Two former ActewAGL contractors skimmed more than $12,000 from customer accounts to pay for a trip to Las Vegas.
However, Taylor Jade Geoghegan, 21, and Jessica Kate Anderson, 29, instead received jail sentences for the fraud.
In the ACT Magistrates Court on Monday, Geoghegan was ordered to repay the power company $6065.
Magistrate Glenn Theakston also sentenced Taylor Jade Geoghegan, 21, to eight months jail, to be fully suspended on signing a good behaviour order, and 160 hours community service.
Geoghegan and Anderson had been customer service contractors at ActewAGL when they hatched the plan last year.
The fraud involved the pair identifying accounts in credit, before saving the details.
Anderson would then call the electricity utility to request the money be refunded and have the cash transferred into accounts she controlled.
In one instance, Geoghegan borrowed a colleague's driver's licence and set up a bank account in the person's name to have the money sent there.
Anderson would then withdraw the cash and split the proceeds with Geoghegan.
The pair stole $12,130.59 over a two month period between April and June, 2017.
The offenders resigned from the recruitment service they worked for in May, and bought plane tickets to Las Vegas for December.
But the fraud was detected Geoghegan and Anderson were arrested in July, 2017.
Geoghegan pleaded guilty to five counts of fraud and one charge of intentionally providing misleading information and appeared for sentence in the Magistrates Court on Monday.
The court heard Geoghegan had attempted to deflect blame to her co-offender, but had displayed some insight into the offending and the impact it had on others.
Mr Theakston said the crime appeared to have been partially motivated by malice as a "spiteful attack on ActewAGL".
However, he said the goal had been to pay for an overseas holiday.
He accepted that the offender had no other criminal convictions and, as the younger of the women, she had been enabled, encouraged and aided by Anderson.
Mr Theakston said it had been Geoghegan's youth which had saved her from time behind bars.
The magistrate instead sentenced her to a suspended jail sentence and community service order.
Anderson was sentenced in February after pleading guilty to six counts of obtaining property by deception, two attempts at the same, one joint commission and one anti-money laundering.
She was sentenced to eight months jail, back dated to January 21 to account for time she had already spent in custody.
It was ordered she spend two months behind bars, before her release on a six month good behaviour order.
She was released in March.
