With 13.3 TWh consumed annually for public lighting in Brazil, there is vast potential for modernization through LED technology, remote management systems, and sustainable financing models.
The EPE (Energy Research Office), in partnership with the Ministry of Cities, recently published a strategic study that provides a new perspective on Brazil’s urban lighting system. With an annual consumption of 13.3 GWh, the sector accounts for 2.4% of total national energy demand, highlighting a critical opportunity to implement energy efficiency policies that could transform municipal budgets.
The document, titled “Public Lighting as a Vector for Digital Transformation and Energy Efficiency in Cities,” notes that current lighting infrastructure lacks technological standardization and modernization. The goal is to integrate these assets into the smart city concept, utilizing municipal streetlights and grids to support essential digital services, optimizing public spending, and improving urban quality of life.
Technology as an economic lever
Massive replacement with LED lamps is just the first step. The distinction proposed by EPE lies in the adoption of remote management, a technology that allows for monitoring and controlling each light point remotely. This capability drastically reduces operational costs by enabling immediate fault identification and predictive maintenance of equipment.
Modernization is not limited to replacing fixtures; it requires the creation of a national database that finally allows for precisely measuring energy efficiency potential and comparing results across different municipalities in the country.
Smart Cities and connected infrastructure
Lighting infrastructure can serve as a foundation for a range of sensors focused on public safety and urban mobility. Thanks to recent changes in regulations regarding the application of COSIP (Contribution for the Cost of Public Lighting Service), municipalities have gained the legal certainty needed to invest in systems that go beyond just lighting streets, including the monitoring of public spaces.
For this evolution to occur, EPE emphasizes the need for system interoperability. The use of open standards is essential to prevent municipalities from becoming dependent on proprietary technologies, ensuring that data governance remains transparent and scalable as city demands grow.
Funding challenges and next steps
The study details that investment bottlenecks can be overcome through a mosaic of financial solutions. From traditional public-private partnerships (PPP) to support from institutions such as BNDES, the Climate Fund, and ANEEL programs, viable paths exist even for smaller locations. This diversity of models allows each city to choose the format that best suits its fiscal health.
The report’s conclusion reinforces that modernization must be viewed from a multisectoral perspective. Collaboration between agencies and institutions such as ENBPar, Unicamp, ABNT, and Inmetro signals that Brazil is pursuing a structured path forward. The next step is the consolidation of a national database and the clear definition of performance indicators, ensuring that investments in clean energy result in more efficient, secure, and connected cities.
