Presenting a grim picture of the financial health of the Tamil Nadu Power Distribution Corporation Limited (TNPDCL), the White Paper on the finances of the State government has stated the power utility faces a “persistent monthly structural cash shortfall,” which is independent of the Average Cost of Supply(ACS)-Average Revenue Realised (ARR) position. A monthly shortfall of ₹2,500 crore translates to an annual liquidity gap of about ₹30,000 crore, financed through a combination of short-term borrowings, delayed payments to power purchase counterparties, and deferred capital expenditure. The shortfall arises in view of the monthly payment obligations for power purchase, debt service and operations. The situation is despite the TNPDCL receiving tariff subsidy and loss-funding grant transfers., according to the document. TNPDCL is one of the entities formed after the abolition of the Tamil Nadu Generation and Distribution Company (TANGEDCO) in 2024.

The other firms are the Tamil Nadu Power Generation Corporation Limited (TNPGCL) and the Tamil Nadu Green Energy Corporation Limited (TNGECL). The three companies, along with Tamil Nadu Transmission Corporation (TANTRANSCO), form, what is popularly called, the TNEB (Tamil Nadu Electricity Board) group. Describing the ACS-ARR gap as the “fundamental operating driver” of the TANGEDCO’s losses, the White Paper, released on Tuesday, recalled for seven consecutive years up to 2021-22, power tariff was not revised with the gap rising to ₹1.58 per unit. The introduction of Multi-Year Tariff (MYT) in 2022-23, linked annually to the Consumer Price Index, provided “partial correction.” The gap had since narrowed down “sharply,” reaching ₹-0.05 per unit in 2024-25 and turning marginally positive (₹0.04/unit) on a provisional basis in 2025-26. However, this was “not owing to the operational efficiency or full recovery of the cost of supply from consumers.

On the contrary, despite tariff hikes, there has been little structural improvement in the finances,” the document stated, attributing the declining gap to the “huge” financial support of the State government to fund the revenue loss of the TNPDCL. To give an illustration, the annual support given by the government to the TNEB group was ₹20,996 crore during 2021-22 and this went up to ₹ 33, 478 crore in 2025-26, a “59.45% increase in five years.” A total of ₹1,45,185 crore was provided to the group in the last five years. The White Paper cautioned electricity consumers the situation “is going to be further compounded” on account of the Supreme Court’s order on regulatory assets with a “fresh large-scale financial obligation.” While an appeal had been filed, the judicial verdict’s implication for Tamil Nadu was that the consumers or the State government, through subsidies, should absorb the regulatory assets of ₹59,000 crore, which had been incurred by the power utilities but not recovered along with the carrying cost either through tariff or by grant.
