SNG’s facilities performed well during the extended cold
Compressor stations staffed 24x7 as needed
Horsepower reliability
Selma back in service a month early
Limited windows for system recovery
Storage assets were heavily utilized
Freeze offs and supply shorts created system challenges
12 days of OFO system mean ranged from 24 to 41
Sustained cold not just during peak morning/evenling loads
Type days. Avoided a Type 3, needed supply on the system after no time to rebuild linepack

7. Where does January 2018 rank?
SNG Deliveries Only
New peak day record- January 18, 2018
Highest month on record
Third highest LDC month on record
SNG/EEC Deliveries:
Highest Power demand day for any winter month on record

8. Weather and Throughput

9. Winter Heating Degree Days (HDDs*) 2013-2018
In 2014, coldest month was January, but in 2015 February was the coldest month
January 23% above 30 year average – 2016/2017 anomoly as we did not see the cold last January
*HDD = 65 Degrees Minus System Mean Temperature

* 12 Month average ending June

14. January CSS/ISS Storage Withdrawal vs. HDD
Storage assets were heavily used by customers no restrictions were necessary due to adequate inventory levels.

15. Customer CSS Inventory

16. OFO’s Issued to protect you.
Hourly takes, putting in an intraday nomination for gas that was already taken at the start of the gas day
Conscious of what happens when you take gas that is not scheduled
The Type 3 doesn’t protect against supply not showing up. Reason we needed the type 6.

17. OFO’s Used to protect system integrity and primary firm
Type 3 OFOs were in place 35 days Nov-Feb
18 days in January
12 consecutive days with system means below 41
Of those, 6 in a row were below 30 degrees
Limited windows for system recovery
Type 6 OFOs were implemented when necessary to protect under deliveries to the system
12 days of OFO system mean ranged from 24 to 41
Sustained cold not just during peak morning/evenling loads
Type days. Avoided a Type 3, needed supply on the system after no time to rebuild linepack
Weather Forecast – system means in the 40’s and 80’s are where demand starts to approach capacity
Day of week – weekday demand exceeds weekend/holiday demand
Expected duration of heavy demand
Recent history
Nominated deliveries
Actual takes from the system higher than entitlements

18. System Demand/Mean Temps/OFOs January 2018

27. Transportation/Storage Services Cross-Training Initiative
In October 2017, SNG Scheduling reorganized its scheduling team
Katie Cornutt – Manager, Daily Scheduling Reps for SNG
Cathy Soape – Manager, Evening & Weekend Scheduling Reps for SNG & TGP
In Winter 2017, TSS began an effort to cross-train the Scheduling Managers and the SNG/TGP WEAR team
Management On – Call Rotation effective April 2, 2018
Katie Cornutt, Cathy Soape, & Debbie Vasquez (TGP DSR Manager) now share coverage responsibility on a weekly rotation.
The WEAR Team was cross-trained to handle TGP & SNG (“Eastern Region”) on a rotational basis

33. Historically Constrained Areas
Many constraints have been consistent with years past
North Louisiana - Onward (Segment 30)
Southeast Supply Header (SESH)
# ETC Tiger/SNG SESH
# EGT/SNG SESH
FGT-Suwannee (pin #600258)
Ellerslie Compressor Station (Segment 490)
New constraints in Winter 2017/2018
Selma (Segment 460)
Rankin (Segment 400)
Duncanville Lateral (Segment 90)
Always tight through 400 due to it being in the path for storage – additionally the north system supply that increased this winter and made its way south.

34. Restrictions & OFO Overview Scheduling Perspective
Factors considered in scheduling
Contracted No Notice – doesn’t have to be nominated and forecasted usage needs to be reserved
Receipts downstream of constraint increase SNG’s ability to deliver
Actual takes from the system vs entitlements
Expected duration of heavy demand
As soon as a new restriction and/or priority level is identified an updated pipeline conditions report is posted.
Notes: OFOs are used to protect primary firm services

35. Pipeline Conditions Notice
We do include OFO’s in effect. Would it help to include warnings also? Or would that cause confusion?

36. Pipeline Conditions Posting
Do you like this notice and the frequency?
Timely each day and IF there are changes
Would including OFO Warnings on this notice be helpful or cause confusion?
Would any other additional information be helpful on this notice?

37. DART Prioritization List Update Scheduling Items

38. Recently Completed Add Totals to Cut Notices
Up/Dn Arrows cause Rec Qty (Gross), Del Qty (Net), Up Rank/Del Rank, Dn Rank/Rec Rank, Rec Loc Prop/Up ID Prop, and the Del Loc Prop/Dn ID Prop to increment/decrement.
New Report- All Activity for GID
New Report format
Buy/Sell Activity by Location
Keeps summary view
Suppress Zeros on Reports
Exclude 0’s from reports when nominated volume= 0.
Shipper summary
Shipper detail
Operator summary
Operator detail

39. In Progress: Confirmation Changes
SNG will be introducing a Sub-Cycle indicator starting May 1st, which will allow Operators to control the volume they would like to confirm and roll from cycle to cycle.
Operators can confirm their volume at Timely Cycle and set the sub-cycle indicator to “yes.”
The Pipeline will not confirm over that specified volume for the gas day.

40. In Progress: Confirmation Changes
New Feature we have added is our Sub-cycle indicator. This will allow the confirming party to hold a specified volume for that day.
Double Click

41. In Progress: Confirmation Changes
There are two levels to confirm at: Location and Transaction.
Each day is treated as a new day. Whatever is confirmed for Timely Cycle is what will roll for that day.
*Note- Volumes will not roll across multiple days.

42. In Progress: Copy Batch Enhancement
To copy a previously submitted batch:
Batch MUST be in submitted status
Right click and select “copy”

43. In Progress: Copy Batch Enhancement
On add screen enter the new date range, cycle, etc.

44. In Progress: Copy Batch Enhancement
The meters and volumes will copy into the new batch
If contracts in the copied batch are no longer valid you will get an error and will need to nom with a valid contract

45. In Progress: Zero Fill Line Items
If you enter a Timely transaction that does not go through the end of the month, Dart will build the transaction with a zero for the remainder of the month.
This is to save you from having to re-enter that transaction if you decide to use it again before the end of the month.
Is this feature utilized or could it be removed without causing problems for users?
We think it could enhance performance

46. Open Scheduling & Reporting Items
WNVL003_RS Scheduled Qty Shipper Summary Report Subscription

47. Newly Requested Scheduling & Reporting Items
It would be useful to find a way to edit Path Rank directly from the Capacity End Point screen.  Ideally a shipper could see results on the Capacity End Point screen, then change the path ranks for the next cycle, and re-submit without having to open the Contract Path Ranking screen, find the path and submit from there.
Creating a column on the MDQ Utilization screen that captures just the total nomination on FT, FTNN, MFTE, etc. as it was previous Dec 1, 2017
Is it possible to change the sort order in the Report Subscription adhoc windows? For example, in the WIVL9000, could we sort in alpha order instead of GID numeric order?
It might be useful to break the Petal Storage Interconnect into separate receipt and delivery points.  For example, when we nominate both a Petal withdrawal and a Petal injection, any constraints on the downstream end of the withdrawal will flow back to the supplier on the upstream end of the injection if rankings are not correct.

57. Next Steps Prioritized List Returned by May 25, 2018
Next Customer Working Group WebEx Meeting
August 16th at 1:30 PM CST
Now that we have presented some of the newly requested items as well as gone over remaining items, we will compile the list and it out to be prioritized and returned SNG by May 25th.
Currently we have our next CWG WebEx scheduled for August 16th which follows our Quarterly method of hosting WebEx’s
Do you all feel that Quarterly meetings works for you and your business? Or is this too frequent? Or would it be better to meet 2 times a year instead?
We want the WebEx calls to be an efficient use of your time.
It does not have to be DART related, does anyone have any final questions or comments?
Thank you to everyone for being in attendance today and for calling in to participate in our CWG.
