II.	BACKGROUND
On December 27, 1999, Pacific Gas and Electric Company (“PG&E”), tendered for filing with the Commission, a request to change its ISO Grid Management Charge (“GMC”) Pass Through rate from $.7831/MWh to $.8300/MWh.  This filing is made to conform PG&E's ISO GMC Pass Through Tariff to a recent change in the ISO's GMC Tariff.  PG&E requests that its filing be made effective on January 1, 2000.
III.	BASIS FOR MOTION TO INTERVENE
The ISO is a non-profit public benefit corporation organized under the laws of the State of California.  It is 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.  The GMC charge is assessed to PG&E according to the terms of the ISO Tariff.  The ISO therefore has an interest in this proceeding.  Because the ISO is charged with the nondiscriminatory operation of the ISO Controlled Grid, it is also in the public interest that the ISO participate in this proceeding as a party.  Accordingly, the ISO requests that it be permitted to intervene in this proceeding with full rights of a party.

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,
