Dear participants,

SEMO carried out the material assessment for the below issue and came to conclusion there will be no additional settlement of M+4 MO charges for February 2021 carried out due to a low materiality.

The next scheduled resettlement run (M+13) will include the correct VAT rate of 23 % for any changes caused by new metering submissions received for this run.

If you have any further questions please submit your query to info@sem-o.com. 

Apologies for any inconvenience caused.

Kind regards, 

SEMO Settlement
