California ISO Conformed Tariff as of January 12, 2006

IMPORTANT NOTE:

California ISO Conformed Tariff as of January 12, 2006

The Tariff is current through January 12, 2006. 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 January 12, 2006, 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approved language, it will be necessary to consult previous versions of the Tariff to see the full text of the language superseded by the highlighted pending language.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 September 21, 2005 version of the Conformed Tariff to reflect:

It should also be noted that there are two supplementary Tabs accompanying this Conformed Tariff which contain language which, although accepted by FERC, has not yet gone into effect.

Tab 2 shows language accepted but not yet effective from Amendment 68 regarding Station Power.
