Reference:   Errata to Letter Order Issued November 14, 2012 Dear Mr. Sweeny:

On November 14, 2012, the Commission issued a letter order in the above proceeding to the New York Independent System Operator, Inc.

The proxy bus for intra-hour (i.e., 15-minute) transaction scheduling was

incorrectly identified as the Keystone bus in the Reference line of the letter.  The

Reference line should have indicated the Neptune proxy bus as indicated in the body of the letter.

Sincerely,

Jignasa Gadani, Director Division of Electric Power Regulation - East
