On September 17, 2026, an International Arbitration Tribunal under the International Chamber of Commerce in Paris ruled in Nigeria's favor, dismissing claims by Sunrise Power and Transmission Company Ltd (Sunrise) totaling around $3.38 billion. The disputes were linked to the Mambilla Hydroelectric Power Project in Taraba State.
President Bola Ahmed Tinubu announced the decision in a statement, noting that the ruling supports Nigeria's stance on defending itself against financially adverse claims. The tribunal ruled against Sunrise's $680 million settlement demand with interest and their $2.7 billion compensation claim. President Tinubu highlighted the Nigerian government's commitment to defending the country's interests while maintaining relationships with legitimate investors.
Key contributors to the legal victory included Nigeria's legal and government teams, former Presidents Olusegun Obasanjo and Muhammadu Buhari, and numerous witnesses and experts. The Mambilla Hydroelectric Power Project has been a source of multiple disputes, including a previous $200 million settlement and an additional $400 million claim, which rose to about $680 million with interest.
This ruling follows other significant legal victories for Nigeria, including a recent win against European Dynamics UK Ltd in February 2026.
