MTAMBO HYDROPOWER DEVELOPMENT FOR TANZANIA

COUNTRY: Tanzania REGION: Rukwa CAPACITY: 3MW 
Click to go back to Main Page  CLIENT: IBRD ENERGY: 19 GWh

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 World Bank. On Mtambo river in Rukwa region three  plants were identified and pre-investment reports prepared.

The project area is located in the western part of Tanzania in Rukwa region. Mpanda is the only town in the region apart from the regional capital Sumbawanga. Electricity in Mpanda is supplied by a diesel set operated by TANESCo. 

SECSD was involved in location of an alternate source of power for supply to Mpanda. After a thorough study of topographic sheets of the region, the Mtambo river was selected for identification of prospective sites.

The Mtambo is a tributary to the major river Ugalla which drains the heartland of Tanzania and eventually joins the Malagarasi. The study demonstrates how to develop similar tributaries and hence exploit the hydropower potential of the entire basin. As per the proposed development about 10MW could be obtained in phased development.

PLAN OF MTAMBO  WITH PLANNING

The schemes identified on the Mtambo are shown. Some of the stages are proposed to provide storage only though at a later stage they could provide power also.

PROFILE OF MTAMBO WITH PLANNING

The plan of the scheme selected for supply to Mpanda is shown. A simple layout utilizing the flows of Sanda was developed. The power house will be a conventional standardized vertical Kaplan unit. Transmission route was planned and will be along the road to Mpanda.
