The NYISO tariffs are updated on or about the effective date listed in a FERC order. The following note is revised with each tariff update to show the related order date, filing date, docket number, and effective date:
On March 3, 2014 and April 10, 2014, the Commission issued orders accepting tariff revisions filed December 27, 2013 and March 13, 2014 in Docket Nos. ER14-864-000 and ER14-864-001, and effective April 8, 2014. The tariff update to show the currently effective language has been delayed, however, due to complexities created by the existence of other accepted but not yet effective language within some of the relevant tariff sections. This delay does not impact the effective date of the Commission orders.
The most recent update to these tariffs reflects the Commission Order issued March 20, 2014 accepting proposed language filed November 12, 2013, and effective January 15, 2014, under Docket No. ER14-385-000.
