Introduction

Last PCR introduced several fundamental changes to the entry regime which included Entry Capacity Substitution

A key intention of the policy measures is to ensure that capacity does not become sterilised, i.e. an obligation at one ASEP where capacity is not required does not prevent use of that capacity elsewhere.

Key Licence deliverables are; Entry Capacity Substitution Methodology Statement Submit to the Authority for approval by 6th January 2009 Amendment of Incremental Entry Capacity Release Methodology

Statement to include substitution. On 1st February National Grid issued consultation document

seeking views on a range of issues.

Capacity Available for Substitution.

• What proportion of baseline capacity should be withheld from QSEC auctions (and substitution) for use in later auctions (the current Licence requirement is 10%)?

Proportion withheld

20% > 10% zero%

In favour 7 1 1

Other comments

Prevents development of liquid secondary capacity market

Capacity Available for Substitution.

• Should allocated capacity or forecast flows be used in defining substitutable capacity?

• Licence defines substitution of “unsold non-incremental obligated entry capacity”.

• Would forecast flows impact TBE data?Definition of

sterilised capacityAbove forecast

flowsAbove allocations

In favour 5 3

Other comments Need to consider projects in developments

Impact of TBE Yes = 4 No = 2

• Alternative suggestion• Use previous year’s peak flow.

Single Quarter Problem.

Where capacity is currently booked at an ASEP for a single quarter in the future should this prevent capacity at that ASEP, to the level booked, being available for substitution in the period prior to that booking?

Users say this should not prevent substitution but a workable solution is not evident at this stage.

In favour Against

Should this prevent substitution? 1 5

Create rules to prevent short-term, distant, bookings? 1 3

Should substitution be time limited? 3 + 1 maybe 1Should a surrender mechanism be created? 4 1

Lower NPV Test.

Should different User Commitment tests be applied for incremental capacity satisfied from substitution and from investment?

Comments Combined Substitution / Investment & Competing Bids is

complex, but should not be an issue with a single test.

In favour Against

Same Test 6 1 (relate to actual costs)

Exchange Rate Cap.

• To avoid excessive capacity degradation should capacity substitutions be prohibited if the exchange rate exceeds a specified value?

• If yes, what should the cap on exchange rates be?

Cap on Exchange Rates

<=1.5:1 2:1 <10:1 10:1 Don’t know No cap

1 1 2 2 1 0

Availability of Capacity for Substitution.

Should National Grid substitute capacity to release incremental capacity ahead of 42 months?

If yes, should any limit be placed on the timing of such release, e.g. 18 months, 30 months?

Should substitution be limited to single donor ASEP or should combinations (substituted at different times) be allowed?

Responses Mainly in favour of early release (from 18 months) provided

capacity has previously been available in AMSEC. Is this feasible? QSEC / AMSEC do not overlap sufficiently.

Impact on incentives to be considered.

Other Issues.

New Entry Points Support for a delaying substitution until a “regular”

QSEC auction. Unlikely to be an issue with April 2009 implementation

date. Assuming UNC mod implemented for April 2009 QSEC.

Alternative Economic Test / User Commitment No support for changing now. Willing to review.

Reserve Price Discounts Conflicting views; 1 totally against discounts, 3 in

favour.

Other Issues.

We would be interested in people’s thoughts as to how the substitution process may impact upon other elements of the entry capacity regime.

6 respondents specifically commented on the need for more time to consider potential consequences

5 refer to a “holistic” approach; consider interactions. 4 respondents identify potential price increases as a

consequence of substitution

1 reference to regulatory Impact Assessment.

Next Steps

Arrange workshops Establish workgroup. Develop policy / processes.

National Grid to draft Entry Capacity Substitution Methodology Statement

Contains process to identify donor ASEPs and quantities. Incremental Entry Capacity Release Methodology Statement

Likely to include most of the business rules to be developed

National Grid consultation to commence Nov 2008 Submit to Authority for approval by 6th January 2009 May need to be earlier to accommodate Impact Assessment
