CFE’s DAC rate—its official Mexican tariff code, derived from the Spanish Tarifa Doméstica de Alto Consumo—applies to households whose average monthly electricity use exceeds the limit established for their locality. Once a home is placed on this rate, it loses the government subsidy entirely, which can make the bill up to four times more expensive.
How can you leave CFE’s DAC rate?
To leave CFE’s DAC rate, you must reduce your electricity use. CFE evaluates your average consumption over the previous 12 months. Once that monthly average falls below the limit established for your locality, your service will automatically return to a subsidized residential rate.
Install solar panels
If your energy needs exceed what you can reasonably reduce by changing your consumption habits, installing a solar-panel system is the most effective alternative for leaving the DAC rate. By generating your own electricity, you can drastically reduce the amount of energy you buy from the grid, lower your annual average, and leave the high-consumption bracket on a lasting basis.
