Reference: TCC Market Revisions to Open Access Transmission Tariff and Market
Services Tariff

Dear Ms. Lampi:

New York Independent System Operator, Inc.’s (NYISO) submittals are accepted for filing effective May 31, 2010, as requested and as designated.1

On March 31, 2010, as amended on April 16, 2010 and on April 27, 2010, NYISO
filed tariff revisions to its Open Access Transmission Tariff (OATT) and its Market
Services Tariff (Services Tariff) to revise provisions concerning the Transmission
Congestion Contracts (TCC) market. NYISO states that the revised tariff sheets
reorganize and clarify tariff provisions that govern the TCC market and eliminate
redundancy between the OATT and Services Tariff. NYISO states that the revised tariff
sheets make no substantive changes to tariff provisions or current practices concerning
the TCC market. The revised tariff sheets revise provisions in Section 1, Attachment M
and Attachment N of the OATT. NYISO has also proposed changes to Section 7 and
Attachment B of the Services Tariff.

Notice of the filings was issued on April 1, 2010, April 19, 2010, and April 28,

1 See attached Appendix.
