AER – Preliminary position paper – Transgrid – System Strength Project 2026–31 – June 2026

On 30 June 2026, we published our preliminary position paper for Transgrid’s System Strength Project revenue determination for the 2026–31 regulatory period. 

Our preliminary position paper follows consultation on Transgrid’s revenue proposal and provides an early indication of our assessment. Our preliminary positions are informed by stakeholder submissions and highlight areas of Transgrid’s proposal which we are likely to not accept or consider would benefit from focused feedback from stakeholders. Our assessment identifies risk and labour and indirect costs as the two key focus issues for stakeholder consideration and feedback.
