Police have charged two men connected to Horizon Power after a damning Corruption and Crime Commission report was tabled in parliament last week.

The CCC began investigating staff at Horizon in March 2016, before launching a joint investigation with police in September 2017.

A 47-year-old man from North Coogee has been charged with four counts of corruption and a 43-year-old Salter Point man has been charged with four counts of fraud.

The CCC report found a Horizon Power technology manager invoiced a company he owned to pay down a credit card debt and had employed his wife as a contractor for the business and charged Horizon Power $700 a day.

In a media statement issued by the CCC after it tabled the report, it warned: "The conduct detailed in the report is not confined to this single incident or work place, but may be widespread throughout the community."
