A Strategic Framework Agreement signed in Kinshasa on 6 October puts a privately led cross-border line on Africa's most power-hungry mining corridor. The Kalumbila-Kolwezi Interconnector Project will run about 200 kilometres between Kalumbila in Zambia and Kolwezi in the Democratic Republic of the Congo, with a thermal capacity of 700 MW and room to grow above 1 GW. The parties put construction cost at about USD 300 million. The Strategic Investment Fund of the DRC, Enterprise Power DRC (EnPower), Trafigura and Gridworks Development Partners will jointly finance, build and operate the line, with Gridworks as lead equity investor and Trafigura arranging a large share of the debt. EnPower is already a licensed Congolese power trader and a Southern African Power Pool member. The project has its concessions, licences and authorisations in place.
The announcement matters less as a single corridor than as evidence of a financing pattern that Africa's master plans have struggled to produce. Continental and regional grid programmes are plentiful. What has been scarce is the step from a marked corridor on a map to a signed financing agreement with a creditworthy payment structure. KKIP, Kenya's first transmission PPP, Uganda's Amari independent transmission project and Mozambique's Chimuara-Nacala prequalification sit in that narrow band of deals that treat wires as bankable infrastructure rather than as residual utility capital expenditure.
What the line is meant to do
The Congolese Copperbelt has a structural power deficit of more than 1 GW, according to the parties. Mines and refiners that need firm, competitively priced electricity have sat behind that gap. KKIP is designed to import up to 550 MW into the Kolwezi area from the Southern African Power Pool, using Zambia as the entry point. For Zambia, the same line opens an export path for licensed producers and a reason to build more generation behind a firmer wheeling route. For both governments, the commercial anchor is mining offtake, with spare capacity on the line intended for wider loads once the corridor is energised.
That structure is familiar from other African interconnectors, but the ownership is not. EnPower presents KKIP as the first privately developed and financed cross-border transmission project on the continent. Gridworks, owned by British International Investment, takes the majority equity role. FIS-RDC, created by decree in October 2025, makes this its inaugural announced investment, casting sovereign capital as a catalyst beside private sponsors rather than as the sole buyer of last resort. Discussions with Zambian co-investors are under way. The International Finance Corporation is cited among the stakeholders that supported development.
The wider transmission bottleneck
The timing sits beside a louder diplomatic track. On 23 September in New York, UN Secretary-General Antonio Guterres launched the Global Grids Accelerator, convened by UNDP, UNOPS and Sustainable Energy for All, with an initial focus on Africa and South-East Asia. The Accelerator does not create a new financing institution. It is meant to broker policy, project preparation, finance and delivery around grid priorities that governments already name. Guterres framed grids as the arteries of the energy transition. The supporting numbers are familiar to planners: more than 2,500 GW of renewable projects stalled in connection queues worldwide, annual global grid investment near USD 450 billion needing about a 50 per cent rise by 2030 on IRENA's reckoning, and IEA estimates that more than 80 million kilometres of grids must be added or refurbished by 2040.
Africa's share of that investment remains thin. The IEA's World Energy Investment 2026 outlook, as reported by ESI Africa, puts African energy investment at about USD 110 billion in 2026, roughly 3 per cent of the global total for a fifth of the world's population, or about USD 68 per person against a global average near USD 396. Global spending on electricity networks is put at about USD 550 billion this year. Earlier IEA analysis cited in the same reporting said African grid investment needs to rise from about USD 10 billion a year toward nearly USD 50 billion by 2030 if access and climate goals are to hold. More than 60 per cent of African state-owned power utilities operate at a loss, according to AfDB and IMF figures cited by ESI Africa, which is why finance ministries resist blanket sovereign guarantees for long transmission builds.
South Africa illustrates the physical side of the same gap. Electricity minister Kgosientsho Ramokgopa has said the country is not short of megawatts but of grid capacity, with more than 130 GW of generation projects stalled by limited network access. At Windaba he put curtailment losses near R49 billion a year. On 7 October he front-loaded a ministerial determination for 4,600 MW of batteries and 5,000 MW of gas-to-power under IRP 2025, with no new wind or solar in that round, precisely because midday surplus cannot reach evening demand on a constrained network. Surplus without wires is still a shortage for the hour that matters.
Deals that reached paper
Against that backdrop, a short list of transactions has begun to show what bankable transmission looks like when the utility balance sheet cannot carry it alone.
In December 2025, Kenya Electricity Transmission Company signed what it called Africa's first transmission PPP: a 30-year concession with Africa50 and India's Power Grid Corporation, worth about USD 311 million and requiring no public funding, covering a 400 kV line for the Baringo-Silali geothermal corridor and a 220 kV line in western Kenya. Uganda amended its Electricity Act to admit private transmission investors. Gridworks' Amari project, presented as the continent's first independent transmission project to reach financial close, broke ground in July 2026. Tanzania has signed an MoU with Africa50 on transmission PPPs. South Africa's Independent Transmission Projects programme has prequalified seven consortia for a first phase of about 1,164 km of lines across seven corridors, valued around USD 1 billion, with availability-based payments under 25-year contracts through the National Transmission Company South Africa's Central Purchasing Agency.
Those deals share a pattern: a clear legal path for private ownership or concession, a payment counterparty that investors will underwrite, and availability payments that remove volume risk from the wire owner. Generation projects still need firm evacuation. Without predictable transmission cash flows, they carry higher risk and weaker bankability, a point TAQA Arabia's Pakinam Kafafi made in the ESI Africa reporting on the Accelerator.
Mozambique is adding another test case. On 9 October, Gridworks affiliate GW Mozambique Investments LLP and Eletricidade de Mocambique opened contractor prequalification for the Chimuara-Nacala Power Transmission Line, with bids due by 24 November. The package covers about 460 km of line: 272 km of 400 kV between Alto Molocue and Namialo, 98 km of 220 kV between Namialo and Nampula, and 92 km of 220 kV between Namialo and Nacala-a-Velha, plus new and expanded substations. Gridworks puts total investment near USD 450 million, says the line should unlock about 600 MW of additional generation and move hydro and solar power north, and positions the project as Mozambique's first privately funded transmission build, developed with EDM. IFC announced support in July 2025 for later phases. The UK had earlier signalled financing support when the project was framed in May 2024.
Planning still has to catch the deals
Regional planning is moving in parallel, if more slowly. From 29 to 30 September in Kigali, the African Development Bank Group and the Eastern Africa Power Pool secretariat ran a workshop on the update of the EAPP Regional Power System Master Plan, financed through the Sustainable Energy Fund for Africa. Utilities from the pool's member countries reviewed demand forecasts, generation and transmission data and gaps. The master plan is the long-term frame for where interconnectors should sit. James Wahogo, EAPP secretary general, stressed that reliable information is the base for investment decisions. Harrison Sungu of KETRACO warned that poor data produces unjustified demand projections. Synchronising SAPP and EAPP, targeted for the end of 2026 in ESI Africa's account, would create a very large cross-border corridor, but ZESCO's Lioko Sitali has cautioned that regional trade stays limited while national backbones remain weak.
That is the practical test for the Global Grids Accelerator and for sponsors such as Gridworks. Africa does not need another catalogue of priority corridors. It needs project preparation money for transmission, standardised independent-transmission contracts that smaller markets can adopt, and credit enhancement where utility payment risk is still too high. South Africa's Credit Guarantee Vehicle, backed by National Treasury and the World Bank, is one model cited in the ESI Africa analysis. Mission 300, the AfDB and World Bank drive to connect 300 million Africans by 2030, will not meet its grid share of new connections if wires remain the residual line item.
What to watch on the Copperbelt
Three markers will show whether KKIP becomes a template or a one-off. The first is financial close and the shape of the debt package Trafigura has agreed to arrange: tenor, security over mining offtake, and how much residual risk sits with FIS-RDC. The second is Zambian co-investment and the export contracts that fill the line from the south, because a 700 MW thermal rating only matters if generators and traders can book firm capacity. The third is how Congolese industrial load beyond the mines gets access once the corridor is live, including tariff and wheeling rules that keep spare capacity from becoming stranded for public loads.
For SAPP more broadly, a privately financed interconnector that strengthens the DRC's tie into the pool is a signal that regional trade can grow without waiting for every national utility to repair its balance sheet first. It does not replace national backbone investment. It does show that where mining demand is large, licences are clear and equity sponsors will take construction risk, Africa can move a transmission line from a master-plan corridor to a signed framework in commercial time. The next twelve months will tell whether Kalumbila-Kolwezi, Amari, Kenya's PPP and Mozambique's LTEC prequalification are the start of a pipeline or a short list that finance ministries still treat as exceptions.
