Enhancement to Flow Day Diversions related totheEPNG Rate Case in Docket No. RP10-1398-000
- Shipperswill be able to submit nominations to request to flow day divert (FDD)scheduled quantities to any delivery point on the EPNG system whether the delivery point is in a zonethat is upstream or downstream of the original delivery point.
- Flow Day Diversions to delivery points on the Mojave Pipeline system using your EPNG transportation agreement are not supported because of the complexity of this process. If you have any issues with nominating to Mojave delivery points through your EPNG capacity using the regular nomination process, let your Nominations & Scheduling representative know so they can work with you.
- There will be three new features to assist shippers in entering FDD transactions:
1)There is a new drop down menu in the “Up Pkg” field within the Nominations Screen :
The dropdown will have three fields:
a)The available Up Pkg(s)
b)The Additional FL&U (AFL&U) that will be used with that Up Pkg
c)Quantity available to divert using that Up Pkg.
2)Quantity Available to Divert (“QAD”) Detail Button and Screen:
In the Totals tab, a new button has been added under the FDD section.
When pressed the QAD Detail screen appears:
This screen shows:
a)The original delivery location
b)The new delivery location used for the FDD transaction
c)The Quantity Available to Divert
d)The original FL&U
e)The FDD quantity
f)The new FL&U
g)The calculated AFL&U.
3)FDD AFL&U Calculation Report:
This report shows the transactions available to divert and if any FDD transactions exist, which of these available transactions were used as the source for that diversion. It also shows the receipt and delivery combinations used to calculate the FDD and original FL&U. Note: One FDD transaction could source from multiple original nominations.
Example 1:
Shipper originally transports gas from the Bondad Pool to IMSQUITE which is charged Mainline FL&U:
The shipper wants to divert a portion of their scheduled quantities to DSCALEHR (which is downstream of IMSQUITE):
In this example, the shipperwas already assessed Mainline Fuel when they transported gas to the original delivery point (IMSQUITE). The Flow Day Diversion transaction going to DSCALEHR will not be charged any additional fuel as such fuel charge is less than or equal to Mainline Fuel.
The “Up Pkg” dropdown, report and QAD Detail all show zero AFL&U:
Example 2:
Shipper originally transports gas from the Keystone Pool to IKEYSTOR which is assessedproduction area, Permian Basin, fuel plus L&U:
The shipper wants to divert a portion of their scheduled quantities to DSCALEHR (which is downstream of IKEYSTOR):
In this example, the shipper was already assessed Production Area fuel and L&U when they transported gas to the original delivery point (IKEYSTOR). The Flow Day Diversion transaction going to DSCALEHR will be charged AFL&U because it will be transported out of the basin to a mainline delivery point.
The “Up Pkg” dropdown, report and QAD Detail show this AFL&U:
Example 3:
If the shipper has multiple transactions to the original delivery point with multiple FL&U rates, then it is possible to have multiple AFL&U rates associated with a specific diversion.
- Shipper originally transports from:
a)Anadarko Pool to IBIGBLUE
b)Keystone Pool to IBIGBLUE
c)Bondad Pool to IBIGBLUE
The shipper wants to divert a portion of their scheduled quantities to IKEYSTOR:
The “Up Pkg” dropdownand QAD Detail Screen now show 2 possibilities for the Up Pkg, based on the different original FL&U rates.
It is important to note that the original source nominations that will be used first are those that provide the best AFL&U with the lowest original FL&U.
If all original FL&Us are equal:
- The best ranked original source nomination will be used.
- If all ranks are the same, the nomination with the highest quantity will be used.
- If all quantities are the same, then the first entered nomination will be used.
Another note is that one FDD can be sourcedthroughmultiple original nominations.
In this screenshot, the FDD uses 2 original nominations at the 0% AFL&U rate. This has been filtered to show only the FDD “Up Pkg”:
After the transaction has been submitted, the shipper can no longer select a different “Up pkg” without entering a new transaction. Because of this, the QAD Detail no longer shows any rows for a different“Up Pkg”than the selected one:
The report is available after the timely cycle has been scheduledto show the nominations that can be diverted; the FDD only appears on the report after that FDD has been submitted even if it is not yet scheduled:
The report will change dynamically, depending on any changes to the set of FDDs and/or source nominations.The report will become final once the gas day has been completed and no more nomination changes can occur:
