KIKULETWA HYDROPOWER DEVELOPMENT FOR TANZANIA

COUNTRY: Tanzania REGION: Kilimanjaro CAPACITY: 17MW

SECSD performed the  task of Identification, Planning, Design and preparation of pre investment reports for a series of hydropower plants in four regions of United Republic of Tanzania for The International Bank for Reconstruction and Development (IBRD). On Kikuletwa river in Kilimanjaro region four  plants were identified and pre-investment reports prepared. 

The project is located on the Kikuletwa river in northern Tanzania at the foot of the world famous Mount Kilimanjaro near the  towns of Arusha and Moshi. The Kikuletwa river is a tributary to the  Pangani river and is fed by snow melt from the peaks of Mount Kilimanjaro which is a world famous tourist center.

PLAINS OF KILIMANJARO

SECSD was involved in planning new stations downstream of the closed Kikuletwa 1 power station till the confluence with Nyumba ya Munga reservoir. This reach was proposed earlier to be developed by JICA with a single stage development with 4km long canal but the implementation cost was very high. 

PLAN OF KIKULETWA WITH JICA DESIGN & SECSD ALTERNATIVE

SECSD engineers  in an innovative approach have reduced the proposed 4000m  water conductor system to only 450m  without any sacrifice in the power and energy output as conceived by JICA. This resulted in a substantial reduction of the implementation cost and construction period. As a result of investigations, two further sites for mini hydropower of 2MW each have been identified within the original reach contemplated earlier.  

LONGITUDINAL PROFILE OF KIKULETWA WITH PLANNING

This is shown in the river profile and plan above. The project is also suitable for private sector participation due to reduced cost.

One of the features involves a shaft type power house for stage three power house located in the bank of the river and standardized design for the stage-1 rehabilitation and stages 3 and 4. 

SHAFT TYPE POWER HOUSE

As the area is now supplied by grid which runs for nearly 300km from the Mtera power station, implementation will  reduce losses and demand of Moshi town will be entirely met by stage 3. 

The table on the right shows the projects in the cascade development. The stage-2 scheme cost was reduced from estimated US$ 40 million to US$12 million due to the reduction in water conductor system by 90%.
