Case Study

Expansion of efficient public lighting in Bucharest

Luxten Lighting Company is the public operator of the Bucharest public lighting system since 1997.  The Company planned to modernize the public lighting systems in the second part of the Dorobanti area, Bucharest by replacing the existing lighting poles and luminaires with LED efficient bulbs.

The company addressed Municipal Financing Facility for Energy Efficiency (MFFEE) and its participating bank BRD Société Générale (BRD) for financing this project.
 
The MFFEE team supported the company with analysis of the proposed technology, potential of energy savings and financial-technical parameters of the project.
 
The €4.03 million investment allowed to reduce the public lighting consumption by 118  MWh per year, which is equal to 38 per cent of initial situation.
 
The investment project consisted of the following: 556 LED bulbs 49 W; 122 LED bulbs 77 W; 80 LED bulbs 25 W; 45 LED bulbs 116 W; Telemetering system.
 
Among the main advantages of the proposed measures are:
  • Long life cycle of the sources: LED 50,000 hours as compared to 18,000 hours of existing units
  • Low energy consumption of LED: 49W÷100W as compared to existing units' 81W÷425W;
  • Significant savings on maintenance due to the long life of LEDs;
  • The quality of light produced and colour rendering mode (CCT: 5000 - 7000K, CRI > 70) are much improved compared to conventional sources. This, in addition to aesthetic benefits, is important for the community, for the safety of citizens and motorists, as well as for the possible quality video footage cameras, thus decreasing vandalism and ensuring road traffic and pedestrian safety;
  • LED bulbs of low and high power are completely environmental friendly (certified RoHS - restriction of use of certain hazardous substances in electrical and electronic equipment);
  • Lower CO2 emissions through reduced electricity consumption;
  • Safe functioning and operation of economic and energy efficient public lighting infrastructure;
  • Control and monitoring of consumption.
 
The municipality could feel the result of the investment immediately thanks to reduced costs for street lighting services.
 
This way, the EBRD through MFFEE supports sustainable financing and implementation of energy efficiency projects in the municipal sector. Together, the residential, private, and public sectors can make a change in the energy consumption patterns and environmental protection.
