Tata Power Loses Singapore Court Bid Against $490 Million Kleros Award; Appeal Next
The Singapore International Commercial Court (SICC) has dismissed all applications filed by Tata Power to set aside a $490.32 million (about ₹4,900 crore) arbitration award in favour of Kleros Capital Partners. The judgment came on August 26, and the company has said it will appeal before the Singapore Court of Appeal. If the appeal fails, Tata Power could end up paying more than ₹5,000 crore including interest and costs. Kleros puts its own figure higher, at roughly ₹6,000 crore. The stock fell about 4% the day after the ruling, touching a seven-month low.
Dispute Over a Russian Coal Project
The case relates to the Krutogorovo coal project in Russia. According to Business Standard, Kleros started arbitration in November 2020, alleging breach of confidentiality and other contractual obligations. INDmoney reports that the allegation was that Tata Power used confidential information and shut Kleros out of an opportunity the two sides had originally explored together.
In September 2023, the tribunal held Tata Power liable for breach of the relevant agreements. On July 1, 2025, a three-member tribunal, by a 2:1 majority, fixed the damages.
What the Award Includes
Going by Tata Power's exchange filing:
- Principal damages: $490.32 million
- Interest: 5.33% simple interest per annum from November 30, 2020 until payment
- Arbitration costs: about $8.29 million, with 5.33% interest from July 1, 2025
Sahi reports that the SICC has also directed Tata Power to pay legal costs of SGD 11.34 million. Interest on the principal alone works out to roughly $26 million a year, or about $71,000 a day. Kleros claims the total liability has crossed $640 million. At about ₹95 to the dollar, that is ₹6,000-6,100 crore. This is Kleros' own calculation, not a fresh award from the court.
Court Rejects All Three Grounds
The SICC held that the majority of the tribunal did not breach natural justice or fair hearing rules. According to NewsDrum, the court also said Tata Power failed to show that the tribunal ignored causation, remoteness and mitigation while fixing damages. The allegation of apparent bias linked to the third-party funder backing Kleros' claim did not hold either. Tata Power's challenge to the SIAC Court's June 5, 2025 decision on the appointment of two arbitrators was also dismissed.
Tata Power maintains that principles of natural justice were violated. Acting on legal advice, it has not made a provision for the liability in its books.
Appeal Does Not Mean Immediate Relief
Saur Energy reports that filing an appeal does not automatically halt enforcement. Without a stay, Kleros could try to enforce the award in jurisdictions where Tata Power or its group companies hold assets. Sahi reports that Kleros has said the amount is due immediately. The 28-day window to appeal ended on September 23. The company had announced it would appeal within the deadline, but we have not been able to confirm the filing.
Tata Power Share Price: One-Year Report Card
Tata Power closed at ₹367.50 on the NSE on September 25, according to Kotak Neo data. The stock is down about 4.8% over one year and about 5.9% over six months. Its three-year return is around +43%. The 52-week range is ₹342.50 to ₹464.90. On September 30, at around 2:23 pm, the stock was quoting near ₹359 (Screener), roughly 23% below its 52-week high. Market capitalisation is about ₹1.15 lakh crore. There was no fresh development in the Kleros case on September 30, and the stock saw no big move.
What Next for Tata Power Shares
The market has known about the award since 2025. What is new is that the legal route has narrowed after the SICC loss.
Business Today cited a Nuvama note. The brokerage estimates the impact of the full $640 million liability at about ₹20 per share. Separately, about ₹5,000 crore of incremental debt by FY28 to fund capex adds a ₹17 per share impact. After the stock corrected 8%, Nuvama upgraded it to BUY from HOLD and set a Bull Case target of ₹421 (earlier ₹400). Its Bear Case of ₹363 assumes the full Kleros liability and gives no value to the PSP and Bhutan hydro projects. The stock is now trading near that Bear Case. This is one brokerage's estimate.
Three paths lie ahead:
- Appeal succeeds or a stay is granted: The overhang lifts. Against Nuvama's Bull Case of ₹421, there is room for about 17% upside from current levels.
- Appeal is dismissed: A payout of around ₹6,000 crore is about 5% of market cap and exceeds FY25 net profit of roughly ₹4,775 crore. If funded by debt, financing the capex plan of about ₹16,000 crore gets costlier.
- The case drags on: Interest keeps running at about ₹68 lakh a day, and the stock could swing between ₹350 and ₹375 on legal headlines.
The business growth story is intact, but the case will remain an overhang until the Court of Appeal's stance becomes clear.
For traders
- Swing (1-4 weeks): ₹348-350 is key support. A close below could add to weakness. Resistance sits at ₹375-380.
- Positional (1-3 months): News on a stay or the appeal hearing will be the big trigger.
- Long term: Renewable growth is strong, but legal uncertainty argues for staggered entry.
Key Signals to Watch
- Confirmation of the appeal filing and the hearing date
- The Singapore court's stance on a stay of enforcement
- Company commentary on provisioning in Q2 FY27 results
- Any Kleros move to enforce against overseas assets
30-Second Summary
The SICC dismissed all of Tata Power's applications against Kleros' $490.32 million award. Kleros' total claim is about ₹6,000 crore. The company will appeal and has made no provision. The stock is near ₹359, down about 5% in a year.
