The World Bank has approved an International Development Association credit of $455m for the Tanzania-Zambia transmission interconnector. The project aims to allow for regional power trade between the Southern African Power Pool (SAPP) and the nascent Eastern Africa Power Pool (EAPP) and increase power supply to underserved areas in both countries. The interconnector is the final segment of the Ethiopia-Kenya-Tanzania-Zambia regional transmission corridor that is being developed in phases.
