The shareholders of Kenya Oil Refinery have resolved to inject 7.8 billion shillings to upgrade the facility. This will however depend on the outcome of an impact assessment study of the intended upgrading and further consultations with the neighbouring countries of Uganda and Tanzania. The facility, built in early 1960s, needs to be upgraded to modernise it and allow it refine unleaded fuel products. The Kenya Government, Shell Oil company, British Petroleum (BP) and Caltex jointly own the facility.
