Coal surcharges, forest taxes, railway hikes—who pays when the government adds new costs after a power deal is signed?

In a courtroom in April 2023, the bench was stacked with files, each one a decade of disputes bound in legal thread. On one side stood power generators who had signed long-term contracts years earlier. On the other stood state electricity distribution companies—the DISCOMs—who bought their power. At the centre of every single dispute was the same question: when a government agency imposes a new tax or levy after a power purchase agreement (PPA—the long-term contract that fixes the price of electricity) is signed, who bears the cost?

The Supreme Court's answer was emphatic. The generator pays nothing extra. The DISCOM pays everything—including interest.

When the coal train got more expensive

Here is how the story begins. Multiple thermal power companies built plants and signed long-term PPAs with state DISCOMs. These were competitively bid contracts, meaning the generators quoted a fixed tariff and won the right to supply power at that rate for years—sometimes decades. The price was locked. The risk of future cost increases was supposed to be allocated between the parties.

Then the government moved.

The Railway Board raised freight charges—a single-page notification, its ink barely dry, that sent costs rippling across every coal-fired plant in the country. New environmental rules changed coal quality requirements. Coal India imposed additional levies. State governments introduced forest taxes and infrastructure cesses. The central government altered coal distribution policies, reducing the assured supply of coal that generators had counted on. Each of these changes, imposed after the PPAs were signed, pushed up the cost of producing electricity.

The generators went to the electricity regulators—the Central Electricity Regulatory Commission (CERC) and various State Electricity Regulatory Commissions (SERCs). Their argument was simple: the PPA had a clause called "Change in Law" that was meant to protect them from exactly this kind of post-contract cost imposition. They wanted compensation.

The regulatory seesaw

The regulators partly agreed. They granted some claims and rejected others. Both sides were unhappy. The generators appealed to the Appellate Tribunal for Electricity (APTEL), arguing that more costs should have been covered. The DISCOMs cross-appealed, arguing that fewer costs should have been covered. APTEL partly allowed the generators' appeals, granting additional Change in Law components including something called "carrying cost"—essentially, interest on the delayed compensation.

Both sides then landed at the Supreme Court. The DISCOMs argued that many of these post-contract levies were not "Change in Law" events at all. The generators argued that the compensation should have been even broader. The Court had to resolve a batch of cross-appeals spanning multiple power plants, multiple regulators, and multiple types of government-imposed charges.

What counts as a 'Change in Law'

The core legal question was deceptively simple. The PPAs defined "Change in Law" as any change in any law, rule, regulation, notification, or order by a government instrumentality after a specified cut-off date. The DISCOMs argued that some of the charges—like railway surcharges or Coal India levies—were not really "law" changes. They were commercial decisions by public sector entities.

The Supreme Court rejected that argument. The Court held that any additional charge payable on account of an order, direction, notification, or regulation issued by any instrumentality of the State after the cut-off date qualifies as a Change in Law event. The Court applied Article 12 of the Constitution (the definition of "State" that includes government companies and authorities) to determine which entities counted. Railway Board, Coal India, state governments, central ministries—all were State instrumentalities. Their post-contract impositions were Change in Law events.

The Court specifically listed what qualified: the Busy Season Surcharge, Development Surcharge, and Port Congestion Surcharge imposed by the Railway Board; the Ministry of Environment and Forests' notification on coal quality; forest taxes imposed by state governments; additional levies by Coal India; state-level cesses; and changes under the New Coal Distribution Policy and SHAKTI policy for coal supply. All of these, imposed after the cut-off date, triggered the Change in Law clause.

The interest question: who pays for delay?

The most contentious issue was carrying cost—the interest that accrues when compensation is paid late. The DISCOMs argued that the PPA did not explicitly provide for interest on Change in Law claims. The generators argued that the principle of restitution (restoring the party to the position they would have been in but for the change) required interest from the date the cost was incurred.

The Court sided with the generators. It held that carrying cost is payable at the Late Payment Surcharge (LPS) rate specified in the PPA—which was the State Bank of India base rate plus 2%, compounded monthly. This interest runs from the date of the Change in Law event itself, not from the date of the regulator's order. The Court found this mandated by both the restitutionary principle and the contractual terms in Articles 11.8.3 and 11.3.4 of the PPA.

Why the expert bodies mattered

A significant part of the Court's reasoning was procedural. The CERC, SERCs, and APTEL are specialised tribunals with technical expertise in electricity regulation. The Supreme Court refused to disturb their concurrent findings of fact—meaning both the regulators and the appellate tribunal had reached the same conclusions on most issues. The Court said these findings could only be overturned if they were "perverse, arbitrary, or contrary to statutory provisions." None of the DISCOMs' challenges met that high bar.

This is a crucial point for practitioners. The Court was telling litigants that expert regulatory bodies get deference. A party cannot simply reargue the same facts before the Supreme Court and hope for a different outcome. The challenge must be to the reasoning itself, not to the conclusion.

The specific charges that triggered compensation

The judgment did not stop at a general principle. The Court enumerated the specific charges that qualified as Change in Law events. The Railway Board's Busy Season Surcharge, Development Surcharge, and Port Congestion Surcharge—all imposed after the cut-off date—were included. The Ministry of Environment and Forests' notification that changed coal quality specifications was included. Forest taxes levied by state governments under laws like the Chhattisgarh Adhosanrachna Vikas Evam Paryavaran Upkar Adhiniyam, 2005 were included. Additional levies by Coal India, including the Enhanced Freight Charge, were included. State-level cesses and changes under the New Coal Distribution Policy and SHAKTI policy for coal supply were all included.

For each of these, the Court found that the entity imposing the charge was a State instrumentality under Article 12 of the Constitution. The timing—after the cut-off date in the PPA—was the decisive factor. The Court applied the principle from earlier precedents like Energy Watchdog v. CERC and the Adani Rajasthan case, which had established that post-contract changes by State entities qualify as Change in Law.

Carrying cost: the hidden cost of delay

The carrying cost ruling has significant practical implications. The Court held that the Late Payment Surcharge rate—SBAR + 2%, compounded monthly—applies from the date of the Change in Law event. This means that if a government notification was issued in 2016 and the regulator's order came in 2021, the DISCOM owes compound interest for five years. The rate itself is high: the State Bank of India base rate plus 2%, compounded monthly, translates to an effective annual rate of over 15% in most periods.

For DISCOMs, this creates a powerful incentive to settle Change in Law claims quickly. Every month of delay adds to the interest burden. For generators, it ensures that the compensation is truly restitutionary—restoring them to the financial position they would have been in had the change never occurred.

What this means for power contracts

The judgment resolves a long-standing uncertainty in the power sector. For years, generators and DISCOMs fought over whether post-contract government impositions qualified as Change in Law events. The Supreme Court has now drawn a bright line: if a State instrumentality imposes a charge after the PPA cut-off date, it is a Change in Law event. Period.

For generators, this means the PPA's tariff protection is real. The risk of future government action is allocated to the buyer—the DISCOM—not the seller. For DISCOMs, the message is equally clear: if you want to avoid paying compensation for future government levies, negotiate a different allocation of risk at the contract stage. Do not sign a PPA with a Change in Law clause and then argue that government charges do not count.

A practitioner's perspective sharpens the stakes. Every power sector lawyer now knows that a calculator on the regulator's desk will be running compound interest from the date of the government notification, not from the date of the hearing. The cost of delay in adjudicating Change in Law claims has just become significantly more expensive for DISCOMs. The concurrent findings of the expert bodies—CERC, SERCs, and APTEL—were upheld because they were not perverse. This means that future litigants must focus on the reasoning of these bodies, not simply reargue the facts.

THE PLAY: When drafting or litigating power purchase agreements, treat any post-cut-off-date charge imposed by a government company, board, or authority as a presumptive Change in Law event—and ensure the contract explicitly provides for carrying cost at the Late Payment Surcharge rate from the date of the event, not the date of the regulatory order.

The Court dismissed all appeals. The generators got their compensation. The DISCOMs paid the bill—plus interest.
