Transpower in its role as the System Operator is consulting on its coordination of Low Residual (or tight capacity) Situations on the power system. These situations occur when the remaining offered capacity (Residual) for a given trading period drops to a level that increases the risk of a grid emergency and potential demand management.
We constantly monitor forward schedules to anticipate Low Residual Situations and communicate with industry participants to avoid potential grid emergencies. The current Low Residual threshold is set at 200 MW. This threshold signals an increased risk of shortfall in real-time and provides information on potential actions that could reduce this risk.
Feedback is sought on the threshold, process, notices, and communications used to coordinate Low Residual Situations and will help ensure the approach to managing them remains fit-for-purpose and is well understood by industry partners and stakeholders.
Consultation Process
The consultation period is 3 weeks commencing on Wednesday, 20 November 2024. Submissions are due by midday on Wednesday, 11 December 2024. This is followed by a period for cross-submissions. Cross-submissions are due by midday on Wednesday, 18 December.
