Info

• Serve as a complete list of all path information, or • Enforce, support or implement any WECC Policy. Contents This Path Rating Catalog should include: • All significant paths (i.e., Loop Flow Qualified paths, OTC Policy Group paths and constrained paths), • A compilation of best available path rating information consisting of accepted ratings, Phases 2 and 3 ratings, existing ratings and other ratings, • The names of contact persons of the appropriate WECC members (single point of contact), • “Maximum Path Transfer Capabilities,” not “First Contingency Incremental Transfer Capabilities” and reflects technical transfer capabilities based on technical limits from system planning studies. Path Descriptions The minimum specific content of each path description should include: • A specific identification of the facilities that make up the transmission path, including the location of applicable metering points. • A discussion of the non-simultaneous path rating and the conditions used to achieve the path rating, • Any necessary Remedial Action Schemes to achieve the path rating, • An identification of interactions or relationships with other paths including applicable nomograms (Information should be provided on where a “current” nomogram can be located), • Ownership and allocation or rights on the path, • Date of submittal or update and contact person. Additional explanatory information supporting transfer path ratings is welcome such as identification of internal paths that are considered to have no significant regional impact. Document Update Policy Changes to an “accepted” or “existing” path rating must follow the WECC Project Coordination and Path Rating Processes (WECC Procedures). Minor changes to a path rating (such as moving a metering location) should be submitted as part of the 60-day Expedited Process defined in Section 3.3 (pages 41-42) of the WECC Procedures (assuming no comments require reissuing a study report). Changes to a path with an “other” path rating do not need to follow the WECC Procedures; however, the path will retain the “other” status. Changes to an “accepted” or “existing” path rating that do not follow the WECC procedures will be reclassified to “other” status. Although updated entries to the WECC Path Rating Catalog may be submitted to the WECC staff at any time, the catalog will be published once annually. Each path rating narrative shall indicate the date it was added to the catalog. When a path rating narrative is revised, the word “Revised” will be added followed by the revision date. Paths can be deleted if superseded by another path with newly defined accepted rating or with notification and explanation to TSS. Prior to a member system submitting additions or changes to the WECC Path Rating Catalog to WECC, it shall notify and coordinate these additions and/or changes with other WECC members PART VI Item 1- ii
holding rights on the path. Additions or changes to the WECC Path Rating Catalog will be solicited, compiled, and distributed by the WECC staff prior to January 1 st for review and comment by the Technical Studies Subcommittee. Members having any concerns with the content of a proposed submittal shall seek resolution with the member making the submittal. If resolution is not reached prior to the publication of the document, the member’s concerns should be outlined in the appropriate narrative section submitted by the submitting member. WECC Procedures Prior to August 1991, project ratings for new facilities were defined using the Annual Progress Reporting Procedure. In August 1991, the Notification Procedure for Changes in Facility Ratings and/or Operating Procedures was adopted for documenting up-rates in existing facilities. This augmented the Annual Progress Reporting Procedure. In November of 1992, the Policies and Procedures for Rating Transmission Facilities was adopted which added a formal review process for checking the proposed non-simultaneous rating and simultaneous operating problems of the new or existing path being rated. In November of 1993, the Interim Procedures for Regional Planning Project Review and Rating Transmission Facilities were adopted to address issues related to Regional Transmission Planning. This new procedure incorporated into it the Policies and Procedures for Rating Transmission Facilities of November 1992. The final version, called Procedures for Regional Planning Project Review and Rating Transmission Facilities, was approved in March 1995. In March of 1996, the procedures were further enhanced and are included in the WECC Procedures for Regional Planning Project Review and Rating Transmission Facilities. In March of 2000 the TSS revised the introduction for clarity. This change included improved procedures for adding (removing) paths to (from) the Catalog. In August 2004 the TSS revised the Path Rating Catalog document update policy to include procedures for making minor changes to path ratings. In March 2005, the WECC Procedures for Regional Planning Project Review, Project Rating Review, and Progress Reports were adopted to address issues related to recent changes in the electric power industry. Additionally, in April 2005 the TSS revised the Path Rating Catalog to include metering points on path descriptions. Explanation of Rating Categories as Used in this Catalog • Accepted Rating A project rating that has been reviewed and accepted by WECC members. This rating is granted by WECC at the conclusion of reviewed planning studies and will be the rating of the project when it is put in service, if it is built per specification. This is a comprehensive rating including both the simultaneous and non-simultaneous transfer capabilities. (Reference: Procedures for Regional Planning Project Review and Rating Transmission Facilities.) • Existing Rating Transmission path ratings that were known and used in operation as of January 1, 1994. (Reference: Procedures for Regional Planning Project Review and Rating Transmission Facilities.) • Other A transmission path rating, either proposed or planned, that is not an accepted or existing rating.
