City of Roseville, FERC Docket No. NP10-2-000 (October 14, 2009)

Reliability Standard: PRC-021-1

Requirement: R2

Violation Risk Factor: Lower

Violation Severity Level: Not provided

Region: WECC

Issue: In June 2007 the City of Roseville self-reported that it could not produce, within 30 days, all of the required Under-Voltage Load Shedding (UVLS) program data since the overall clearing time data was not available while system testing was underway. System testing was not completed until July 2007.

Finding: WECC found that this violation did not involve a serious or substantial risk to bulk power system reliability since the operation of the UVLS was not affected by the reporting of the overall clearing time data. This violation was primarily a documentation issue. Also, the City of Roseville self-reported the violation; this was the City of Roseville’s first violation of this Reliability Standard; and a mitigation plan was completed.

Penalty: $0

FERC Order: Issued November 13, 2009 (no further review)

Plumas-Sierra Rural Electric Cooperative, FERC Docket No. NP10-2-000 (October 14, 2009)

Reliability Standard: PRC-021-1

Requirement: R1

Violation Risk Factor: Lower

Violation Severity Level: Not provided

Region: WECC

Issue: Plumas-Sierra Rural Electric Cooperative (Plumas-Sierra) self-reported that it had not documented its annual update of its Under Voltage Load Shedding (UVLS) program data.

Finding: WECC found that this violation did not pose a serious or substantial risk to the bulk power system since this was primarily a documentation issue. Before becoming registered with NERC, Plumas-Sierra had actually updated its data for the components of its UVLS program (even though it had not documented this update). The violation was self-reported and was Plumas-Sierra's first violation of this Reliability Standard. Even though the violation occurred before the Reliability Standards became mandatory, Plumas-Sierra did not complete its mitigation plan timely manner. This delay turned the violations into a post-June 18, 2007 violation. Even with the late completion of the mitigation plan, no penalty was imposed.

Penalty: $0

FERC Order: Issued November 13, 2009 (no further review)
