Proposed Change to Counterflow
Posted on April 30, 9:40 a.m.
Overview
BC Hydro Transmission Provider received a request from BC Hydro Power Supply (BCPS) to make changes to the TTC/ATC Business Practice and the ATC Implementation Document. BCPS’ proposal is as follows in this bulletin. Please provide your feedback on the proposed change, and why you do or do not support it to Brenda Ambrosi by end of business day on May 17. BC Hydro Transmission Provider may post the verbatim comments received by stakeholders.
CUSTOMER PROPOSAL
BC Hydro Power Supply (BCPS) requests that BC Hydro Grid Operations (Transmission Provider) modify BC Hydro’s ATC Implementation Document (ATCID) and associated TTC/ATC Business Practice to allow for firm counter-flow scheduling from BC to the U.S. based on the assured deliveries of the Canadian Entitlement.
Background:
The Canadian Entitlement is a firm generation resource that is delivered to BC Hydro from the U.S. using firm transmission under the Columbia River Treaty. BC Hydro, as the Canadian Entity for the Columbia River Treaty, has knowledge and visibility of the Canadian Entitlement, including the timing and volumes of the assured deliveries.
BCPS has a firm import transmission reservation on the Transmission System associated with the Canadian Entitlement under OASIS AREF # 80049172. This transmission reservation allows for the scheduling of the Canadian Entitlement from the US to BC Hydro.
Under BC Hydro’s TTC/ATC Business Practice, Section 5.2, BCPS notifies the Transmission Provider in the preschedule horizon of the required transmission for the next-day Canadian Entitlement deliveries. The release of any unscheduled transmission capacity is incorporated into BC Hydro’s Firm ATC formulas in Section 3.0 of the TTC/ATC Business Practice. In addition, the TTC/ATC Business Practice allows for counter- flows to be added to the ATC calculation, but only on a non-firm basis, including for Canadian Entitlement counter-flows.
Proposal:
BCPS proposes that the Transmission Provider take into consideration the nature of the Canadian Entitlement and its assured deliveries of prescheduled energy, and incorporate those schedules as counter-flows into the determination of firm ATC on the export path to the US Border.
Currently, the ATCID (Section 5.1.4) and TTC/ATC Business Practice (Section 4) do not consider firm deliveries for counter-flow purposes on a firm basis. However, Attachment C of the Open Access Transmission Tariff (section 2) expressly allows for the Transmission Provider to incorporate firm counter-flows as part of its Firm ATC formula. Counter-flows should only be considered firm if there is an assured delivery of a firm generating resource on firm transmission from source to sink with full visibility to the Transmission Provider. BCPS believes the Canadian Entitlement deliveries meet these criteria.
Accordingly, BCPS requests that the Transmission Provider recognize Canadian Entitlement deliveries as firm counter-flows, and modify the TTC/ATC Business Practice and ATCID documentation to allow Canadian Entitlement counter-flow deliveries to increase firm ATC on the export path to the U.S. border.
BCPS does not expect that this change would negatively affect other Transmission Customers.
