Indicative technical requirements for generation and storage connections discussion paper

EnergyCo has published a discussion paper outlining our indicative technical requirements for generation and storage projects seeking to connect to the New England Renewable Energy Zone (REZ).

Why we’ve released this paper

The New England REZ will bring together new solar, wind and storage projects, supported by new transmission infrastructure. To ensure the REZ operates safely, reliably and efficiently, We're developing a set of REZ access standards – technical requirements that generator and storage projects may need to meet when connecting to REZ network infrastructure.

While access standards will not be consulted on until later in 2026, we're providing early guidance now so industry proponents can plan ahead. The discussion paper outlines our indicative position on a range of technical requirements, including areas where they may differ from the standards normally applied under the National Electricity Rules.

What the paper covers

The discussion paper provides:

  • EnergyCo’s early views on a subset of technical requirements for solar, wind and battery projects
  • information on where we are proposing to apply minimum or automatic access standards
  • areas where requirements may differ based on the unique characteristics of the New England REZ
  • details on which requirements still need further power system studies before they can be defined
  • next steps on how access standards for New England REZ will be developed.  

These indicative requirements are not final and will continue to evolve as REZ planning progresses.

Who we want to hear from

We welcome feedback from:

  • renewable energy generation and storage proponents
  • network operators and technical specialists
  • stakeholders participating in the New England REZ procurement process.

Your feedback will help refine the approach and support the development of draft REZ access standards in 2026.

Feedback

Feedback is open until 6 February 2026 and can be emailed to [email protected]  

Generation and storage consultation paper

In August 2025, EnergyCo published the New England Renewable Energy Zone Generation and Storage Consultation Paper, outlining proposed design features under consideration for a potential access scheme, a connection assets model and the provision of system strength for the New England REZ.

We are currently reviewing submissions to inform the next stages of detailed design, shaping how we approach generation and storage for the New England REZ.

Webinar

We hosted a public webinar on 26 August 2025 to provide stakeholders with an overview of the paper and key design questions, and provide an opportunity to participate in a Q&A.
