Due to the small size of most of their power systems, the cost of producing power in East Africa countries can reach US$0.20 per kilowatt-hour, which greatly increases the cost of doing business thus reducing competitiveness of firms. [...] Regional power trade will facilitate large-scale development of the region's cost-effective and clean energy sources – hydropower, geothermal power, wind and natural gas–, allowing all the countries of East Africa to benefit from these resources and share the costs. [...] The countries of East Africa have mandated the EAPP to coordinate investment in power generation and transmission projects for integration of the region’s power systems. [...] With funding from the AfDB and the European Commission, the EAPP Secretariat has prepared the first Regional Power System Master Plan (EAPP Master Plan) for the East African region, which was endorsed by the Governments of the EAPP member countries in 2011. [...] The proposed Regional Eastern Africa Power Pool Program will contribute to the development of the regional transmission network that is a pre- requisite for regional power integration.
