On 6 February 2019, the AER released its decision on Evoenergy's service standard event cost pass through application. Evoenergy proposed a positive pass through amount of $3.97 million ($2018-19) for the costs it incurred to comply with the Power of Choice reforms to the National Electricity Rules and the resultant changes to the market procedures administered by the Australian Energy Market Operator.

The AER determined that Evoenergy's application satisfied the definition of a service standard event and a positive change event under the National Electricity Rules. The AER approved a positive pass through amount of $3.97 million ($2018-19) to be recovered from network users in the regulatory years 2019-20 and 2020-21.
