Description

The project consists of two components; namely:

a)Mombassa Nairobi transmission line and b)Electricity Access

A:Mombassa Nairobi transmission line

This is to be carried in three phases; namely:

Phase 1: This will involve:

(i) construction of 450 km 330 kV transmission double circuit line from Mombassa - Isinya,

(ii) construction of 25 km of double circuit 220 kV line connecting Isinya to existing Embakasi 220/132 kV substation and

(iii) construction of line bays at Rabai and Embakasi substations. This phase will enable KPLC to transfer power from Mombassa to Nairobi at 220 kV until the load demand on the line justifies 330 kV operation expected by 2015.

Phase 2: This will involve:

(i) construction of a 330/220/132 kV substation at Isinya,

(ii) constructing 34 km of 2x220 kV transmission lines to link the Isinya substation to Dandora existing substation and

(iii) Construction of line bays for the new Isinya Dondora 2x220 kV lines at Dandora. This will enable KPLC to transfer up to 500 MW from Mombassa to Nairobi between 2015 and 2019.

Phase 3: This will involve the construction of another double circuit line from Isinya to Dandora and line bays at Dandora substation. This will enable KPLC to transfer 750 MW from Mombassa to Nairobi.

B.Electricity Access

This component will consist of construction of high voltage transmissions line, construction of substations and distribution lines to rural areas including installation of distribution transformers, MV distributions lines service connection and meters.


Objectives

The objective of the project is to enhance the socio economic development of Kenya by reinforcing its transmission system and increasing the electricity access in the country. The project, when completed, will contribute towards reducing the power losses and increasing access of electricity in both rural and urban areas.


Rationale

Currently the existing transmission infrastructure between Mombassa and Nairobi comprises of a 450 km 132 kV line and a 600 km 220 kV line which links Nairobi through Kiambere hydropower station. This network work has a transfer capacity of 56 MW. This capacity will be outstripped by the end of the year 2009 when the installation of the committed thermal plants in Mombassa is completed. Based on the forecast demand and the generation planned, it is imperative that the Mombassa Nairobi is implemented by the year 2010.

Besides the demand in Kenya, the line is expected to supply the demand in Tanzania after the construction of the planned Nairobi-Arusha Transmission line thus allowing power exchange between the two countries.

The project will also extend power to rural and semi urban areas where electricity will contribute the development of the areas through commercial activities and industrial development. The project will therefore contribute to poverty reduction which is a central of the Bank.

The project conforms to Bank's strategy of promoting infrastructure development and regional integration.


Benefits

The project will provide benefits to the population in Kenya by providing electricity necessary for commercial and industrial development. Other sectors of economy such as agriculture and tourism will also benefit from the project. Consultants and contractors will also benefit through contracts that will be signed with KPLC. Power trade between Kenya and Tanzania will also be enhanced thus benefiting the two companies and the citizens of Tanzania.
