2025 SOSFIP Review
December 2025
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.

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.

2022 Consultation
The Authority commissioned MartinJenkins to undertake an operational review of the 2021 dry year. This review included the dry year risk regime which includes the Security of Supply Forecasting and Information Policy (SOSFIP) and Emergency Management Policy (EMP). While the review found that the security of supply framework worked as intended and the dry year situation was managed, it highlighted areas of improvement for the SOSFIP and EMP.
After receiving the findings of the MartinJenkins report the Authority and Transpower initiated a review of these policies. The consultation proposed updates to the SOSFIP and EMP. Below is a link to the consultation paper.
