Isolux wins Peruvian power transmission concession

Proinversión, Peru’s private investment promotion agency, has awarded to a consortium led by Isolux the Moyobamba-Iquitos power transmission concession.

Isolux by offering a total investment of US$499 million and an equivalent service cost of US$74.6 million beat out competition from Abengoa which offered a total investment of US$579 million and an equivalent service cost of US$86.7 million.

The project comprises the concession to design, finance, build, operate, and maintain a transmission line and associated substations for a period of 30 years plus the construction period (52 months).

The line concession, with an approximate length of 600 km and a rated capacity of 145 MVA, will enable the Iquitos Isolated Electrical System to be connected to Peru's national grid, the National Interconnected Electrical System (SEIN).

The project includes the construction of a 220 kV transmission line and supplementary facilities from the 220 kV busbars in the Moyobamba Nueva Substation, to a completely new substation close to the existing Iquitos Substation, hereinafter called Iquitos Nueva Substation. An additional substation will also be built on the transmission line path, called Intermediate Substation.

This project also includes serial and parallel reactive compensation systems, to be installed in the Moyobamba Nueva, Intermediate and Iquitos Nueva Substations, as well as the 60 kV connection between the Iquitos Nueva and Iquitos Substations. The scope of the project also includes provisions in space and facilities for the implementation of future expansions of these substations, for both 220 kV and 60 kV.
