Demand-side management(DSM) is used to describe the actions of a utility, beyond the customer's meter, with the objective of altering the end-use of electricity whether it be to increase demand, decrease it, shift it between high and low peak periods, or manage it when there are intermittent load demands - in the overall interests of reducing utility costs. In other words DSM is the implementation of those measures that help the customers to use electricity more efficiently and in doing so reduces the customer utility costs. DSM can be achieved through improving the efficiency of various end-uses through better housekeeping ,correcting energy leakages, system conversion losses, and using renewable energy(RE) systems. In the past few decades the renewable energy sources have received grater interest and considerable attention has been given to efficient energy conversion and utilization techniques. Due to seasonal & periodic variations a single renewable energy source cannot provide continuous supply. In this case the Hybrid system with combination of two or more Resources can provide a better efficiency with considerable optimal cost. Present paper discusses a case study of an Urban restaurant. As a first step ,walkthrough Energy Audit has been carried out and using Dialus package Uplamping technique has been proposed.In the next step ,HOMER ‘NRELs simulation Tool has been used to model Hybrid RE system with diesel generator as the backup. In the last step, based on the model developed in the HOMER, Return on investment(ROI) has been calculated with & without subsidy. The proposed ROI model has shown 20 % optimal contribution of Hybird RE for the problem considered in the present study.
