This paper proposes an index-based analytical framework to quantify the quality of electricity supplied in a specific location. Four quality defining indicators: day and night supply hours, evening supply hours, normal voltage hours, and frequency of power cut were selected to form a composite quality index. The study consists of ten sample rural villages and four capital cities across four Indian provinces (Andhra Pradesh, Madhya Pradesh, Uttar Pradesh, Uttarakhand). The average value of the electricity quality index for rural locations was 0.53, and for province capital locations, it was 0.93 for the year 2018. This reveals that electricity quality in rural areas needs significant improvement. The average electricity quality index for both rural and capital locations was relatively better in Madhya Pradesh. This generic analytical framework can be applied to monitor the electricity quality over time in a village, city, district, or province depending upon the data availability.
