TPCL tops service ratings but ranks 40th overall in DISCOM index

The Tata Power Company Limited (TPCL) has received the highest consumer service rating among distribution utilities in India, yet ranks 40th overall in combined performance rankings, highlighting a structural issue in the evaluation framework.

In the fifth edition of the Consumer Service Rating of DISCOMs (CSRD), published by REC Limited (REC), TPCL scored 97.1 out of 100 and secured an A+ grade. It ranked first among 66 utilities across all categories, with a clear lead on consumer service metrics.

Divergence between service and overall ranking

In contrast, the Distribution Utilities Ranking (DUR) for FY 2024–25 places TPCL at 40th overall and 9th among 10 urban utilities, with a combined score of 63.1. Despite this, TPCL recorded strong scores across several operational parameters, including 100 in Resource Adequacy, 100 in Communicable System Metering, 92 in Demand Side Response (DSR), and 90 in Renewable Purchase Obligation (RPO) achievement.

The gap arises from TPCL’s non-participation in the 14th edition of Power Finance Corporation’s (PFC) Annual Integrated Rating (IR) exercise, which carries a 35% weight in the DUR methodology. Non-participation results in a zero score for this component, significantly lowering the overall ranking. The DUR report notes that participation in the IR assessment could have placed TPCL among top-ranked utilities.

Framework design and implications

The IR framework evaluates financial sustainability indicators such as Aggregate Cost of Supply–Aggregate Revenue Realised (ACS–ARR) gap, debt service coverage, billing and collection efficiency, receivable days, and corporate governance practices.

The current DUR design allows utilities to opt out of sub-components, with the only consequence being a zero score for that segment. For utilities with strong operational performance, this can create a divergence between service quality and overall ranking outcomes.

The divergence in TPCL’s case points to a broader design consideration for the Ministry of Power (MoP) and REC. Whether participation in the IR exercise should remain optional or be made a qualifying requirement for inclusion in the DUR framework remains an open question.

Taken together, the CSRD and DUR frameworks provide detailed insights into distribution utility performance. The difference in TPCL’s rankings reflects both its operational strengths and the impact of methodological choices within the evaluation system.
