CHAPTER IV U.K. RECONCILIATION OF REVENUE

Article 18 U.K. Under- and over-recovery

1. The under- or over-recovery of the transmission services revenue shall be equal to:

• R_A – R

Where:

• R_A is the actually obtained revenue related to the provision of transmission services;

• R is the transmission services revenue.

The values of R_A and R shall be attributed to the same tariff period and, where an effective inter-transmission system operator compensation mechanism referred to in Article 10(3) is established, shall take such mechanism into account.

2. Where the difference calculated in accordance with paragraph 1 is positive, it shall indicate an over-recovery of the transmission services revenue. Where such difference is negative, it shall indicate an under-recovery of the transmission services revenue.
