Southern California Edison Overview
SCE provides power to:
– Nearly 14 million people
– 180 cities in 50,000 sq-miles
– 11 counties
To deliver that power it takes:
– 16 utility interconnections
– 4,990 transmission and distribution circuits

What is “Grid of the Future?”
A network that uses information technology to deliver electricity efficiently, reliably, and securely.
– Enables bidirectional flows of energy and uses two-way communication and control capabilities
Unlike today's grid, which primarily delivers electricity in a one-way flow from generator to outlet
– It's been called
“SmartGrid”
“Electricity with a brain"
“Energy internet"
“Electronet."

SCE is conducting 2 smart grid demonstration projects funded
by the American Recovery and Reinvestment Act of 2009
(ARRA).
(1) Irvine Smart Grid Demonstration (ISGD) project
Demonstrate new smart grid technologies which can
reduce energy costs and emissions.
(2) The Tehachapi Wind Energy Storage Project (TSP)
Evaluate a utility-scale, lithium-ion battery system to
integration with large-scale, wind-powered electricity
generation.

Summary • SCEnet has been performing well for over 15 years but needs to
evolve to support exponential growth in network traffic and future Smart Grid applications
• SCE’s Unified Communication Architecture anticipates all enterprise needs
• SCEnet2 provides evolution to an efficient and flexible packet-based network to provide a scalable foundation for future communication services.
New technologies and applications require a new approach
Exponential traffic growth demands elastic bandwidth capabilities
Optimized network characteristics meet high performance and low
latency criteria
Flexible network to facilitate end to end Smart Grid connectivity
IP/MPLS/Ethernet over DWDM
LTE & WiMAX • SCE is open-minded and explore new possibilities.
