I'm still looking to see if the changed this requirement or what the outcome of what is suggested below.

Initially the investor-owned > utility (IOU) Control Centers and ICCP links were utilized on an interim > basis to provide this capability, until the ISO could establish the > communications links that would facilitate direct communications to the > Generating Units. This communication link is vital for all resources, > including Generating Units and loads that provide Ancillary Services (A/S) > to the ISO. The ISO and Market Participants began the Generator > Communications Project in 1998 to develop standards, equipment, and > communications protocols to provide this link. The initial focus was on > Generating Units providing Regulation. Generating Units that provide > Regulation to the ISO must have a Remote Intelligent Gateway (RIG) unit, > which provides the ISO direct AGC control of the Generating Unit as well > as direct communication. (The RIG installation at those units satisfies > the requirements of this Notice.) > > With that phase of the installation almost complete, the > next phase of the program has started to establish the communications > links for all resources providing Ancillary Services. (Currently Loads > greater than 1 MW can provide Ancillary Services and Generating Units over > 10 MW can provide A/S. The ISO is currently considering lowering the > floor for Generating Units providing Ancillary Services from 10 MW to 1 > MW.) > > This will require all remaining resources providing > Ancillary Services to install by June 1, 2001 an ISO-approved direct > communication system for its affected Generating Unit(s) for telemetry to > the ISO Energy Management System (EMS).

(Of course, Generating Units that provide > Regulation to the ISO must have a Remote Intelligent Gateway (RIG) unit, > which provides the ISO direct AGC control of the Generating Unit as well > as direct communication.) > > As announced initially by the ISO at the February 3, 2000 > Generators' meeting for the ISO's Generator Communications Project (GCP), > and reiterated most recently at the July 20, 2000 GCP meeting, the work > required to install and test the DPG (or ISO-approved alternative > technology) and to undertake re-certification of the capability of the > Generating Unit(s) to provide Ancillary Services to the ISO must be > completed by June 1, 2001.
