Miscellaneous Information

BPA's reliability coordinator, Peak Reliability, has adopted a new methodology for calculating System Operating Limits (SOL) within WECC's Western Interconnection. The new methodology considers facility ratings and changes in topology configuration that can no longer be expressed in a single data point. As a consequence, effective April 1, 2017, SOLs will no longer be published in charts and data tables. Click for FAQ. Please visit if you have questions about the new SOL methodology.

Note: BPA monitors system conditions and provides mitigation as needed per appropriate reliability issues and NERC standards.
