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.
