  • Legal dispute hampers plans to access Chinese project funding
  • Plan for giant hydropower plant dates back to early 1970s

A Nigerian company that lost out on a contract to build a multibillion-dollar hydropower plant has filed a $400 million arbitration claim against the nation’s government, further hampering its plans to access Chinese financing for the project.

Sunrise Power & Transmission Co. accuses the government of reneging on a settlement accord agreed last March that was supposed to resolve a long-running dispute over the rights to construct the Mambilla facility. The company filed a case at the International Chamber of Commerce in Paris on May 11, asking a tribunal to order President Muhammadu Buhari’s administration to honor the agreement, its lawyer Femi Falana said by phone.

Export-Import Bank of China has agreed to help fund Mambilla, but won’t release the money until the legal standoff ends. Prior to Sunrise filing its case, Nigeria’s Power Ministry said its preferred financing option remained a bilateral sovereign loan from the Chinese state lender.

“There is no reason for an additional arbitration or court case,” Aaron Artimas, a spokesman for Power Minister Saleh Mamman, said by phone on Friday. “The government is working to find an amicable solution with Sunrise.”

Electricity Shortfall

China Eximbank and Buhari’s representative didn’t respond to requests for comment.

If completed, Mambilla will bolster the 13,000 megawatts of installed electricity-generating capacity in Africa’s biggest economy by 12%. Poor maintenance of existing infrastructure means that only about 4,500 megawatts is dispatched to the grid daily — a fraction of what’s needed in a nation of more than 200 million people. Buhari said in October the project will bring power to 3 million homes.


Plans to develop the $4 billion, 1,525-megawatt plant on the Donga River in the eastern Taraba state date back to the early 1970s, but the project got off to multiple false starts. Initially intended to be a 3,050-megawatt facility that would cost $5.8 billion, the Power Ministry told Bloomberg in March that it scaled back the scope of the project to improve its “bankability.”

Former Power Minister Babatunde Fashola announced in 2017 that China Eximbank would finance 85% of the cost of Mambilla, and that it would be built by Sinohydro Corp., China Gezhouba Group Co. and China Geo-Engineering Corp. The three Chinese companies didn’t respond to questions.


Legal Disputes

A memorandum written by the Chinese contractors to Mamman in September 2019, seen by Bloomberg, stated that Eximbank can’t enter “substantive financing negotiations” while the development is encumbered by legal disputes. Yang Jiechi, China’s top diplomat and a ruling Politburo member, notified Buhari the same month that the funding can’t be disbursed until the tussle with Sunrise ends, according to the memorandum.

The Power Ministry first granted Sunrise the contract to build Mambilla in 2003, a deal Nigeria’s Federal Executive Council declined to approve. The company has asserted a claim to the project ever since, first in a Nigerian federal court and more recently through international arbitration.


After Fashola finalized the arrangement with the three Chinese firms, Sunrise started proceedings against Nigeria’s government at the ICC, demanding between $960 million and $2.4 billion in damages. It suspended that case to participate in the settlement talks encouraged by Yang.

Last year, Mamman and Nigerian Attorney General Abubakar Malami concluded two agreements with Sunrise that committed the government to pay $200 million to the Lagos-registered company in return for it dropping all claims relating to Mambilla. Sunrise would be entitled to an additional $200 million plus interest if the government failed to transfer the agreed sum within 180 days, according to the second accord signed in March, which was seen by Bloomberg.

No Money

Buhari subsequently decided that his administration couldn’t pay the settlement sum, according to a memorandum Malami sent the president in August, at a time when low oil prices were hammering government income in Africa’s biggest crude producer.

Sunrise hasn’t received any money “despite numerous commitments from the involved ministers and a surge in oil prices,” Falana said. The company’s request for an award of $400 million plus interest of 10% has been initiated under the ICC’s expedited procedure rules, as specified in the agreements, and should be adjudicated within six months, he said.


Malami’s memorandum to Buhari stated that Sunrise is “in a strong legal position to pursue a successful claim” having not been “duly disengaged as contractor.” Further delays caused by the dispute could also have “major negative political implications” because Mambilla is a “signature project” for the president’s administration, Malami said in August. His office didn’t respond to a request for comment.

Buhari set up a Mambilla delivery committee in February 2020 to advance the project. Despite financing problems, activities such as land acquisition and public awareness raising are underway, Mamman said on his Twitter account last month.


“The government is on course and remains committed to the project,” Artimas said.
