On 6 February 2019, the AER released its decision on Evoenergy's service standard event cost pass through application. Evoenergy's application relates to the costs that it will incur in 2018-19 to comply with its new vegetation management and electrical infrastructure inspection responsibilities, which took effect from 1 July 2018.

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 $2.40 million ($2018-19) to be recovered from network users in the regulatory years 2019-20 and 2020-21.
