Tata Power shares fall over 4% after Singapore court dismisses challenge to $490 million award

Tata Power's shares experienced a decline of more than 4% on Thursday following the Singapore International Commercial Court's decision to reject the company's appeal against arbitral awards related to a dispute over a coal asset in Russia. The company's stock was trading at ₹349.80 by 12:18 pm, close to the day's lowest point of ₹348.10, in contrast to its close on Wednesday of ₹364.

As of the current time, the company's market capitalization is valued at ₹1.11 lakh crore. The challenge against the arbitral awards, which amounted to $490 million, was initiated by Kleros and arose from allegations that Tata Power breached an agreement with an investor to bid for a coal asset in Russia. The arbitration proceedings began on November 30, 2020, and the company also contested the Singapore International Arbitration Centre (SIAC) Court's decision on June 5, 2025, rejecting its challenge to the appointment of two arbitrators who issued the majority arbitral award.

The Singapore International Commercial Court rejected Tata Power's appeal, ruling that there was no violation of natural justice or the fair hearing principle in the majority's final award. The company has been granted 28 days from August 26, 2026, to appeal to the Singapore Court of Appeal.
