Abstract

Recent technological advancements have led to an increase in off-grid communities systems in South Africa aimed at providing sustainable energy solutions. The research employs DiD models to analyse data from off-grid communities before and after the implementation of energy solutions. Robust standard errors are used to account for potential confounders. A significant reduction in electricity costs was observed in treated communities, with a decrease of 30% compared to control areas. The DiD models effectively capture the impact of off-grid community systems on cost-effectiveness, providing actionable insights for policymakers and stakeholders. Policymakers should prioritise further research into scalability and sustainability issues associated with these systems. Model estimation used $\hat{\theta}=argmin<em>{\theta}\sum</em>i\ell(y<em>i,f</em>\theta(x<em>i))+\lambda\lVert\theta\rVert</em>2^2$, with performance evaluated using out-of-sample error.
