Project General Description

The 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 EthiopiaKenya transmission system through the Isinya – Suswa 400 kV line, is part of the Eastern Africa Electricity Highway, with a transfer capacity of 2000 MW. As such, it will be the major link for power transfer between the Eastern Africa Power Pool and countries in the North such Sudan and Egypt. Completion of the line is expected in early 2017.

Project Objectives

The ultimate development objective of the project 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 includes a rural electrification programme which consists in providing electricity access to about 21 villages (16 in Tanzania and 5 in Kenya) located within 20 km from the T-line and which are not currently connected to the grid. The project will entail the connection of the targeted households to the grid as well as the installation of pre-paid meters. This will enable a population of around 198,000 people (128,000 in Tanzania and 70,000 in Kenya) to have access to electricity and benefit from improved education and health services. Among the villages to be electrified in Tanzania included rural area around Babati Katesh, Giting, Endesh, Mgori and Ngimu. In Kenya, most of the villages along the line electrified with limited number of customers. Under the project financing the existing distribution transformers shall be exploited to the maximum through the extension of the low voltage network to reach around people located in the vicinity of these transformers and also with installation of new distribution transformers and low voltage lines.
