2 Balancing Authority ACE Limit Proof-of-Concept Field Trial Eastern Interconnection Field Trial Participation Participation reflects approximately 67% of the projected 2010 peak load for the Eastern Interconnection

3 Balancing Authority ACE Limit Proof-of-Concept Field Trial The Balancing Authority ACE Limit (BAAL) shall not be exceeded for more than 30 consecutive clock-minutes* MinCtLow = Count of consecutive clockminutes BAAL Low was exceeded MinCtHigh = Count of consecutive clockminutes BAAL High was exceeded ** *BAAL being exceeded for more than 30 consecutive clock-minutes would be a violation under the proposed BAL-007 standard.

4 Frequency Statistics Eastern Interconnection This chart is a summary of frequency-related statistics gathered since the start of the Field Trial. Of particular interest is the drop in operation outside of the FTL bounds, trending lower in the latter part of 2008 with November 2008 having the least number of clock-minutes of operation outside the FTL bounds, followed by August 2009, over the dataset.
