Submissions and cross submissions are now closed.
Earlier this year we invited feedback on an Issues paper to inform the scope of this SOSFIP review. The feedback we received confirmed general agreement that a SOSFIP review is timely. The electricity sector is evolving rapidly, with increasing reliance on intermittent renewable generation and heightened risks to natural gas supplies. This review aims to ensure the SOSFIP remains fit for purpose, supporting security of supply in New Zealand’s power system.
The draft amendment proposal reflects feedback from our earlier Issues Paper, and addresses key topics including risk curve assumptions, capacity risk assessment, and access arrangements for contingent storage.
Feedback received during this consultation will inform the final amendment proposal that Transpower, as System Operator, submits to the Authority later in 2025.
We hosted a special System Operator Industry Forum to present the draft SOSFIP amendment proposal, watch the forum here SOSFIP Consultation Information Session 21 Oct 2025.

Our Response
We completed consultation in late 2025 on a draft proposal to amend the Security of Supply Forecasting and Information Policy (SOSFIP). The proposed changes aim to address evolving market conditions as the electricity system accelerates its transition towards increasing dependence on intermittent renewable generation, and risks to the availability of natural gas supplies to substitute for hydro generation during extended dry periods have increased.
Key amendments include improved forecasting tools, enhanced risk communication, updated contingent storage buffer settings, and expanded system risk considerations. Stakeholders broadly supported the changes, emphasising the importance of clarity, transparency, and timely information. The amendments are set to be implemented before Winter 2026, with minimal costs expected.
We understand the Electricity Authority Board is likely to consider whether to approve our proposed SOSFIP amendment at its meeting in February.
A full history of SOSFIP reviews is available here.

Broader issues, such as contingent storage access policy, were identified as outside the scope of this review and referred to the Electricity Authority for further evaluation.
