Purpose: This paper evaluates the operational efficiency of distribution utilities of Haryana’s power sector during 2013-14 to 2023-24, following the prolonged sectoral reforms.

Methodology: The study is based on secondary data from the publications of Power Finance Corporation and the Haryana Electricity Regulatory Commission, employing year-on-year growth rate, compounded annual growth rate, exponential growth rate, and Pearson correlation techniques to assess billing, efficiency, collection efficiency, AT&C losses and consumer growth.

Findings: The analysis shows uninterrupted growth in the consumer base, improvement in billing productivity, virtually complete revenue collection, and a remarkable decline in AT&C losses over the study period. Correlation results point to strong associations among operational indicators, indicating that efficiency gains tend to coexist with lower AT&C losses.

Implications: The study highlights improved administrative processes, technological advancements, and better system discipline and the positive trends indicate a trajectory towards deeper operational reforms, improved service quality and lasting financial sustainability.
