The Energy Efficiency Project for Public Lighting developed and implemented by HEP ESCO in the city of Karlovac was worth 8.2 million kuna. The implementation of the Project brings the city of Karlovac energy savings of as much as 686 thousand kuna a year.
The Project was carried out on ESCO model in which HEP ESCO developed and implemented the Project and financed its energy efficiency portion amounting to 5.5 million kuna. The remaining amount of 2.7 million kuna was secured by the city of Karlovac.
The Project included replacement of 2,100 old mercury light bulbs with new, more efficient sodium light bulbs. Light flow controls which additionally save energy in late night hours were also installed.
