Africa’s energy conversation has long been dominated by generation plants commissioned, solar farms inaugurated, and gas turbines procured. Comparatively, little attention has been paid to transmission: the infrastructure that actually moves electricity from where it is produced to where it is needed. This gap is one of the continent’s most consequential infrastructure deficits. The Public-Private […]

Africa is home to some of the world’s cheapest electricity.

For a mini-grid developer, the distinction between fixed and variable costs is not just accounting language; it shapes tariff design, profitability, debt repayment planning, and long-term sustainability. For lenders […]

In the mini-grid ecosystem, financial sustainability is often discussed in terms of grants, concessional capital, and blended finance structures. While these instruments are important in de-risking early-stage projects, they do not determine long-term viability. Once operational, mini-grids survive primarily on two revenue streams: connection fees and tariffs collected from electricity sales. The stability of these revenues depends fundamentally […]
