DISCOMs: Turning the Tide in India's Electricity Sector

Legacy of losses: India’s power distribution utilities (DISCOMs) have historically struggled with persistent losses due to a combination of operational inefficiencies, high Aggregate Technical and Commercial (AT&C) losses, and the gap between the Average Cost of Supply (ACS) and Average Revenue Realised (ARR). Between 2020-21 and 2024-25, accumulated losses of DISCOMs rose from ₹5.5 lakh crore to ₹6.47 lakh crore, with debt reaching ₹7.26 lakh crore.

Structural and policy issues: Non-cost-reflective tariffs, delayed State subsidy payments, and poor financial discipline exacerbated the problem. The legacy of State Electricity Boards (SEBs), which were mandated to make profits under Section 59 of the Electricity (Supply) Act, 1948 but largely operated in the red, has continued in the DISCOM era.

Operational inefficiencies: Line losses, inadequate metering, and limited segregation of agricultural and non-agricultural feeders have further worsened financial health. These structural challenges created an environment where utilities were reliant on government interventions and subsidies to remain operational.

Significance of turnaround: The turnaround of DISCOMs, reflected in a positive Profit After Tax (PAT) of ₹2,701 crore in 2024-25 and reduction in AT&C losses from 22.62% to 15.04%, signals a shift from chronic inefficiency to operational sustainability. The ACS-ARR gap narrowing from 0.78 paise/unit to 0.06 paise/unit indicates that utilities are moving toward cost-reflective pricing.

Contributing factors: Key measures driving improvement include the implementation of the Revamped Distribution Sector Scheme (RDSS), amendments to Electricity Rules, and the Late Payment Surcharge Rules. These interventions enabled timely payment of dues, structured repayment of legacy liabilities, and enhanced operational accountability.

Government support: While improved performance is commendable, the role of State subsidies and loss takeover remains significant. For example, TNPDCL in Tamil Nadu recorded a profit of ₹2,073 crore after receiving ₹15,772 crore in tariff subsidies and ₹16,107 crore for loss takeover. This highlights that structural reforms must be complemented by financial support to achieve tangible results.

Revamped Distribution Sector Scheme (RDSS): RDSS aims to improve the quality, reliability, and financial sustainability of power distribution. By linking fund releases to specific operational and efficiency measures, RDSS incentivises utilities to adopt best practices, reduce AT&C losses, and enhance cost recovery.

Late Payment Surcharge Rules: These rules allow DISCOMs to clear legacy dues through a maximum of 48 equated monthly instalments (EMIs), which has enabled utilities in 13 States and Union Territories to pay ₹1,31,942 crore between June 2022 and December 2025. By structuring repayment and preventing the accumulation of arrears, the Rules restore credibility with generators and financial institutions.

Outcome: The combined effect of these measures has been improved cash flows, reduced financial stress, and greater adherence to timely payments. Current dues are largely being met on schedule, reflecting enhanced fiscal discipline and operational transparency in the sector.

Dependency on government support: Much of the reported profitability is contingent upon tariff subsidies and takeover of losses by State governments. For instance, TNPDCL and JDVVNL recorded profits only after receiving large subsidies, highlighting that intrinsic operational efficiency is still incomplete.

Future cost pressures: Upcoming employee pay revisions, rising input costs, and potential increase in AT&C losses can threaten the sustainability of the current surplus. Without continuous policy interventions and operational reforms, DISCOMs could revert to revenue deficits.

Structural and political challenges: The political temptation to offer free or subsidised electricity to certain consumer categories, especially in agriculture, can undermine cost recovery. Without stricter tariff rationalisation and adherence to financially sustainable policies, the current gains may remain transient.

Feeder segregation: Separating agricultural feeders from non-agricultural ones allows DISCOMs to meter consumption accurately, reduce AT&C losses, and implement targeted subsidies. States like Rajasthan, Andhra Pradesh, Gujarat, Karnataka, and Maharashtra have made progress in this area. Extending such measures to other States, e.g., Tamil Nadu, can significantly improve transparency and financial viability.

Renewable energy integration: Promoting solar pumps and other decentralized renewable energy applications can reduce DISCOMs’ reliance on costly grid power for agricultural purposes. As highlighted by NITI Aayog, this not only lowers procurement costs but also enhances grid stability and energy efficiency.

Challenges and considerations: While these measures offer potential, they require sustained political will, investment in infrastructure, and careful planning to avoid social inequities. Free electricity schemes, if not targeted, may disproportionately benefit wealthier sections, negating efficiency gains.

Tamil Nadu Power Distribution Corporation Limited (TNPDCL): TNPDCL reported a profit of ₹2,073 crore in 2024-25, largely after receiving ₹15,772 crore in tariff subsidies and ₹16,107 crore for takeover of losses. Without these interventions, the utility would have recorded a loss of ₹14,034 crore.

Jodhpur Vidyut Vitran Nigam Limited (JDVVNL), Rajasthan: JDVVNL improved its financial performance to a profit of ₹92 crore after receiving ₹11,625 crore in tariff subsidies and ₹2,540 crore for loss takeover. This demonstrates that targeted financial support, combined with operational improvements, can facilitate a turnaround.

Implication: These examples underscore the importance of government intervention in stabilising DISCOM finances while structural reforms, such as AT&C loss reduction and feeder segregation, are implemented concurrently.

Operational reforms: Sustained reduction of AT&C losses through metering, feeder segregation, and automation is crucial. Accurate measurement of electricity consumption and cost-reflective tariffs can improve revenue collection and reduce dependency on subsidies.

Policy measures: Rationalising tariffs, promoting prepaid and digital payment systems, and introducing performance-linked incentives under schemes like RDSS can enhance efficiency. Encouraging renewable energy adoption, particularly solar pumps in agriculture, reduces power procurement costs and strengthens DISCOMs’ financial base.

Governance and accountability: Strengthening institutional capacity, establishing clear accountability frameworks, and insulating DISCOMs from political interference in tariff setting will ensure long-term viability. Public-private partnerships, technology adoption, and regulatory oversight are also essential components of a sustainable distribution sector.

Conclusion: A combination of operational excellence, policy discipline, technological adoption, and targeted subsidies will be necessary to transition DISCOMs from temporary financial gains to enduring sustainability.
