Mozambique's state utility Electricidade de Moçambique (EDM) has issued a public tender for a 400 kV high-voltage transmission line project, covering design, supply, installation, and commissioning. The call for proposals marks an active procurement phase, meaning qualified contractors and suppliers can formally respond to the opportunity now.
The 400 kV voltage class is characteristic of backbone transmission infrastructure — the kind of grid capacity required to evacuate power from large-scale generation sources, including the gas-to-power projects associated with Mozambique's expanding LNG sector in the Rovuma Basin. While the tender notice does not specify the line's routing, length, or total project value, the scope — design through commissioning — suggests a full engineering, procurement, and construction (EPC) or EPC-adjacent package rather than a narrowly defined supply-only contract.
Mozambique has significant electricity infrastructure deficits despite sitting atop one of Africa's largest natural gas reserves. EDM has been progressively expanding its transmission network to connect generation assets to industrial and population centres, and to integrate with regional power pools including the Southern African Power Pool (SAPP). A 400 kV line would represent a meaningful upgrade to national grid capacity and could support both domestic electrification targets and cross-border power trade ambitions.
For companies operating in the energy infrastructure space, the tender represents a direct entry point. The design-supply-install-commission scope opens roles for grid engineering specialists, high-voltage equipment suppliers, civil and electrical construction contractors, and project management firms with African power infrastructure experience. Norwegian-linked companies with competence in offshore and onshore energy infrastructure, particularly those that have built capabilities in harsh-environment cable and power systems through North Sea operations, may find transferable value here. The tender is open now, and the relevant next step is obtaining the full tender documents from EDM to assess technical specifications, qualification criteria, and submission deadlines.
