Attention:David Allen, Senior Attorney
New York Independent System Operator, Inc.
Reference: Tariff Revisions Dear Mr. Allen:
On March 26, 2010, New York Independent System Operator, Inc.
(NYISO) filed revised tariff sheets1 with proposed revisions to both its Market
Administration and Control Area Services Tariff and its Open Access
Transmission Tariff (collectively “NYISO’s Tariffs”) to clarify certain meter data
posting and customer review timelines in the provisions in NYISO’s Tariffs for
billing and payment. Specifically, NYISO has revised both NYISO Tariffs to: (1)
clarify what meter data will be used for invoices, and reserving the right to use
estimates to settle an invoice (NYISO’s Tariffs already allowed use of estimates in
whole or in part, now the language states “in accordance with ISO Procedures);
and (2) increased times for ISO posting of LSE bus metering data from 71 to 75
days, ISO posting of updated and corrected LSE bus metering data from 131 to
135 days, and decreased customer review and challenge time from 14 to 10 days.
1 Second Revised Sheet Nos. 80, 83.01G(1) and 83.01G(2) to New York
Independent System Operator, Inc., FERC Electric Tariff, Original Volume No. 1, and Second Revised Sheet Nos. 188 and 191.01C(2) to New York Independent System Operator, Inc., FERC Electric Tariff, Original Volume No. 2.
