Sustainable mini-grid model as an alternative energy source for deprived communities in Ghana

Access to reliable electricity remains limited in rural Ghana, constraining socio-economic development. This study examined the perception of households on sustainable mini-grid models as an alternative energy source for deprived communities in the Ashanti Region. Using a descriptive design, data were collected from 156 respondents in two rural communities through cluster and simple random sampling. Load profiles were developed for residential, institutional, commercial, and industrial demand. Results show mini-grids significantly improved energy access, supporting petty trading, education, healthcare, and reducing kerosene dependency, while also promoting environmental benefits. However, challenges such as regulatory bottlenecks, limited productive electricity use, and cultural conservation practices hinder long-term viability. Affordability was positively associated with income, indicating the need for adaptive tariff structures. The study recommends strengthening regulatory frameworks to encourage private investment, promote productive use of electricity, and integrate clean cooking solutions to maximize socio-economic and environmental benefits while ensuring long-term sustainability.
