Electrification That Delivers on Development

By Anteneh G. Dagnachew , Nicolo' Stevanato & Edo Abraham

Sub-Saharan Africa (SSA) faces a dual challenge: a rapidly growing population driving food demand up by an estimated 55% by 2030, and an agricultural sector that underperforms. Smallholder farmers account for 80% of agricultural production, yet rely overwhelmingly on rainfed cropland and hand tools, producing maize yields of around two tonnes per hectare;, less than a quarter of yields achieved in the Americas.

The consequences of this productivity gap extend beyond food security: agricultural growth in SSA is thought to be considerably more effective at reducing poverty than non-agricultural growth, with one study estimating that 73% of the impact of income increases in SSA would derive from improved crop yields rather than other sectors. Closing the yield gap therefore matters not only for food production but as the most direct pathway to poverty reduction available to the region. Energy is a key but underutilised lever for this, enabling irrigation, mechanised processing, and storage simultaneously, yet it has received comparatively little attention in agricultural planning frameworks.

Energy access itself remains deeply unequal. As of 2023, over 600 million people in SSA lack electricity, with rural access below 30% compared to nearly 80% in urban areas. Despite progress in connection rates, the ltotal number of people without access continues to rise.

Current electrification strategies are evaluated on connection counts and basic consumption metrics rather than on economic outcomes, and this creates a planning incentive that favours low-tier, minimal access solutions Extending a minimum-tier connection to the largest number of households maximises progress against SDG7, the global target for universal energy access, for every dollar spent. Planning for productive use loads, by contrast, requires larger upfront investment per connection. As long as success is measured by connections rather than development outcomes, planners might rationally favour solutions that underdeliver on the economic transformation that energy access could otherwise enable.

Despite its importance, African agriculture faces substantial productivity challenges, evidenced by one of the largest yield gaps globally in cereal and other food crop production.

A recent paper, in the Journal of Integrative Environmental Sciences argues that rural energy planning in SSA could be reframed: away from treating households as passive consumers of basic electricity services, and toward recognising them as productive economic units whose energy needs include irrigation, crop processing, and enterprise activities alongside domestic uses. The authors describe this shift as integrating productive uses of energy (PUE) into residential electrification planning.

When energy systems include agricultural and household productive loads from the outset, rather than adding them as afterthoughts, they could generate higher and more stable electricity demand, support greater agricultural productivity, improve household incomes, and enhance the financial sustainability of electrification projects. This creates a reinforcing cycle: productive use raises demand, which improves load factors and cost recovery, which makes the project financially viable, which enables lower tariffs for basic users.

The evidence

The research draws on literature and three illustrative cases from rural Tanzania.

The ACRA case shows that a mini-grid (a small local network supplying a village or cluster of villages independently of the national grid) serving nine villages achieved 58% of electricity sales through productive business uses, with 21 milling businesses generating more revenue than 600 household customers combined.

The CEFA/Matembwe Village Company case integrated mini-hydro power with a poultry farm and animal feed factory, creating stable demand and local income simultaneously.

The JUMEME case on Lake Victoria deliberately focused on household micro-enterprises, pairing infrastructure rollout with entrepreneurial training and demand stimulation before electrification arrived, ensuring electricity was immediately channelled into income-generating uses.

Across these cases, productive uses account for the majority of electricity sold in well-performing systems. Load factors, a measure of how steadily a system is used across the day, increase by 30–60%, and the levelised cost of electricity, (the cost per unit over a system’s lifetime,) falls when irrigation loads are included.

The paper also notes that electrification through agro-processing has significant gender dimensions: electric mills reduce daily grinding time for women and girls by one to three hours, freeing time for other productive activities.

The paper acknowledges risks: newly electrified communities often struggle to use electricity productively if not prepared, which can undermine anticipated demand and trigger tariff increases that make electricity less affordable, creating a vicious cycle that further reduces demand. Agricultural intensification through irrigation also risks depleting water tables, a problem compounded by the fact that the low operating costs of solar-powered irrigation systems can inadvertently promote over-extraction when water pricing is not factored into techno-economic assessments. Market access constraints, seasonality of agricultural activities, and unreliable power supply present additional barriers, and the paper is clear that local context, including socioeconomic conditions, water governance, and existing market structures, is critical in shaping whether PUE interventions succeed or fail.

Policy implications

The paper closes with four concrete recommendations: embedding agricultural productive uses into national and local electrification plans from the earliest planning stage; fostering cross-sectoral collaboration between energy, agriculture, and water management; investing in participatory planning that engages communities in identifying their own energy and economic needs; and adapting definitions and metrics for energy access to capture productive uses beyond minimal household consumption. The authors are explicit that energy access is not a sufficient condition for economic transformation, but it is a necessary enabler, and one whose transformative potential is currently being systematically underutilised by planning frameworks focused on connection numbers rather than development outcomes.
