Before You Nominate

1. The Customer & NrG Highway

TransCanada assigns an alphabetic code to each customer. Whenever possible, we use the mnemonic assigned by the Alberta System. Example: TransCanada assigns the enterprise mnemonic CGSC to Canadian Gas Shipper Co. This enterprise mnemonic is subsequently used as part of the account name for many of CGSC's accounts.

4. Transportation Services

Tips: Firm Service holders have the ability to nominate to a different delivery point or area not formally contracted for – this is a diversion. Diversions are at the Volume Planners discretion. There is no need to divert to a contracted point.

Tips: Storage Transportation service allows access to storage facilities in conjunction with your firm transportation. When nominating STSO, as a shipper, you are nominating overrun and it has no correlation to gas coming “in” or “out” of storage.

Tips: a master Enhanced Capacity Release contract and a firm service contract or temporary assignment must be in place prior to any Exhibit A’s being accepted. ECR1 and ECR2 must be equal. Diversions are allowed off of the ECR2 leg.

Tips: a master Capacity Release contract and a firm service contract or temporary assignment must be in place prior to any Schedule A’s being accepted. Diversions are not allowed off of a CR.

Tips: is a service designed specifically for the winter period.

Tips: a master STFT contract must be in place prior to any STFT exhibit being accepted. There are no diversion rights to STFT. Any alternate receipt points must be approved and set up on the contract prior to the date the STFT will first flow. Once an STFT bid is approved, it is effective for the time period specifically set out on the exhibit.

Tips: a master Firm Backhaul Transportation contract must be in place prior to any request or Exhibit A being accepted. FBT is for a minimum one month timeframe. There are no diversion rights associated with firm backhaul transportation. Fuel is not required for this service, but there may be a pressure charge.

Tips: Interruptible transportation is a biddable service. The bids are part of the nomination and are in $/GJ displayed to four decimal places (i.e. 0.1234).

For information on this service, its associated tolls and penalties refer to TransCanada’s Transportation Tariff by selecting: http://www.transcanada.com/Mainline/info_postings/tariff/index.htm

Nomination Deadlines

1. Gas Day
TransCanada's gas day begins at 09:00 Central Clock Time (CCT). Each gas day has four nomination cycles:

2. Nomination Cycle
TransCanada follows NAESB (North American Energy Standards Board) nomination cycles and deadlines. The nomination cycle consists of four processes:

For Canadian Mainline Processing Cycles, please select: Canadian Mainline Processing Cycles

Nomination Process

1. Format

2. Identification Section (Fax nominations only)

3. Start Date Time
TransCanada's gas day starts at 09:00 (CCT). Therefore, all nominations for the beginning of the gas day should have a start time of 09:00 CCT. TransCanada also offers two intra-day nomination cycles with start times of 17:00 CCT and 21:00 CCT.

4. End Date Time
Standing nominations are in effect from the start date time until the end of the gas month. Single day nominations are in effect from the start date time until the end of the gas day.
All intra-day nominations expire at the end of a gas day. All nominations expire at the end of the gas month.

Tips: Multi day nominations (i.e. weekend nominations) that expire before the end of the gas month are now supported. Nominations that span across a month end are not supported at this time.

5. Issue Date Time
The issue date time is the time stamp on an electronic nomination or the fax time stamp on a fax nomination. It is used to determine the order in which nominations were received. When two nominations have overlapping effective dates, the nomination with the later issue date time will replace the nomination with the earlier issue date time.

Tips: You should be aware of the potential for confusion when nominations are submitted with overlapping effective dates.
Example:

Nomination 2 will replace Nomination 1 (for the 29th, 30th and 31st gas days) because they overlap and Nomination 2 is the most recent.

6. Locations
For a list of Canadian Mainline Nomination Locations, please select:
Canadian Mainline Nomination Locations

Tips: Some points may only be nominated as receipt points and some points may only be nominated as delivery points.

7. Accounts
For a list of Canadian Mainline Mnemonics, please select: Canadian Mainline Service Classes

8. Services Class
For a list of Canadian Mainline Service Classes, please select: Canadian Mainline Service Classes

Tips: Be sure not to nominate a diversion to a point that is on your contract. Example: If Emerson 2 is listed as a delivery point on your FT contract, a nomination to Emerson 2 with a service class of FT D will fail.

9. Quantities
All nominated quantities are daily quantities in GJ's.

Tips: When submitting intra-day nominations that reduce the nomination in effect, be careful not to nominate a daily quantity that is less than the quantity that has already flowed. This is called Negative Flow. Please see #4 of the confirmation process on page 13.
Example:

Nomination 2 will be rejected because it results in negative flow. Nomination 1 has already flowed for 8 hours so Nomination 2 can not be lower than 34 (100 * 8/24). A nomination can never be reduced to zero in an intra-day cycle.

10. GST Exempt Flag
Transportation to export points is usually considered to be GST exempt, therefore place a "Y" in the GST exempt field. Transportation to domestic points is usually subject to GST, therefore place an "N" in the GST exempt field.

The are two rare exceptions to the above rules.
1. When gas is transported to an export point and is immediately transported to a domestic market, it is not GST Exempt.
2. When gas is transported to a domestic point and is immediately transported to an export market, it is GST Exempt.

11. GST Exemption Declaration
This property is being shipped for export and the freight transportation service to be supplied by the carrier is part of a continuous outbound freight movement in respect of the property.

12. Fuel Ratios
The fuel ratios are listed by receipt location and delivery location pairs. Fuel ratios for delivery pressure compression and STS transportation are listed in separate sections at the end of the fuel ratio list.

Tips: For deliveries to a delivery location that requires Delivery Pressure compression, add the delivery pressure fuel ratio to the applicable transportation fuel ratio.
Example:
For transportation from Empress to Niagara Falls in September 2003:

Transportation fuel ratio for Empress to Niagara Falls is 5.86
Delivery pressure fuel ratio for Niagara Falls is 0.10
Required fuel ratio = 5.86 + 0.10 = 5.96

13. Fuel Calculation
Shippers must nominate sufficient fuel for the nominated transportation.

The following changes for fuel are effective November 1, 2000:

To calculate the required fuel:
1. For each nominated transportation path:
Determine the applicable fuel ratio.
Multiply the transportation quantity by the fuel ratio to calculate the fuel required for that path.
2. Sum the fuel required for all paths to determine the total fuel required.

14. Fuel Nomination
The fuel required is nominated as a delivery from the transportation account to its fuel account. The delivery may be nominated at any location or combination of locations that have sufficient nominated receipts. TransCanada performs it's own calculation of the required fuel and posts it to the MT Fuel accounts. Therefore, any variances between nominated fuel and required fuel are held in this account.

Mainline Capacity Allocation Process

Each day, TransCanada determines if there is sufficient physical capacity to transport the volume of gas nominated by shippers. The volume planners first determine the capacity of the system and the location of the system bottleneck(s). At each nomination window, nominations requested are compared to capacity available. If the capacity available is greater than the nominations requested, the nominations will be approved and receive a status of "Fully Authorized". If the capacity available is less than the nominations requested, restrictions to nominations will be required. Only nominations increasing flow through the bottleneck(s) will face a possible restriction. For those nominations identified as increasing flow through the bottleneck(s), capacity will be allocated based on priority of service. The lowest priority of service will be restricted first and receive a status of "Not Fully Authorized". Restrictions will be done within and then across service categories until the nominations requested match the capacity available.

CA Info Session Final Presentation April 2003

Confirmation Process

1. Account Balancing
After every nomination window has closed and volume planning has allocated the mainline, the Nominations and Allocations department will be working with interconnecting pipelines and customers to balance each point on the system.

Customers, through Customer Operational Reporting, have the ability to monitor their own accounts prior to receiving any calls from the Nominations and Allocations department. By viewing accounts on line, customers will know where their variances are, and can submit adjusting nominations to bring all of their accounts into balance.

2. Options for accounts out of balance
If an account is out of balance, here are some options for you:

If your account is high:

If your account is low:

If accounts are not balanced the Nominations and Allocations department will make every effort to contact customers to establish how and when, during each specific window, we can expect adjusting nominations to be received.

If customers have not responded, and TransCanada is the high number with an interconnecting pipeline, the Nominations and Allocations department will bring all accounts into balance in order to confirm.

Tips: TransCanada makes every effort to process but not authorize all weekend nominations on Friday. This allows customers to view their weekend business on Customer Operational Reporting in advance.

Prior to any month end, TransCanada makes every effort to process but not authorize all “first of the month” nominations so that customers can monitor their own accounts on Customer Operational Reporting leading up to the start of the month.

3. “Lesser Of” Rule

TransCanada works closely with interconnecting pipelines and customers to balance each receipt and delivery point on the system for every nomination cycle. Where there is communication between TransCanada and the interconnected operator and agreement is not reached by the deadline regarding the confirmation quantity, the lesser of the 2 confirmation quantities becomes the confirmed (scheduled) quantity. In the event there is no communication between TransCanada and the interconnected operator, the lesser of the requested confirmation quantities or the previously scheduled quantity becomes the confirmed (scheduled) quantity.

4. Negative Flow
In processing nomination changes for intra-day windows, a decrease at a receipt or delivery point on any nomination can not go below that portion of the day that has already flowed for any Class of Service.
For example: If at 0900 you were transporting 100 GJ’s from Empress to Niagara Falls, at 1700 you could not reduce that nomination below 34 GJ’s.
