Electrical Minigrids for Development: Lessons From the Field

Abstract

| Energy services are crucial to human wellbeing and development, and without reliable energy, it is difficult to escape subsistence lifestyles and poverty. Here, we report on four identical capacity rural minigrid interventions undertaken in Kenya and Uganda with differing socioeconomic characteristics and demographics. The research outcomes presented briefly discuss the preparation stages of the interventions including community surveys that informed the technical design, deployment phases, and setup of the community cooperatives to manage the minigrid projects. The main focus here is on lessons learned, including system design and minigrid performance under various load profiles. The results show a clear and increasing uptake of power by the communities with intensities varying depending on the electricity tariff used.Across the four minigrids, daily electricity growth rates are seen to vary by a factor of 8. The Ugandan minigrids operated at close to utility grid tariff and reached the 28-kWh/day design limit within two years. By contrast, the Kenyan minigrids charged a higher cost recovery tariff, which capped the demand and systems operate below the design limit. These findings have implications not only to system design but also to system stability and longevity. The approach taken here, of community centered cooperatives running the delivered minigrids, is now embedded within the rural electrification authorities/agencies in both countries, with additional similar projects being planned in ramifications, and replication of such a minigrid concept as compared to other approaches are also discussed in this paper.

Hierarchical energy management for community microgrids with integration of second‐life battery energy storage systems and photovoltaic solar energy

“…This can promote the reuse of social resources, reduce energy cost for residents, and enhance demand side's local energy production ability. Such application of second-life BESSs is particularly meaningful for relieving the 'Energy Poverty' issue [13,14], which refers to a global phenomenon that many low-income households are hard to afford the increasing energy cost and are lack of access to modern energy services. This issue becomes more severe due to the global economic recession caused by the current COVID-19 outbreak [15].…”
