New EMI report: scheduled generation outages
We've published a new report on EMI 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.
Security of supply while two thermal generators are on outage
The ability of electricity supply to meet demand over time is referred to as 'security of supply'. It's about the availability of enough generation capacity ea…
