According to data from the operator E-Redes, temporary electricity supply interruptions are scheduled for this coming Sunday in zones across multiple Portuguese municipalities, including Leiria, Montemor-o-Novo, Portimão, Barreiro, Loulé, Odemira, and Covilhã, as well as additional areas such as Lisboa, Oeiras, Sintra, Tomar, Lagos, Olhão, and Faro. These planned outages are designed to allow technical teams to safely perform maintenance, conservation, repair, or infrastructure reinforcement work on the distribution network.
Scheduled Grid Maintenance Across Multiple Municipalities
The planned interventions will primarily take place during the morning hours. According to E-Redes, most affected zones will experience outages between 07h00 and 11h00, though the Covilhã intervention features a shorter window from 09h00 to 10h30. Outages in municipalities like Lisboa, Oeiras, Sintra, Tomar, Lagos, Olhão, and Faro are scheduled across varying morning blocks, starting as early as 05h00 in Lisboa and running through 11h00.
Operators emphasize that including a municipality or parish on the maintenance list does not mean the entire area will lose power. E-Redes clarifies that the interruptions are localized to specific postal codes, potentially impacting only a single street, part of a street, or a small group of buildings. For instance, Leiria features multiple postal codes across the União das Freguesias de Marrazes e Barosa and Leiria, Pousos, Barreira e Cortes, while specific streets in Lisboa’s Campolide parish—such as Avenida Conselheiro Fernando de Sousa and Rua Professor Sousa da Câmara—will face supply cuts.
Operational Context and Safety Rationale
These temporary interruptions do not stem from unexpected faults or sudden breakdowns. According to E-Redes, the planned outages are scheduled ahead of time to let technical crews work on electrical infrastructure under secure conditions, aiming to “corrigir situações que podem gerar insegurança da rede elétrica e/ou prevenção de avarias” and “garantir a qualidade do serviço.”
Did You Know? E-Redes notes that this type of scheduled maintenance intervention affects, on average, cerca de 2.000 dos aproximadamente 6,5 milhões de clientes servidos pela empresa em cada semana.
The operator limits both the duration and the customer footprint of each intervention, utilizing service cuts only when infrastructure work cannot proceed while maintaining active electrical flow.
How Residents Can Confirm Outage Status
Residents seeking to verify if a specific address falls within the maintenance zones can consult the scheduled work map provided on the E-Redes Open Data Portal. The portal details information down to the complete seven-digit postal code, allowing individuals to pinpoint disruptions at a granular level rather than relying on broader municipal or parish boundaries.
In addition to portal checks, customers potentially affected may receive advance notifications directly from E-Redes via SMS or email, provided their contact details are current within their account contracts. Reviewing these specific postal codes remains the most precise method to determine whether a particular street or building will experience a temporary supply pause.
