Transpower, as the system operator, is responsible for publishing an annual security of supply assessment. This assessment provides a ten-year view (2021 to 2030) of the balance between supply and demand in the New Zealand electricity system.
The assessment will use a range of scenarios and sensitivities. Scenarios are intended to provide a range of plausible futures for forecasting security of supply margins. Sensitivities allow us to explore uncertainties that will typically cover most, if not all scenarios.
The linked document below provides an outline of the scenarios and sensitivities that we intend to use for this year's 2021 assessment and invites feedback from market participants and stakeholders.
