Romania: City of Rovinari
Rovinari is a coal mining town in Gorj County, Oltenia, Romania. The city is located 25 km southwest of Targu Jiu and is connected with rest of the country through the national road DN 66 (part of the European route E79). It has an electric railway which connects Targu Jiu ‐ Rovinari ‐Turceni ‐ Filiaşi and Craiova.
The project consists of installing new lamps on existing light-poles in the city.
The tender documentation was based on research carried out in regards to the reduction of energy consumption and increasing the energy efficiency of the lighting system. The lamps utilized were sodium‐vapour lamps (high‐pressure sodium lamps ‐ HPS). The HPS lamp is the most common lamp for street lighting on the planet. The lamp is better than the LPS lamp (low‐pressure sodium) since it has more acceptable colour with a acceptable efficiency. The improved colour rendering comes with a bit of sacrifice; it is less efficient than the LPS.
- Good efficiency (lumens per watt)
- Smaller size than LPS or fluorescent, the HPS fits into many fixture types
- Can be retrofitted into older Mercury Vapour fixtures
- Longer bulb life than LPS lamps
- The installed capacity of the new lighting system is about 61 kW
Total budget: 125,000 USD
- Municipal investments 20 %
- Financial institutions / banks 80 %
The project contributes to fighting climate change by achieving savings in electric consumption. The new lamps generate savings of up to 35 %.
