This report updates previous African Development Bank (AfDB) and Association of Power Utilities of Africa (APUA) assessments of power sector reforms in Africa. APUA conducted a study in 2008 on reforms in the African power sector, focusing on 19 countries. The 2008 study examined the reasons, drivers, and triggers underlying reforms; actors promoting the reforms; the design and implementation of reforms; the impacts on utility performance; and the key success and failure factors of reforms. The 2008 study was complemented by a Compendium of best practices (2009), drawn from nine country case studies. The case studies provide implementation guidelines in three categories: financing investments; improving efficiency; and designing legislative and regulatory frameworks to meet reform objectives.
