Brighter Africa: The growth potential of the sub-Saharan electricity sector builds on the McKinsey Global Institute’s 2010 report Lions on the move: The progress and potential of African economies, which focused new attention on Africa’s accelerating economic growth. This report, its scenarios, and its supporting model are not intended to forecast the future but to lay out the opportunities and the challenges. We also offer examples from our own experiences in power-sector development across Africa and across the globe. We believe that subSaharan countries will witness a true economic breakthrough if they are able to successfully promote massive development of the power sector. If this report helps speed this breakthrough, then we will have achieved our goals.
