Name of the Project
Songo–Matambo transmission line project.
Location
Cahora Bassa and Changara districts, Mozambique.
Project Owner/s
Electricidade de Moçambique (EDM).
Project Description
The project comprises the construction of a 118 km 400 kV high-voltage single-circuit transmission line from Songo to Matambo. The line is planned to pass through the site where the future Cataxa substation will be built to integrate the envisaged Mphanda Nkuwa hydropower plant. It will use self-supporting steel mesh overhead towers carrying a horizontal conductor configuration with an energy transport capacity of 2 300 MW.
The project includes the expansion of the Songo substation to extend the 220 kV busbar, the installation of a new 600 MVA 220/220 kV phase shift transformer to regulate grid flows and a 3 200 MVA 220/400 (300) kV step-up transformer. The project will also result in the current 3 × 200 MVA 220/400 (300) kV transformer being refurbished.
Extensive work will also be carried out at the Matambo substation, which will be expanded. A new 400 kV feed supply to the new 400 kV Matambo extension will be built to integrate the 400 kV line from Songo.
