[edit] Changing Point Capacity

Select Customer Activities -> Physical -> Location. You will be directed to the Location screen.

Retrieve the point for which you wish to specify the capacity. Press at the top of the Location History matrix. Enter appropriate date ranges and point capacities. Press at the top of the screen to save your changes.

NOTE: For Storage (INV), injections are backhaul capacity and withdrawals are forward haul capacity

[edit] Changing Internal Constraint Capacity

[edit] Step 1: Finding the Constraint Point

Select Customer Activities -> Flowing Gas -> Graphical Pipe. You will be directed to the Graphical Pipe.

Finding the Constraint Point

Check the Capacity Constraint checkbox. Select the Get Feature Info tool (yellow qustion mark). Click on the desired internal constraint. Note the Point Code displayed.

[edit] Step 2: Finding the Constraint Segment

Select Customer Activities -> Physical -> Location. You will be directed to the Location screen.

Image:Cap phloc.jpg Finding the Constraint Segment

Retrieve the point of the constraint using the Point Code gathered from the Graphical Pipe screen. Note the segment to which the point belongs (Pipeline Segment field).

[edit] Step 3: Changing the Segment Capacity

Select Customer Activities -> Physical -> Section. You will be directed to the Section screen.

Retrieve the segment of the constraint Select the Capacity tab. Click at the top of the matrix. Fill in the required field to enforce the internal constraint. Click at the top of the screen to save your changes.

[edit] Unsubscribed Firm Capacity Screen/Report

Select Customer Activities -> Physical -> Unsubscribed Firm Capacity. You will be directed to the Unsubscribed Firm Capacity screen.

Click at the top of the screen. Select the receipt point. Select the delivery point. Enter Capacity. Enter Begin and End Dates. Click at the top of the screen to save changes.

[edit] Physical Capacity Allocation Special Considerations

[edit] Boswell's Tavern

Select Customer Activities -> Contracts -> Contract. You will be directed to the Contract screen.
To artificially inflate the MDCQ (for Capacity Allocation) for nominations coming from any point and going through a particular point, complete the following steps:

• Retrieve the contract you wish to modify.
• Select the Rights >> Input tab.
• Click at the top of the Capacity Allocation matrix. Fill out the fields in the following manner:
  • FromPoint Low - Leave blank.
  • ThroughPoint Low - Enter 833097
  • Vol - Enter a keyword or a number (for example, Nomination).
  • VolMultiplier - Enter Gas Price Index or a number (for example, TranscoFuel).
  • Limit - Enter a keyword or a number (for example, MDCQ).
  • AdjustParam - Enter MDCQ.

NOTE: If the MDCQ were 10,000 on this contract, and the TranscoFuel rate were specified at 0.02, the MDCQ would be inflated to NomiationQty x 0.02 up to a limit of (10,000 x 0.02 = 200).

[edit] Storage West and Storage East

Select Customer Activities -> Contracts -> Contract. You will be directed to the Contract screen.
To exclude a volume from being constrained at a segment, complete the following steps:

• Retrieve the contract you wish to modify.
• Select the Rights >> Input tab.
• Click at the top of the Capacity Allocation matrix. Fill out the fields in the following manner:
  • FromPoint Low - Enter STOR.
  • ThroughPoint Low - Enter CERELANH (the Lanham internal constraint segment).
  • Vol - Enter 4000.
  • VolMultiplier - Enter 1.0.
  • Limit - Enter 4000.
  • AdjustParam - Enter NomExclude.
  • ContractRel - Enter EStorage (Used only for Lanham Bypass on linked contracts – see further info below. Otherwise, leave blank).

NOTE: In this example, a contract with nominations from 'STOR' to some delivery point that pass through the Lanham constraint segment would be allowed 4000 to pass through Lanham without being subject to the Lanham constraint. Remaining volume above the 4000 would then be subject to the Lanham constraint.

In order for a transport contract to use the Lanham bypass, the storage contract which it is pulling from must be identified with an Estorage relationship in the Related Contracts tab of the transport contract. Without an Estorage relationship, the Lanham bypass will be ineffective.

• Select Customer Activities -> Contracts -> Contract. You will be directed to the Contract screen.
• Select the General >> Related Contract tab.
• Click at the top of the Forward Relationship matrix.
• Enter the storage contract number, Relationship Type (Estorage) and Effective Begin and End Dates.
• Enter the Related Transport and Related Point code (optional).
• Click at the top of the screen to save your changes.

NOTE: In order for an SST to nominate to an FSS in the ID3 cycle, it must have an Estorage relationship established on the Related Contract tab of the SST contract. Furthermore, the ability to place such a nomination can be further constrained by the Primary Requirement parameter on the Nominations Right, which specifies if the receipt and/or delivery points must be primary.
