Electricity demand is the most important aspect in India. The research here was carried out analyze the pattern of electricity consumption in Mumbai Metropolitan Region (MMR). 51 households were surveyed which were the main area of study. The findings showed the average consumption of electricity in MMR region was 399 units or kWh per month. The research also shows that the replacement of all the appliances with the best energy saving technologies available in the market would reduce the average consumption by 46%. A Household Energy Performance Index (HEPI) was formulated which would compare the electricity consumption of households of equal stature. The index was formulated considering 2 important factors of energy consumption i.e. per capita per month consumption and number of people living in the house. The findings of HEPI showed that it can be related to the area of the household and is directly proportional. The area of the houses can then be used to limit the power consumption. The area of more than 1000sq.ft. can have HEPI of maximum 0.5. The area of the house between 500-1000 sq.ft. should be up to 0.45 and that of houses less than 500sq.ft should have maximum HEPI of 0.4. Classifying the findings of HEPI and area of houses in the 3 main areas of MMR i.e. The Mumbai area, Thane and Navi Mumbai it was found that the HEPI was almost equal in spite of great the variation in area of houses in all the 3 areas.
