Starting Monday, December 1, both Madrid and several locations in the community will experience scheduled power outages. Regarding this notice, we must be calm, since it is not a failure in the network or a massive breakdown, but rather temporary interruptions necessary to carry out maintenance work and improve electrical installations. The company i-DE, of the Iberdrola Group, explains in a press release that the cuts will affect the capital and 25 other Madrid municipalities between December 1 and 5, 2025.
Furthermore, in the press release published on its website, Iberdrola explains that if the work is completed before the scheduled time, the supply will be restored immediately and without prior notice.

In this sense, the safety recommendation that both homes and establishments must take into account is that they should not work on their electrical installations during the time the outage lasts, since the service could return sooner and cause serious accidents.
Which municipalities will be affected by the power outages?
In addition to Madrid capital, the scheduled blackouts will reach municipalities throughout the region. According to the statement, they will affect: Alcalá de Henares, Alcobendas, Alcorcón, Cercedilla, Cobeña, Collado Villalba, Colmenar del Arroyo, Colmenar Viejo, Cubas de la Sagra, El Escorial, Getafe, Hoyo de Manzanares, Las Rozas, Leganés, Los Molinos, Lozoyuela, Móstoles, Pelayos de la Presa, Pinto, Pozuelo de Alarcón, San Martín de Valdeiglesias, Torrejón de Ardoz, Torrelodones, Valdemoro and Villa del Prado.
The duration of the cuts will be variable. Although most of them will be done in the morning or afternoon, there are exceptions. For example, in Alcalá de Henares and Getafe there will also be night and early morning cuts.
