Telensa has provided the city of Doncaster with a smart city wireless control system for energy management of 33,000 streetlights.
Telensa is using low power UNB wireless technology on a major new deployment covering 33,000 LED streetlights in Doncaster, UK. The deployment is part of Doncaster Council’s Smartlight project that will see existing lights replaced by LED luminaires from Urbis Schréder. The new streetlights are wirelessly connected and managed using Telensa’s PLANet system, ensuring lighting levels are set correctly and power consumption is accurately recorded. Doncaster’s Smartlight project will deliver savings of approximately £1.3m annually by reducing energy consumption by 8.7m kilowatt hours and carbon emissions by 4700 carbon tonnes. Doncaster Borough covers 200 square miles and is home to over 300,000 people.
Telensa’s PLANet system consists of telecells plugged into each streetlight, which connect wirelessly to a cloud-based control application via a small number of streetlight-mounted base stations. The central system ensures that streetlights are set to the optimal level for each area and time of night, so that all areas are safe and well lit. Additionally, because the streetlights are connected, local lighting levels can be continuously adapted throughout their 25-year expected lifetime. The system accurately records the power consumption of each streetlight, allowing the council to ensure that it only pays for the energy consumed. The project is expected to reduce the council’s lighting energy bill by half while also providing an improved quality of light.
By connecting lights through a low-cost wireless network, further IoT applications can also be added quickly and cost-effectively. These include using connected streetlights as a communications hub for sensors such as traffic or air quality measurement, to connect new control applications such as smart parking, or integrating lighting-based analytics with other smart city systems.
“We’re delighted that our wireless PLANet Central Management System is part of Doncaster’s ground-breaking Smartlight project,” said Will Gibson, CEO Telensa. “Connecting LED streetlights with smart city control is compelling because it pays for itself with extra savings in energy usage and avoiding needless maintenance visits, whilst giving the flexibility to centrally evolve lighting programmes over time, future-proofing the LED investment.”
“The Smartlight Project is a fantastic scheme which will result in better quality lighting, a reduced carbon footprint and crucial financial savings for the council.” Mayor of Doncaster, Ros Jones, said. “In a difficult economic climate where other authorities are turning off street lights at night or removing some lighting, ours is a resourceful approach that will maintain lighting while providing savings.”
