The Comisión Federal de Electricidad's High-Consumption Domestic Rate (Tarifa DAC) posted a year-over-year increase of between 7.2% and 7.3% in October 2026, the largest for any October since 2022, according to El Financiero. The fixed monthly charge settled at 145.79 pesos across all regions, an annual rise of 3.1% versus the 141.42 pesos recorded in October 2025.
The adjustment lands squarely in the middle of Halloween decorating season, when many households add lights, projectors and animated figures. The DAC rate applies to homes whose average monthly consumption exceeds the threshold the CFE sets for their locality and that receive no government subsidy, so every kilowatt-hour is paid at full price. For the Mexican community in the United States and Canada, the figure carries double weight: many send money to cover utilities for the family home, and this is the bill that fluctuates most from one month to the next.
The price per kilowatt-hour varies by region. In October 2026 the DAC rate is quoted as follows:
- Baja California Sur: 7.131 pesos per kWh - Central region: 6.730 pesos - Baja California: 6.544 pesos - Northwest: 6.305 pesos - South and peninsula: 6.241 pesos - North and northeast: 6.142 pesos
This year's adjustment remains below that of October 2022, when the energy cost for this rate rose by roughly 30.4% year over year. In 2025 the increase was close to 6.7%. The CFE classifies a household under DAC based on a moving average of consumption, not on a single high bill, and reclassification to a subsidized rate happens automatically once average consumption falls below the zone's threshold.
The next bimonthly bill will be the first to reflect the combined effect of the rate hike and the extra consumption of the season. Checking the rate printed on the bill and the household's consumption history is the starting point for anticipating the amount.
