Purpose: To require sufficient Frequency Response from the Balancing Authority (BA) to maintain Interconnection Frequency within predefined bounds by arresting frequency deviations and supporting frequency until the frequency is restored to its scheduled value. To provide consistent methods for measuring Frequency Response and determining the Frequency Bias Setting.
On February 14, 2025, the Regulatory Commission of Alaska (RCA) issued Order No. E-25-001, suspending Matter No. TE8-9001—which includes the filing of RRC-BAL-003-1, RRC-INT-006-1, RRC-VAR-001-1, and RRC-VAR-002-1—into RCA Docket No. E-25-001.
On December 31, 2024, the RRC filed four proposed reliability standards with the Regulatory Commission of Alaska (RCA) under Matter No. TE8-9001: Frequency and Response Bias (RRC-BAL-003-1), Evaluation of Interchange Transactions (RRC-INT-006-1), Voltage and Reactive Control (RRC-VAR-001-1), and Generator Operations for Maintaining Network Voltage Schedules (RRC-VAR-002-1).
The TAC Recommendation Submittal Package for the Frequency Response and Bias (RRC-BAL-003-1), Evaluation of Interchange Transactions (RRC-INT-006-1), Voltage and Reactive Control (RRC-VAR-001-1), and Generation Operation for Maintaining Network Voltage Schedules (RRC-VAR_002-1) standards, each developed by Working Groups led by the RRC’s Chief Technical Officer. This package was noticed on November 11, 2024, and was acted upon by the Board on December 2, 2024.
Materials for the Frequency Response and Bias (RRC-BAL-003-1), Time Error Correction (RRC-BAL-004), Automatic Generation Control (RRC-BAL-005-1), Inadvertent Interchange (RRC-BAL-006), and Evaluation of Interchange Transactions (RRC-INT-001-1) Working Group meetings.
The Notice of Change to Development Scope of the Batch 1 Reliability Standards development. Automatic Generation Control (RRC-BAL-005-1) is no longer included as part of the Batch 1 Reliability standards development suite.
The schedule of development for Frequency Response and Bias (RRC-BAL-003-1) standard.
The Notice of Intent to develop the Frequency Response and Bias (RRC-BAL-003-1), Time Error Correction (RRC-BAL-004), Automatic Generation Control (RRC-BAL-005-1), Inadvertent Interchange (RRC-BAL-006), and Evaluation of Interchange Transactions (RRC-INT-001-1) standards.
