POWER TRANSMISSION

Rwanda’s transmission network is of 3 main voltage levels; 70kV, 110kV and 220kV transmission infrastructure. By end of March 2017, some 744.7 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. Of the total network laid so far, 480.4 km (64.5%) are 110kV and 264.3 km (35.5%) are 220kV transmission lines.

The remaining 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.
