print mail ENERGY EFFICIENCY IN STREET LIGHTING

The project activity consists of improving the existing street lighting system in nine municipalities in Montenegro, with approximately 300.000 inhabitants, by means of more efficient lighting technologies. According to the EE Strategy, by providing a good selection of the lightings and automatic lighting regulation, it is possible to obtain energy savings of 20 - 25% in this field.

At present, there is a wide usage of obsolete bulbs made with mercury. They consume more electricity for the same magnitude of light and their lifetime period is one year, which is three times less compared to the bulbs made with sodium.
Therefore, the project activity would consist of replacing more than 11.450 bulbs made with mercury by the modern ones made with sodium. Based on this, the energy efficiency would be increased, while electricity consumption and maintenance costs would be decreased, due to a longer lifetime period of high pressure sodium bulbs. The result of the project activity would be the electricity savings in the amount of 4.300 MWh per year, and the GHG emissions reductions.
Energy efficient lighting projects do not contribute significantly to the reduction of carbon emissions. However, when packaged as part of a bigger project, they can make a significant contribution to the reduction of CO2 emissions. Maintenance and proper care (during monitoring periods) should be taken to ensure the ongoing use of the new lighting system.
This project could be a basis for defining and predicting the possibilities for development of a relevant larger project, for example lighting efficiency improvement in street lighting in the entire country.

Applied methodology

The calculated emissions reductions are under the maximum limits of the small scale methodology “Demand-side energy efficiency programmes for specific technologies” – II.C, which could be applied in this project.

GHG offset

This project activity is considered as bundling one for nine municipalities. It is estimated that the project has a capacity to avoid emission and over 24.000 tCO2eq for the period 2008-2018.

Sustainability

The project will improve the power availability and quality of light in the local area. In addition, the project aims at contributing to an economically, environmentally and socially sustainable development of the region.

Estimated investment cost

Investments:
  • for material: 750.000 €
  • for replacement works: 130.000 €
SUM of investments: 880.000 €
Annual savings:
  • savings due to the reduction of electricity consumption: 253.300 €/year
  • savings due to longer lifetime period of bulbs (works and material): 60.400 €/year
SUM of annual savings: 313.700 €
In first two months of year 2007, price of electricity was increased on the level of 0,06 €/kWh due to larger electricity imports. Therefore, estimated payback period is 3 years.
