On 23 August 2013, the AER released its final Regulatory Investment Test for Distribution (RIT-D) and accompanying RIT-D application guidelines. The RIT-D establishes consistent, clear and efficient planning processes for distribution network investments in the national electricity market.
From 1 January 2014, distribution businesses must assess applicable network investments under the RIT-D. The RIT-D replaces the former regulatory test.
On 18 September 2017, we published amended RIT-D guidelines as part of the transitional arrangements under the Australian Energy Market Commission’s (AEMC) replacement expenditure planning arrangements rule change (“repex rule change”).
The 2013 RIT-D application guidelines have been superseded. Please refer to the 2017 RIT application guidelines for the latest information.
