FERC Denies Request for Rehearing on Order No. 810 - September 1 - FERC denied a request for clarification or rehearing of Order No. 810 by Powerex Corporation.  In Order No. 810, FERC approved Reliability Standard BAL-001-2, which determines Balancing Authority ACE Limits for a balancing authority’s ACE value limits as a function of Interconnection frequency.  Powerex asserted that the Order does not provide sufficient assurance that market participants will have enough information about ACE imbalances to identify possible exploitation of Reliability Standard BAL-001-2 by balancing authorities.  FERC determined that there was no evidential support for exploitation by balancing authorities.

FERC Accepts NERC Filing on SPP Bylaws - September 1 - FERC accepted NERC’s uncontested filing relating to its proposed amendments to Southwest Power Pool’s (SPP) bylaws, specifically to Exhibit B of the Delegation Agreement.  Requests for rehearing by the Commission may be filed within 30 days of the letter order accepting NERC’s filing.


NERC Submits Errata to Petition for Approval of Amendments to Delegation Agreement - September 3 - NERC submitted an errata to its proposed Amendments to Exhibit B to the Delegation Agreement with the Midwest Reliability Organization, Inc. (MRO), originally submitted by NERC on August 14.  In the errata, NERC addresses an error in the “Redline” version of the Bylaws and the deletion of language in Section 2.1 of the Bylaws.

NERC Penalty Activity - August 31 - NERC filed with FERC a spreadsheet notice of penalty resolving 1 violation of a Reliability Standard.

Errata to Petitions of NERC for Approval of Reliability Standards - August 25 - NERC submitted to FERC errata to Reliability Standards BAL-003-1, COM-001-2, VAR-001-4, and to the Implementation Plan for PRC-004-4.  The filing corrects minor formatting and stylistic errors as well as language clarifications to the already filed and approved Reliability Standards.

DOE Releases Annual Transmission Data Review – August 27 – The Office of Electricity Delivery and Energy Reliability released its Annual U.S. Transmission Data Review, focusing on transmission infrastructure, transmission reliability, transmission utilization, transmission constraints, economic congestion, and transmission planning.  The report uses data from NERC’s Severity Risk Index (SRI), a composite metric measuring generation loss, transmission loss, and load loss, as well as 18 other metrics to establish an “Adequate Level of Reliability.”  The report analyses daily SRI values from 2008-2013.
