Alstom has been awarded two contracts, worth approximately 17 million euros, for the supply of seven power transformers to Sogamoso substation, located in the department of Santander (North Colombia), and for the construction of two 220-kV gas-insulated substations (GIS) in Armenia, located between Bogotá, Medellín and Cali; and in Alférez, in the region of Cali, department of Valle del Cauca. These projects will improve power quality and capacity as part of the expansion of Colombia's national grid.

The power transformers were awarded by Interconexión Eléctrica S.A. for Sogamoso substation. Alstom will supply seven 150-MVA power transformers to connect the power plant to the national grid. The project will be commissioned by the end of 2013.

The GIS substation contract was signed with Empresa de Energía de Bogotá. Alstom will design, supply, erect and commission 220-kV gas-insulated switchgear, including civil works. The project will be commissioned mid-2013.

Alstom's 220-kV gas-insulated switchgear is designed to avoid corrosion, offering a long service life. Its modular design saves space and also allows each of the compartments to be independently monitored. These features mean that it can be used for both indoor and outdoor applications, and allows for easy availability during repair and extension.
