Southern Africa does not lack power potential; it lacks the wires, the rules and the reach to move what it generates to where it is needed. A region with world-class solar resource, large hydro endowments and growing gas finds still leaves a substantial share of its people without a reliable connection, and its national grids too often stop at the border. That is the gap the region’s energy ministry tried to close in February, choosing the setting deliberately. Hosting the gathering in Victoria Falls put the conversation within sight of the Zambezi, the river whose hydropower already crosses borders to keep lights on across several countries.
The Mandate: Interconnect or Stay Marginal
At SADC Sustainable Energy Week, held in Victoria Falls from 23 to 27 February 2026, delegates put regional interconnectors at the top of the agenda — naming the Angola–Namibia, Malawi–Mozambique and Tanzania–Zambia links specifically. The logic is straightforward. A country with surplus generation at midday and a neighbour short of power in the evening together form a more stable system than either does alone. Interconnectors turn isolated national grids into a tradeable regional market, smoothing surpluses and shortfalls across borders. The three corridors named at the meeting — Angola–Namibia, Malawi–Mozambique and Tanzania–Zambia — each stitch a country with generation into one without enough of it, extending a pooled market that the region’s existing power-sharing arrangements have only partly built. Power that cannot cross a frontier is power half-used.
The Target: Universal Access by 2030
The second pillar was a commitment to universal electricity access by 2030, delivered not only through grid extension but through mini-grids and rooftop solar. This is the pragmatic part. Stringing transmission lines to every dispersed rural settlement is slow and expensive, and for many communities a solar mini-grid reaches them years sooner and at lower cost. For Zimbabwe, where grid reliability has constrained both households and industry, decentralised generation is less a fallback than a parallel build-out that can run ahead of the national network. Rooftop solar also shifts some of the financing burden onto households and firms rather than the utility alone, and a mini-grid can be sized to a single community’s load rather than waiting for national transmission to reach it. Access delayed until the grid arrives is access denied for a decade.
The Plumbing: Harmonised Rules
The least visible priority may matter most. Delegates pushed for harmonised regulation across the region, and without it the rest stays on paper. An interconnector between two countries is only as useful as the agreement that governs who pays, who dispatches and at what price electricity flows. Divergent licensing regimes, tariff structures and technical standards are exactly what stall cross-border projects for years. Harmonisation is the unglamorous work that decides whether a signed memorandum becomes a live cable. The hardware is the easy part; the rulebook is where projects live or die.
The Zimbabwe Read: From Importer to Node
For Harare, the implications are concrete. Zimbabwe sits at the centre of the regional map, already linked into the Southern African Power Pool and dependent at times on imported electricity to cover its own shortfalls. A denser interconnector network and harmonised rules would let it both import more reliably in deficit and, as its own generation grows, export surplus rather than strand it. The 2030 access target, meanwhile, sets a measurable bar that Zimbabwe’s rural electrification effort can be held against. The country’s advantage is geography: a well-connected centre can become a trading hub rather than a perennial buyer. The grid that reaches furthest, and the rules that travel with it, will decide who powers the region’s next decade.
