Tata Power is pursuing legal measures in Singapore to prevent the sale of its shareholdings in two Singapore-based subsidiaries as it faces an arbitration-related claim exceeding 650 million dollars from investment firm Kleros Capital Partners. The dispute has intensified following enforcement proceedings initiated in Singapore, where a court-appointed officer has served notices for the attachment of Tata Power's shares in the two entities.
The Indian power company has informed that its shareholdings in the subsidiaries are already pledged to a consortium of lenders. Tata Power is challenging the Singapore International Commercial Court's decision before the Singapore Court of Appeal and is also seeking to defer the sale process until its appeal is decided.
The two subsidiaries involved are Bhira Investments Pte Ltd and Tata Power International Pte Ltd. The enforcement proceedings are connected to arbitration awards issued in favour of Kleros over a dispute involving a Russian coal exploration project.
Singapore Court Authorises Enforcement Proceedings
The Singapore International Commercial Court dismissed Tata Power's applications to set aside the arbitration awards on August 26, 2026. Following the dismissal, the awards were recognised as court judgments, allowing enforcement proceedings to move forward.
On November 6, 2026, notices were served on Tata Power's two wholly owned Singapore subsidiaries, informing them that the company's shareholdings in the entities had been attached by the court-appointed Sheriff.
According to Tata Power's regulatory disclosures, the attachment relates to an enforcement value of up to 830.77 million Singapore dollars. The company has stated that the shares are pledged in favour of a consortium of lenders associated with the respective subsidiaries.
Tata Power is now pursuing objections to the enforcement proceedings. If Kleros contests the company's objections, the Sheriff may direct Tata Power to file an application before the Singapore International Commercial Court seeking the release of the shares.
The company has clarified that the sale or delivery process can begin only after the release application is decided by the court. Any decision on that application may also be subject to further appeal.
Why Is Tata Power Facing a 650 Million Dollar Claim?
The legal dispute between Tata Power and Kleros Capital Partners originated from agreements signed in 2013 and 2014 concerning the proposed joint development of the Krutogorovo coal deposit in Russia's Kamchatka region.
Under the agreements, the two parties explored opportunities to develop the coal deposit together. Kleros reportedly shared confidential business plans and geological information related to the project with Tata Power.
Kleros later alleged that Tata Power used the confidential information to pursue the coal project independently, excluding the investment firm from the proposed development arrangement.
The disagreement eventually led to arbitration proceedings in Singapore. Kleros initiated the proceedings in November 2020 before the Singapore International Arbitration Centre.
On September 26, 2023, a three-member arbitral tribunal found that Tata Power had breached certain contractual obligations under the agreements, including obligations relating to confidentiality and good faith.
The tribunal subsequently issued an award directing Tata Power to pay 490.32 million dollars in damages for the alleged loss of opportunity. The award was issued in July 2025, with a final award following in August 2025.
The amount claimed by Kleros has since increased beyond 650 million dollars after the addition of interest and legal costs. The award also carries simple interest at 5.33 percent annually from November 30, 2020, on the damages amount.
Tata Power Appeals Against the Singapore Court Ruling
Tata Power has challenged the Singapore International Commercial Court's decision before the Singapore Court of Appeal. The company is continuing its legal efforts to contest the enforcement of the arbitration awards.
According to the company's regulatory filing, its notices of appeal were filed in September 2026 and accepted by the court. The appeal hearing is scheduled for January 19, 2027.
The court has also set deadlines for the written submissions. Tata Power is required to submit its written arguments by November 23, 2026. Kleros must submit its response by December 14, while Tata Power's reply submissions are due by December 24, 2026.
The appeal is an important part of the company's legal strategy. However, filing an appeal does not automatically suspend enforcement proceedings. This means Tata Power must separately pursue legal remedies if it wants to prevent the sale process from moving forward while the appeal remains pending.
Shares Already Pledged to Banks
One of the key issues in the enforcement proceedings is that Tata Power's shareholdings in the two Singapore subsidiaries are already pledged to lenders.
The company has stated that the shares are pledged in favour of the respective subsidiaries' lender consortiums. This could make the enforcement and potential sale process more complicated, as the existing lender interests will also need to be considered.
Tata Power's management has indicated that the process of selling the shares may take considerable time because of the existing pledges and the legal procedures involved.
The company is seeking to file objections to the enforcement proceedings and obtain a deferment of the sale process from the court-appointed Sheriff while its appeal is pending.
What Are the Subsidiaries Involved?
Bhira Investments and Tata Power International form part of Tata Power's overseas investment structure.
Bhira Investments holds the company's international coal mining interests, including its 30 percent stake in PT Kaltim Prima Coal in Indonesia. The Indonesian mining investment is among the overseas assets connected to the subsidiary.
Tata Power International serves as an overseas investment holding vehicle for the company and is associated with its international business interests.
The potential sale of shares in these entities has therefore become an important issue for Tata Power, as the proceedings involve its overseas investment structure.
Financial and Business Implications
The legal dispute has attracted attention from investors because the amount claimed by Kleros is substantial. The final financial and business implications will depend on the outcome of Tata Power's appeal, the enforcement proceedings and any decisions concerning the pledged shareholdings.
Tata Power has stated in its financial disclosures that it has not made adjustments to its consolidated financial results for the quarter ended September 30, 2026, pending the outcome of the appeal and enforcement proceedings. The company has relied on advice from its legal counsel while pursuing available remedies.
The dispute highlights the legal and financial complexities that can arise from international business agreements, overseas investments and cross-border arbitration.
For now, Tata Power is seeking to prevent the sale of its Singapore subsidiary shares while continuing its legal challenge. The next major developments are expected from the Singapore Court of Appeal hearing scheduled for January 19, 2027, and the separate proceedings concerning the enforcement and possible release of the attached shares.
The outcome could have implications for Tata Power's overseas investment holdings and its financial exposure to the arbitration dispute.
