ATC Posting for Monthly Service Commencing October - RESOLUTION

Posted on August 18 , 1:42 p.m.

In the bulletin posted 6 August 2004 @ 11:20, BCTC stated that customers who submitted transmission requests for one month duration, for the month of October, either with Stop Times of 23:00:00 (pursuant to the ATC posting) or 00:00:00 (pursuant to BCTC requirements), had their requests deemed INVALID or REFUSED, respectively. Upon further investigation, we have concluded that the latter statement is incorrect. In fact, our scheduling system CONFIRMED a transmission request, for service in the month of October, that was submitted with a Start and Stop Time of 00:00:00.

In that same bulletin, BCTC stated that it would endeavour to ANNUL the CONFIRMED transmission reservations, manually process all transmission requests received for Monthly Firm and Non-Firm transmission service based on the OASIS time stamp, and post the manual audit trail for transparency purposes. Since then, we ANNULLED the CONFIRMED transmission reservations and manually processed transmission requests based on the OASIS time stamp wherein Right of First Refusal was offered to appropriate requests during the displacement process for the BC paths including wheelthroughs.

During the manual processing, we worked with the successful parties of this competition (to date) to submit "replacement" transmission reservations (#1334312 and #1334305) on OASIS thereby eliminating further manual displacement processing of subsequent Firm and Non-Firm Monthly transmission requests while during the Conditional Until time.(Refer to Section 4.3, Scheduling Timelines, for details.) Therefore, further potential displacements will resume on OASIS for transparency purposes.

For ease of viewing, we are providing a document entitled Explanation of Processing, October 2004 Monthly Posting Anomaly. In addition, we are providing details that illustrate the automated processing and subsequent manual processing in two documents entitled EAL to BC Processing and BC to EAL Processing. We thank you for your patience and cooperation regarding this matter.

BC Import Capability Study

ATC Posting for Monthly Service Commencing October

Posted on August 6 , 11:20 a.m.

At 00:00:00 (midnight) on 2 August, BCTC's posted capacity on OASIS for Monthly Firm and Non-Firm transmission service for October 2004 forward became available for purchase. Typically, capacity is posted with a Start Time of 00:00:00 and a Stop Time of 00:00:00. However, capacity posted for the month of October had Start and Stop Times of 00:00:00 and 23:00:00, respectively. This posting anomaly was caused by a system error as a result of Daylight Savings Time (time zone falls back one hour) occurring on the last day of October. Therefore, customers who submitted transmission requests for one month duration, for the month of October, either with Stop Times 23:00:00 (pursuant to the ATC posting) or 00:00:00 (pursuant to BCTC requirements), had their requests deemed INVALID or REFUSED, respectively. Those customers who submitted transmission requests for duration longer than one month circumvented this system anomaly and their requests were CONFIRMED despite queue priority. As a result of the system error, over the next week BCTC will endeavour to ANNUL the CONFIRMED transmission reservations and manually process all transmission requests received for Monthly Firm and Non-Firm transmission service based on the OASIS time stamp. Once complete, BCTC will issue another bulletin attaching the manual audit trail for transparency purposes. Thank you for your patience and cooperation.

BC-Alberta Intertie Firm TTC Confirmation

Posted on July 30 , 10:14 a.m.

Further to the bulletins posted on June 28, 2004 @ 16:06, TTC on the BC-Alberta Intertie, and July 26, 2004 @ 14:42, Update on BC-Alberta Intertie Firm TTC, BCTC will follow up with the AESO to improve co-ordination of TTC. In the meantime, BCTC confirms that the Firm TTC limit on the AB > BC path will remain at 300 MW as described in the aforementioned bulletins and in BCTC’s Business Practices.

Please contact Mark Prosperi-Porta at (604) 699-7385 for more information or if you have any questions/comments.

Changing S.Slocan POR/POD to KI POR/POD

Posted on July 26 , 2:48 p.m.

The POR/POD interface between BCHA and other parties’ systems has changed. As a result, Market Operations is changing the S.Slocan POR/POD name to KI(Kootenay Interconnection) effective 28 July. An OASIS outage on 28 July from 13:00 to 13:10 will be required to facilitate this change (refer to OASIS Outage Back-up Procedures. Once KI is downloaded by eTag vendor, it will show up as an option for eTags; however, eTags will be denied if the POR/POD does not match the OASIS request. Therefore, before the OASIS outage customers must use S.Slocan POR/POD on OASIS and eTags. After the outage, customers will only have the option of using KI on OASIS. The eTag system will show both S.Slocan and KI, but customers must use the new KI POR/POD. The S.Slocan POR/POD will be deactivated within 48 hours.

For clarity, the modified steps include:

Step	Result
1. Add KI POR/POD in the TSIN Registry.	- S.Slocan available on OASIS and eTag – Customers use this POR/POD.
2. TSIN Registry updated and NERC e-mail released (Within 24 – 48 hours from Step 1).	- S.Slocan available on OASIS and eTag – Customers must still use this POR/POD.
3. Etag vendor completes download of new NERC registry (up to 24 hours from Step 2).	- KI POR/POD available on eTag system at 00:00:00 of the day after download from NERC Registry. - S.Slocan available on OASIS and eTag – Customers must use this POR/POD.
4. OASIS Outage for approximately 10 minutes to change the POR/POD name from S.Slocan to KI.	- Outage called by BCTC after Step 3. - Before the outage, Customers use S.Slocan POR/POD. - After the outage is over, Customers must use the KI POR/POD on OASIS and eTag. S.Slocan is still available for eTags, but will be denied if used. S.Slocan POR/POD will no longer be available on OASIS.
5. De-activate S.Slocan from eTag after Step 4. Deactivated on OATI within 24 – 48 hours after Step 4.	- Customers must use the KI POR/POD from then on.

Thank you for your patience and cooperation.

Update on BC-Alberta Intertie Firm TTC

Posted on July 26 , 2:42 p.m.

Further to BCTC’s bulletin posted on June 28, 2004 @ 16:06 - TTC on the BC-Alberta Intertie, BCTC provides the following graphical summary histogram of number of hours during January 1999 – May 2004 where BC>AB TTC (final posted TTC) was below the values on the X-axis. For example, BC>AB TTC was less than 300 MW 4% of the hours.

TotalTTC_BC_AB.gif

The TTC on the X axis represents TTC after deducting applicable TRM.

BCTC also provides similar information on the AB>BC path.

TotalTTC_AB_BC.gif

Again, the TTC on the X-axis represents TTC after deducting the applicable TRM.

While the statistics on the BC>AB path support BCTC’s Firm TTC, the statistics on the AB>BC path suggest that limits in Real-time tend not to reach BCTC’s levels of Firm TTC. For example, TTC was less than 235 MW 48% of the hours.

Our analysis shows that in approximately 80% of the hours in the period analyzed the AESO was the limiting control area.

BCTC will re-examine its approach on AB>BC Firm TTC and advise the market by Friday July 30, 2004.

Please contact Mark Prosperi-Porta at (604) 699-7385 for more information or if you have any questions/comments.

Bulletin - TTC on the BC-Alberta Intertie

Posted on June 28 , 4:06 p.m.

On May 28, BCTC posted a bulletin advising customers that effective August 1, 2004, new Firm TTC limits would be in effect. In particular, the Firm TTC limit on the BC > AB path increases from 210 MW to 545 MW. In addition, BCTC posted a System Impact Study on June 28, 2004 regarding the OASIS No. 485180 concluding Long-Term Firm Point-to-Point Transmission Service is available on the BC > AB path.

BCTC analyzed hourly TTC on the BC > AB path during the January 1, 1999 - June 1, 2004 period. Although Real-time TTC on the BC>AB path may be less than 480 MW (545 MW - 65 MW TRM) at times due to system conditions, BCTC found that 93% of the hours had hourly TTC, after accounting for TRM, greater than 480 MW. This data supports BCTC’s 545 MW Firm TTC based on the methodology in Section 2.2.4 of the Business Practices.

For more information or any questions, please call Mark Prosperi-Porta at (604) 699-7385.

BCTC is currently experiencing problems with its E-tag service, effective May 29, 2004 @ 04:30 PDT. As a result, backup procedures will be in effect for Real-time and Pre-schedule until the E-tag service is restored. A subsequent bulletin will be posted when normal procedure can be followed.

Amended Business Practices - Section 2, TTC/ATC

Posted on May 28 , 4:55 p.m.

Business Practice Section 2, TTC/ATC, is amended to reflect a new Firm TTC limit on the BC>AB path.

The bulk transmission between BC and Alberta is through one radial 500 kV line consisting of 5L92 (Selkirk Substation to Cranbrook Substation) and 5L94. Although, outages to either of 5L92 and 5L94 are not considered, limits encountered under system normal are considered when determining the Firm TTC from BC to Alberta.

The transfer capability after the loss of 5L91 (Ashton Creek Substation to Selkirk Substation) or 5L98 (Nicola Substation to Selkirk Substation) or with all elements in service (system normal) defines the Firm TTC from BC to Alberta. The Firm TTC is 545 MW.

BCTC will increase the Firm TTC limits in Pre-schedule and Real-time to be consistent with those in the business practices. These Firm TTC limits will take effect on August 1, 2004.

A summary of the current and future Firm TTC limits are described in the following table:

Path	Current Firm TTC	Firm TTC Effective August 1, 2004
AB>BC	150 MW	300 MW
BC>AB	210 MW	545 MW
BC>US	1800 MW	1800 MW
LM>US	1800 MW	1800 MW
US>BC	1400 MW	1800 MW

These Firm TTC limits are regularly updated to reflect operating conditions.

Please contact Mark Prosperi-Porta at (604) 699-7385 for more information.
