Africa’s richest man, Alhaji Aliko Dangote, plans to invest up to $8bn to build a Nigerian oil refinery with a capacity of around 400,000 barrels a day by late 2016, the tycoon said on Tuesday. This will almost double Nigeria’s current refining capacity. “This will really help not only Nigeria but sub-Saharan Africa. There has not been a new refinery for a long time in sub-Saharan Africa,” Dangote said in a telephone interview. The country currently has the capacity to produce some 445,000 barrels per day among four refineries, but they operate well below that owing to decades of mismanagement and corruption in Africa’s leading energy producer. Nigeria, the continent’s second biggest economy, relies on subsidised imports for 80 per cent of its fuel needs. A surge in domestic capacity would be welcomed by investors in Nigeria, but it would cut into profits made by European refiners and oil traders who would lose part of that lucrative market. Dangote said the country’s ability to import fuel would soon be challenged. “In five years, when our population is over 200 million, we won’t have the infrastructure to receive the amount of fuel we use. It has to be done,” he said. Past efforts to build refineries have often been delayed or cancelled, but analysts have said Dangote should be able to build a profitable Nigerian refinery, owing to his past successes in industry and his strong government connections. The Dangote Group’s cement manufacturing, basic food processing and other industries have helped lift his personal fortune to $16.1bn from $2.1bn in 2010, according to the latest Forbes estimate.
