Guidelines to make the integrated system plan actionable

On 15 May 2020, we published draft guidelines to make the ISP actionable, along with an explanatory statement and fact sheet. The draft guidelines include:

• a new 'cost benefit analysis guideline', which will apply to the Australian Energy Market Operator (AEMO) and regulatory investment test for transmission (RIT-T) proponents
• a new 'forecasting best practice guideline', which will replace the current interim forecasting best practice guideline and will apply to AEMO
• updates to the existing RIT-T instrument and application guidelines, which apply to RIT-T proponents

To assist stakeholders in viewing the changes we are proposing to the RIT-T application guidelines for non-ISP projects, we have also published a marked-up version of the draft against the current RIT-T application guidelines. Marked up versions of the forecasting best practice guidelines and RIT-T instrument are also available on request.
