Building a solar power plant does not automatically guarantee that the electricity it produces will reach paying customers. Developers also need credible buyers, workable power purchase agreements and arrangements for selling and delivering electricity into the market. A new agreement in Zambia between Axian Energy and Africa GreenCo highlights the growing role of power-market intermediaries in connecting renewable energy producers with electricity buyers.
The agreement centres on a power purchase agreement (PPA), under which Axian Energy will supply solar-generated electricity to Africa GreenCo. Rather than relying solely on a conventional arrangement with a single utility, the deal brings a power trader into the commercial structure. GreenCo operates as an intermediary in electricity markets, helping aggregate demand and manage transactions between generators and buyers. The specific commercial terms of the agreement, including the contracted capacity and pricing, should be confirmed against the parties’ full disclosures.
This structure matters because electricity markets across Africa often involve a mismatch between new generation projects and the buyers able to purchase their output. A developer may secure land, equipment and financing, but still face uncertainty over who will buy the electricity, whether payments will arrive on time and how the power will be traded or delivered. An intermediary can help bridge that gap by structuring sales and managing relationships with buyers, although its effectiveness depends on its own creditworthiness, contracts and ability to manage market risks.

Zambia provides a useful setting for this model as it seeks to expand generation and strengthen electricity supply amid pressure on its hydro-dependent system. Solar can add capacity relatively quickly and diversify supply, but converting that capacity into dependable electricity sales requires more than favourable sunlight. Transmission access, grid constraints, balancing arrangements and payment security all affect whether a project can operate commercially. Trading structures can help organise electricity sales, but they do not remove the need for adequate infrastructure or reliable settlement systems.
The wider significance of the Axian–GreenCo agreement is that Africa’s renewable energy market needs to develop the commercial systems around generation as well as the plants themselves. Power traders, aggregators and other intermediaries can help connect projects to buyers and create additional routes to market, particularly where conventional utility procurement is limited. For solar developers, the ability to secure a bankable route to market can be as important as the ability to build the plant. As electricity markets evolve, these arrangements could help determine which projects move from development plans to operating assets.
