Talwandi Sabo Power Limited (TSPL), a subsidiary of Vedanta Limited, has been ordered to pay approximately ₹127 crore plus applicable late payment surcharge after the Supreme Court of India upheld a penalty for alleged misdeclaration of power availability in January 2017. The ruling, delivered on 20 May 2025, came in civil appeals filed by Punjab State Power Corporation Limited (PSPCL) and Punjab State Load Despatch Centre (PSLDC).
What the Supreme Court Ruled
The apex court set aside the 18 March 2025 judgment of the Appellate Tribunal for Electricity (APTEL) and restored the earlier order passed by the Punjab State Electricity Regulatory Commission (PSERC). The bench allowed the appeals preferred by PSPCL, effectively reinstating the penalty that APTEL had previously overturned.
The penalty relates to TSPL's alleged misdeclaration of power availability under the provisions of the Grid Code for January 2017 — an incident now nearly eight years old that has wound its way through multiple layers of regulatory and judicial review.
Vedanta's Disclosure to Stock Exchanges
Vedanta Limited disclosed the development to stock exchanges on Thursday, 21 May, through a regulatory filing signed by Prerna Halwasiya, Company Secretary and Compliance Officer of Vedanta Limited. The communication from TSPL itself was signed by Bhagya Hasija, Company Secretary and Compliance Officer of Talwandi Sabo Power Limited.
In the filing, Vedanta stated: 'The Supreme Court of India passed in Civil Appeal filed by PSPCL and PSLDC, has set aside the judgment dated 18.03.2025 passed by the Appellate Tribunal for Electricity (APTEL), restored the order passed by the Punjab State Electricity Regulatory Commission (PSERC), and allowed the appeals preferred by PSPCL.'
TSPL's Ongoing Listing Process
The judgment arrives at a sensitive moment for TSPL. According to the regulatory filing, TSPL's equity shares are currently in the process of being listed on the Bombay Stock Exchange (BSE) and the National Stock Exchange (NSE), following the demerger of the merchant power undertaking from Vedanta Limited. The ₹127 crore liability, along with the surcharge, will now need to be factored into TSPL's financial disclosures ahead of its market debut.
Background and Context
The case traces back to a Grid Code violation allegation from January 2017, when TSPL was accused of misrepresenting its power availability to the grid operator — a practice that can distort dispatch decisions and impose costs on state utilities. PSERC had originally imposed the penalty; APTEL reversed it in March 2025, only for the Supreme Court to restore the original order within weeks.
This is the latest in a series of regulatory and legal challenges facing power producers in Punjab, where disputes between independent power producers and state utilities over scheduling, availability declarations, and payment obligations have been a recurring friction point. With TSPL's listing now underway, the resolution of this long-running case brings at least one major liability into the open.
Point of View
The timing is particularly awkward: a ₹127 crore liability surfacing mid-listing is the kind of disclosure that prospective investors will scrutinise closely. More broadly, the case reflects a pattern of protracted disputes between Punjab's state utilities and independent power producers, where billing and availability-declaration disagreements routinely escalate to the highest court. Until the regulatory framework for Grid Code penalties is codified with greater precision, similar multi-year litigation cycles are likely to recur across the sector.
