East Preston (EP) Conversion Stage 7 and Stage 8
This Regulatory Investment Test for Distribution (RIT-D) arises because the safety, reliability, age and condition of the East Preston Zone Substation and distribution assets is exposing customers to an increased loss of supply risk.
Notice of Determination
In accordance with Clause 5.17.4 of the NER and the AER’s RIT-D Application Guidelines, the first stage of the RIT-D process is to screen and determine if a non-network or stand-alone power system (SAPS) option is, or form a significant part of a potential credible option to address the identified need (i.e. network problem or limitation) on the network.
If a credible non-network or SAPS 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 or SAPS option can form a significant part of a potential credible option, then a Notice of Determination is required to be published in accordance with the requirements of clause 5.17.4, paragraphs (c) and (d) of the NER. Published below is JEN Notice of Determination for East Preston Conversion Stage 7 and Stage 8 project.
