Horizon Power provides the Region's urban centres with electricity, using independent diesel oil generators in all centres except Kununurra and Wyndham where hydro-electric power is used. 

A privately owned 30 MW hydro-electric power generation station is operational at the main Ord River Dam on Lake Argyle, 80 kilometres south of Kununurra. The station is the largest single contributor to renewable energy electricity generation in WA and provides electricity to the Argyle Diamond Mine and the towns of Kununurra and Wyndham.
