What Happened
On August 26, 2026, the Singapore International Commercial Court (SICC) dismissed Tata Power's challenge to arbitration awards issued in favor of Kleros Capital Partners Limited.
The underlying arbitration, initiated at the Singapore International Arbitration Centre (SIAC) in November 2020, concerned Tata Power's alleged breach of agreements and duties owed to Kleros.
The SIAC tribunal issued two key awards: a liability award in September 2023 and a damages award on July 1, 2025, ordering Tata Power to pay Kleros USD 490.32 million plus 5.33% annual interest from November 2020.
Tata Power contested the awards and the appointment of the arbitrators, but the SICC found no breach of natural justice or fair hearing.
Tata Power now has 28 days from the SICC decision to appeal to the Singapore Court of Appeal.
Context
The dispute stems from a project for which Tata Power and Kleros had confidentiality and cooperation agreements.
The arbitration panel included prominent experts and a retired Indian Supreme Court judge.
Interest on the award continues to accrue until payment, and previous applications by Tata Power regarding tribunal constitution were also dismissed.

- The outcome has direct financial implications, requiring Tata Power to pay a substantial sum to Kleros.
- This case highlights Singapore's role as a hub for high-value cross-border dispute resolution.
