Regulation 21 Periodic levelisation paymentsI1I2

The Authority must determine and publish the periodic levelisation periods which are to apply in F1... respect of each OLR year.

The determination under paragraph (1) must be made—

Each periodic levelisation period must be a period of 3 months or less which falls within the OLR year to which a determination under paragraph (1) relates.

The Authority may vary the periodic levelisation periods which are to apply in an OLR year and must publish notice of any such variation at least one month before the variation takes effect.

Subject to regulation 18(5), the Authority must calculate the periodic levelisation payment which each licensed supplier is required to make or is entitled to receive for each periodic levelisation period.

A calculation under paragraph (5) must be based on the Authority’s estimate of the difference between the licensed supplier’s OLR contribution^f1 and its market share OLR contribution^f2 for the OLR year in which the periodic levelisation period falls.

If the OLR contribution of a licensed supplier for the OLR year is estimated to be greater than the licensed supplier’s market share OLR contribution, the licensed supplier is entitled to receive a periodic levelisation payment from the Authority equal to the difference between those amounts.

If the OLR contribution of a licensed supplier for the OLR year is estimated to be less than the licensed supplier’s market share OLR contribution, the licensed supplier must make F2a periodic levelisation payment to the Authority equal to the difference between those amounts.
