Electric Distribution Quick Facts • We operate 4kV, 12kV, 17kV, 21kV, 34kV, and
44kV distribution systems ‒ System Design
• Radial distribution system • High feeder utilization (71%)
‒ Automation • Currently deploying mobile technology to
field workforce • Increasing SCADA visibility
(today 60%) • Deploying feeder automation
‒ Network Systems • San Francisco: 1,114 units;
10 network groups, 57 circuits • Oakland: 221 units; 2 network groups, 12
circuits ‒ Distribution Control Centers
• Highly decentralized (13 control centers)
• Consolidation effort underway

Electric Transmission Quick Facts We operate 60kV, 70kV, 115kV, 230kV and 500kV Transmission systems • System is designed:
‒ To withstand the loss of a single element (N-1) or multiple elements
‒ To meet North American Electric Reliability Corporation (NERC) reliability standards
‒ To integrate through 4 inter-ties; (1) Pacific Northwest, (2) Southern California Edison, (3) PacifiCorp, and (4) NV Energy in Nevada
• Focus on Automation ‒ Deploying Modular Protection Automation Control
• Increasing SCADA penetration (today 71%) • Grid Control Center consolidation in 2011 • Upgrading transmission supply projects to San Francisco
and northern San Mateo County ‒ Potrero-Embarcadero 230 kV Project submitted to the
Commission for approval ‒ Moraga-Potrero 230 kV Project, working with the
California Independent System Operator (CAISO) on project need and plan of service

Power Generation
As of September 1, 2014, Power Generation (all non-nuclear generation) is now part of Electric Operations.
This provides a review of upcoming work in our Hydro
Projects for 2015. We have ongoing maintenance of our fossil and Photo-voltaic plants which are already under contract.
