II.	BACKGROUND
On December 30, 1999, California Power Exchange Corporation (“CalPX”) tendered for filing proposed amendments to its tariff to accommodate the scheduling of Firm Transmission Rights (“FTRs”), and the new scheduling templates adopted by the ISO for scheduling FTRs, Existing Transmission Rights (“ETCs”), and other contract usage rights.

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.  CalPX states that the purpose of the amendments is as described above; that CalPX is a Scheduling Coordinator under the ISO’s Tariff; that the ISO plans to accommodate the scheduling of FTRs in the first quarter of 2000; that the ISO has developed new scheduling templates for FTRs and revised templates for ETCs; and that CalPX proposes to make its corresponding tariff changes effective concurrently with the ISO’s commencement date for scheduling FTRs or such later date as all necessary CalPX software changes are operational.  See CalPX Transmittal Letter at 1-3.  Based on these statements, the ISO believes that it has a unique interest in any Commission proceeding concerning the proposed amendments.  Accordingly, the ISO requests that it be permitted to intervene herein with full rights as 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,
