Result of road lighting energy saving project implementation through the use of public private partnership scheme

This paper is to summarize the result of road lighting energy saving project carried out by Provincial Electricity Authority (PEA) through the use of Public Private Partnership (PPP) scheme. Energy saving using power reducing equipments for high pressure sodium (HPS) road lighting has been installed to alleviate the use. The result has been satisfactory with saving energy of about 25-30%. Investment cost leads to a large financing burden to PEA. Monitoring, maintenance and management systems have been strongly needed. Large number of road lighting is significant barrier to extend the project throughout the country. PPP scheme associated with Energy Service Company (ESCO) is a new approach to cope with these difficulties. Universities were adopted in dealing with this PPP project. Investment cost, financial charge and other expense were provided by the universities. Amount of actually saved energy stream would be paid to those universities until its investment costs have been fully recovered along the project contracting period. The result shows that the implementing scheme tends to be a sustainable project development. Moreover, the basis of financial scheme is able to be applied to other energy saving projects.
