The Corporación Eléctrica del Ecuador (CELEC EP) began transporting a 224 megavolt-ampere (MVA) autotransformer from the Pascuales substation in Guayaquil to the Santa Elena substation on March 24. The company said this equipment will double the electric transmission capacity and bring long-term benefits for residents.
The move is considered highly specialized because the transformer weighs more than 100 tons, requiring careful logistical planning. Special transport vehicles are being used to distribute the load across multiple axles, and technical route studies have been conducted to ensure bridges and roads can safely support the weight. CELEC EP also coordinated with other institutions to secure necessary permits and is following strict protocols during transport to prevent vibrations or movements that could damage sensitive internal components.
At the Santa Elena substation, installation will involve precise maneuvers using high-capacity hydraulic cranes to position the equipment. Technical tests and assembly of electromechanical parts will be carried out by specialized staff to ensure proper operation.
To address immediate needs, CELEC EP has already taken several emergency measures. These include adding 33 megawatts (MW) through activation of Central Térmica Santa Elena III, securing private backup generation, and coordinating with CENACE—the national electricity operator—to optimize system operations. On March 16, a new 10 MVA transformer was put into service at Central Térmica Santa Elena II, adding another 7 MW for provincial use.
Additional energy has been progressively incorporated: as of now, there are increases of 3 MW from Chanduy substation and 12 MW from Pechiche, with work ongoing to add another 6 MW from La Libertad. With these actions combined, authorities expect that all electricity demand in Santa Elena province will soon be met.
“The National Government reaffirms its commitment to work technically and collaboratively so that stable, safe and continuous electric service is guaranteed for all citizens of Santa Elena province,” said officials.
