Modification of Interchange and Transmission Loading Relief 
Reliability Standards; and Electric Reliability Organization 
Interpretation of Specific Requirements of Four Reliability Standards

May 16, 2008.
AGENCY: Federal Energy Regulatory Commission, DOE.

ACTION: Supplemental Notice of proposed rulemaking.

-----------------------------------------------------------------------

SUMMARY: On April 21, 2008, the Commission issued a Notice of Proposed 
Rulemaking (NOPR) that proposes, inter alia, to approve interpretations 
of specific requirements of Commission-approved Reliability Standards 
submitted to the Commission for approval by the North American Electric 
Reliability Corporation (NERC).

[[Page 30327]]

Pursuant to section 215 of the Federal Power Act (FPA), the Commission 
supplements the NOPR by proposing to approve NERC's modified 
interpretation of Reliability Standard BAL-005-0 (Automatic Generation 
Control), Requirement R17.

DATES: Comments for this Supplemental Notice of Proposed Rulemaking are 
due June 12, 2008, concurrent with the comment due date for the NOPR 
issued on April 21, 2008.

ADDRESSES: You may submit comments, identified by docket number by any 
of the following methods:
     Agency Web Site: http://www.ferc.gov. Documents created 
electronically using word processing software should be filed in native 
applications or print-to-PDF format and not in a scanned format.
     Mail/Hand Delivery. Commenters unable to file comments 
electronically must mail or hand deliver an original and 14 copies of 
their comments to: Federal Energy Regulatory Commission, Secretary of 
the Commission, 888 First Street, NE., Washington, DC 20426.

Supplemental Notice of Proposed Rulemaking

May 16, 2008.
    1. On April 21, 2008, the Commission issued a Notice of Proposed 
Rulemaking (NOPR) that proposes, inter alia, to approve interpretations 
of specific requirements of Commission-approved Reliability Standards 
submitted to the Commission for approval by the North American Electric 
Reliability Corporation (NERC).\1\ Pursuant to section 215 of the 
Federal Power Act (FPA),\2\ the Commission supplements the NOPR by 
proposing to approve NERC's modified interpretation of Reliability 
Standard BAL-005-0 (Automatic Generation Control), Requirement R17.

I. Background

A. Regulatory History

    2. On December 19, 2007, NERC submitted for Commission approval 
interpretations of requirements in four Commission-approved Reliability 
Standards, including an interpretation of BAL-005-0, Requirement 
R17.\3\ On April 15, 2008, NERC submitted a request to withdraw the 
interpretation of Requirement R17 and substitute a revised 
interpretation of the same requirement (referred to by NERC as 
``interpretation (b)'').
---------------------------------------------------------------------------

    \3\ The Commission approved BAL-005-0 in Order No. 693. 
Mandatory Reliability Standards for the Bulk-Power System, Order No. 
693, 72 FR 31,452, FERC Stats. & Regs. ] 31,242, at P 396 (2007), 
order on reh'g, Order No. 693-A, 120 FERC ] 61,053 (2007).
---------------------------------------------------------------------------

    3. On April 21, 2008, the Commission issued a NOPR in this 
proceeding. In the NOPR, the Commission noted that NERC submitted a 
modified interpretation of BAL-005-0 on April 15, 2008. The Commission 
stated that it did not plan to act on the initial interpretation and 
would address ``interpretation (b)'' at a future time.

B. NERC's Proposed Interpretation

    4. Requirement R17 of Reliability Standard BAL-005-0 obligates each 
balancing authority to ``at least annually check and calibrate its time 
error and frequency devices against a common reference.'' This is one 
aspect of ensuring the accurate calculation of area control error 
(ACE). Requirement R17 states that a balancing authority must adhere to 
minimum accuracies in terms of ranges for the following devices: 
Digital frequency transducer, voltage transducer, remote terminal unit, 
potential transformer, and current transformer.
    5. NERC received a request for interpretation regarding the type 
and location of the equipment to which Requirement R17 applies. In 
response, a NERC task force developed, and the NERC board of trustees 
approved, interpretation (b), which provides that BAL-005-0, 
Requirement R17

applies only to the time error and frequency devices that provide, 
or in the case of back-up equipment may provide, input into the 
reporting or compliance ACE equation or provide real-time time error 
or frequency information to the system operator. Frequency inputs 
from other sources that are for reference only are excluded. The 
time error and error frequency measurement devices may not 
necessarily be located in the system operations control room or 
owned by the Balancing Authority; however the Balancing Authority 
has the responsibility for the accuracy of the frequency and time 
error devices. * * *
New or replacement equipment that provides the same functions noted 
above requires the same calibrations. Some devices used for time 
error and frequency measurement cannot be calibrated as such. In 
this case, these devices should be cross-checked against other 
properly calibrated equipment and replaced if the devices do not 
meet the required level of accuracy.

II. Discussion

    6. The Commission proposes to approve NERC's interpretation (b) of 
BAL-005-0, Requirement R17. The Commission agrees that, as stated in 
interpretation (b), time error and frequency devices that serve as 
input into the reporting or compliance of the ACE equation, whether 
inside or outside the operations control room, must be annually checked 
and calibrated. In addition, the Commission notes that tie-line 
megawatt metering data is another important aspect of ensuring the 
accurate calculation of area control error (ACE), and interpretation 
(b) limits the specific accuracy requirements of Requirement R17 to 
frequency and time error measurement devices. We seek comment on 
whether interpretation (b): (1) Could decrease the accuracy of 
frequency and time-error measurements by not requiring calibration of 
tie-line megawatt metering devices; (2) what conditions would preclude 
the requirement to calibrate these devices; and (3) whether the 
accuracy of these devices is assured by other requirements within BAL-
005-0 in the absence of calibration.

III. Comment Procedures

    7. The Commission invites interested persons to submit comments on 
the matters and issues proposed in this notice to be adopted, including 
any related matters or alternative proposals that commenters may wish 
to discuss. Comments are due June 12, 2008, concurrent with the comment 
due date for the NOPR issued on April 21, 2008. Comments must refer to 
Docket No. RM08-7-000, and must include the commenter's name, the 
organization they represent, if applicable, and their address in their
