AER seeks views on its proposed guidelines to make the ISP actionable

The Australian Energy Regulator (AER) has published draft Guidelines to make the Integrated System Plan (ISP) actionable. These draft guidelines were released on 15 May 2020 and include:

  • a new cost benefit analysis guideline
  • a new forecasting best practice guideline
  • updates to existing regulatory investment test for transmission (RIT–T) instrument
  • updates to existing RIT‒T application guidelines.

The draft guidelines are part of the new ISP framework, as implemented through changes to the National Electricity Rules made on 2 April 2020 (effective 1 July 2020). They seek to provide certainty, transparency and accountability for AEMO, transmission businesses, and stakeholders to promote efficient investment in electricity services for the long term interests of consumers.
