California ISO Conformed Tariff as of February 14, 2005

The Tariff is current through February 14, 2005. Currently effective language from Tariff Amendments and compliance filings which FERC has approved is shown in clean copy. Pending language from compliance filings that FERC has not ruled on as of February 14, 2005, but whose proposed effective date has already arrived, is shown in highlight.

Note that where such pending compliance filing language will supersede currently approved language, it will be necessary to consult previous versions of the Tariff to see the full text of the language superseded by the highlighted pending language.

The Tariff does not include Tariff Amendments submitted to the Commission but not yet approved.

This version updates the November 29, 2004 version of the Conformed Tariff to reflect:

• FERC’s acceptance of tariff changes proposed in the ISO’s July 29, 2004 filing of an offer of partial settlement in the 2004 Grid Management Charge (GMC) proceeding, in an Order issued February 2, 2005 (see Order Approving Uncontested Partial Settlement, 110 FERC 61,273). The approved language can be found on pages 217, 217A, 217A.01, 217A.02, 217A.03, 217B, 218, 308A, 314A, 319, 333A, 373 through 376I, 641, 643, and 647.

• FERC’s December 21, 2004 Order in the Transmission Access Charge (TAC) proceeding (see Opinion No. 109 FERC 61,301 at PP 103-107) which dismissed as moot changes to the definition of “Gross Load” proposed by the ISO in a Compliance Filing on July 25, 2003.

The approved language, which was previously shown in highlight, can be found on pages 204, 204B, 204C and 204D; the proposed language from the February 14 Compliance Filing with a current proposed effective date is shown in highlight on page 204A.01.

• New tariff Section 3.1.4 proposed in the ISO’s January 10, 2005 Compliance Filing in Docket No. ER04-688. The proposed language is shown in highlight on page 141. [This page is contained in the PDF document below numbered 03, as well as in the Combined Tariff PDF document];
• FERC’s Acceptance of Tariff Amendment No. 64 in Order issued January 28, 2005, (see 110 FERC 61,082) with required modifications as made by the ISO in a compliance filing on February 14, 2005. The Amendment 64 language can be found on page 247.03, with the pending compliance filing change shown on that page in highlight. [This page is contained in the PDF document below numbered 04, as well as in the Combined Tariff PDF document];

Page 184.E01 reflects the deletion of the section. [This page is contained in the PDF document below numbered 03, as well as in the Combined Tariff PDF document.]

  On March 29, 2005, the ISO posted the Dynamic Scheduling Protocol as filed with and accepted by FERC, to replace the near-final draft of the Protocol that had been inadvertently posted previously.

  Following the Tariff itself, a supplementary section is provided, Tab 1, which includes language, proposed in the ISO’s February 14, 2005 Compliance Filing in the Amendment 50 docket, which is not effective as of February 14, 2005. The additions proposed in this pending compliance filing are shown in highlight.
