Increasing Uganda’s low electrification rate is one of the country’s major challenges. Power service is essential to achieve socioeconomic development and poverty reduction, especially in rural areas. This paper shows the advantages of using an integrated (grid and off-grid) electrification model with high geospatial, temporal, and customer-class granularity as the Reference Electrification Model (REM). In universal electrification strategies, REM will help better ascertain the role of minigrids, jointly with grid extension, solar kits, and stand-alone systems. REM has been applied to the Southern Service Territory (SST) to determine the least-cost mix of electrification modes—grid extension, off-grid minigrids, and standalone systems—that satisfies the hourly demand requirements of each customer—residential, commercial, or industrial—considering its individual location. REM incorporates the existing grid layout, the hourly solar local profile, and the catalogs of actual components for network and generation designs. The paper shows that minigrids can provide grid-like service at a significantly lower cost in many circumstances and to a considerable extent. Therefore, minigrid strategies should play a more important role in electrification planning, both transitorily and on a permanent basis, particularly when the central grid suffers from frequent and prolonged blackouts.

Achieving universal access to energy by 2030 (Sustainable Development Goal 7.1) hinges on significantly scaling up and accelerating electrification efforts in developing countries. Governing the ecosystem of government agencies, energy utilities, practitioners, development and finance institutions, banks, NGOs, academia, and, most importantly, beneficiary communities to accelerate the pace of electrification requires the interweaving of technological innovation, disruptive business models, improved institutional frameworks, and inclusive multi-stakeholder decision-making, to ensure that no one is left behind. The foundation of this article is based on extensive insider research, including 14 national electrification plans, numerous visits, field studies, and semi-structured interviews with these actors conducted over ten years in 25 countries. This article presents a novel comprehensive conceptual approach that integrates both macro (national and global) and micro (local and individual) level mechanisms and the role of cultural factors and shared values within the ecosystem in driving and accelerating action within a harmonized regulatory, policy, and planning framework. It outlines the essential mechanisms for effectively engaging and empowering governments, utilities, donors, and local actors to accelerate the path to universal electrification through the most cost-effective articulation of diverse technologies and business models.
