KENT

Kent County Council is one of the largest lighting asset authorities in the UK with 118,000 street lights and some 25,000 lit signs and bollards. The annual cost of illuminating and maintaining the stock is over £9m, a cost that continues to rise. The main focus of the project is to reduce the cost of illuminating and maintaining these light sources by converting them to more efficient LED products. Bouygues were appointed after a successful tender bid by the council to manage the installation conversion from HID to LED lanterns. Incorporated in the drive for more energy-efficient lighting the contract also required a Central Management System (CMS) and Bouygues chose Telematics as the CMS provider on the contract. As part of a tendering process Bouygues enlisted CU Phosco to supply the P852 residential LED luminaire. Designs for Lighting completed the lighting design options and corroborated the projected energy savings for the client.

The P852 fittings are manufactured in Coleford, Gloucestershire to a forward schedule. The advantage of producing the lanterns in the UK means that CU Phosco 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 and Bouygues are working in partnership to a forward planned site schedule ensuring minimal distribution to the road network and public users. The schedule outlines CU Phosco production for quantities and geographical boroughs within the county. This provides clarity for both CU Phosco and Bouygues to maintain delivery of the project in a professional, efficient and organised manner.

The standard P852 luminaire build was modified for Kent County Council with additional features included to meet the council’s specification and approval. The project commenced in March 2016 and is on a three year rolling project starting in residential areas which are to be completed within Q2 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% energy reduction.

All 33,600 luminaires have now been delivered to the Bouygues Energies & Services depot in Kent, all on time and within the contract schedule. CU Phosco are proud to have been involved with this phase of the Kent County Council LED street lighting and highways energy reduction and public lighting improvement project.
