Mauritania's prime minister resigns over substation fires, returns within hours
Mauritanian Prime Minister Mokhtar Ould Djay tendered his government's resignation on 9 October after an independent report into two substation fires on 21 and 22 August. President Ghazouani reappointed him the same day and asked him to form a new government.
According to AFP reports carried by Arab News and Africanews on 9–10 October, Prime Minister Mokhtar Ould Djay resigned on Friday 9 October, a day after the report was presented to the president. The official Mauritanian news agency announced that President Mohamed Ould Ghazouani reappointed Djay within hours. Djay was the third prime minister appointed since the start of Ghazouani's second term in August 2024. Sources differ on the spelling of his name; Financial Afrik uses 'El Moctar Ould Djay'.
The report covers fires that broke out less than 24 hours apart, on 21 and 22 August, at two substations owned by the national power company Somelec. The outages left much of the capital Nouakchott and the towns of Ouad Naga, Idini and Aouleigat in darkness for 3 to 5 days. An independent commission chaired by Ousmane Mamoudou Kane found serious failings in prevention, electrical protection, work supervision and emergency management. It found no sabotage or operator error.
The commission identified overheating as the most likely cause. It pointed to connectors imported by a private company that did not meet technical standards, together with 3 newly installed transmission lines, as the source of the problem. The report placed responsibility on Somelec and officials of the energy ministry. Somelec announced full repairs at both substations, which took about 5 days. As of 10 October, it had not been announced who would hold the energy portfolio in the new cabinet.
Talay assessment
Bottom line
Resignation and reappointment on the same day show accountability being shifted from the individual to the institution. Because the report rules out sabotage and points to substandard imported connectors, the real constraint is procurement oversight and grid maintenance. The likeliest path is a reshuffle focused on the energy ministry and Somelec's management. The risk of another failure on the Nouakchott grid falls only if tendering and inspection rules are tightened.
Likely effects
- Critical infrastructureNegative1–6 months
Substandard equipment on 3 new lines showed the capital's grid can fail from a single point; similar imports at other substations need inspection.
- Political stabilityUncertainWeeks
Ghazouani is trying to absorb the backlash by keeping his prime minister and renewing the cabinet, which contains the government crisis in the near term.
- Public procurementUncertain6 months+
Tracing the failure to equipment imported by a private company puts Somelec's procurement and acceptance-inspection processes at the centre of political debate.
Possibilities, ranked
- 1Purge of energy management55%
The energy minister is replaced in the new cabinet, Somelec's management is overhauled and inspection of imported equipment tightens.
Watch: Appointments to the energy ministry and Somelec's director-general post in the new cabinet list
- 2Cosmetic change30%
The cabinet stays largely the same and those named in the report keep their posts.
Watch: Most ministers being reappointed and no prosecutorial step on the report
- 3New grid failure15%
Another fire or outage at the repaired substations or on the new lines reignites political pressure.
Watch: Somelec announcing a new outage in Nouakchott lasting more than a few days
