Nigeria’s power catastrophe: 60-year trail of broken promises, stolen billions, nuanced betrayal

For six decades, Nigeria has been running on a lie. We are told that electricity is the bedrock of civilisation, that no nation has ever escaped poverty without reliable power. Yet today, Africa’s largest economy generates less than 4,100 megawatts for 220 million people less than a single data centre in Virginia. This is not […]

For six decades, Nigeria has been running on a lie. We are told that electricity is the bedrock of civilisation, that no nation has ever escaped poverty without reliable power. Yet today, Africa’s largest economy generates less than 4,100 megawatts for 220 million people less than a single data centre in Virginia. This is not a technical failure; it is a national betrayal.

The tragedy begins with a promise that became a curse. In 1999, President Olusegun Obasanjo appointed Chief Bola Ige as Minister of Power. Standing before a hopeful nation, Ige vowed to stabilise electricity within six months. Six months passed. The lights did not stay on. Two years later, a frustrated Ige was moved to become Attorney-General a tacit admission that the power sector could break even the finest minds. That lesson has been ignored by every administration since. Instead of fixing fundamentals, governments turned the sector into a looting ground. Under Obasanjo, the $16 billion National Integrated Power Project saw $2.3 billion vanish into political campaigns. Under Goodluck Jonathan, privatisation raised $3.36 billion from selling generation and distribution companies, but the power never came. In 2014, the Office of the National Security Adviser allegedly diverted $2.1 billion of NIPP funds to private accounts. The Zungeru hydro contract was inflated from $1.3 billion to $1.9 billion, with $220 million in kickbacks traced to a Swiss court.

Then came the Buhari years. The $2.3 billion Siemens deal was meant to deliver 7,000 megawatts. By 2023, only 20 per cent of the work was done, and $280 million had disappeared into “consultancy fees.” The national grid collapsed 56 times between 2015 and 2023. By 2026, the sector’s total debt had ballooned to 6.2 trillion.

The most damning evidence of systemic rot is the contrasting fates of three former ministers. In April 2026, Saleh Mamman was convicted of laundering 33.8 billion and sentenced to 75 years in prison. That judgment was delivered at the very time he was attempting to pick a nomination form to run for governor in his home state- a staggering act of deviance that shows how little these figures fear the consequences of their crimes. Swift justice, the public cheered. Yet Dr. Olu Agunloye, Minister of Power from 1999 to 2003, stands accused of a far larger crime: unilaterally awarding the 3,960‑megawatt Mambilla hydro contract valued at $6 billion without Federal Executive Council’s approval, and allegedly forging documents. His case has dragged for years, while Nigeria fights a parallel arbitration in Paris to avoid paying billions in damages. The public sees a glaring disparity: one minister jailed quickly, another walking free despite a $6 billion scandal.

But there is a third case that adds critical nuance- Professor Barth Nnaji. Appointed Minister of Power in 2011, Nnaji brought impeccable credentials: a PhD in industrial engineering, multiple patents, and his own power company, Geometric Power. Yet he never fully disentangled himself from that company. Geometric Power was shortlisted to bid for the Afam power plant, a crown jewel of privatisation. The Nigeria Labour Congress (NLC) called for his resignation, accusing him of allegedly diverting “major businesses meant for PHCN to his private companies.” By August 2012, after a power struggle with the president’s adviser, Nnaji was forced to resign. He was never charged with any crime. He returned to his business and today his Geometric Power plant in Aba operates as one of the few decentralised successes. This ambiguity, an official who may have overstepped ethical boundaries but was never prosecuted, who was removed yet continued to build power, captures the peculiar tragedy of Nigeria’s electricity industry. The sector has been looted on a monumental scale, but it has also been hampered by conflicts of interest in grey areas, by the difficulty of distinguishing genuine reform from self‑enrichment.

The technical numbers tell the rest of the horror story. As of March 2026, installed capacity stands at 13,625 megawatts. But available operational capacity is just 4,089 megawatts. Over 9,500 megawatts sit completely idle more than the entire grid of many African nations. Gas plants cannot run because producers are owed 3.3 trillion. Hydro plants are choked by silt. The transmission company, TCN, operates with circuit breakers from the 1970s, no real‑time monitoring, and a budget less than 10 per cent of what is needed. Even if every power plant worked, TCN cannot wheel more than 5,500 megawatts safely. And the 11 distribution companies collect barely 55 per cent of what they bill, losing another 45 per cent to theft and old feeders.

Yet there is a twist. While the federal government has failed spectacularly, state governments are now bypassing Abuja entirely. Imo State launched “Light Up Imo,” secured a transmission substation, and is pushing its 375‑megawatt Egbema plant. Kano, Katsina and Jigawa signed a 50 billion tri‑state electrification deal covering nearly 40 million people. Off‑grid solar now accounts for 1,150 megawatts 96 per cent of Nigeria’s solar capacity valued at $2.5 billion. And then there is Aliko Dangote. On May 6, 2026, he announced he is going into power – 20,000 megawatts. That is one‑and‑a‑half times the country’s entire installed capacity, from a single private investor. If true, it could transform Nigeria. But here is the cliffhanger: Even if Dangote builds 20,000 megawatts tomorrow, where will it go? The national grid cannot wheel more than 5,500 megawatts. Without transmission, that power is stranded. So the question becomes: will Dangote also build his own grid? And what happens to the bankrupt GenCos and DisCos when the private sector simply abandons them?

Next week, in the concluding part of this investigation, I will answer those questions. I will show why privatisation failed, what Ghana and Egypt did right that Nigeria did not, and the four urgent steps that Minister of Power Joseph Tegbe must take including the one thing that terrifies the political class: a dedicated anti‑corruption court for power fraud that can handle even the grey areas that the Nnaji case exposed. The darkness is not inevitable. But the light will only come when Nigerians demand accountability, not promises.
