Nigeria’s former Minister of Power, Saleh Mamman, has been a prominent figure in the country’s public service landscape, from his early career in education and state civil service to his rise into federal cabinet and eventual dramatic fall following a landmark corruption conviction.
His story reflects a full arc often seen in Nigerian public life: long years of administrative service, political elevation, and a controversial exit shaped by allegations of large-scale financial misconduct.
Early Life and Background
Saleh Mamman was born on 2 January 1958 and hails from Taraba State in northeastern Nigeria.
Like many public servants of his generation, his early life was shaped by technical education and government service rather than political exposure.
He began building his professional foundation through technical training, eventually earning a Higher National Diploma (HND) in Electrical/Electronics from Kaduna Polytechnic in 1988.
Years later, he expanded his academic profile with a Master of Business Administration (MBA) in Business Administration from Bayero University Kano, which he completed in 2015 — a qualification that came decades after his early career had already begun.
Early Career in Public Service
Mamman started his professional journey in 1981 as a teacher at a Technical School in Mubi, Adamawa State.
This early role placed him in the education sector, where technical knowledge and vocational training were central.
In 1992, he transferred his service to the Taraba State civil service, where he continued to build his administrative career within the public sector.
Over time, he rose through the ranks and eventually attained the position of Assistant Director in the Taraba State Ministry of Works, a senior administrative role that reflected years of bureaucratic experience.
He retired from the civil service in 2002, after more than two decades of public service, before transitioning into private business and political engagements.
Entry Into Politics and Federal Appointment
Mamman’s political rise reached its peak in August 2019 when he was appointed Minister of Power under the administration of former President Muhammadu Buhari.
He was sworn in on 21 August 2019 following nomination and Senate confirmation, taking charge of one of Nigeria’s most sensitive and challenging ministries — electricity generation, transmission, and distribution.
At the time of his appointment, the power sector was already under intense public scrutiny due to persistent grid instability, low generation capacity, and structural inefficiencies.
As minister, Mamman was tasked with overseeing reforms aimed at improving electricity supply, expanding infrastructure, and stabilising the national grid.
Exit From Office
His tenure as Minister of Power was relatively short-lived. On 1 September 2021, he was removed from office and replaced by the Minister of State for Works and Housing, Abubakar Aliyu.
The reasons surrounding his exit were not heavily detailed at the time, but it came amid broader scrutiny of performance and management challenges within the power sector.
Legal Troubles and Corruption Conviction
Years after leaving office, Mamman became the subject of a major corruption case involving allegations of large-scale financial mismanagement tied to power infrastructure projects.
In a landmark ruling at the Federal High Court in Abuja, Justice James Omotosho sentenced him to 75 years in prison over his involvement in a ₦33.8 billion fraud case.
The court ruled that the sentences on multiple counts would run consecutively, effectively amounting to a total of 75 years.
The judgment also ordered that the sentence would take effect from the moment he is arrested, with all security agencies, including Interpol, directed to ensure his arrest wherever he is found.
In addition, the court ordered the forfeiture of all recovered funds and properties linked to him to the Federal Government.
He was also directed to refund outstanding sums related to the ₦22 billion allocated for the Mambilla and Zungeru hydroelectric power projects.
The ruling represents one of the most significant corruption convictions involving a former senior government official in Nigeria’s power sector.
Legacy and Public Perception
Mamman’s career presents a complex legacy — one that spans decades of civil service, a rise to federal leadership, and a dramatic legal downfall.
While his early career reflects long-term engagement in public administration and technical governance, his post-ministerial years have been dominated by legal proceedings and corruption allegations.
His case has also reignited public debate around accountability in Nigeria’s power sector, especially regarding large infrastructure projects and government spending transparency.
Conclusion
From a classroom teacher in Adamawa to Nigeria’s Minister of Power, and ultimately to a high-profile corruption conviction, Saleh Mamman’s story is one of the most striking examples of the rise and fall of a public official in recent Nigerian history.
