Electricity Demand and Generation Scenarios (EDGS) 2023 consultation

Submissions closed: 06 June 2023, 12pm

We undertook a consultation over May and June 2023 on a set of draft assumptions about the future state of the electricity system. These assumptions will be used to produce our regular Electricity Demand and Generation Scenarios (EDGS) publication.

What we sought feedback on

MBIE prepares a range of possible scenarios called EDGS that explores potential future electricity demand and generation in New Zealand. These scenarios are used by the Commerce Commission to assess Transpower’s planning proposals for future capital investment in the electricity transmission grid.

In this consultation, we sought feedback from stakeholders to ensure that the potential scenarios presented, and resulting modelling, accurately reflect the potential pathways that the electricity sector could take. The consultation was open between Thursday 4 May and Tuesday 6 June (previously Monday 22 May).


MBIE received 19 submissions from stakeholders representing a range of backgrounds. We will be releasing a compiled next steps document outlining the stakeholder feedback, our response, and the next steps.

Submitters gave permission for their submissions to be published. Redactions have been made in accordance with the Privacy Act 2020. These can be accessed from the link below.
