Nyamwamba II Hydroelectric Power Station, is a 7.8 megawatts mini-hydroelectric power station, that was commercially commissioned in March 2022 in Uganda. [1] The run of river mini-hydroelectric installation is owned and was developed, between October 2019 and March 2022, by Serengeti Energy Limited, a Kenyan independent power producer (IPP), which was formerly called responsAbility Renewable Energy Holding (rAREH). [2] The energy generated here is sold directly to the Ugandan electricity transmission parastatal company, Uganda Electricity Transmission Company Limited (UETCL), under a 20-year power purchase agreement (PPA). The power is integrated into the Ugandan national electric grid. [1]

Location

The power station is located in the village of Kilembe, across the River Nyamwamba, in Kasese District in the Western Region of Uganda. This is in the foothills of the Rwenzori Mountains, close to the border with the Democratic Republic of the Congo. Nyamwamba II HPP straddles the Nyamwamba River, upstream of the 9.2 megawatts Nyamwamba I Hydroelectric Power Station, also owned an operated by Serengeti Energy Limited. [3]

Overview

The power station is a run of the river mini-hydropower installation, with installed capacity of 7.8 megawatts. The power station is owned by Serengeti Energy Limited, an IPP based in Nairobi, Kenya. [1]

The engineering, procurement and construction (EPC) contractor for Nyamwamba II HPP was a consortium comprising South Asia Energy Management Systems LLC (SAEMS), based in Sri Lanka, who were responsible for civil works, and Andritz AG of Austria, who were responsible supplying and installing the electric generators and other electromechanical installations. Zutari Engneering, based in South Arica, was the Owner's Engineer. [1] [2]

Construction costs and funding

The construction costs are reported to be US$22 million. The table below illustrates the sources of funding for this renewable energy project. [1]

Financing Sources For Nyamwamba II Hydroelectric Power Station
RankName of LenderNotes
1Emerging Africa Infrastructure Fund (EAIF) [1]
2 Regional Liquidity Support Facility (RLSF) [1]
3African Trade Insurance Agency (ATI) [1]
4Serengeti Energy Limited (SEL) [1]

In May 2022, Afrik21.africa reported that Emerging Africa Infrastructure Fund (EAIF), lent Serengeti Energy US$10.6 million, to be repaid over 17 years. As a result of that loan, Serengeti was able to retire the construction loans, leaving EAIF as the sole lender to the project. [4]

Construction timetable

Construction started in October 2019 and commercial commissioning was effected on 17 March 2022. [1] [2] [5]

Other considerations

Nyamwamba II HPP created 205 jobs during the construction phase and employs 25 people during the operational phase. It provides electricity to an estimated 161,000 Ugandan customers. The green energy it produces helps reduce carbon dioxide emissions by 18,000 tonnes annually. [1] [2]
