The Corporación Eléctrica del Ecuador (CELEC EP) announced on March 24 that it has started moving a 224 megavolt-ampere (MVA) autotransformer from the Pascuales substation in Guayaquil to the Santa Elena substation. The company said this equipment will double electricity transmission capacity and bring long-term benefits for residents.
This operation involves specialized logistics because the autotransformer weighs more than 100 tons. Special vehicles with multiple axles are being used to distribute the load, and technical route studies have been conducted to ensure bridge and road safety. CELEC also coordinated with other institutions to secure necessary permits, while strict protocols are in place during transport to prevent vibrations or movements that could damage sensitive internal components.
At the Santa Elena substation, hydraulic cranes will be used for precise placement of the equipment. Technical tests and assembly of electromechanical parts will follow, all handled by specialized personnel.
To address immediate needs while this process is underway, CELEC has taken several emergency measures. These include adding 33 megawatts (MW) through activation of Central Térmica Santa Elena III, arranging private backup generation, and coordinating with CENACE—the national electricity operator—to optimize system operations. On March 16, a new transformer at Central Térmica Santa Elena II was put into service, adding another 7 MW locally.
Additional energy supplies have been incorporated: so far, there are increases of 3 MW from Chanduy substation and 12 MW from Pechiche. Work continues on integrating another 6 MW from La Libertad. According to CELEC EP’s statement, these actions aim to fully meet electricity demand in Santa Elena province.
The government reiterated its commitment “to work technically and jointly” so that residents receive stable and continuous electrical service.
