The Supreme Court has dismissed a plea filed by Karnataka’s electricity distribution companies seeking to halt payments linked to invoices worth ₹1,005 crore raised by Adani Power. The discoms had argued that the invoices were wrongful and had been uploaded on a government portal used to track power-purchase transactions and monitor payment arrears. The dismissal is a setback for the Karnataka utilities as the dispute over the payments continues through the electricity-regulatory framework.
The case adds to a broader series of disputes between Adani Power and state-owned distribution companies over tariff adjustments, fuel costs, supplementary invoices and delayed payments. Separately, the Central Electricity Regulatory Commission (CERC) has dealt with Adani Power’s claims involving Karnataka ESCOMs, including a dispute over ₹67.11 crore in withheld energy charges for June and July 2021.
Supreme Court Rejects Karnataka Discoms’ Challenge
The Karnataka electricity distribution companies had approached the Supreme Court over invoices raised by Adani Power. The utilities described the invoices as wrongful and sought relief against their processing through the government’s power-market payment mechanism.
The Supreme Court’s dismissal means the discoms did not obtain the requested intervention from the country’s top court. The immediate dispute involves invoices totaling ₹1,005 crore, making the matter financially significant for both the utilities and the power generator.
Case At A Glance
| Key Detail | Information |
|---|---|
| Amount involved | ₹1,005 crore |
| Petitioner | Karnataka electricity distribution companies |
| Other party | Adani Power |
| Court | Supreme Court of India |
| Dispute | Invoices raised by Adani Power |
| Discoms’ position | Invoices were wrongful |
| Latest development | Supreme Court dismissed the plea |
| Sector | Electricity and power distribution |
The amount involved is substantial for state-owned distribution companies, which already operate under pressure from electricity procurement costs, subsidies, receivables and financial obligations.
What Is The Dispute About?
At the center of the dispute are invoices submitted by Adani Power and uploaded through an official mechanism used for monitoring power-purchase transactions and outstanding payments.
The Karnataka discoms challenged the invoices, arguing that they were not legitimately payable. Adani Power, meanwhile, has been pursuing recovery of amounts it says are due under applicable tariff orders and contractual arrangements.
The Supreme Court’s latest decision does not mean that every underlying billing question has necessarily been resolved in Adani Power’s favor. Rather, it represents the outcome of the specific plea brought before the court and leaves the parties to pursue the appropriate regulatory and legal mechanisms for the underlying claims.
This distinction is important because electricity-payment disputes can involve several layers, including power-purchase agreements, tariff orders, CERC proceedings, appellate decisions and court rulings.
Adani Power And Karnataka Discoms Have Faced Earlier Billing Disputes
The latest dispute is not an isolated disagreement between Adani Power and Karnataka’s electricity utilities.
In a separate proceeding before CERC, Adani Power sought payment of ₹67.11 crore in withheld energy charges for June and July 2021. The claim concerned the Udupi Power Project, a 1,200 MW thermal power station, of which 1,080 MW is supplied to Karnataka distribution licensees under a power purchase agreement dated December 26, 2005.
The dispute in that case arose after Glencore revised the benchmark price used for coal supplied to Adani. The final benchmark price was $107.85 per tonne, compared with a provisional rate of $66.04 per tonne, resulting in a substantial difference in fuel costs.
Earlier Karnataka-Related Adani Power Dispute
| Detail | Figure |
|---|---|
| Udupi Power Project capacity | 1,200 MW |
| Supplied to Karnataka discoms | 1,080 MW |
| Disputed energy charges | ₹67.11 crore |
| Provisional coal benchmark | $66.04/MT |
| Revised benchmark | $107.85/MT |
| Difference | $41.81/MT |
| PPA date | December 26, 2005 |
The earlier case demonstrates why disputes between generators and distribution companies can become complicated: a change in fuel costs can flow through to tariffs and ultimately affect the amount payable by the procuring utility.
How Power Invoices Move Through The System
Electricity billing between generators and discoms is not simply a conventional commercial invoice process. Tariffs can be influenced by regulatory orders, contractual provisions, fuel costs and adjustments determined through subsequent proceedings.

This framework explains why a dispute over an invoice can continue for years. Parties may disagree not only over the amount but also over the tariff methodology, timing of the claim, applicable regulations and whether an earlier order permits recovery.
Why The ₹1,005 Crore Amount Matters
The ₹1,005 crore figure represents a significant financial exposure for Karnataka’s distribution companies.
Discom finances are closely linked to the cost of buying electricity from generators. When procurement costs rise or disputed invoices remain unresolved, utilities can face additional pressure on working capital and cash flows.
For generators, delayed payments create a different problem. Power plants require continuous spending on fuel, operations, maintenance, employee costs and debt servicing. Delayed receivables can therefore increase financing requirements.
Financial Impact Of Payment Disputes
| Stakeholder | Potential Impact |
|---|---|
| Karnataka discoms | Higher payment obligations and cash-flow pressure |
| Adani Power | Delayed realization of receivables |
| Consumers | Potential indirect impact through tariffs |
| Lenders | Greater importance of utility and generator cash flows |
| Power sector | Increased regulatory and legal uncertainty |
The financial consequences can therefore extend beyond the two sides involved in the litigation.
CERC Has Previously Dealt With Adani-Karnataka Claims
CERC’s involvement illustrates the importance of electricity regulators in resolving tariff and payment disputes.
In the separate ₹67.11 crore matter, Adani Power argued that revised fuel costs should be reflected in the energy charges payable by Karnataka ESCOMs. The company said its entitlement arose from the applicable tariff regulations and the terms governing its power supply arrangement.
The Karnataka utilities disputed the claim, including raising concerns about the timing and submission of the revised coal invoice. They also argued that certain amounts had already been paid following reconciliation.
Such cases demonstrate that the final financial liability can depend on detailed examination of contracts, tariff regulations and previous regulatory orders.
Supreme Court’s Role In Power-Sector Disputes
The Supreme Court has previously dealt with major disputes involving Adani Power and electricity distribution companies.
In 2023, the court upheld compensation for Adani Power Maharashtra under the “change in law” provisions of a power-purchase agreement and criticized state distribution companies for taking a position contrary to the Union government’s position on the issue.
The court has also upheld the principle that distribution companies can be liable for late-payment surcharges when they delay payments that are contractually and regulatorily due. CERC orders have subsequently referred to that Supreme Court precedent in electricity-sector disputes.
These precedents are relevant because payment disputes in the power sector often involve not just the principal invoice but also questions around interest and late-payment surcharges.
Implications For Karnataka’s Power Sector
The latest Supreme Court decision comes as Karnataka continues to manage rising electricity demand and a diverse procurement portfolio.
The state relies on a mix of thermal, renewable and other sources of electricity. Distribution companies must balance the need to secure adequate power with the need to manage procurement costs and maintain financial stability.
Large contractual disputes can complicate that balancing act.
For power generators, however, predictable payment mechanisms are equally important. Thermal power projects involve substantial fixed costs and capital investments, making timely recovery of approved tariffs critical to their financial viability.
The Broader Issue Of Discom Finances
Discom finances remain one of the structural issues facing India’s electricity sector.
Distribution companies collect revenue from consumers but must also pay generators, transmission companies and other suppliers. Delays in collections, subsidies and regulatory adjustments can affect their ability to make timely payments.
When disputes over invoices arise, the resulting litigation can add another layer of uncertainty.

For generators, the risk is delayed cash realization. For discoms, the risk is that unresolved claims eventually become larger liabilities because of interest or late-payment charges.
What Happens Next?
The Supreme Court’s dismissal removes the specific relief sought by the Karnataka discoms in the latest plea, but the wider financial and regulatory issues surrounding the invoices can continue through the appropriate proceedings.
The exact implications will depend on the nature of the underlying invoices, the applicable tariff and contractual provisions, and any other proceedings involving the parties.
The development is therefore best viewed as another stage in a broader dispute between a major private power generator and state distribution utilities rather than as the end of every disagreement between them.
The Bigger Picture
The Supreme Court’s dismissal of the Karnataka discoms’ plea over ₹1,005 crore in Adani Power invoices highlights the financial and legal complexity of India’s electricity market. Generators need timely recovery of approved costs and tariffs to maintain financial stability, while discoms must ensure that only legitimate contractual and regulatory claims are passed through their accounts.
The case also illustrates why power-sector disputes can persist across multiple regulatory and judicial forums. Earlier Adani Power-Karnataka proceedings have involved fuel-price revisions, tariff calculations and delayed payments, showing how a single power-purchase arrangement can generate complex claims when underlying costs or regulatory determinations change.
Looking Ahead
The immediate focus will be on how the ₹1,005 crore invoice dispute progresses after the Supreme Court’s dismissal and whether the parties pursue further remedies through the relevant electricity-regulatory mechanisms. The financial impact on Karnataka’s discoms will depend on the final treatment of the invoices and any related claims for interest or other charges.
For India’s power sector, the case reinforces the importance of predictable payment and dispute-resolution mechanisms between generators and distribution companies. As electricity demand grows and utilities sign increasingly large procurement contracts, resolving billing disagreements efficiently will be important for protecting both discom finances and the financial health of power generators.
