II.	BACKGROUND

On November 10, 1999, the California Power Exchange Corporation (“PX”) tendered for filing with the Commission proposed Original Sheet No. 81A of its FERC Electric Service Tariff No. 2, which is intended to make permanent a modification of the PX’s Hour-Ahead Market that began on January 17, 1999, as a “Day-of Market Experiment.”
The PX is a nonprofit corporation authorized by FERC order and California electric restructuring legislation and charged with providing a Day-Ahead forward market for energy in accordance with the PX Tariff.  The PX is independent from the ISO and is certified as a Scheduling Coordinator under the ISO Tariff. 
III.	BASIS FOR MOTION TO INTERVENE
The ISO is a non-profit public benefit corporation organized under the laws of the State of California and responsible for the reliable operation of a grid comprising the transmission systems of Pacific Gas and Electric Company, San Diego Gas & Electric Company, and Southern California Edison Company, as well as for the coordination of the competitive electricity market in California.  As part of this responsibility, the ISO implements schedules submitted by Scheduling Coordinators certified by the ISO, including the PX.  The practices of the PX have been designed to “mesh seamlessly” with those of the ISO. The ISO therefore has an interest in this proceeding that cannot adequately be represented by any other party.  Accordingly, the ISO requests that it be permitted to intervene herein with full rights of a party.
The ISO raises no substantive issues at the present time but reserves the right to do so in any further aspects of the proceeding ordered by the Commission.   The ISO also reserves the right to file supplemental comments if warranted.

IV.	CONCLUSION
Wherefore, for the foregoing reasons, the ISO respectfully requests that the Commission permit it to intervene, and that it be accorded full party status in this proceeding.

		Respectfully submitted,
