A star witness in the ongoing prosecution of the alleged $6 billion Mambilla Hydroelectric Power Project fraud has testified before the Federal High Court, revealing that the Federal Executive Council (FEC) explicitly ordered the withdrawal of a contract memo related to the project. The testimony provides a rare glimpse into the administrative maneuvers behind one of Nigeria’s most controversial and long-delayed infrastructure assets. For the Nigerian economy, the unraveling of the Mambilla fraud case is a critical litmus test for institutional integrity and the rule of law, as the project—intended to provide 3,050 megawatts of electricity—remains a phantom asset that has drained billions in public funds without delivering a single kilowatt to the national grid.
The witness, a former senior government official, detailed how the FEC directed the Ministry of Power to retract the memo amid mounting concerns over legal encumbrances and procurement irregularities. The withdrawal of the memo suggests that top-level government officials were aware of the potential for litigation and financial mismanagement long before the project stalled. From a business journalism perspective, the Mambilla saga represents a massive “opportunity cost” for the Nigerian industrial sector. The $6 billion that was allegedly misappropriated could have revitalized the nation’s manufacturing hubs, reduced the “energy poverty” that forces businesses to rely on expensive diesel generators, and improved the overall ease of doing business in West Africa’s largest economy.
The fiscal implications of the Mambilla fraud are profound, particularly regarding Nigeria’s sovereign credit rating and its relationship with international lenders, including the Export-Import Bank of China. The legal gridlock surrounding the project has stalled $5.8 billion in potential foreign financing, as lenders are unwilling to release funds for a project mired in criminal litigation and contractual disputes. This loss of foreign direct investment (FDI) has direct consequences for the Naira, as the expected inflows of foreign exchange to fund the construction never materialized, contributing to the long-term liquidity squeeze in the FX market.
Furthermore, the testimony highlights the systemic vulnerabilities in Nigeria’s public procurement process. The fact that a $6 billion project could be derailed by fraudulent claims of “consultancy fees” and “settlement agreements” underscores the urgent need for the “Renewed Hope” administration to implement more robust digital oversight and transparency in the Bureau of Public Procurement (BPP). For the Nigerian power sector to attract the $10 billion in annual investment needed to achieve grid stability, investors must be assured that large-scale projects like Mambilla are immune to the “contract padding” and administrative sabotage revealed in this court case.
From a political economy standpoint, the Mambilla prosecution is an essential step toward restoring trust in the government’s ability to execute critical infrastructure. The failure of the project has left the Mambilla Plateau—a region with immense agricultural and tourism potential—disconnected from the national economic mainstream. The judicial outcome of this trial will determine whether Nigeria can successfully “claw back” misappropriated assets and send a signal to the global community that the era of “ghost projects” and impunity in the power sector is over.
As the court adjourns for further evidence, the focus remains on the structural reforms needed to prevent a repeat of the Mambilla disaster. For Nigeria to achieve its goal of a $1 trillion economy, it must move beyond the “litigation phase” of its infrastructure development and into an “execution phase” characterized by transparent bidding, secure financing, and rapid project delivery. The Mambilla testimony is a sobering reminder that without institutional integrity, even the most ambitious economic visions can be grounded by the weight of administrative fraud.
