Iberdrola Ingenieria y Construccion, a subsidiary of Iberdrola, has announced that it has been awarded a $16.3 million contract to build a substation and a 10.9km underground transmission line in the Mexican state of Sonora.

The turnkey project, awarded by the Mexican Federal Electricity Commission (CFE), is scheduled for completion within a year.

According to the company, the voltage of the underground line awarded by CFE is 115kV and the 115/13.8kV associated substation has a capacity of 30MVA. The site will have two high-voltage feeders, six medium-voltage feeders and 5.7km of trunk lines.

It said that the company has already built around 40 electricity substations in the country with an installed capacity of some 2,000 mega volt amperes (MVA) and transformation capacity of 400, 230 and 115 kilovolts (kV), as well as over 50 transmission lines covering over 1,615 km.

Furthermore, the Monterrrey Technological substation having 19 115 kV and eight 400 kV bays, make it one of the largest SF6-encapsulated facilities of its kind in Latin America, claims the company.
