Notice of Tariff Change 

[                                         ]

	Take notice that on January 28, 2000, the California Independent System Operator Corporation (ISO) tendered for filing a proposed amendment (Amendment No. 26) to the ISO Tariff.  Amendment No. 26 modifies procedures governing the notice provided by the ISO to Scheduling Coordinators that a specific Reliability Must-Run (“RMR”) Unit will be required to provide Energy for reliability purposes during the next day.  The ISO states that the amendment is intended to eliminate market distortions and operational problems that are caused by the current timing of notices.  The amendment also includes modifications of the requirements for scheduling RMR units and of the procedures for the selection of payment options for the Energy provided that the ISO states are necessary to achieve the intended purpose of the modification in timing.

	The ISO states that this filing has been served upon the Public Utilities Commission of California, the California Energy Commission, the California Electricity Oversight Board, the owners of RMR Units, and all parties with effective Scheduling Coordinator Service Agreements under the ISO Tariff.  The ISO also states that the tariff amendments were presented to the owners of RMR Units more than 10 business days before the filing of Amendment No. 26.

	Any person desiring to be heard to protest said filing should file a motion to intervene or protest with the Federal Energy Regulatory Commission, 888 First Street, N.E., Washington, D.C. 20426, in accordance with Rules 211 or 214 of the Commission’s Rules of Practice and Procedure (18 C.F.R. §§ 385.211, 385.214).  All such motions or protests should be filed on or before [                   ].  Protests filed with the Commission will be considered by it in determining the appropriate action to be taken but will not serve to make the protestants parties to the proceeding.  Any person wishing to become a party must file a motion to intervene.  Copies of this filing are on file with the Commission and are available for public inspection.
