Eng.(Hons) at University of Moratuwa, M.Sc. in Electrical Installations at University of Moratuwa, AMIE (Sri Lanka), The telecommunication industry in Sri Lanka is showing fast growth and expands services to their customers, especially during past decades, by increasing number of service providers with much competitive Tariffs. The main challenge of the service provider is to sustain with the competitive Tariff reductions and advancement of their services to customer doorstep demanding by the industry. Not like in other industry, the telecom customer is having the freedom to select any service provider by own decision without facing any monopoly or other influence by the industry. This automatically creates the industry to reduce their OPEX & CAPEX continually. The CAPEX is always increasing and the reduction possibility exists only with OPEX in the telecom industry. Electricity contributes to the major portion of OPEX of remote telecom site operations. The electricity by means of Diesel Generator (DG) operation or Commercial supply (CEB/ LECO) is always a difficult facility in remotely operated telecommunication base stations. This is due to the nature of the location of the selected site and the quality of the nearest/ rural commercial supply. Due to this, the site needs to run with the DG in most of the period of the day or face with service outages due to interruptions of the electricity with huge OPEX and unexpected losses in income. The main objective of this research project is to develop a system for automatic voltage regulation at remote telecommunication sites with customized features. The outcomes of this research will be a remarkable development in the telecom industry. We also supposed to share this knowledge with all the interesting parties to extend the benefits not only to the telecom service providers, but also to the customers by means of lowest tariffs
