Smart street light management system ensures energy efficiency while reducing envirnomental impact.

Overview

When street lights become smarter, nights turn safer, skies stay clear, and communities shine brighter — this vision is now a reality in Nottuln!

In a bold move to enhance sustainability and curb light pollution, the municipality has modernised its public lighting infrastructure with Tvilight’s intelligent street lighting solution. By implementing OpenSky Zhaga IoT street light controllers and the CityManager light management platform, Nottuln has significantly improved energy efficiency and operational management.

This initiative supports the town’s ambitious climate neutrality goals for 2030 and has already resulted in over 60% energy savings every night.

Key Objectives

  • Transition from conventional street lighting to modern, energy-efficient LED technology
  • Reduce energy consumption and CO2 emissions to align with climate neutrality targets
  • Implement a smart light management system from remote monitoring and maintenance
  • Minimise operational costs by reducing unnecessary energy use and maintenance visits
  • Enhance public safety and visibility with dynamic lighting control
  • Reduce artificial light pollution to protect the environment and local biodiversity

”With smart lighting solution, we have significantly reduced our energy usage while improving operational efficiency. This is a major step toward our sustainability goals.

Dr. Dietmar ThönnesMayor of Nottuln

Customer Vision

The municipality of Nottuln sought a cutting-edge public lighting solution that would provide significant energy savings while ensuring the well-being of its citizens. With an ambitious goal of achieving climate neutrality by 2030, Nottuln needed a system that could intelligently manage streetlights, optimise energy usage, and integrate seamlessly with the new LED fixtures.

Traditional street lighting posed several challenges, including high energy costs, frequent maintenance requirements, and inefficient illumination. To overcome these issues, the municipality envisioned a smart lighting system that would provide real-time monitoring, dynamic dimming, and remote management capabilities.

Solution

Tvilight offered a comprehensive smart street light management solution tailored to Nottuln’s needs:

  • OpenSky Zhaga IoT Street Light Controllers: Installed on each lighting point, these controllers enable real-time monitoring, remote dimming and dynamic lighting control, reducing unnecessary energy use without compromising safety.
  • CityManager Light Management Platform: This centralised cloud-based platform allows city officials to remotely monitor, manage, and control street lighting. With the help of real-time data, remote diagnostics, and automated fault detection, regular inspection trips are no longer required. The smart lamp controllers enable the street lights to report faults automatically, ensuring on-site interventions are carried out only when necessary, significantly reducing operational costs and maintenance efforts.
  • Integration with New Infrastructure: Tvilight’s solution seamlessly integrates with Nottuln’s newly installed LED streetlights, which were based on the Zhaga Book 18 standard. Because OpenSky IoT controllers are also Zhaga-based, the installation was quick, easy, and tool-free, ensuring that municipality start reaping the benefits from day one!

Outcomes and Benefits

  • Over 60% energy savings per night, drastically reducing the energy bills
  • Nearly 63.7 tonnes of CO2 reduction in the past six months, supporting Nottuln’s climate neutrality goals
  • Enhanced public safety, providing well-lit streets when needed
  • Lower maintenance costs, thanks to remote monitoring and predictive maintenance features
  • Reduced light pollution, protecting the environment, local wildlife and night sky
  • Seamless operation and easy scalability, allowing future expansions and smart city integrations

Conclusion

The smart street lighting project in Nottuln exemplifies how innovative technology can drive sustainable urban development. By integrating intelligent lighting solutions, the municipality has achieved remarkable efficiency gains while reducing environmental impact. This project stands as a model for cities aiming to modernise their infrastructure in a cost-effective and environmentally friendly manner.

”We are investing in the future by converting to smart LED street lights. We are not only saving energy (we expect at least 50 percent), but we are also producing significantly less CO₂. This means we are taking another step towards climate neutrality by 2030.

Dr. Dietmar ThönnesMayor of Nottuln

”With the help of lighting management, operators can check Nottuln’s street lighting and carry out remote maintenance from their desks. Regular inspection trips are no longer necessary. The street lamps automatically report when something is broken, and only then is an on-site intervention necessary.
