Power line to link southern and East Africa by 2025

Tanzania is building a new transmission line to export 300 MW of electricity to Zambia.This move will address Zambia's load-shedding issues and improve Tanzania's domestic electricity infrastructure.The 300 MW supplied to Zambia will cover nearing half of its current electricity deficit of approximately 750 MW. The Tanzania Electric Supply Company (Tanesco), the country’s power utility, confirmed that the 400 kilovolt (kV) Tanzania-Zambia line will be completed in November 2025. The project seeks to connect  at least 30 nations in the Eastern Africa Power Pool (EAPP) with the Southern Africa Power Pool (SAPP).

• Electrical substations, including in Mainger Town, will be built to manage overloads, enhancing the existing transmission line.

• The Tanzania-Zambia transmission line's successful completion will boost Tanzania's economy, create export opportunities, and necessitate future planning for increased electricity demand.

• Zambia  is also exploring geothermal energy with Kalahari GeoEnergy developing the Bweengwa project aiming for 12 MW by 2030, starting with a 20 kW demonstration plant and upgrading to 150 kW by January 2025.

• Since 2011, Kalahari has identified the Kafue Rift for geothermal energy, estimating 5-7 MWe capacity, aiming to provide climate-resilient baseload power, and inviting investments to overcome high upfront costs for drilling and infrastructure.
