Situation before the contract and client requirements
- Nova Crnja is a municipality in Serbia’s northern province of Vojvodina, with 12,700 inhabitants.
- Its public lighting infrastructure is outdated and the municipality published a tender for a public private partnership to renovate lighting in the towns under its jurisdiction.
- Resalta won the tender with its technical partner.
Resalta has replaced 1,321 obsolete and inefficient luminaires with LED luminaires. The new energy efficient Philips luminaires installed have reduced the lighting capacity by 144 kW, down to 24 kW. They were carefully selected following photometric measurements to fill all the requirements of towns within the municipality.
Resalta has also replaced the obsolete systems for switching public lighting on and off in all 50 substations in the municipality, with an automated system regulated by an astronomic clock adjusted for the conditions in Nova Crnja, enabling optimal energy savings as well as the required 4,000 operating hours per year.
