In this study we have explored how a simple interim measure in the treatment of Ireland’s battery storage fleet can unlock savings for end consumers during the coming winter, helping to alleviate the cost burden imposed by extreme commodity prices.
Key findings – what have we learned?
-
A total of 471 and 200 MW of battery storage capacity is currently installed in Ireland and Northern Ireland respectively – with storage volumes totalling 334 and 125 MWh.
-
However, current TSO policy concerning battery storage is to re-dispatch these assets down to zero, to hold them back to provide reserve services, or for TSO-controlled dispatch during amber alert periods.
-
This approach limits the effectiveness of battery storage assets to alleviate the cost burden imposed on end consumers this winter, in which extreme commodity prices are expected to drive end consumer bills to record levels.
-
An interim measure that would unlock the full potential of battery assets to reduce end consumer costs this winter would be to offer them deemed-firm dispatch status:
-
Under this policy intervention, the participation of batteries in the day-ahead market would act to reduce the overall cost of meeting demand levels in the day-ahead schedule. Our analysis suggest that this could equate to a saving of around €34m and €11m in Ireland and Northern Ireland respectively this winter.
-
The saving exceeds any net increase in imperfections costs from the battery imbalance – with total net savings of up to €26m and €9m in Ireland and Northern Ireland respectively this winter.
