Your CFE bill does not show a single price per kWh — it shows four consumption blocks, each priced differently. The letter on your tariff (1C, 1D, 1E, or 1F) determines exactly what you pay in each block and, critically, at what point your consumption triggers the DAC regime, where the price multiplies overnight.
Quick view
Complete guide to CFE domestic tariffs in BCS. Understand 1C–1F rate classes, May 2026 block prices, DAC cliff, and how solar ROI depends on which block you're buying from.
Apply to localities with a minimum summer temperature of 30–31 °C. The excess block reaches 3.992 MXN/kWh in summer, but the DAC threshold is lower (850–1,000 kWh/month), meaning a home with heavy AC use can cross the limit more easily.
Cover localities at 32–33 °C minimum. The básico block drops to 0.839 MXN/kWh, but the DAC threshold rises to 2,000–2,500 kWh/month. For a 1F home consuming 2,600 kWh/month, crossing that threshold means paying 7.249 MXN/kWh on every kWh.
The same solar panel has very different economic value depending on which block it displaces. Offsetting básico consumption (0.839 MXN/kWh) versus DAC consumption (7.249 MXN/kWh) produces an almost 9× difference in return.
Básico: 1.004 MXN/kWh · Lower intermediate: 1.163 MXN/kWh · Upper intermediate: 1.495 MXN/kWh · Excess: 3.992 MXN/kWh.
Real-world usage
This uses a 2,001 kWh bimonthly bill as a concrete example. The point is not to blame one appliance; it is to show how a Los Cabos home can become a high-consumption solar case.
A ~1.1 kW mini-split used 8 hours per day consumes about 528 kWh per bimonthly bill. Four units at that pattern can exceed the full example.
These bars mix daily use and per-cycle use. They help separate what drives a bill from what only adds a little.
Educational references only: older equipment, heat, real hours, pool size, insulation, and habits can move the result a lot. For a quote, the bill and property measurement lead.
Your domestic tariff
CFE assigns domestic climate tariffs based on the locality where your service address is registered. In BCS, the tariff class is determined by the average minimum summer temperature of your area. That letter changes both block prices and the DAC threshold. You do not choose your tariff — CFE assigns it based on where you live.

Block prices, summer 2026
Prices change between summer and winter seasons. Values below are for BCS summer 2026, as published by CFE. These are net energy prices excluding VAT.
Básico: 1.004 MXN/kWh · Lower intermediate: 1.163 MXN/kWh · Upper intermediate: 1.495 MXN/kWh · Excess: 3.992 MXN/kWh.
Básico: 0.839 MXN/kWh · Lower intermediate: 1.039 MXN/kWh · Upper intermediate 1E: 1.348 MXN/kWh · Upper intermediate 1F: 2.526 MXN/kWh · Excess: 3.992 MXN/kWh.
Once your 12-month rolling average crosses the threshold, all consumption shifts to 7.249 MXN/kWh flat plus a 145.24 MXN/month fixed charge. No more blocks. A household paying ~$4,000 MXN/month can see its bill jump to $16,000–$20,000 MXN/month if summer AC use pushes it into DAC.
The DAC cliff
The DAC tariff does not raise your marginal price — it replaces your entire pricing structure. The shift is not gradual: once you cross the 12-month rolling average threshold, CFE assigns DAC for the entire following billing period.
CFE averages your consumption over the last 12 bimonthly periods. If that average exceeds your tariff threshold (850, 1,000, 2,000, or 2,500 kWh/month), you enter DAC. The number appears on your bill under 'Consumo promedio mensual.'
If you are at 2,400 kWh/month in a 1F zone and the threshold is 2,500, reducing 150 kWh/month with solar does not just save on the most expensive blocks — it keeps your rolling average below the DAC limit. That protective effect is worth more than the simple per-kWh savings.
For a home already paying DAC rates, every solar kWh displaces consumption at 7.249 MXN/kWh. A well-oriented 8 kWp system in Los Cabos can produce 1,200–1,400 kWh/month — $8,700–$10,100 MXN/month in direct bill savings.
Solar in BCS
The return on a solar installation in Cabo does not depend primarily on panel brand or system size. It depends almost entirely on which tariff class you are on and which block you are buying from CFE.
A solar kWh displacing básico consumption (0.839 MXN/kWh) saves 0.84 MXN. The same kWh displacing DAC saves 7.249 MXN — 8.6× more.
Under CFE's Distributed Generation scheme, surplus energy you export is credited at the purchase rate, not wholesale. That favors sizing for maximum self-consumption rather than export.
Los Cabos has roughly 5.5–6 peak sun hours per day on average. The months of highest production (April–August) align almost perfectly with the highest AC consumption — maximizing self-consumption during the most expensive part of the year.
FAQ
Check your physical or digital bill. Near the top, next to your service number, you will see a field labeled 'Tarifa'. It will show '1C,' '1D,' '1E,' '1F,' or 'DAC.' CFE assigns it based on your registered service address — you cannot change it.
Yes. The tariff is tied to the service address locality, not the account holder. Moving within the municipality can change your class if the new address falls in a different climate zone.
CFE recalculates your 12-month rolling average at each billing period. If your average drops below your tariff threshold, you return to standard domestic rates. With a well-sized solar system, many customers in DAC manage to exit within 6–8 months.
No. The threshold varies by class: 850 kWh/month for 1C, 1,000 for 1D, 2,000 for 1E, and 2,500 for 1F. A large home in a 1F zone can consume twice as much as one in a 1C zone without triggering DAC.
Yes. CFE publishes summer rates (roughly May–October) and winter rates. Summer prices are higher across almost all blocks. The values on this page reflect the summer 2026 period.
For a home paying $12,000–$18,000 MXN/month in DAC, a well-sized system can reduce the bill to $1,500–$3,000 MXN/month, including the fixed charge and residual consumption the solar does not cover.
