ALSTOM has won a Euro 51 million turnkey contract to supply six new substations and extend 12 others for the Mexican state utility Comision Federal de Electricidad (CFE) as part of a general upgrade of the Mexican power supply network.
ALSTOM's Transmission and Distribution Sector will undertake the engineering, supply, civil works, erection and commissioning for all the substations, which are situated all over the country. The company will build five new air-insulated switchgear (AIS) substations and, at Tanga Manga in the state of San Luis Potosi, a gas-insulated switchgear (GIS) substation. The 12 other substations will be extended with AIS bays.
The total transformation capacity of the substations will be 430 MVA, with 29.4 MVAR of power compensation. Thirteen of the substations, including the GIS substation, are to transform power from 115 to 13.8 kV, two are 138/13.8 kV substations and two are 115/23kV substations, with one 115-kV transmission substation.
The project, 504 Norte-Occidental, was financed under the Pideregas scheme, under which CFE offers large tenders for infrastructure work in the country. Equipment for the project includes disconnector switches, control panels, metal-clad and medium-voltage circuit breakers and instrument transformers, dead tank circuit breakers and live tank circuit breakers.
