Namibia’s energy infrastructure is shaped by distance. A small population is spread across a large territory, major mines operate far from the main cities, and the strongest renewable resources are often located far from existing demand. The national system must connect distant regions, support cross-border trade, serve new industrial projects and extend basic access to communities that remain outside the grid.
That task has become more urgent as Namibia tries to reduce its dependence on imported electricity. Domestic generation is growing, but the country still relies heavily on the Southern African regional market. New transmission lines, substations and battery systems are consequently becoming as important as new power plants.
A Long National Grid Must Serve Very Different Loads
NamPower sits at the centre of Namibia’s electricity infrastructure. Its role covers generation, transmission, energy trading and parts of supply, while regional electricity distributors and local authorities manage much of the distribution system.
The grid has historically depended on a limited number of large assets. The Ruacana hydroelectric station in the north is the main domestic generator, but its output varies with water conditions in the Kunene River. Other generation is spread among thermal plants, solar facilities and independent power producers. Electricity may therefore need to travel long distances from where it is available to where it is needed.
The network must also serve different types of demand. Windhoek is the main urban load centre, while the Erongo Region contains mines, ports and industrial activity. Southern Namibia is attracting interest in solar power, mining, green hydrogen and future petroleum development. Infrastructure planning must anticipate demand that could grow quickly in areas that were previously lightly supplied.
Regional Interconnectors Form Part of the Security System
Namibia is connected to the Southern African Power Pool, making regional infrastructure central to national energy security. Electricity enters from South Africa, Zambia and Zimbabwe, while the Caprivi Link connects the main Namibian network to the northeast and the wider regional system.
Imports supplied an average of about 58% of Namibia’s electricity requirements in 2023, although the share fell to about 48% in the following financial year. Reliance can rise sharply when Ruacana output is low or demand peaks. Interconnectors are therefore part of the normal operating model rather than emergency assets.
Regional trade provides flexibility but also exposes Namibia to shortages, contract changes and higher prices elsewhere. The national response is to combine stronger domestic generation with more transfer capacity and a wider range of trading partners.
Planned links include new connections with Angola and Botswana and participation in the proposed Zimbabwe-Zambia-Botswana-Namibia interconnector. The Angola-Namibia project could bring additional hydropower into the country while creating opportunities for two-way electricity trade and wheeling revenue.
The 400 kV Backbone Is Being Reinforced
The commissioning of the 290-kilometre Auas–Gerus 400 kV line in April 2024 was a major step in strengthening the grid. Running between the Auas substation near Dordabis and Gerus near Otjiwarongo, the line supports transfers between central and northern Namibia, reduces losses and adds contingency capacity. It also improves the route toward the Gerus–Zambezi high-voltage direct-current connection.
Attention is now shifting to the Auas–Kokerboom corridor. This project is designed to strengthen the connection between central and southern Namibia, where renewable generation, mining demand and large industrial proposals could place greater pressure on the existing network. The line is a central part of the Transmission Expansion and Energy Storage Project, supported by a $138.5 million World Bank financing package.
The wider program includes new or upgraded substations around Windhoek, Erongo and the central coast. These investments are intended to serve existing consumers, mines and new renewable projects. Namibia’s grid expansion is therefore being planned around economic geography as much as population geography.
The main challenge is sequencing. Generation projects can be developed faster than major transmission corridors, but electricity has limited value if it cannot reach the grid or customer. Power plants, industrial projects and network construction must advance together.
Battery Storage Adds Flexibility to the System
Battery energy storage is becoming a new layer of national infrastructure. The Omburu project is planned as a grid-connected system of approximately 51 MW and 51 MWh, while the Lithops project near Arandis is designed at 45 MW and 90 MWh.
These systems will shift electricity between times of surplus and shortage, support frequency and voltage, supply emergency power and reduce the need to buy expensive electricity during peak periods. They will also make it easier to integrate additional solar and wind capacity.
Lithops has particular value because of its location in the Erongo Region, close to mining and industrial demand. Its two-hour storage duration offers more ability to manage evening peaks and sudden changes in renewable output. Omburu, positioned within the central network, can provide broader grid-stability services.
Storage also changes how imported electricity can be used. Power purchased when regional prices are lower can be stored and released when demand or prices rise, strengthening both renewable integration and trading flexibility.
Mining, Ports and Hydrogen Are Redrawing the Load Map
Namibia’s next infrastructure cycle will be influenced by projects that consume much more electricity than ordinary commercial growth. Uranium and other mines already create concentrated loads in Erongo. Proposed green-hydrogen projects in the south could require dedicated renewable generation, desalination, transmission lines, pipelines and port facilities.
Walvis Bay is the main logistics gateway for fuel imports and industrial equipment, and it could support future hydrogen-derived products or offshore oil activity. Lüderitz and the surrounding southern region may take on a larger role if planned hydrogen and renewable projects proceed.
These developments may create private or project-specific systems alongside the public grid. The policy question is how much infrastructure should serve individual projects and how much should reinforce the national network. Shared transmission, substations and port facilities could lower costs and create wider benefits, but they require coordinated planning and credible long-term demand.
Electricity Access Remains a Separate Infrastructure Challenge
Large transmission projects do not solve Namibia’s access gap by themselves. In 2023, about 59.5% of households had electricity access: 46.9% through the grid and 12.6% through off-grid solar. The gap is greatest in rural areas, where settlements are dispersed and conventional extensions are expensive.
Namibia aims to raise electrification to 70% by 2030. The approach combines grid densification, extensions to peri-urban settlements, mini-grids and standalone solar systems. Many unconnected households are relatively close to existing infrastructure, creating opportunities for lower-cost last-mile connections. More remote communities will require decentralized solutions.
Affordability is as important as distance. A line may pass near a settlement while households remain unable to pay connection, wiring or equipment costs. Progress will depend on financing models, subsidies, reliable standards and maintenance capacity as well as construction.
Namibia Is Building Toward a Regional Energy Role
Namibia’s strategy is moving in two directions at once. One is domestic: stronger north-south transmission, battery storage, new substations and wider access. The other is regional: more interconnectors, greater trading capacity and infrastructure capable of supporting export-oriented energy industries.
If the major corridors, storage projects and regional links are delivered in sequence, Namibia can reduce import vulnerability without giving up the advantages of the Southern African market. Its system could then develop from a mainly import-dependent network into a flexible corridor connecting renewable resources, mines, ports and neighboring countries.
