Before energisation, Sondu supplied no power to Ndhiwa while the Muhoroni–Chemosit line carried loads as high as 68MW - levels considered stressful for system stability. After energisation, Sondu now supplies 27MW to Ndhiwa, while the load on Muhoroni–Chemosit has reduced to 40MW and flows between Muhoroni and Kisumu have dropped significantly, allowing electricity to be distributed more efficiently across the network.
