Improving energy efficiency and reducing greenhouse gases is a central issue of the Europe 2020 strategy. Today enormous electric energy is consumed by the street lighting. Much of it could be saved through suitable energy-conservation measures (ECMs). The energy audit of the street lighting system in the Pravets municipality was carried out in compliance with the legislation in force in the EU and Bulgaria. Data about the present state of street lighting and electricity consumption for a period of 3 years were gathered and analysed. The baseline electricity consumption was defined. Classification of streets was done and the light class of the different categories streets was determined. The potential for energy savings was identified and a package of ECMs was developed. The annual electricity savings are 680 MWh (or 57,441 €/y) and the annual CO2 emissions savings are 557,640 t. The investment for implementation of the envisaged ECMs is 414,840 €. The expected electricity savings compared to the baseline are 75%.
