Power Transmission

By end of June 2017, some 745 km of High Voltage (HV) transmission lines had been laid, evacuating power from various points of generation across the country, as well as facilitating regional interconnectivity. These are mainly 110kV and 220kV transmission lines. The 70kV lines previously running through Birembo-Musha to Kabarondo substation that existed till 2013, were upgraded to 110 kV to improve network reliability and power supply stability amidst the country’s changing power demand profile.  Meanwhile, the country directed investments towards more advanced transmission infrastructure, 220kV since 2015, with the construction of 93.5 km of 220kV Mirama-Shango transmission line, to support regional power trade from Ethiopia, Kenya and Uganda in future as and whenever needed. In total, 6 high voltage transmission lines (193.5 km) were completed in the last 7 years from 2010 to 2017. Some other transmission lines are still under implementation to beef-up the existing network, including 119 km of 110 kV transmission line: Rulindo – Ngarama – Gabiro – Musha, expected to be completed in 2018.

Planned transmission infrastructure in the next few years include:

·    220 kV Transmission line: Mamba – Rwabusoro – Bugesera. 53 km, expected to be completed in 2019 to evacuate power from the Peat-Power Plant underway in  Gisagara district.

·         220 kV Transmission line:  Rusumo – Bugesera – Shango.  119 km expected to be completed in 2019, to evacuate power from  Rusumo Regional Hydro Power Plant.

·         220 kV Transmission line: Karongi – Kigoma – Rwabusoro.  74km, expected to be completed in 2019 to evacuate power from production points in the Western Province

·         220 kV transmission line: Kigoma – Gisagara - Gitega (Burundi Border). A 62 km line to be completed in 2019 to strengthen the netweork in parts of Gisagara and Huye districts and potential power exchange between Rwanda and Burundi.

·         220 Kv transmission line: Karongi – Kamanyola. A 92.8 km line planned to evacuate power from  Rusizi III regional Hydro Power plant.

·         110 Kv transmission line: Mukungwa – Nyabihu. A 23.3 line  planned to be completed in 2019 to enhance network strengtening in parts of Nyabihu and neighbouring areas. 

·         110kV single circuit Jabana I - Mt.Kigali - Gahanga 

·         110kV single circuit Gasogi – Ndera- KSEZ -Ndera SS: Improvement of Substations and Distribution Network

 

Currently we have 20 substations that are operational around the country as transmission lines are being laid out countrywide so as substations.
