Regulatory Investment Test for Distribution projects
Establishing and upgrading powerlines, substations and other network infrastructure is vital to ensuring we provide a reliable electricity supply to our customers. Before committing to this type of work, registered participants and interested parties are invited to offer alternative solutions that satisfy the Regulatory Investment Test for Distribution (RIT-D).
Further information about how we're managing the network can be found in our Distribution Annual Planning Report.
Our requirements under the National Electricity Rules
Under the National Electricity Rules, if we're proposing to establish a new, large distribution asset to address a constraint, then we're required to:
- consult with Registered Participants, the Australian Energy Market Operator (AEMO) and Interested Parties on the anticipated limitation and options to address the constraint, within the time frame required for corrective action
- carry out a detailed economic cost effectiveness analysis of options to identify solutions that satisfy the Regulatory Test
- prepare a report for affected Registered Participants, the AEMO and Interested Parties which includes an assessment of all identified options, details of the preferred solution and the recommended action to be taken.
