A pair of Colombian firms have been granted a 30-year concession to build and operate a 220-kilovolt electrical transmission line in Peru that will draw power from a hydroelectric plant near Machu Picchu. Empresa de Energia de Bogota S.A. and Interconexion Electrica S.A. will build the 204-kilometer Machu Picchu-Abancay-Cotaruse line for $62.5 million, officials said. Over the summer, the Zürich, Switzerland-based ABB group was awarded a three-year, $148.5-million contract to increase the installed power of the Machu Picchu facility to 99.86 megawatts and build an 87.57-MW facility near Santa Teresa. The project is designed to regulate the level and flow of the Vilcanota River, minimizing the risk of landslides and flooding.
