Nigeria’s Aliko Dangote and Kenyan President William Ruto have broken ground on a $16 billion oil refinery in Lamu, Kenya, that is designed to reduce East Africa’s reliance on imported refined petroleum. The facility, scheduled for completion in 2030, will be modeled partly on Dangote’s 700,000-barrel-per-day refinery in Nigeria. Ruto said the project, Kenya’s largest-ever foreign direct investment, could increase annual GDP by 12%. To support the refinery, Dangote plans to build a 1,000-megawatt power plant, double that of its Nigerian counterpart. The refinery is expected to support Lamu Port and create more than 50,000 jobs. However, questions remain over how it will secure crude supplies. Environmentalists also fear damage to Lamu Old Town, a World Heritage site, and have challenged the project in court.
