which was submitted yesterday in the above-captioned proceeding, contained a typographical
error.  The NYISO is therefore submitting a corrected List of Reviewing Representatives.

I hereby certify that a copy of this letter and the corrected List of Reviewing Representatives will be served on all parties in this proceeding concurrent with their electronic submission to the Commission.

Respectfully submitted,
