has the highest baseline consumption before penalties kick in. This is Mexico’s recognition that you basically need AC to survive a Yucatán summer.
The Consumption Tiers Within Tarifa 1E
Within 1E, consumption is priced in three tiers (approximate 2026 rates per kWh, per 2-month billing period):
| Tier | Consumption Range (bimonthly) | Rate/kWh (approx.) |
|---|---|---|
| Básico | First ~1,000 kWh | $0.80–$1.20 MXN/kWh |
| Intermedio | Next ~2,000 kWh | $1.00–$1.50 MXN/kWh |
| Excedente | Above that | $3.50–$5.00 MXN/kWh |
Exact thresholds and rates update quarterly with SHCP approval. These are approximate 2026 figures.
The first ~1,000 kWh bimonthly are extremely cheap. Consumption over ~3,000 kWh bimonthly starts to cost meaningfully more.
The DAC Surcharge: The Bill That Shocks Expats
DAC (Doméstica de Alto Consumo) is a special high-consumption penalty tariff. If your consumption exceeds the Tarifa 1E thresholds by a significant margin for 6 or more consecutive billing periods, CFE reclassifies you as a DAC customer.
What DAC means:
- Your entire consumption is billed at unsubsidized market rates — roughly 3–5× the subsidized tier rates
- A bill that was $800 MXN bimonthly can become $3,000–$5,000 MXN bimonthly
- Once classified DAC, you stay in DAC for 12 months minimum even if your consumption drops
How to avoid DAC:
- Monitor your kWh consumption before hitting the threshold
- Use AC strategically — programmable thermostats, shutting off rooms not in use
- Adjust AC temperature (26–27°C instead of 20°C makes a significant consumption difference)
- Use ceiling fans to extend AC efficiency
- Some homeowners install sub-meters or monitors (Emporia, Sense) to track real-time consumption
If you’re already in DAC: You can apply to exit after demonstrating consistently lower consumption for 12 billing periods. The process involves a visit to the CFE office.
Typical Monthly AC Bills in Mérida (2026 Estimates)
These are rough ranges based on typical residential situations — actual bills depend on home size, insulation, number of AC units, and usage patterns.
| Situation | Bimonthly bill (approx.) | Monthly equivalent |
|---|---|---|
| Small apartment, 1 AC unit, used moderately | $600–$1,400 MXN | $300–$700 MXN |
| House 150–200 m², 2–3 AC units, moderate use | $1,200–$2,800 MXN | $600–$1,400 MXN |
| House 200–350 m², 3–5 AC units, heavy use (summer) | $2,500–$5,000 MXN | $1,250–$2,500 MXN |
| Large house/poor insulation, AC all day year-round | $5,000–$10,000+ MXN | $2,500–$5,000+ MXN |
Seasonal variation is significant:
- May–October (hot/rainy season): Bills are 2–4× higher than winter months. A house that costs $800 MXN bimonthly in December may cost $3,000+ in July.
- November–April (winter/dry): Pleasant nights mean less overnight AC use; bills drop substantially.
Practical AC Management for Mérida Homes
What works best in Mérida’s climate:
- Mini-split units are standard and efficient. Inverter-type mini-splits (look for the “inverter” label) adjust their output dynamically and use significantly less electricity than on/off systems at equivalent cooling.
- Inverter vs. non-inverter: Inverter mini-splits cost 20–40% more to purchase but can use 30–50% less electricity. Worth it for primary AC units.
- Ceiling fans: Running a ceiling fan allows you to set the AC thermostat 2–3°C higher and maintain the same comfort. Fans use 30–70 watts vs. 1,000–2,500 watts for an AC unit.
- 26°C thermostat setting: Most Mexicans and adapted expats find 26–27°C comfortable with a ceiling fan. Setting to 22°C dramatically increases consumption.
- Nighttime strategy: In the dry season (Nov–Mar), Mérida nights cool to 18–22°C — fans-only sleeping is comfortable and saves significant electricity.
Other Utilities: Quick Reference
| Utility | Provider | Typical Monthly Cost |
|---|---|---|
| Electricity | CFE | $300–$2,500 MXN (varies enormously by AC use) |
| Water | JAPAM (Municipio de Mérida) | $100–$250 MXN/month |
| Natural gas (if piped) | Gas Natural Fenosa / cylinders | $150–$400 MXN/month |
| Internet (100 Mbps fiber) | Telmex/Megacable/Izzi | $350–$550 MXN/month |
| Drinking water (garrafones) | Various | $100–$200 MXN/month (2–4 jugs) |
Water: Mérida’s tap water is not safe to drink directly. Municipal water is used for bathing, laundry, and dishes. Drinking water comes from 20-liter garrafones ($25–$45 MXN each) or a reverse-osmosis filter system.
How to Pay Your CFE Bill
