Jiji and Murembwe Hydroelectric Project. The Jiji and Murembwe Hydroelectric Project (, PHJIMU) is an project to build two hydroelectric power stations with shared infrastructure in the Bururi Province of Burundi.

Components

The project is being undertaken for REGIDESO Burundi, part of the Ministry of Hydraulics, Energy and Mines.
It includes building two run-of the river hydroelectric power plants in the Songa Commune of Bururi Province and the Buyengero Commune of Rumonge Province, in southern Burundi.
Contractors include CMC (Italy), ORASCOM (Egypt), KEC International (India) for the transmission lines and VINCI (France) for the associated stations.

Jiji Hydroelectric Power Plant 
The Jiji Hydroelectric Power Plant on the Jiji River will exploit a head height of  with a capacity of 32.5 MW.
The Jiji hydroelectric power station is near the point where the Jiji River joins the Murembwe River.
The Jiji dam is upstream, directing water along a supply conduit to a tunnel which leads to the forebay.
From there a penstock carries the water down to the power station.

Murembwe Hydroelectric Power Plant 

The Murembwe Hydroelectric Power Plant on the Murembwe River (Mulembwe River) will exploit a head height of  with a capacity of 17 MW.
The Mulembwe hydroelectric power station is upstream from the Jiji River junction.
It has a similar configuration, with a dam directing water through a tunnel to the penstock.

Transmission
A 110 kV power line runs  north from the Jiji station up the Mulembwe River to the Mulembwe station, where it is joined by a 110 kV power line from that station. The two lines run east  to the Horezo switchyard on RP 403 highway.
From there, lines run north towards Kabezi and Bujumbura, and southeast towards Bururi.
Other components include two 110 kV switching stations at the Jiji and Mulembwe hydroelectric plants, a 110/30 kV substation in Horezo, a 110/30/10 kV substation in Kabezi, extensions to existing substations, about  of 110 kV transmission lines, as well as distribution lines.

Finance

The total project cost was extimated at US$270 million.
The African Development Bank (AfDB) approved a grant of $22 million on 23 June 2014 in Tunis.
Other funding is supplied by the World Bank (US$100 million), the European Investment Bank (US$95 million), the African Development Bank ($US$22 million), the European Union (US$36.6 million), the Government of Burundi (US$14,3 million) and REGIDESO (US$2.5 million).

The project was initially scheduled for completion in December 2023.
In February 2024 Regideso announced that the Jiji station would be commissioned by 30 December 2024 and the Mulembwe station by 30 March 2025.
After cost overruns, effective May 2024 work continued at Jiji and Mulembwe under additional financing of US$102 million, of which the World Bank contributed US$50 million.

Events
The Burundian government started the project to build hydroelectric dams on the Jiji and Murembwe rivers in 2013.
Work began in 2020 after seven years of study.
Alain-Guillaume Bunyoni, prime minister of Burundi, visited the sites in  June 2021.
He said work on the access roads was going well, work had started on the Jiji River and would start soon on the Murembwe River.

In December 2022 there were torrential rains in Muheka colline, below the Nyakigo colline, but officials of the ORASCOM company said the Jiji Murembwe Hydroelectric Power Station was not badly affected.
The director general of REGIDESO Burundi asked ORASCOM to speed up the work.

In September 2022 Gervais Ndirakobuca, prime minister of Burundi, visited the two hydroelectic dams, where he observed cracks in the structures.
