During the 90s, Mexico’s FEDERAL COMISSION OF ELECTRICITY (COMISION FEDERAL DE ELECTRICIDAD) began an ambitious expansion plan of Mexico’s Interconnected System of Extra High Voltage in 400 kV.

In order to fulfill the plan, FCE called for bidding which caused an intensive participation of the most important national and international companies in the market.

Due to the demanding requirement for qualified services, COINTEC started to provide services to Mexico in 1991, creating later on COINTEC S.A of C.V. an Engineering and Consulting Society under Mexican legislation.

From that moment, COINTEC participated on several projects presented by the FCE providing different engineering services from preliminary bidding projects to executive projects.

The following are some of the most important projects of Extra High Voltage Transmission Lines and their Transformer Stations:

 

  • EHVL 400 kV – ACATLAN – TESISTAN – AGUASCALIENTES (Bidding Project).
