Gemini Within Day Auction Issue 

Updated: Monday 05 January 2026 - 11:50am

Background

This morning we experienced an issue affecting within-day entry capacity auctions at the Bacton location, available capacity was displaying as zero. This is prevented bids from being submitted for within-day bids at this location.

Update

A workaround has been successfully carried out to manually publish the correct capacity values, expected capacity is now available. We are investigating the cause and working towards a permanent fix. Further updates will be provided.

Please note Day-ahead auctions were not impacted and are operating as expected.
