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.

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.
