Screening Test Notices (STN)

SA Power Networks performs a non network options screening process for projects in accordance with Section 5.17.4 of the National Electricity Rules (NER) and the RIT-D Guidelines issued by the AER.
This process establishes whether or not any Non Network option is a credible alternative to the preferred network option to resolve a system limitation. If a credible option is identified then a Non Network Options Report is issued for public consultation.  If no credible option exists then a Screening Test Notice is published.
Further information on this process can be found in the Demand Side Engagement Document.
To be advised of the publication of a Screening Test Notice or other regulatory planning documents, please register your interest on the Demand Side Engagement Register.
