The Commerce Commission will publish its final decision on Transpower's major capex project (MCP) proposal.

Transpower has published a draft version of the Security of Supply Assessment (SOSA) 2025.  

The annual assessment is used by market participants, policy makers and other stakeholders to inform risk management and investment decisions, including about development of new generation and transmission infrastructure. 

Transpower is seeking feedback on the draft 2025 SOSA to consider prior to the final publication which will be no later than 30 June 2025.  

Submissions close Tuesday 3 June 2025. The draft 2025 SOSA and information about how to provide feedback is on Transpower's system operator consultations page. 

The purpose of this green paper is to start the necessary discussion and debate among all electricity stakeholders around decentralisation and the future of our energy system.

The Electricity Authority Te Mana Hiko will use this feedback to help shape our regulatory thinking about what a more decentralised electricity system might look like for New Zealand, how this might benefit consumers, and what might be needed to gain these benefits.

Feedback is due by 5pm on 4 June 2025

The Electricity Authority Te Mana Hiko is encouraging all retailers to attend an information session next week to ensure they are ready for the new mandatory reporting that starts in August 2025.

Topics covered:

• How to prepare for the new data submission
• How to submit data via Secure File Transfer Protocol
• How to test the process (in advance of the first data submission on 31 August)
• Frequently asked questions

The session will be on Thursday 12 June 2.30-4.00pm, online or in person at the Authority's Auckland or Wellington offices.

The Electricity Authority Te Mana Hiko is seeking feedback on a proposal to amend Part 8 of the Electricity Industry Participation Code 2010 (Code) to address increased frequency variability in New Zealand’s power system. This is caused by the growing amount of variable and intermittent resources, including wind and solar generation.

Feedback on the proposal is due by 5pm, Tuesday 17 June 2025. Decisions will be shared in late 2025.

The Offshore Renewable Energy Bill is currently before select committee.

Transpower's 24 June System Operator Industry Forum has been extended to one hour to take participants through the outlook and how it forms a key part of the electricity industry’s security of supply forecasting and information framework. 

Transpower has released an Energy Security Outlook 101 document to help industry participants better understand its monthly assessment of energy security risk into the next two years.

The Electricity Authority Te Mana Hiko aims to release decisions on a working paper which aims to improve settings in relation to power purchase agreements (PPAs). Submissions were due 28 February 2025 and the full consultation was due for release in April (see above). 

The Energy Competition Taskforce is seeking feedback on a roadmap of 11 proposed actions to appropriately reward industrial consumers for the benefit their short-term demand flexibility brings to the power system.

As the level of intermittent electricity generation (wind and solar) in Aotearoa New Zealand increases and thermal generation reduces, the need for flexibility is becoming increasingly important.

Feedback is welcome on this proposed approach by 5pm, Thursday 26 June 2025.

Transpower has published a draft version of the Security of Supply Assessment (SOSA) 2025 in May.  

The annual assessment is used by market participants, policy makers and other stakeholders to inform risk management and investment decisions, including about development of new generation and transmission infrastructure. 

Final publication of the paper based n feedback will be no later than 30 June 2025.  

The Government's Review of New Zealand's electricity market, launched in November 2024, is expected to conclude in late June 2025.

The Electricity Authority Te Mana Hiko seeks feedback on two related proposals:

• Allowing customers to choose two different retailers; a retailer for consumption (load) and one for their generation
• Improving the efficiency and effectiveness of the consumer, distributor and metering equipment provider processes when a consumer switches power.

TheAuthority suggests these proposed changes will provide real benefits for consumers by allowing innovative retailers to compete for, and reward consumers for, their distributed generation. This should encourage investment in distributed generation, leading to an increase in regional resilience and overall system security.
