On 14 December 2018, we published version 3.0 of the application guidelines for the regulatory investment test for transmission (RIT–T) and the regulatory investment test for distribution (RIT–D). We also published a fact sheet and final decision to explain how stakeholder input has informed the improvements we have made.
