Adesanya's name emerged in three out of seven-count charges filed against Olu Agunloye, the former minister of power and steel. Agunloye is currently being prosecuted by the EFCC over the $6 billion Mambilla hydropower contract. The charges allege corrupt transactions, including suspicious payments traced from Sunrise Power and Transmission Ltd to Agunloye’s bank accounts.

In one specific count, the EFCC claims that on August 10, 2019, Agunloye corruptly received the sum of N3,600,000.00 through his Guaranty Trust Bank account from Sunrise Power and Transmission Company Limited (SPTCL) and Leno Adesanya for approving the Mambilla Hydroelectric Power Station project.

Former President Olusegun Obasanjo has publicly challenged Agunloye to explain the authority behind awarding a $6 billion contract to Sunrise for the Mambilla hydropower project in 2003.

Sunrise Power is currently engaged in arbitration with Nigeria at the International Chamber of Commerce (ICC) in Paris, France. The company alleges a breach of contract, asserting that it was awarded a $6 billion build, operate, and transfer (BOT) contract in May 2003 by the Obasanjo administration, but the federal government subsequently repudiated the agreement. The ongoing legal proceedings highlight the complexities surrounding the Mambilla hydropower project and its historical contractual disputes.
