Background. Zambia opened part of its electricity market on 19 July 2024 through the Electricity (Open Access) Regulations, Statutory Instrument No. 40 of 2024, which let generators, traders and large consumers use the network outside the single-buyer model. Regulation 5 sets the condition of entry at 1 MW. Work on innovation among energy enterprises in low-income countries has concentrated on what firms are able to do, and has paid less attention to what they are permitted to do.
Methods. This conceptual paper uses theory adaptation and typology construction. Sources were selected under four criteria: peer-reviewed modelling and regulator statistics for quantities, primary legal instruments for regulatory claims, official statistics for household energy, and donor reporting for illustration only. Four segments of the energy economy are compared, separated by incumbent identity, licensing regime and demand structure.
Results. The 1 MW threshold works as innovation policy that nobody has evaluated as such, because it places the radical pathway beyond the reach of every domestic small and medium enterprise in the sector. Pathway distribution across the four segments follows regulatory treatment and incumbent form more closely than firm capability. Grid-adjacent firms work almost entirely within the incremental pathway. Off-grid solar shows frugal activity by domestic firms and radical activity by capitalised foreign entrants. Clean cooking serves most national energy demand and shows the least activity, because it’s incumbent is an informal fuel priced below social cost.
Conclusions. Eligibility rules should be recognised as an integral component of innovation policy. Aggregation would admit small firms to participate without lowering the 1MW technical threshold.
