HoustonKemp - Regulatory treatment of large transmission investments - August 2020

On 17 November 2020, we published an open letter detailing the work we are undertaking to ensure our regulatory tools remain fit-for-purpose to effectively assess forecast expenditure for large transmission projects (identified as ‘actionable’ in AEMO’s ISP). This included the development of three guidance notes, and our initial views on topics we propose to cover in the guidance notes.

Alongside the open letter we published a report by HoustonKemp, which we used to inform our work program and initial views. HoustonKemp’s report scopes the challenges and reform options associated with assessing large transmission projects under the regulatory framework.

We invited stakeholders to input to our proposed work program, particularly to inform the development of our guidance notes.
