The City of Kruševac in southern Serbia has signed a public-private partnership (PPP) with GGE, a regional energy efficiency services provider, for a complete renovation of public lighting systems in 99 of the towns that fall within its administrative area. Besides being the largest public lighting PPP in the Balkans by number of light bulbs and luminaires to be replaced, this project is also the largest energy efficiency PPP in Serbia to date.
Signed on 21.09.2017 between the Mayor of Kruševac and GGE, the private partner, the PPP provides measures for the replacement of 12,545 old inefficient luminaires with 12,545 Phillips and Schreder LED luminaires. GGE will also replace the obsolete systems for switching public lighting on and off in all 330 substations in the municipality. The new system will be automated and regulated by an astronomic clock adjusted for the conditions in Kruševac, enabling optimal energy savings as well as the required 4,000 operating hours per year.
The equipment was carefully selected following photometric measurements to fill all the requirements of the city and its surrounding towns. Switching to LED will reduce the total wattage of installed light from 1,664 kW to 356 kW, which will result in financial savings of almost 85% for the City of Kruševac once the private partner is paid off. The contract duration is set at 12 years, but GGE will provide guarantees for the equipment installed for an additional 3 years.
