The largest street lighting project in the United Kingdom, costing $323.8 million dollars, will replace and maintain 250,000 streetlights with the smart lighting controls to maintain energy efficiency and provide a more efficient use of energy.
The South Coast Street Lighting private finance initiative, which will take 25 years to complete, stretches across Hampshire, West Sussex and Southampton, and will utilize a smart lighting control, which is connected across the internet via a mobile network.
Work has already started to replace and maintain over 250,000 street lights, illuminated signs and bollards, with 150,000 street lights in Hampshire alone.
Connectivity for the project is being delivered by machine-to-machine service provider Wireless Logic (Buckinghamshire, England). The implementation will be carried out by Mechanical & Electrical contracting company SSE Contracting (Perth, Scotland), which is part of Scottish and Southern Energy Group.
According to Wireless Logic, the initiative will aim to utilize up to date, energy efficient equipment, reduction current energy levels, improve visibility, reduce light pollution at night and limit burning hours by dimming lights by 25% to reduce carbon emissions.
Mayflower Complete Lighting Control System (London, England), a highway lighting management system, will monitor and control the system.
The Lighting system utilizes a ‘Zigbee Mesh’ local radio network with ‘nodes’ on each lighting unit that connect wirelessly to a sub master control. Each one of the sub masters communicates with up to 500 nodes, with the sub master in turn connected to the client central server across the mobile network, according to Wireless Logic. Mayflower enables remote management of the entire lighting both in real-time and to preset conditions. The central server reports on energy usage, failed units, and can control the light level element (brightening/dimming) of light clusters in defined areas, entirely remotely, says the company.
“M2M connectivity is critical to the success of the project,” says Gary Kirkland, technical and software manager of Mayflower.
