Users who exceed the established limits may face higher tariffs or even be reclassified to the high-consumption tariff (DAC), which implies the loss of support. This mechanism seeks to balance access to energy with responsible use during periods of highest demand. Heat increases electricity spending. The activation of summer tariffs occurs in a context where electricity consumption becomes indispensable in much of the country, directly impacting household budgets. With this scheme, the federal government seeks to mitigate the increase in electricity bills; however, the benefit will depend on each user's consumption, which maintains the challenge of controlling energy spending during the high-temperature season. The Federal Electricity Commission (CFE) began the activation of summer tariffs for domestic users in various regions of the country, as part of a subsidy scheme that seeks to contain the economic impact of increased electricity consumption during the heat season. This measure is a response to the increase in energy demand caused by the intensive use of fans, cooling, and air conditioning in areas where temperatures exceed 30 degrees Celsius. Automatic subsidy in the electricity bill. The tariff adjustment consists of a reduction in the cost per kilowatt-hour, applied automatically in the electricity bill for households with domestic tariffs, without the need for additional procedures. This support is concentrated in warm climate regions and mainly benefits users under tariff schemes such as 1C, 1D, 1E, and 1F. Application by season and weather conditions. Implementation begins, in most states, on May 1st and extends for approximately six months. However, in entities with more extreme temperatures, such as Sonora, the subsidy can begin as early as April 1st. The application period is determined by the weather conditions of each region, which defines the time in which the support is necessary to cushion energy spending. High consumption can eliminate the benefit. Although the subsidy reduces the cost of the service, its application is conditional on the level of consumption.
