Exit Update - Annual Application Window - Systems Update - Current Licence Consultation
Transmission Workstream, 6 August

2. Annual Application Window: Update & Next Steps
Reduction window and application window now closed
DCs: 23 increase applications and 12 reduction applications
DNs: 40 increase applications and 11 reduction applications
We will now analyse all of these applications along with initialised levels for purposes of network planning
Allocations will be made in line with the ExCR by 30 September
After DN adjustments to applications accepted beginning September where flex or pressure requests have been rejected
Contact made with some applicants re exceeding MSPOR limit – advise that contact is made with site operator in first instance and customer services for further questions
Ad hoc applications will be accepted from 1 October
We believe that the process went well, but would welcome any feedback.

3. Systems Update
Extensive piece of work to get all exit functionality into Gemini
Likely to be delivered in three phases
Requirement gathering / analysis on phase 1 complete, that stage now started for phase 2
NB Some elements subject to further internal discussion

4. Current Licence Consultation: Licence / UNC definitions
National Grid has become aware of a number of sites that are classified as single Supply Points under the UNC, but have more than one baseline in the Licence
Supply Meter Point = physical location where gas is made available for offtake i.e. the end of the NTS
Supply Point = notional commercial point used for system balancing, deemed gas flow and transitional regime capacity booking
One or more Supply Meter Points can be comprised in a single Supply Point where gas offtaken from the NTS is supplied to premises:
Owned or occupied by one person
In close geographical proximity to each other
Comprised within a common curtilage, and
Which serve each other in some necessary or reasonably useful way

5. Licence Consultation: Issue
In the enduring exit regime capacity is made available at those NTS Exit Points that are listed with a baseline in the licence
Staythorpe, Stallingborough and Didcot all satisfy the single premises requirement but each has two baselines in the licence
This could cause inefficient booking of capacity and unnecessary signalling of incremental where a site has more than point at which it offtakes gas directly from the NTS
If gas can go down either stream then would need to book sufficient at both to avoid exposure to overruns, effectively double counting
If baselines are aggregated, one capacity booking covers both gas streams allowing site flexibility and avoiding exposure to overruns and inefficient investment signals

6. Licence Consultation: Proposals
Therefore propose that, if a site requests it, and Single Premises Requirement is met, then baselines will be aggregated i.e.
Current Name Current Baseline Merged Name Merged Baseline
Didcot A Didcot
Didcot B
Stallingborough Stallingborough (phase 1)
Stallingborough (phase 2)
Staythorpe PH Staythorpe 76.24
Staythopre PH

7. Impacts and Next Steps Responses requested by 13 August 2009
A formal consultation is then expected to be issued mid August, which would allow for any changes to be directed to the licence in September
National Grid will then be able to allocate any applications received in the July Annual Application Window against the merged baselines
The prevailing Maximum Supply Point Offtake Rate or Maximum CSEP Offtake Rate in the relevant NExA(s) will continue to apply
Where users have been initialised at both sites that are being merged, the initialisation numbers will be added together
