US Tie – Change in Curtailment Procedures

Posted on June 28 , 4:41 p.m.

In the bulletin posted May 30 at 11:35 a.m. we solicited customer comments on our curtailment procedures regarding the US tie (BC<>US). We received comments from three customers, all of whom supported BCTC changing its curtailment procedure. Therefore, BCTC will not be curtailing the US tie in pre-schedule, but will wait until real-time to curtail between XX:00 and XX:10 once TTC/ATC are verified. Curtailments will also be performed in real-time at XX:40, if required. This change in procedure will be effective June 30, 2006 for pre-schedule and July 1, 2006 for real-time.

The customer comments received are as follows:

There is no point in curtailing in pre-schedule unless you are sure that there is not going to be any TTC/ATC in real-time. Curtailing in pre-schedule reduces the value of higher priority transmission that has already been purchased. Curtailing in real-time makes more sense. Higher priority transmission customers still maintain their scheduling rights over Hourly Non-Firm, which is why they made the decision to make a longer term commitment.

In response to BCTC's call for customer comments, posted May 30, 2006, we support BCTC changing curtailment procedures on the US-BC intertie to Option 2, consistent with current practices on the AB-BC intertie. We support both ties being operated and cut in a consistent manner.

Based on BCTC's current systems and procedures, we support the proposal of changing the curtailment procedure on the US tie so that curtailments are NOT done in pre-schedule, similar to what is done with the Alberta tie. In implementing this procedure BCTC should still make their customers aware, in pre-schedule, of any expected real-time cuts. We support this procedure for the following reasons: BCTC does not reinstate transmission rights for their customers if the transmission becomes available again after it has already been curtailed; Alberta is a real-time only market and the transmission does not require pre-schedule curtailments; the adjacent control area at the US Border does not curtail their side of the tie in pre-schedule. If BCTC develops the ability to reinstate transmission rights we recommend BCTC reconsider curtailing in pre-schedule.

Thanks to all customers who provided feedback. Please contact Brenda Ambrosi if you have any questions.

US Tie Curtailment Procedures - Soliciting Customer Comments

Posted on May 30 , 11:35 a.m.

The bulletins posted on January 7, 2005 at 11:40 am and January 25, 2005 at 9:33 am solicited customer feedback and confirmed the Alberta Curtailment Procedures, respectively. The procedure was changed to assist customers in retaining their transmission from pre-schedule to real-time. Now, BCTC is soliciting customer comments regarding the Curtailment Procedures on the US Tie. The change in US Curtailment Procedures will provide BCTC and its customers with consistent curtailment application on both interties, and should also assist customers in retaining their transmission from pre-schedule to real-time.

Therefore, we ask customers to provide their comments to brenda.ambrosi@bctc.com on the following two items by noon on Monday, June 12.

1. Shall we leave our curtailment procedures status quo for the US tie, which is to curtail in pre-schedule?

2. Should we change our procedure so that curtailments for the US tie are NOT done in pre-schedule, but rather left until real-time to be curtailed between XX:00 and XX:10 once TTC/ATC are verified? Curtailments will also be done at XX:40, if required.

Shortly after receiving customer comments, we will post another bulletin that will set out these comments received on this issue and which procedure we will follow.
