WECC 2013 PATH RATING CATALOG January 2013 Prepared By: TECHNICAL STUDIES SUBCOMMITTEE
WECC PATH RATING CATALOG Disclaimer This catalog contains descriptions of path components and describes path ratings as provided by individual WECC members. The path ratings in this catalog are “Maximum Path Transfer Capabilities” and not “First Contingency Incremental Transfer Capabilities” (the method used by other NERC councils). Most of the ratings reflect capabilities based on technical limits determined from system studies. They do not represent Available Transmission Capacity because they do not indicate the degree to which the path transfer capability has been committed with existing transactions. This document is not intended to be used for the purposes of validating the applicability of a path or to determine if WECC procedures were followed to determine its rating. Publication of a path rating in this document does not imply WECC approval of that rating. The appropriate WECC procedures must be followed to achieve formal WECC approval of a path rating. Per WECC procedure, any path rating can be challenged if the reliability criteria are violated. This document is only intended to compile currently available information into a single document. Introduction This WECC Path Rating Catalog contains a collection of discussions on individual path ratings within the WECC system. A path rating can be related to an individual transmission line or a combination of parallel transmission lines. The transfer path may be composed of transmission lines between control areas or internal to a control area, or a combination of both. All information in this Path Rating Catalog was provided, and should continue to be provided on a voluntary basis. From this information, transfer limitations can be identified for regional planning analysis. Identification of path ratings, with supporting information, will assure that any relation between existing ratings and proposed new projects can be identified during a project review process according to the WECC Project Coordination and Path Rating Processes Purpose The Path Rating Catalog compilation of transfer path rating information is intended to: • Be a reference document for planning purposes, • Serve as a primary source of currently available information on maximum, non-simultaneous path ratings to WECC Members, • Provide a resource for discussion of simultaneous interactions between major transmission paths. Among other things, this Path Rating Catalog is not intended to: • Ascertain if WECC Procedures were followed to determine a path rating, • Support regulatory proceedings against a WECC member because of erroneous information, • Imply WECC approval of the rating, although a path can receive an “Accepted Rating” via the Three Phase Rating Process, • Provide OASIS information or Available Transfer Capability (ATC) or the most current operating limits, PART VI Item 1- i

WECC PATH RATING CATALOG<br />
Disclaimer<br />
This catalog contains descriptions of path components and describes path ratings as provided by<br />
individual WECC members. The path ratings in this catalog are “Maximum <strong>Path</strong> Transfer<br />
Capabilities” and not “First Contingency Incremental Transfer Capabilities” (the method used by<br />
other NERC councils). Most of the ratings reflect capabilities based on technical limits<br />
determined from system studies. They do not represent Available Transmission Capacity because<br />
they do not indicate the degree to which the path transfer capability has been committed with<br />
existing transactions.<br />
This document is not intended to be used for the purposes of validating the applicability of a path<br />
or to determine if WECC procedures were followed to determine its rating. Publication of a path<br />
rating in this document does not imply WECC approval of that rating. The appropriate WECC<br />
procedures must be followed to achieve formal WECC approval of a path rating. Per WECC<br />
procedure, any path rating can be challenged if the reliability criteria are violated. This document<br />

Introduction<br />
This WECC <strong>Path</strong> <strong>Rating</strong> <strong>Catalog</strong> contains a collection of discussions on individual path ratings<br />
within the WECC system. A path rating can be related to an individual transmission line or a<br />
combination of parallel transmission lines. The transfer path may be composed of transmission<br />
lines between control areas or internal to a control area, or a combination of both.<br />
All information in this <strong>Path</strong> <strong>Rating</strong> <strong>Catalog</strong> was provided, and should continue to be provided on a<br />
voluntary basis. From this information, transfer limitations can be identified for regional planning<br />
analysis. Identification of path ratings, with supporting information, will assure that any relation<br />
between existing ratings and proposed new projects can be identified during a project review process<br />
according to the WECC Project Coordination and <strong>Path</strong> <strong>Rating</strong> Processes<br />
Purpose<br />
The <strong>Path</strong> <strong>Rating</strong> <strong>Catalog</strong> compilation of transfer path rating information is intended to:<br />
• Be a reference document for planning purposes,<br />
• Serve as a primary source of currently available information on maximum, non-simultaneous<br />
path ratings to WECC Members,<br />
• Provide a resource for discussion of simultaneous interactions between major transmission<br />
paths.<br />
Among other things, this <strong>Path</strong> <strong>Rating</strong> <strong>Catalog</strong> is not intended to:<br />
• Ascertain if WECC Procedures were followed to determine a path rating,<br />
• Support regulatory proceedings against a WECC member because of erroneous information,<br />
• Imply WECC approval of the rating, although a path can receive an “Accepted <strong>Rating</strong>” via<br />
the Three Phase <strong>Rating</strong> Process,<br />
• Provide OASIS information or Available Transfer Capability (ATC) or the most current<br />
operating limits,<br />
