Relief in renewable energy disputes is increasingly determined long before lawyers step into a courtroom. Recent appellate rulings show that outcomes are being shaped at the stages of contract execution and project implementation, rather than during legal argument. Developers who treat timelines, notices, and procedural safeguards casually are finding limited tolerance when disputes finally reach adjudication.
Two judgments delivered by the Appellate Tribunal for Electricity (APTEL) on 3rd February 2026 illustrate this shift with unusual clarity.
Talettutayi Solar and the discipline embedded in force majeure
In Talettutayi Solar Projects Four Pvt Ltd v Solar Energy Corporation of India Ltd, the dispute arose from delays in commissioning a 50 MW solar project in Maharashtra under Jawaharlal Nehru National Solar Mission (JNNSM) Phase II, Batch III. The developer invoked demonetisation as a force majeure event, seeking relief from contractual consequences under the Power Purchase Agreement (PPA).
APTEL examined the claim strictly through the framework of the PPA. The agreement required timely notice of any force majeure event and proof that performance had become impossible despite reasonable diligence. These requirements were not satisfied.
No force majeure notice was issued within the stipulated period following demonetisation. The developer also failed to establish a direct causal link between demonetisation and impossibility of performance. As a result, APTEL upheld the encashment of performance bank guarantees and the application of liquidated damages arising from delay.
At the same time, the Tribunal retained the original tariff, as commissioning occurred within the contractual grace period provided under the PPA. This outcome did not dilute the finding of breach. It reflected the operation of the contract as drafted, with different consequences flowing from different levels of delay.
The judgment reinforces a settled position in energy law. Force majeure under a renewable PPA operates through compliance with contractual procedure, evidentiary thresholds, and timing. Invocation after delay has already crystallised rarely succeeds.
Krishna Windfarms and the cost of delayed execution
A different execution lapse lay at the centre of Krishna Windfarms Developers Pvt Ltd v Solar Energy Corporation of India Ltd, involving a 10 MW wind project.
The developer delayed execution of the PPA despite clear timelines set out in the Letter of Intent and repeated reminders. When commissioning was delayed, the developer argued that the Scheduled Commercial Operation Date should be computed from the date of signing rather than from the “effective date” specified in the PPA.
APTEL rejected this contention. It held that contractual provisions defining the effective date governed the timeline for commissioning. A developer could not rely on its own delay in executing the PPA to shift contractual milestones. Performance bank guarantees were validly encashed, and tariff reduction followed as a contractual consequence of delay attributable to the developer.
The ruling underscores the primacy of contractual hierarchy. Definitions and timelines accepted at signing remain binding through execution and enforcement.
A consistent judicial signal across distinct disputes
While the factual settings differed, both decisions reveal a common vulnerability in developer conduct.
In each case:
→ contractual timelines were accepted without contemporaneous objection
→ procedural safeguards under the PPA were not invoked when execution risks emerged
→ legal arguments were advanced only after contractual consequences had accrued
Both projects were ultimately commissioned roughly three months beyond their Scheduled Commercial Operation Dates. Even this degree of slippage attracted financial consequences, underscoring how tightly time risk is now enforced under standard renewable PPAs.
APTEL’s reasoning reflects a tightening alignment with commercial risk allocation. Renewable PPAs are being treated as instruments that price time risk explicitly and enforce it predictably.
Demonetisation and the evidentiary threshold
The treatment of demonetisation in Talettutayi Solar warrants particular attention. The Tribunal did not rule that demonetisation could never qualify as a force majeure event. Relief failed because contractual requirements were not met and impossibility of performance was not established.
This distinction is significant. External disruptions demand contemporaneous documentation, timely invocation, and proof of causation. General assertions of disruption do not meet that standard.
Execution governance as the decisive factor
The deeper lesson from both judgments lies beyond the appellate record.
Each dispute was shaped by choices made during project execution. Contracts were signed without escalation. Delays were not documented in real time. By the time litigation commenced, the contractual position had already hardened.
What these rulings expose is a widening gap within the developer community.
Those who treat PPAs as living risk instruments, actively managed through notices, escalation, and documentation, retain legal headroom when projects slip. Those who treat contracts as static paperwork discover that even modest delays can harden into irreversible legal outcomes. The difference lies less in the event that caused delay and more in how early the risk was recognised and addressed within the contractual framework.
As India’s renewable market matures, adjudicatory reasoning increasingly mirrors project finance logic. Risk that is contractually allocated remains with the party that accepted it.
A message the market should absorb
These decisions reflect more than isolated outcomes. They signal an environment where relief depends on execution discipline rather than post-facto explanation. Courts and tribunals are holding sophisticated developers to the standards embedded in their contracts.
Legal strategy in renewable energy now begins with contract governance and continues through daily compliance. Once timelines slip without timely action, the scope for relief narrows sharply.
As renewable contracts grow tighter and enforcement more predictable, are developers strengthening execution governance or still assuming disputes can be corrected later through litigation?
