Regional Electrification Strategies, Grid Expansion and Energy Access in Ghana: A Least-Cost Modelling Approach using OSeMOSYS

This dataset provides supplementary information for the study titled “Regional Electrification Strategies, Grid Expansion and Energy Access in Ghana: An Optimisation Modelling Approach”. The dataset supports replication of the electricity system model developed using OSeMOSYS MUIO v5.3. The model represents Ghana’s electricity sector with regional clustering and focuses on generation expansion, inter-regional transmission, and electricity demand growth from 2015 to 2070. It includes techno-economic parameters, input datasets, and scenario configurations used to analyse four policy pathways: Business-as-Usual (BAU), Transmission and Distribution Loss Target 17 (TDL), Government Target (GT), and a combined pathway of GT and TDL (GT+T).
