Transitioning from fossil fuel-based to renewable energy (RE) generation is critical for meeting climate goals but entails major socio-economic challenges across the coal–thermal value chain, including job losses, stranded assets, and revenue disruptions. Existing research largely focuses on technical, financial, or environmental aspects, with little attention to these social and economic costs, and no established way to integrate them into formal energy system models. This study proposes a novel and mathematically tractable framework that classifies socio-economic impacts as ‘capital stranding’ per MW of prematurely retired coal capacity and ‘operational stranding’ per kWh of avoided thermal generation . Such classification is designed to enable future inclusion of these costs directly into energy planning models (typically large-scale optimisation models), filling a key gap in current approaches. We apply the framework to Karnataka’s electricity system for 2020, a particularly relevant case as the state has aggressively integrated RE into its grid. While our findings are Karnataka-specific, the framework is adaptable and can be extended to other regions with appropriate datasets, which forms the basis of our ongoing research. By embedding socio-economic concerns into technical planning, this work provides policymakers with tools to design just and inclusive transition strategies that minimize disruptions while advancing sustainability.
