Uganda's power sector structure is among the most sophisticated in Sub-Saharan Africa, and Uganda is one of only a handful of countries in the region where tariffs are close to being cost reflective. While reforms were swift and comprehensive, following the 1999 Electricity Act, significant difficulties were encountered along the way that prevented the benefits of reform from materializing until much later. The failed first attempt with the Bujagali Hydropower independent power producer left the country heavily exposed to the 2005/06 and 2010/12 droughts, which in turn created difficulties for the new private distribution utility, Umeme, and led to a relaxation of the regulatory performance targets for the concession. This situation led to a buildup of frustration with the new operator and the launch of two public enquiries, which recommended termination of the concession. In 2012, with the easing of drought conditions and the completion of the Bujagali Hydropower Project following a second independent power producer arrangement, there was improvement in the availability of power. This made it possible to set more demanding performance targets for the concessionaire, Umeme, which fed through into substantial improvements in operational efficiency and accelerating service coverage. Although the reform model was eventually able to deliver results, the associated cost was comparatively high. Furthermore, the extension of the private concession model to financially unviable rural areas did not prove to be successful. Access rates began to pick up only following the adoption of a revised approach in 2012, built around government-led and donor-funded expansion of rural networks.
