E-Redes (formerly EDP Distribuição) is the company that operates Portugal's low- and medium-voltage electricity distribution network, serving over 99% of mainland Portugal. It is a subsidiary of EDP (Energias de Portugal), the country's largest energy utility.

E-Redes is responsible for maintaining power lines, substations, and transformers; connecting new customers and solar panels to the grid; reading meters; and restoring power after outages. It operates under a concession granted by the Portuguese government and is regulated by ERSE (Entidade Reguladora dos Serviços Energéticos).

During storms and extreme weather, E-Redes coordinates emergency repair crews to restore electricity supply. Residents can report outages and check restoration timelines through the E-Redes website or app. The company is also central to Portugal's energy transition, managing the integration of growing rooftop solar and electric vehicle charging into the distribution grid.
