Description

The arrangement of the Project is described in the Feasibility Study and was conceived in order to fully develop the cascade of the Ruzizi River in concert with the existing Ruzizi I and Ruzizi II projects and the proposed Ruzizi IV development. The Project develops a gross generating head of about 115 m by combination of a diversion dam and a headrace tunnel. The diversion dam impounds a small reservoir that will provide short term storage for use in hourly regulation of the generating output. The power station proposed will be comprised of three turbine-generator units with a total installed capacity of 147 MW. Each turbine is designed for a maximum flow rate of 50m3/s giving a total plant discharge of 150 m3/s. The annual power produced will vary depending on the water level in the reservoir and the number of units in operation but is expected to be 650 - 710GWH.

To facilitate power evacuation of power,

(i) three transmission lines of approximately 90km each and corresponding terminal substation equipment are included,

(ii) a coordinating center to be built at Kamanyora substation will provide water management for the entire Ruzizi cascade,

(iii) Access Scale up: connection of villages and towns in South East region,

(iii) Scaling up access to electricity and reinforcement of the distribution grids in Easter DRC, Burundi and Rwanda, in total 350,000 new connections are planned,

(iv) Capacity Building, Technical Assistance Project Management


Rationale

¢Project aligns with the Bank's public and private sector energy development strategy; financing clean renewable energy projects, to increase access to energy, to reduce dependence on carbon intensive power generation and to use domestic energy resources. ¢Ruzizi III is priority project of PIDA and promotes Eastern Africa grid power market integration, and as it is positioned strategically at the tail end of the greater Eastern Africa grid, its role in power system stability and voltage support is extremely critical. ¢It will also save at least 120,000tons CO2/year of emissions for the three countries combined. ¢It will double the current generation capacity of Burundi, and East DRC, and increase that of Rwanda by 50% allowing electricity connection to additional 350,000 households, institutions, commercial and industrial customers, and stabilizing power supply in the Great Lakes Region. ¢Further, it will increase EGL's capacity to develop and manage hydropower projects on the Ruzizi cascade. ¢The Project is evaluated to have a strong social development impact within and beyond the project region.


Benefits

The most important benefit from the plant will be an annual power production of 650GwH, which can roughly supply 350,000 households. The power will be distributed to households, commercial entities, industries and institutions in the three countries. Further the project is designed to increase EGL's capacity to develop and manage new hydropower projects on the Ruzizi river. It is envisaged that the river can accommodate at least five hydropower plants with a combined generation capacity of 650MW.
