Modernization of public lighting (also referred to as a retrofit) such as replacing high-pressure sodium lamps with LED ones, burdens the budgets of municipalities. For that reason such investments are usually made in phases, spanned over a period of several years, which scopes are determined by financial resources. It should be remarked that selection of lamps for modernization is based on various criteria such as lamp aging, power efficiency of an installation but also some high-level objectives such as a payback period of an investment. In this work we propose the scalable computational, graph-based approach which enables optimizing lamp modernization schedule, towards reduced payback time. The presented results are based on analysis of real-life data of nearly 10,000 streetlights.
