Mod Proposal A086 –Incentives for intra-day Balancing

SLIDE 12

Outline of proposed GNI Modification A086

  • Modification Raised by GNI to address concerns that the aggregate system imbalance intra-day is creating
  • perational difficulties.
  • At times, there are large deviations between the prevailing exit nominations on the system and the prevailing

entry nominations. GNI wish to introduce an incentive to encourage more alignment of entry and exit

  • PROPOSAL: At check points during the gas day (11:00, 17:00, 23:00) a shippers portfolio Nomination Imbalance

position will be recorded.

  • A tolerance will be applied at each point
  • Worked Example:

A shipper has 24 units of Aggregate Exit Nomination at 11:00. ‒ Deemed flow at Exit = (24 units * 6hrs/24hrs) = 6 units ‒ Total Entry Nomination = 4 units ‒ Apply a [10%] tolerance: Adjusted Nomination Imbalance Position

  • Nomination Imbalance Position = (6 * 90 %) – 4 = 1.4 units

‒ The Adjusted Nomination Imbalance Position at the 3 time checks will be added ‒ The total for the day will be multiplied by [SAP] * [x%] ‒ The amounts for each day in a month will be invoiced at month end.

Impact if Code Mod was applied in November 2017 –December 2018

  • There was a marked improvement in Shipper Nominations following discussions of the proposed modification at

recent code mod forums

  • However, during Mid February to June late day nominations (attributable to 3 Shippers) has resulted in almost

hourly batches late in the gas day, causing operational difficulties once again for both GNI and National Grid

  • Since July 2018 there has been continued improvement in intraday behaviour

Code Modification Proposal A097

  • AMENDMENT OF FINAL EXIT ALLOCATION DATE
  • MODIFICATION PROPOSER : GAS NETWORKS IRELAND
  • PURPOSE : TO AMEND THE FINAL ALLOCATION DATE IN RESPECT OF LDM OFFTAKE(S), DM

OFFTAKES, NDM SUPPLY POINT(S) AND SUB-SEA OFFTAKES FROM D+5 TO M+5 (i.e. 5 CALENDAR DAYS AFTER MONTH END)

slide-20
SLIDE 20

Code Modification Proposal A097

  • Present Position
  • Sect.2.9.2 of Part D of Code provides that “ The Transporter shall make available to

Shippers the Final Allocation in respect of a Shipper’s LDM Offtake(s), DM Offtake(s), NDM Supply Point(s), and/or the Sub-Sea Offtake by 16:00 hours on D+5”

  • Meter cleansing takes place at the start of a calendar month for a preceding month which is

after D+5

  • Transporter cannot correct billing issues uncovered after D+5 other than as a cumulative

month end adjustment which is not date specific and hinders Shippers in detailing their customer invoices

20 |

slide-21
SLIDE 21

Code Modification Proposal A097

  • Effect of Proposal Implementation
  • GNI will be able correct metering issues as they arise, adjust the metered quantity for the

day, reallocate and issue more accurate monthly allocation statements/invoices to Shippers

  • Shippers will be able to issue accurate statement/invoices to customers and will not have to
  • btain subsequent account adjustments.

Code Modification Proposal A097

  • Three Industry queries received and two have been responded to by GNI.
  • Third query will by discussed by GNI with Industry querist before end January
  • Note of queries and responses will be furnished by GNI to CRU before next CMF Meeting

AOB Item No.4 - Gas Quality – Wobbe Index Increase

  • GNI previously provided an update on Gas Quality to

the CMF on the 27th Nov 2017

  • Focus then was on IGEM continuing it’s review of

GS(M)R and combustion parameters, in particular increasing the Wobbe Index (WI) upper limit from 51.41 MJ/m³ to 53.25 MJ/m³

  • Principle drivers in increasing the WI allows a wider

range of gas supplies to enter the network

  • Currently, IGEM review is still in progress
  • GNI has carried out an impact assessment of potential

changes in the UK natural gas interchangeability requirements on the Republic of Ireland

35

SLIDE 36

Impact assessment conclusions / recommendations

Conclusions

  • In principle, the ROI gas industry is relatively modern, and the domestic appliance population is estimated to be

newer and more tolerant of a wider Wobbe range

  • Further information on domestic, commercial and industrial appliances would benefit a more thorough

assessment of impacts on gas consumers Recommendations

  • It is likely that the studies currently being carried out for the IGEM GQWG, in conjunction with ROI appliance

population data, ought to allow an assessment to be made for the ROI This topic should be an Industry concern (shippers) and not merely one for the transporter

  • Information on commercial and industrial appliances in use in ROI is not available and further assessment of

these sectors is recommended

  • Similar customer surveys completed in UK should be completed in ROI
