Operational Costs Levy

This dataset includes the actual, forecast, and excess CfD Operational Costs and demand volumes for the current and historic operational periods.

An electricity supplier must make a payment (“an operational cost payment”) to the CfD counterparty for each day that supplier makes an electricity supply during an operational cost period. The amount of an operational cost payment to be paid by a supplier for a day is equal to the amount of electricity supplied by that supplier on that day multiplied by the operational levy rate.

Any amounts received by the CfD counterparty greater than the costs it incurred in respect of the relevant period must be paid back to electricity suppliers.

This dataset is updated following the end of each financial year.
