II. Background

PG&E owns and maintains electric transmission facilities, communication towers, buildings, structures, and other real property for the purpose of providing electric and gas service to customers throughout its Northern and Central California service area. According to PG&E, these facilities and property have sufficient space and strength to accommodate the addition of communication antennas and related equipment.

AT&T Wireless provides wireless communications services throughout Northern and Central California under licenses granted by the Federal Communications Commission (FCC). AT&T Wireless wishes to support and expand its offerings of wireless communications services and therefore seeks to install and operate additional equipment on PG&E's transmission and communication towers, buildings, and other suitable structures. PG&E is amenable to this arrangement as long as use by AT&T Wireless will not impair the provision of utility service or otherwise adversely affect the safety and reliability of PG&E's utility system.
