The TAZA Electricity Line Project

The TAZA Electricity Line Project (Tanzania-Zambia Transmission Interconnector) is a key energy infrastructure initiative designed to enhance electricity trade and grid reliability between Tanzania and Zambia, supporting regional power integration in Southern Africa. Here’s what you need to know:

Overview
– Official Name: Tanzania-Zambia Transmission Interconnector (also part of the Southern African Power Pool [SAPP]).  
– Purpose: Enable bidirectional electricity trade, improve grid stability, and increase renewable energy sharing.  

Project Components
1. High-Voltage Transmission Line 
   – Length: ~300 km (from Iringa, Tanzania, to Mbala, Zambia).  
   – Voltage: 400 kV (high-capacity for long-distance transmission).  
   – Route: Connects Tanzania’s Singida substation to Zambia’s Pensulo substation.  
2. Substations & Grid Upgrades  
   – New substations in Iringa (Tanzania) and Mbala (Zambia).  
   – Reinforces existing infrastructure in both countries.  
3. Regional Integration 
   – Part of the Zambia-Tanzania-Kenya (ZTK) Power Interconnector, a broader plan linking
Eastern and Southern Africa. 

Benefits
– Energy Trade: Tanzania can export excess hydropower (e.g., Julius Nyerere Dam) to Zambia,
which faces shortages.  
– Renewable Energy Sharing: Facilitates solar/wind power exchange.  
– Economic Growth: Supports mining and industrial sectors in both countries.  
– SAPP Integration: Strengthens the Southern African Power Pool, reducing reliance on
South Africa’s Eskom.
