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 17^th 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
