BAL-006-2: Inadvertent Interchange

Purpose
This standard defines a process for monitoring Balancing Authorities to ensure that, over the long term, Balancing Authority Areas do not excessively depend on other Balancing Authority Areas in the Interconnection for meeting their demand or Interchange obligations.

Applicability
Balancing Authorities.

BAL-005-0.2b: Automatic Generation Control

Purpose
This standard establishes requirements for Balancing Authority Automatic Generation Control (AGC) necessary to calculate Area Control Error (ACE) and to routinely deploy the Regulating Reserve. The standard also ensures that all facilities and load electrically synchronized to the Interconnection are included within the metered boundary of a Balancing Area so that balancing of resources and demand can be achieved.

BAL-004-WECC-2: Automatic Time Error Correction

Purpose
To maintain Interconnection frequency and to ensure that Time Error Corrections and Primary Inadvertent Interchange (PII) payback are effectively conducted in a manner that does not adversely affect the reliability of the Interconnection.

Applicability
Functional Entities: Balancing Authorities that operate synchronously in the Western Interconnection.

BAL-002-1: Disturbance Control Performance

Purpose
The purpose of the Disturbance Control Standard (DCS) is to ensure the Balancing Authority is able to utilize its Contingency Reserve to balance resources and demand and return Interconnection frequency within defined limits following a Reportable Disturbance. Because generator failures are far more common than significant losses of load and because Contingency Reserve activation does not typically apply to the loss of load,

BAL-001-1: Real Power Balancing Control Performance

Purpose
To maintain Interconnection steady-state frequency within defined limits by balancing real power demand and supply in real-time.

Applicability
Balancing Authorities

Effective Date
The WECC Regional Variance to NERC Reliability Standard BAL-001-1 is to be effective on the first day of the second quarter,
