This run-of-river hydropower plant is located in Isingiro District in Southern Uganda on the border with Tanzania.
At appraisal stage, the Project had a planned installed capacity of 16 MW and was expected to deliver 115 GWh of output annually. At the end of 2018, the Developer advised that the name plate on the plant would instead be 14 MW, but that updated energy modelling indicated an expected two percent increase in power output annually. Until potential implications of the design change for the GET FiT Programme have been clarified and the design change materialises, the Project will continue to be reported at 16 MW.
Having resolved the transboundary issues in executing a bilateral agreement between the Governments of Uganda and Tanzania in 2017, the Project experienced a further major setback in Q1 2018. The EPC Contractor, which had initially mobilised to site during Q4 2017 and commenced site establishment, was subsequently replaced early during Q2 2018 for commercial and performance reasons. A split EPC contract was adopted instead, with the replacement EPC Civil Contractor being awarded a Limited Notice to Proceed during Q2 and the original electromechanical subcontractor being awarded a Notice to Proceed as the EPC Electromechanical Contractor, also during Q2.
To minimise delays to the Project during replacement of the EPC Contractor, the Developer continued with construction of the camp facilities. The replacement EPC Civil Contractor subsequently mobilised to site during Q3, undertook further ground investigation works and design reviews, and largely completed mobilisation to site. The powerhouse and intake were relocated further inland as a result of the design review, and excavation of the powerhouse foundations were well underway by the end of the year. Design modifications to the dam arrangement, spillway gates and fish pass were also being considered.
Despite the delays, the revised commercial operation date for the Project had been brought forward to early Q3 2019, approximately two months earlier than the programme of the previous EPC Contractor.
