Kent Council rakes in savings with massive LED project

30,000 P852 lanterns have already been installed in Kent, taking the average energy consumption from 469KW on the existing HID asset to 117KW.

Kent County Council is the process of converting thousands of street lights, lit signs and bollards to LED, a large-scale project that is set to save the local authority millions in the medium to long-term by cutting energy consumption by up to 70 per cent.

The Council is one of the largest lighting asset authorities in the UK with 118,000 street lights and 25,000 lit signs and bollards. The annual cost of illuminating and maintaining this stock is over £9m, a cost that continues to rise.

The main focus of the ongoing project is to reduce the cost of illuminating and maintaining these light sources by converting them to more efficient LED products.

Bouygues Energies & Services were appointed after a successful tender bid by the council to manage the installation conversion from HID to LED lanterns.

The advantage of producing the luminaires in the UK means that CU Phosco Lighting, who are providing the technology for the project, can react quickly to any site changes or deviations that can occur. This assists the contractor in improving efficiencies in the program as well as reducing any delays to the road schedule.

During the supply of the luminaires CU Phosco Lighting and Bouygues Energies & Services are working in partnership with their design consultant (Designs for Lighting) to a forward planned site schedule ensuring minimal distribution to the road network and public users.

The production programme was assisted by Designs for Lighting who designed every asset to ensure compliance with standards and optimised energy efficacies, the luminaires used were carefully considered for efficiency and maintenance and concluded that five versions of the P852 to be used with two optics. This enabled a much more efficient production and installation programme.

The project commenced in March 2016 and is on a three year rolling project starting in residential areas, which are to be completed by the second half of 2017. Then eventually moving to the main roads and highways in the summer of 2017 and to be completed by December 2018.

The improvement in light quality from HID to LED is evident across the districts that have been installed so far. The P852 provides exceptional optical control minimising obtrusive light, without compromising the lighting performance for both road and pedestrian use.

30,000 P852 lanterns have already been installed taking the average energy consumption from 469KW on the existing HID asset to 117KW for the P852 LED light source this equates to circa 70 per cent energy reduction.
