Negotiations looking toward contractual arrangements for the purchase of entitlement to electric power and transmission capacity in non-Federal facilities were initiated in June 1968. Public and private utilities in the Southwest were invited to par- ticipate, and a steering committee was formed consisting of a iepresentative from each interested utility and the Bureau of Reclamation. The initial non-Federal parties were: San Diego Gas and Electric Company; Southern California Edison Company; Los Angeles Department of Water and Power; Nevada Power Company; Salt River Project Agricultural Improvement and Power District; Arizona Public Service Company; Tucson Gas and Electric Company; El Paso Electric Company; and Public Service Company of New Mexico. While others did attend the June meeting, the above group con- stituted the core of those interested. The steering committee appointed several task forces to study various facets of the overall problem. These task forces covered the problems involved in the construction and operation of the power generation and transmission facilities, including design, costs, legal and tax considerations, coal leases and other property agreements, socio- economic aspects, loads, and resources. In February 1969 the El Paso Electric Company and the Public Service Company of New Mexico decided not to participate in the joint project. This decision necessitated modification of the initially contemplated development. Negotiations continued. In May 1969 the San Diego Gas and Electric Company and the Southern California Edison Company decided that they did not desire to participate in the joint effort, which at that time contemplated two powerplants, one near Page, Arizona (Navajo), and one near Farmington, New Mexico (Four Corners), with six 820-mw units and a total electric power capacity of 4,920 mw. The Southern California Edison Company will, however, be involved as a purchaser of a major portion of United States entitlement to generation and transmission prior to need for Central Arizona Project pumping.
