Market insights
2024 reached its low point a month ahead of average (usually around mid September). 2021 and 2022 were considered dry years.
A shortage of gas combined with low rain and inflows into our hydro lakes has created a severe fuel shortage which is driving up wholesale electricity prices.
We've published a new report that shows scheduled generation outages by generation type, participant and island.
This report has been produced to better enable the monitoring of scheduled outages through winter 2023 and beyond. In our 9 March 2023 decision paper on 'Driving efficient solutions to promote consumer interests through Winter 2023', we noted that there was a significant level of non-thermal generation on outage during periods the system operator indicated were potential tight supply periods.
The data used in today's report is obtained from the Planned Outage Coordination Protocol (POCP) database. It's an application maintained by the system operator that allows asset owners to provide information on planned outages.
