Dear Ms. Lampi:

On September 23, 2014, New York Independent System Operator, Inc. (NYISO) submitted a compliance filing to comply with the requirements of the Commission’s September 9, 2014 Order [1] in this proceeding. The September 9, 2014 Order required NYISO to submit a compliance filing that either (1) provides the location of the information it currently posts and demonstrates that it is consistent with or superior to the requirement of Order No. 784 [2], or (2) specifies the date that it will begin posting Area Control Error data and whether the data will be posted on a six-second or on a one-minute/ten-minute average basis.[3] You state that NYISO will post six-second ACE data for 2013 to its website before the end of October 2014.[4] You further state that NYISO has begun the process of automating a monthly posting of six-second ACE data for the most recently concluded year and the most recently completed month, and this process will be deployed in February 2015. NYISO’s compliance filing satisfactorily complies with the requirements of the September 9, 2014 Order.
