Shifting Financing Landscape for African Power Projects
For years, financing electricity generation across much of the continent relied on a simple formula: a state‑owned utility signed a long‑term power purchase agreement (PPA) with an independent power producer, often backed by a government guarantee. This structure gave lenders confidence because repayment depended on a single, credit‑worthy buyer and a stable price over 15‑ to 25‑year horizons.
Today, analysts at Standard Bank’s Corporate and Investment Banking (CIB) division say that while the traditional PPA model remains important, it is no longer the only pathway to bankable power projects. The definition of “bankability” is expanding as lenders look for revenue resilience across multiple customers and contract types.
The Traditional Power Purchase Agreement Model
Historically, African power projects followed a vertically integrated approach:
- State utilities acted as the sole offtaker, buying electricity at a fixed price.
- Governments frequently provided solvency guarantees, stepping in if the utility faltered.
- Lenders assessed risk mainly on the utility’s financial strength—or the sovereign’s backing—rather than market dynamics.
This model worked well in markets where generation, transmission, and distribution were controlled by a single entity, simplifying both contracting and financing.
Diversifying Revenue Streams
According to Vincenzia Leitich, Executive Vice President of Power and Renewable Energy Client Services at Standard Bank CIB, the evolving market is prompting lenders to evaluate a broader set of commercial arrangements.
“Traditionally, many African energy projects have relied on grid offtake, long‑term PPAs and government guarantees. This model remains important, but it is no longer the only route to market.”

Lenders now consider:
- Long‑term electricity supply contracts with private consumers such as mines, industrial plants, and data centres.
- Participation in electricity trading platforms that match multiple producers with multiple buyers.
- Mechanisms like wheeling—using the grid to transport privately generated power to distant consumers—and open‑access rules that allow direct trades over existing infrastructure.
These alternatives enable a project to sell power to several counterparties, reducing reliance on any single buyer and improving revenue stability.
Real‑world examples are already emerging. In South Africa, large mining houses have signed direct PPAs with solar and wind farms, bypassing the national utility Eskom for a portion of their power needs. Similar trends are reported in Zambia, where private industrial parks negotiate power supplies with independent producers, and in Namibia, where mining firms contract directly with renewable developers.
Transmission Constraints Remain a Critical Hurdle
While financing structures are diversifying, the physical ability to move electricity from where it is generated to where it is consumed remains a bottleneck. Africa hosts some of the world’s best solar and wind resources, yet many of these sites lie far from major load centres.
The International Energy Agency (IEA) notes that global electricity grids are under increasing strain, with delays in delivering key components such as power transformers and high‑voltage cables limiting expansion efforts [IEA, 2024]. In African markets, the challenge is amplified:
- Transmission lines often need to span hundreds of kilometres to connect remote renewable hubs to urban and industrial demand.
- Insufficient capacity can lead to curtailment, voltage instability, or outright project delays, directly affecting the revenue forecasts that lenders rely on.
Without adequate grid infrastructure, even the most financially robust projects risk underperformance.
Policy Responses and Infrastructure Plans
Governments and regulators are beginning to address the transmission gap. In December 2025, South Africa’s Minister of Energy, Kgosientsho Ramokgopa, announced the pre‑qualification of bidders for new transmission lines aimed at alleviating bottlenecks and supporting the integration of recent generation projects [South African Department of Energy, 2025].
Other countries are exploring similar measures:
- Zambia’s Energy Regulation Board is drafting open‑access rules that would allow private traders to use the national grid for wheeling power.
- Zimbabwe is studying public‑private partnerships to upgrade key corridors linking the Hwange thermal complex to the growing solar belt in the south.
- Namibia’s utility, NamPower, has launched a feasibility study for a high‑voltage direct current (HVDC) line to transfer wind power from the coastal Lüderitz region to inland mining hubs.
These initiatives signal a recognition that financing innovation must be paired with infrastructural investment to unlock the continent’s full renewable potential.
Conclusion
The African power sector is undergoing a transition from a reliance on single‑buyer, government‑backed PPAs to a more diversified financing ecosystem. Lenders are now evaluating projects on the strength of multiple revenue streams, the flexibility of contract structures, and the resilience of cash flows against buyer‑specific shocks. At the same time, transmission capacity remains the decisive factor that can either enable or constrain this evolution. Continued policy support, targeted grid investments, and innovative market mechanisms will be essential to ensure that Africa’s abundant renewable resources can be reliably delivered to the industries and communities that need them.
