LED Street Lighting Best Practices: Lessons Learned from the Pilot LED Municipal Streetlight and PLN Substation Retrofit Project (Pilot LED Project) in Indonesia

Energy-efficient light-emitting diode (LED) street lighting technologies and designs can cut energy costs and reduce greenhouse gas emissions. ADB, the Ministry of Energy and Mineral Resources of Indonesia, and the country's state-owned electric utility have collaborated on the implementation of a pilot LED retrofit project. This report describes the applied methodologies, measured results, and lessons learned from the project, which demonstrated average savings of 50% in street lighting electricity costs for two municipalities. It also identifies barriers to scaling up LED street lighting retrofits in Indonesian municipalities, along with technical and policy recommendations that can be implemented to overcome these barriers.
