A High-Resolution Analysis of Electricity Demand for Informed Electrification Planning

Paper i proceeding, 2024

Electrification planning necessitates a nuanced understanding of electricity demand. However, previous studies have largely overlooked regional differences and relied on a one-size-fits-all approach to demand estimation. This study aims to examine the spatial distribution of electricity demand across households and community institutions in a developing country context, using Ethiopia as a case for the study. The study employed a multifaceted approach: household demand was estimated using the Multi-Tier Framework (MTF), while the demand for community institutions (healthcare, education facilities, places of worship, and government offices) was estimated using the Remote-Areas Multi-energy systems load Profiles (RAMP) stochastic model. The spatial distribution was visualized using the OnSSET methodology. The findings reveal significant demand heterogeneity, with 64% of households falling within Tier 1 and Tier 2 demand levels assuming all households have electricity access, but 61.3% of currently electrified households exhibit Tier 3 in 2020. Additionally, community institutions exhibited electricity demand patterns, with health facilities requiring the highest average demand (around 2,100 kWh/year), followed by education facilities (400 kWh/year). Insights from these high-resolution demand assessments can inform the selection of cost-optimal electrification technologies (e.g., grid extension, mini-grids, standalone systems) based on the demand patterns of specific communities at local level in Ethiopia.
