Ecuador Completes Nationwide Electrical Maintenance to Bolster Transmission System and Energy Security

The Corporación Eléctrica del Ecuador (Celec EP) announced on October 17, 2026, the successful conclusion of programmed interventions in the country's transmission substations. These operations, carried out between 03:00 and 06:00, were coordinated with the Ministry of Environment and Energy and the National Electricity Operator (Cenace). The primary objective was to strengthen the National Transmission System (SNT) and ensure energy security across Ecuadorian territory.

Parallel maintenance work was conducted by the Corporación Nacional de Electricidad (CNEL EP) on urban distribution infrastructure, including the Puerto Santa Ana substation in Guayaquil. In the province of Los Ríos, specifically at the Nueva Babahoyo Substation, a mobile MVA substation was installed under the supervision of Transelectric manager Olga Espinoza, intended to reinforce the provincial electrical system. Additionally, in Guayas province, a structural replacement was executed on the derivation towards the Ciudad Celeste substation in Samborondón.

The state plan encompassed a total of 54 contingency interventions across fifteen provinces. This included 47 tasks at the level of distribution companies and seven on key transmission system infrastructures. Strategic facilities addressed included substations in Ambato (Tungurahua), Jivino (Sucumbíos), Quevedo and Nueva Babahoyo (Los Ríos), and San Gregorio (Manabí). The comprehensive operation covered provinces such as Guayas, Los Ríos, Manabí, El Oro, Azuay, Esmeraldas, Chimborazo, Sucumbíos, Pichincha, Cotopaxi, Tungurahua, Napo, Morona Santiago, Zamora Chinchipe, and Loja.

These maintenance efforts align with a preventive plan announced by President Daniel Noboa, designed to prepare for the months anticipated to be most affected by the El Niño phenomenon. The Ministry of Environment and Energy confirmed the conclusion of these preventive maintenance works in the transmission and distribution systems of 15 provinces. This follows a period of scheduled power suspensions for high and medium voltage clients since October 12, and an announcement on October 16 that Colombia would resume energy supply to Ecuador, which had been at zero since September 7 due to hydrological conditions.

What to watch

The successful completion of these widespread maintenance operations indicates a proactive approach to mitigating potential energy supply issues, particularly in anticipation of El Niño's impact. The installation of new infrastructure, such as the mobile MVA substation in Los Ríos, suggests targeted improvements to regional grid stability. Monitoring the actual impact of these interventions on grid reliability and the frequency of power outages in the coming months will be key to assessing their effectiveness. The resumption of energy supply from Colombia also provides an immediate buffer, but the long-term stability will depend on the domestic infrastructure's resilience.
