See second paragraph. I'm still looking to see if the changed this
requirement or what the outcome of what is suggested below. Keoni Almeida California Independent System Operator phone: 916/608-7053 pager: 916/814-7352 alpha page: 9169812000.1151268@pagenet.net e-mail: <mailto:kalmeida@caiso.com< < -----Original Message----- < From: Happ, Susan On Behalf Of Fuller, Don < Sent: Tuesday, September 26, 2000 8:39 AM < To: GCP - Market Participants; ISO Market Participants < Subject: GCP Phases 2 Requirements Notice < < < Market Participants and GCP Market Participants: < < Since start-up the ISO has been obligated to gain direct < communications access to Generating Units in the ISO Control Area, subject < to existing contractual arrangements. 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). The ISO currently has approved < the Data Processing Gateway (DPG) technology for such direct telemetry. < Thus, each affected Generator and Load must install a DPG for its < Generating Unit(s) or Load(s) that may provide Ancillary Services other < than Regulation unless it requests and receives ISO approval for the use < of an alternative technology. (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. After that date, Generating Units that do not < use the DPG (or other ISO-approved) technology may be precluded from < supplying Ancillary Services to the ISO. < < The ISO will provide a formal notice of the foregoing < requirements by a letter to each Participating Generator. If you have any < questions or concerns about the requirement to install and use a DPG (or < ISO-approved alternative technology), please feel free to call Ernest < Senior of ISO Operations Systems (916-608-5887) or the ISO Client < Representative for the Generator Communications Project, Dave Timson < (916-608-7065). < < < Don Fuller < Director, Client Relations < < < NOTE: In order for the ISO to make appropriate accommodations for the < interconnection between the ISO's EMS and DPGs for all Generating Units < supplying Ancillary Services other than Regulation to the ISO, the ISO < will be requesting that Generators provide an installation schedule < applicable to each affected Generating Unit. We intend to issue the < request for DPG installation schedules by October 10, 2000.
