  • Ecuador's Corporación Eléctrica (Celec EP) will conduct preventive maintenance on Unit 2 of the Mazar Hydroelectric Plant starting July 14, 2026.
  • The maintenance, scheduled until July 29, is expected to ensure the reliability and efficiency of the Paute Integral Hydroelectric Complex.
  • National energy supply is guaranteed, with remaining units and backup power sources supporting generation during the maintenance period.

The Corporación Eléctrica del Ecuador (Celec EP) has announced that preventive maintenance will commence on Unit 2 of the Mazar Hydroelectric Plant at 10:00 PM on Tuesday, July 14, 2026. This essential technical intervention is scheduled to continue until July 29, 2026.

The maintenance is part of a routine technical schedule for Unit 2, which has a capacity of 85 MW, after reaching 8,000 hours of operation. Celec EP emphasizes that this procedure is crucial for guaranteeing the reliability, operational efficiency, and extending the lifespan of the generation equipment within the Paute Integral Hydroelectric Complex. Unit 2's power output represents approximately 4.8% of the complex's total installed capacity of 1,756 MW.

The supply of energy for the country is guaranteed during this period and no interruptions of the electrical service are foreseen.

Authorities have assured the public that the national energy supply will remain stable throughout this period. The country's electricity needs will be met by the continued operation of the remaining units at the Mazar plant and the support from other power stations integrated into the National Interconnected System. This ensures no service interruptions are anticipated for consumers.

Specialized technicians from Celec Sur Business Unit will carry out the maintenance. The scope of work includes critical activities such as comprehensive inspections and reviews of generation components, cleaning and calibration to optimize performance, and specific electromechanical maintenance on the turbine, generator, transformers, and auxiliary equipment of Unit 2. Celec EP conducts such planned maintenance regularly across its strategic facilities to ensure the consistent availability and reliability of Ecuador's electrical infrastructure.

This procedure is fundamental to ensure the reliability, operational efficiency, and prolong the useful life of the generation equipment of the Paute Integral Hydroelectric Complex.
