Colombia names ISA to interconnect 660-MW Porce 3

The government of Colombia has named Interconexion Electrica S.A. (ISA) to develop a substation and transmission line to interconnect the 660-MW Porce 3 hydroelectric project with Colombia’s national grid.

The Unidad de Planeacion Minero Energetica (UPME) of the Ministerio de Minas y Energia named ISA for design, procurement, construction, operation, and maintenance for 25 years of the 500-kilovolt Porce substation and two 22-kilometer, 500-kV power lines needed to connect with the grid. The project is to be commissioned by July 2010.

ISA said it was chosen from bidders including Empresa de Energia de Bogota, Empresas Publicas de Medellin, and INABENSA, an affiliate of international power group Abengoa. (HNN 10/11/07)

With an investment of US$920 million, Porce 3 is to be completed in 2011 in Antioquia Province.
