Dear Market Participants,
SEMO have identified two manifest errors in the calculation of the Imbalance Settlement Price.
A Wind Dispatch Instruction data error has resulted in incorrect Dispatch Instructions being applied to the Imbalance Price calculation, for a number of wind units. This issue impacted from 03:45, on the 16th October 2019 to 10:00 on the 17th of October 2019.
An issue occurred on a specific unit resulting in the inconsistent calculation of QAO/QAB during Min on time of that unit (KIR: 6104). This occurred between the hours of 07:00am to 09:00am on the 17th of October.
SEMO are currently investigating the underlying cause of these issues.
Kind regards,
SEMO Trading Operations
