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:
The most recent update to these tariffs reflects the Commission Order issued September 9, 2014 accepting the November 26, 2013 filing in Docket No. ER14-473-000 to comply with Order No. 784 that required transmission providers to amend their tariffs to include a statement that the public utility transmission provider “will take into account the speed and accuracy of regulation resources in determining reserve requirements for Regulation and Frequency Response Service, including whether a self-supplying customer has made alternative comparable arrangements.”
