Telefónica Tech has deployed 6,300 NB-IoT nodes in Santa Pola, Spain, to enable remote management of municipal LED street lighting. The project, managed by a joint venture between Ferrovial Energía and Iberdrola Clientes, allows for granular control of light levels to optimize energy consumption and maintenance. According to Telefónica, the system enables real-time data transmission from previously inaccessible infrastructure to central monitoring platforms.
How Smart Lighting Transforms Municipal Energy Management
The primary benefit of this deployment is the shift from static lighting schedules to demand-based operation. By using Narrowband IoT (NB-IoT) connectivity, operators can adjust individual street lights based on footfall or local events. According to Dario Cesena, Director of IoT at Telefónica Tech, this connectivity allows municipalities to make data-driven decisions that replace manual inspections with automated monitoring.
The Santa Pola project is not an isolated experiment. Tellink, the manufacturer providing the control nodes, reports that it has successfully deployed similar smart lighting technology across more than 100 contracts, providing a proven technical foundation for this municipality.
Why Cities Are Adopting NB-IoT for Urban Infrastructure
NB-IoT is favored for municipal lighting because it transmits data effectively even from hard-to-reach areas, such as dense urban centers or remote coastal zones. According to Tellink CEO Dionisio Martínez, the scale of this roll-out requires a specific learning curve regarding regular system updates and controller management. Unlike legacy systems that require physical site visits to address outages, this digital infrastructure detects faults in advance. This predictive maintenance model reduces the time crews spend on routine checks and improves service quality for residents.
What Are the Long-Term Environmental and Financial Impacts?
Santa Pola is targeting a reduced carbon footprint as part of a broader digitalization strategy for its public services. Loreto Serrano, the Mayor of Santa Pola, states that the town council views the renewal of public lighting as a major investment aimed at achieving substantial cost savings. By dimming lights in areas with low activity and adjusting for crowd density, the municipality reduces both energy waste and light pollution. This aligns with broader European trends toward “smart city” certification, where energy efficiency metrics directly influence municipal sustainability rankings.

Frequently Asked Questions
How does NB-IoT connectivity help street lights?
NB-IoT provides a reliable, low-power connection that sends data from sensors on individual street lights to a central platform, allowing for remote monitoring and adjustments without needing high-bandwidth cellular networks.
Who manages the lighting in Santa Pola?
The system is managed by a joint venture between Ferrovial Energía and Iberdrola Clientes, utilizing technology provided by Telefónica Tech and Tellink.
Can smart lighting reduce light pollution?
Yes. By dimming lights during periods of low activity, municipalities can significantly reduce light spill into the night sky, which is a key goal for sustainable urban planning.
