II.	BACKGROUND

On October 6, 1999, Southern California Edison Company (“SCE”) tendered for filing with the Commission amendments to the existing firm transmission service agreements between SCE and the City of Riverside, California (“Riverside”). These amendments are designed to implement Riverside’s election to convert transmission loss provisions in the existing service agreements to the ISO’s Tariff loss provisions, pursuant to Section 6.4.3 of the Edison-Riverside Restructuring Agreement. 
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 SCE, as well as for the coordination of the competitive electricity market in California.  As the proposed amendments are designed to bring provisions of firm service agreements in line with provisions in the ISO’s Tariff, the ISO 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,
