January 4, 2021

Developers: Tanzania Electric Supply Company Limited (TANESCO) and ZESCO Limited


Project details and status: TAZA is part of the larger Zambia–Tanzania–Kenya (ZTK) project, which aims to link the Southern African Power Pool (SAPP) with Eastern Africa Power Pool (EAPP).


ZTK is divided into two sections, namely, the TAZA and the Kenya–Tanzania Power Interconnector Project (KTPIP). Overall, the ZTK project will involve the construction of 2,302 km of 400 kV double-circuit lines and 373 km of 330 kV single-circuit lines at an estimated cost of USD1.4 billion.


TAZA entails the construction of the 298-km-long, 330 kV Kabwe–Pensulo line; the 200-km, 330 kV Pensulo–Mpika line; the 200-km, 330 kV Mpika–Kasama line; the 212-km, 330 kV Kasama–Nandoke line; and the 14-km, 400 kV Nakonde–Tuduma double-circuit line in Zambia.


TAZA is estimated to cost USD605 million and is being jointly funded by the World Bank, Agence Française de Développement (AFD) and the European Commission (EC).


In 2019, on the Zambian side, construction works were started for the Kasama–Nandoke line and are expected to be completed in 30 months.


In June 2020, AFD signed a financing agreement with TANESCO for providing EUR100 million through a concessional loan for the project.


In November 2020, TANESCO invited bids for seeking individual consultancy services for assistance in procurement activities under TAZA.


In December 2020, TANESCO commenced construction on the Tanzanian side of the project. The utility also signed a financing agreement with AFD for receiving the USD31.5 million in the form of a grant.  


The KTPIP is also under construction. The entire ZTK project is anticipated to be commissioned in 2021.
