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.
We've released a new report that shows the trend in real-time dispatch prices for energy.
With the implementation of real-time pricing on 1 November 2022, interim and final prices are now calculated as a time-weighted average of the real-time dispatch prices at the end of the trading period. Previously, interim prices were published the following day with final prices being declared the next day.
Sometimes when a trading period starts, the first dispatch price for that period has not yet been calculated so the price for the most recent PRSS SPD case price is used.
This new report allows you to select a day and one or more points of connection to view the trend in real-time prices as well as the cases and weightings used to calculate interim and final prices. There is also a version of this report for reserve prices.
