Tanzania's Julius Nyerere Hydropower Dam Operating at 40% Capacity Due to Transmission Issues
The Julius Nyerere Hydropower Project is currently functioning at only 40% of its capacity due to national transmission system bottlenecks. Urgent infrastructure improvements are essential for optimizing energy delivery in Tanzania's growing market.

Tanzania's Julius Nyerere Hydropower Project (JNHPP) is operating at 40% of its 2,115 megawatts capacity, limiting actual supply to approximately 800 megawatts due to transmission constraints. The Tanzania Electric Supply Company Limited is developing two major 400kV transmission lines, with the Chalinze-Dodoma line reaching 69.9% completion and expected to be finalized by September 30, 2026.
The project has attracted criticism for underutilization and has been highlighted in audit reports for insufficient testing of machinery post-completion. Experts emphasize that public-private partnerships are vital for overcoming energy challenges.
Additionally, Tanzania aims to increase energy generation to 70,000 megawatts by 2050 to support its economic goals. Without significant improvements, the country risks failing to meet future energy demands.
