Non-network options Screening Notice
In accordance with Clause 5.17.4 of the NER, the first stage of the RIT-D process is to screen and determine if a non-network 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 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 screening notice is required to be published.
