An Iberdrola Ingenieria y Construccion-led consortium, including Elecnor, has completed a project for fortifying the electrical power grid in the northern Mexican states of Chihuahua and Sonora, which entailed the building and commissioning of five new 230kV and 115kV substations and 209km of power lines.

The $78.6 million contract was awarded to Iberdrola Ingenieria y Construccion (Iberinco) by Mexico’s Federal Electricity Commission (CFE) in open international bidding, in which the Spanish firm competed against Techint, Siemens and Areva T&D-Isolux.

Construction work began in October 2006, with the CFE taking provisional delivery of the new power transmission infrastructure 13 months later. Iberinco noted that the project has been completed ahead of schedule.

Iberinco has won several contracts to strengthen Mexico’s power grid, worth a total of some $500 million, to reportedly become the CFE’s main contractor in the power distribution area.
