Existing licence obligations under SSC A4, A5 and D11

Under SSCA4 of the GT licence which governs charging, DNs have the following reasonable endeavours obligations to:

• only update distribution charges once a year on 1 October, or at any other time as directed by the Authority*; and

• provide the Authority with indicative charges 150 days prior to updating the level of distribution charges.

Note: * obligation also contained in SSC A5 and SSC D11

Ofgem review of existing licence obligations

Ofgem is reviewing both obligations against a background of significant variability in the level of gas distribution charges since the introduction of individual Distribution Network (DN) charging regimes.

We consider that amending these licence obligations in conjunction with other measures being considered should have the effect of significantly reducing this variability.

Other measures are:• Gas Distribution Price Control proposal to remove the volume related

revenue driver, and• UNC Mod 160 to provide shippers with better information on PC revenue

Reasons for the review

Ofgem has identified the following concerns with each obligation:

1. Only update distribution charges once a year on 1 October

• produces a mis-match between the charging and price control formula years, which has been a significant contributing factor to the variability in the level of charges because:

adjusting the level of charges on 1 October mid way through a formula year requires that the magnitude of any change aimed at meeting a target allowed revenue over the full year must be greater than if the adjustment had been made at the beginning of the period; and

variability tends to be reinforced over time as a large increase in one period leads to the need for a large decrease in the next and so on.

Reasons for the review cont.

2. Provision of indicative charges 150 days prior to updating the level of distribution charges.

• While indicative charges in general tend to signal the direction of movement in definitive charges, they are less useful in signalling the magnitude of change.

• Variance due to the requirement for a 150 day notification period meaning indicative charges when compared to definitive charges:

are based on three months fewer throughput data (with data for the important shoulder months of April & October excluded)

do not reflect the effect of the final REPEX incentive adjustment to allowed revenue which is in mid July.

Proposals for licence modification

1. Allow DNs to update distribution charges twice a year on 1 April and 1 October

• Retaining October date would allow DNs to consider the effect of variations in throughput on allowed and collected revenues during the first half of the formula year, and

• Adding the April date would give flexibility associated with aligning the charging and formula years.

Better facilitate DNs in discharging their licence obligations with respect to setting charges such that they do not over or under recover against allowed revenue. In turn will minimise variability in level of charges.

2. Reduce the indicative notice period from five to three months

• Would make indicative charges a better reflection of the subsequent definitive charges.

Ofgem consultation letter proposing the modification published 20 July 2007

Timetable

• End August 2007: deadline for responses to Ofgem consultation letter

• September 2007: pending response to consultation letter publish statutory notice proposing to modify SSCs A4, A5 and D11

• October 2007: pending representations received to statutory notice modify SSCs A4, A5 and D11
