Ecuador’s Drought Threatens 83% of Hydropower Capacity as Reservoirs Drop
Ecuador is warning of looming power shortages as drought linked to the 2026 El Niño threatens 33 hydroelectric plants that generate 83% of its electricity. Reservoirs are falling, and the country’s largest plant, Coca Codo Sinclair, is operating without key backup systems.
Ecuador is bracing for electricity shortages as a deepening drought undermines the dams that power most of the country, turning a climate‑driven water shortfall into an energy risk.
Officials warn that the 2026 El Niño weather pattern threatens 33 hydroelectric plants that together account for about 83% of national generating capacity. Recent assessments say reservoirs in key regions are operating below their maximum levels, with water dropping quickly as dry conditions persist. The Mazar reservoir, a critical part of Ecuador’s hydropower system, has reportedly lost 5.43 meters between August and September, shrinking the volume available for power generation and reducing the margin operators need to manage flows safely.
Particular concern centers on Coca Codo Sinclair, Ecuador’s largest power plant. The facility is reported to be operating without certain backup systems, increasing operational and safety risks at a time when it is expected to shoulder a heavier load. Hydroelectric plants depend on both robust mechanical systems and predictable water inputs; when either is compromised, grid operators may have to cut demand or risk damage to infrastructure.
For households and businesses, the threat translates into the possibility of blackouts, brownouts, and voltage fluctuations that can disrupt daily life and economic activity. In rural areas with limited backup options, power cuts can affect refrigeration, water pumping, and communications.
The situation highlights the downside of Ecuador’s heavy reliance on hydropower. In years with normal rainfall, dams provide relatively cheap, low‑emission electricity and reduce dependence on imported fuels. In drought years, they become a single point of failure, especially when more than four‑fifths of capacity is exposed to hydrological risk.
Signals to watch include any official announcements of power rationing, emergency fuel purchases for backup generation, or requests for electricity imports from neighboring countries. Public reactions to possible outages will indicate how much political pressure the government faces as it manages the crisis.
