This paper aims to raise awareness of the municipal electricity debt crisis in South Africa and provide an analytical understanding of the administrative, financial, and governance factors driving it. It further develops a framework to improve municipal electricity debt management, revenue generation, and collection in support of sustainable service delivery. The study adopts a qualitative approach, drawing on secondary data published between 2018 and 2026 and applying thematic analysis to examine the systemic factors, patterns, and trends contributing to the rise in municipal electricity debt. The findings indicate that South Africa’s municipal electricity debt crisis is a systemic outcome of sustained Public Financial Management (PFM) failures, driven by administrative inefficiencies, weak financial governance, political interference, socioeconomic constraints, and poor policy enforcement rather than isolated technical problems. In response, the paper proposes a PFM-grounded municipal electricity debt management framework that integrates improved administrative systems, credible budgeting, strengthened governance and accountability, effective credit control, and the alignment of social policy with revenue management. These elements collectively aim to support long-term financial sustainability and reliable service delivery. The core contribution of the study lies in advancing a coherent, practice-oriented model that links financial governance reform with pro-poor service delivery imperatives, thereby moving beyond descriptive accounts toward an integrated strategy for long-term municipal financial sustainability.
