Kilkenny County Council - LED Street Lights Retrofit Project

Kilkenny : Highways Electrical



Kilkenny County Council (KCC) appointed Enerveo to carry out design, supply, installation, testing, commissioning and Project Supervisor Construction Stage (PSCS) / Project Supervisor Design Progress (PSDP) roles on their streetlight LED Retrofit Pilot Project.

KCC, in partnership with Carlow-Kilkenny Energy Agency (CKEA), had prepared an Energy Performance Contract (EPC) designed to guarantee nancial savings and improve technical performance. As part of the contract, KCC and CKEA identifed a number of declassifed road networks and other areas of inefficient lighting systems in Kilkenny for improvement. With the Sustainable Energy Authority of Ireland (SEAI) and Transport Infrastructure Ireland (TII) on board, KCC engaged with Enerveo through a tender process. Strict deadlines were in place, and Enerveo had just 3 months to complete the EPC.

This sizeable task involved the improvement of 1,344 lights across 29 locations with each location requiring an individual lighting design report, energy calculations and a life-cycle cost analysis as well as the supply and installation of c500 interface units and brackets. The lighting designs proposed by Enerveo were focused on installing more effecient lanterns and maximising the optics of the LEDs due to be installed. Programming and scheduling of the LED upgrade works was carried in conjunction with Kilkenny City and county and each location covered a range of residential and national route lighting. Trac management consisted of “Stop/Go” signage as well as single and mobile lane closures. A Trac Management plan was required by KCC’s Trac Department.


The project was successful and as a result, all locations identified in County Kilkenny now operate utilising the latest in LED technology. It has also been one of the largest retrofit projects in the country to date. The project has enabled KCC to ensure sustainability and energy efficiency are key as they move forward with future projects.
