Unexpected power cuts swept through Quito, Guayaquil, Ambato and other Ecuadorian cities on October 13-14, 2026, with no official explanation despite presidential assurances one week earlier that households would not face outages. The blackouts coincide with critically low water levels at the Mazar and Amaluza reservoirs, which feed hydroelectric plants supplying nearly one-fifth of national demand. With a deficit exceeding 1,000 megawatts and the dry season intensifying under El Niño conditions, further interruptions appear likely even as the government announces grid maintenance for October 17.
