Summary of the Action<br />
Street lighting in <strong>Karak</strong> Municipality consumes 5,872 MWh of electricity per year, which represents an overall annual cost of<br />
684,694 JOD/yr. Various types of lamps are used for street lighting, more specifically: High Pressure Sodium and Mercury Vapor.<br />
According to the Municipality Staff, the entire service requires around 25,000 lamps and is controlled by timers. An analysis of<br />
the street lighting system’s current situation is presented in the table below.<br />
Type Quantity Power (Watts) Electricity Consumption (MWh)<br />
Mercury Vapor Lamps 17,500 145 3,239<br />
High Pressure Sodium Lamps 7,500 275 2,633<br />
For the calculation of the electricity consumption in the above table, the same operational hours for both types of lamps have<br />
been considered.<br />
The Municipality wants to launch a process to change all the lamps in the city and improve the overall performance of the street<br />
lighting system.The recommendation is to replace:<br />
<br />
the Mercury Vapor Lamps with 50W LED Lamps (saving 65.5% of energy consumption) and<br />
<br />
the High Pressurre Sodium Lamps with 90W LED Lamps (saving 67.3% of energy consumption).<br />
Consequently, it derives that 3,894 MWh will be saved annualy which leads in 453,894 JOD (594,719€) annual cost saving, taking<br />
into consideration that 1 KWh of electricity costs 0,1166 JOD and using the conversion rate 1 JOD=1,31€. The specific lamp sizes<br />
were selected in order to ensure the proper light quality on the road network.<br />
The costs of the purchase are:<br />
<br />
120JOD per lamp for the 17,500 LED lamps of 50W, namely 2.1 million JOD and<br />
<br />
170 JOD per lamp for the 7,500 LED lamps of 90W, thus 1.275 million JOD.<br />
It derives that the total cost for the equipment is 3,375,000 JOD (4,421,250€). The human resources cost for the removal of the<br />
old lamps and placement of the new ones will be covered by the contractor, including conducting awareness sessions with the<br />
community which will cost an additional amount of around 3,000 JOD.<br />
In addition, assuming the life expectancy of the lamps that equals 14 years, for the current operational hours, the Net Present<br />
Value is positive and high. For the calculation of the NVP, i has been considered equal to 8%.<br />
