In mid-1998, Tanesco commissioned a feasibility study of Rumakali that now requires technical, economic, environmental, and financial updating before the utility can recommend it for implementation.
The Rumakali site, 85 kilometers west of Njombe, was identified in a 2008 master plan as one of the next two least-cost hydropower stations to be developed in Tanzania. Other sites that have been studied include 21-MW Mandera, 118-MW Masigira, 165-MW Mpanga (HNN 8/31/06), 358-MW Ruhudji (HNN 8/8/08), 900-MW Stieglers Gorge (HNN 5/23/08), and 47-MW Upper Kihansi. Total hydropower potential is estimated to be at least 4,500 MW, the World Bank said.
Tanesco seeks consultant services including a review of all existing studies of Rumakali, optimization of project layout and field work, preliminary specifications, capital cost estimates, operations and maintenance cost estimates, construction schedule, analysis of associated environmental and social impacts, degradation and sedimentation, and other downstream issues. It also seeks review of hydrology, integrated water resources management, and stakeholder consultations. The consultant also is to evaluate alternative transmission line options.
