Project General Description

This project involves the construction of a high voltage alternating current (HVAC) 400 kV transmission line (T-line) with a total length of 507.5 km, of which about 414.4 km are located in Tanzania and 93.1 km in Kenya. In Tanzania, the project includes the construction of a 400 kV substation in Arusha and the extension of the existing Singida substation. In Kenya, the project does not involve any works related to substations. Indeed, the substation outgoing bay in Isinya is part of the existing Nairobi Reinforcement Project which is currently under construction. The proposed interconnection line, to be connected to the Ethiopia-Kenya transmission system through the Isinya – Suswa 400 kV line, is part of the Eastern Africa Electricity Highway with a transfer capacity of 2,000 MW. As such, it will be the major link for power transfer between the Eastern Africa Power Pool and countries in the North such as Sudan and Egypt. Completion of the line is expected in early 2017.

Project Objectives

The project's ultimate development objective is to improve the supply, reliability and affordability of electricity in the Eastern Africa region through cross-border exchanges of cheap and cleaner surplus power from neighboring countries. This project, through promotion of power trade at the regional level, will contribute to Eastern Africa’s socioeconomic transformation. Indeed, the project will help to improve the supply of electricity in Tanzania in the short to medium term with imports from Ethiopia. The project will contribute to: (i) improved power supply in both countries and in the East African region in general and; (ii) reduced operation costs of energy production. The project will help both countries to replace some of the high cost thermal energy production with cheaper hydropower, hence reducing Greenhouse Gas (GHG) emissions.


The project's direct beneficiaries are households, businesses, and industries in communities located in both countries. The line is expected to benefit countries in North, East, and Southern Africa through interconnections between the EAPP and SAPP hence facilitating power trade in the two sub-regions.
