This Regulatory Investment Test for Distribution (RIT-D) arises because of the condition of the No.3 transformer, which is one of the three 22/6.6kV transformers at FF, is deteriorating and at risk of failure, which poses both a safety and a reliability risk. 

Non-network options report

In accordance with Clause 5.17.4 of the NER, the first stage of the RIT-D process is to screen for and determine if a non-network option is credible, or can form a significant part of a potential credible option to address the identified need (i.e. network problem or limitation).

If a credible non-network option is identified then a non-network options report is required to be published for consultation. However if it has been investigated and determined that no non-network option can form a significant part of a potential credible option, then a non-network options notice of determination is required to be published.
 
Published below is Jemena’s non-network options notice of determination for Fairfield Zone Substation (FF) Transformer No.3 Condition and 4th Bus project.
