UK county looking for major savings from Siemens traffic light upgrade

A major programme to upgrade traffic lights at 78 junctions and 100 pedestrian crossings across Norfolk, in the UK, with new energy-saving LED signals from Siemens is nearing completion. The retrofit project to supply, install and maintain all 178 sites is estimated to provide up to 78 per cent power consumption and carbon savings for Norfolk County Council (NCC). The new contract includes an innovative cost benefit payback solution provided by Siemens Financial Services.

A major programme to upgrade traffic lights at 78 junctions and 100 pedestrian crossings across Norfolk, in the UK, with new energy-saving LED signals from 189 Siemens is nearing completion. The retrofit project to supply, install and maintain all 178 sites is estimated to provide up to 78 per cent power consumption and carbon savings for Norfolk County Council (NCC). The new contract includes an innovative cost benefit payback solution provided by Siemens Financial Services.

According to NCC’s Graham Harbord, team manager, ITS, all new traffic signal installations in Norfolk are equipped with Siemens extra low voltage (ELV) controllers and the benefits extend beyond energy and carbon savings. “Without the need to constantly replace lamps, maintenance costs are reduced and with no mains voltage on site every installation is safer. Overall, Norfolk will achieve significant long-term savings, taking into account the traffic management costs to provide and install the ELV equipment, the power and carbon savings as well as the cost to finance the project,” Harbord said.

Norfolk County Council worked alongside Siemens in identifying sites suitable for LED retrofit head replacement, the number of heads, the number and type of aspects and grouped the locations within the county so that a more efficient delivery programme could be agreed. “This joined up approach will reduce the works period, reduces travel and therefore C02 emissions while delivering the project,” Harbord said.

The finance facility offered to NCC helped enable the entire project to proceed because the savings generated helped make the project ‘self-financing’ and more affordable.

    Siemens extends low-power retrofit solution
    The Siemens LED retrofit portfolio has been extended to allow Peek Elite incandescent traffic signals to be upgraded to low-power Siemens CLS LED technology. Offering carbon and energy savings of over 75 per cent, the newly developed retrofit option follows the success of Siemens's Helios retrofit technology and enables even more existing incandescent signals to be upgraded to modern LEDs, whilst maximising the re-use of existing roadside infrastructure.

    Substantial savings from smarter street lighting
    As authorities strive to reduce expenditure and carbon emissions, Colin Sowman looks at some of the smart ways of managing street lighting while containing costs and maintaining safety. Street lighting can account for 40% of an authority’s energy consumption. So, faced with the need to reduce outgoings, some authorities are looking for smart ways of managing street lighting or even turning off swathes of street lights in the small hours. Back in 2008 the E-street Initiative report concluded that authorities

    Siemens switches US city of Manchester to LED street lights
    Siemens is switching 9,000 street lights to LED technology in the US city of Manchester in New Hampshire. Some 4,500 lamps have already been refitted and the work should be completed by the end of September. Siemens will also be responsible for service and maintenance work. Siemens says LED technology reduces power consumption by 60 per cent and will bring the city considerable financial benefits, with annual savings of US$500,000 in terms of energy and maintenance costs such as replacing light bulbs.
