The corruption watchdog has been called in to WA’s state energy supplier Horizon Power over alleged serious misconduct.
Horizon supplies power to about 100,000 residents and 10,000 businesses across regional Western Australia.
The government-owned entity informed staff this week that an employee and contractor had been arrested and charged.
The ABC understands WA police officers and Corruption and Crime Commission (CCC) staff were at Horizon offices as part of the investigation.
Horizon said it reported suspected misconduct to the CCC last year, and had been cooperating with the investigation.
“Horizon Power can confirm that no customer data has been impacted by the alleged misconduct,” the entity said in a statement to the ABC.
The statement said it could not confirm any further details as the investigation was ongoing.
Last year the company was accused of overcharging customers for power in the state’s Kimberley and Pilbara.
The then-energy minister Mike Nahan dismissed calls for an inquiry.
It is not clear if the fresh charges are linked to previous billing issues at the utility.
