1. SCE Service Territory
SCE
• One of the nation’s largest electric utilities• Serving a population of nearly 14 million people• 50,000 in square-mile service area within
Central/Coastal/Southern California• SCE Telecommunication Network - 75,000 miles

Current SCEnet Status
SCEnet, built in the 90’s for $110 million dollars, Has resulted in over a 300% ROI in avoided costs &
revenue generation– Fiber optic: 3,100 route-miles. – Microwave network: 3,792 path-miles. – A private satellite network to provide network connectivity
to over 300 remote substations– 2,568 Hand-held Radios (A private Mobile Radio Network
that is used for emergency communication) – 28,275 Netcom Radios (remotely control devices in the
electric system, and Load Management radio system for Demand Response.)

SCEnet – A Reliable Electric Grids SCE’s fiber optic, microwave, and Netcom network
have helped create one of the most automated, and reliable electric grids in the nation.
Automated portions of the electric system include: – 56% of SCE’s 900 substations, – 41% of the 4,400 electric circuits– 100% of commercial and industrial customers (with
Smart metering).– The Network is supporting the real time monitoring of
over 200,000 points in the electric grid every four seconds.

Requirement Changes for SCEnet2Category Today Future
Facilities with high-speed connections
Top 150 SCE connected locations
Expand to 1,000+ locations
Intelligent Electronic Devices
Millions Tens of millions, includes Smart Meters and intelligent electronic devices
Push-to-talk voice dispatch for construction field forces
Proprietary analog, followed by Open standard, encrypted, interoperable, digital land mobile radio Land Mobile Radio
Anytime/anywhere connectivity
Broadband wireless connectivity to field
personnel and equipment
Mobile data, smart phone Anytime/anywhere connectivity
Security Compliance Current requirements are limited in scope but are expected to be broader and more stringent over time
Strict NERC/CIP, Smart Grid security requirements moving to “military grub” over time
Multimedia and Collaboration
Limited Streaming video, Rich MediaReal-time collaboration
Grid Load via grid management applications
Time-Division Multiplex SCADA IP-enabled Smart Grid control

4.1 Latency:– Telco circuits were not able to meet the very low latency
requirements of important Utility applications. E.g. Phase Comparison Circuits.
– Utilities had to build their own networks to ensure they can support the stringent latency specifications of 2 to 8 milliseconds (i.e. less than ½ cycle).

4.2 Coverage:• Utility crews operate in wide geographical areas many of which are in remote areas
far from populations centers.
• Utility assets such as reclosers, capacitor banks, & regulators are typically distributed in remote areas.
• The Telco business model of providing service only to highly populated areas left huge coverage gaps in the Utilities’ service territory.
• These coverage gaps often presented safety or operational risks that the utility was not willing to assume.

In 2002, Johnstone Peak lost power for several weeks, due to fire, but SCE’s mobile radio serving the area continued to operate using back-up power from engine generators.
4.3 Reliability:• Telco networks built for the mass consumer market often lack the
reliability needed for core Utility applications…voice dispatch or SCADA.
• E.g., whereas Utility base station sites have several weeks of emergency power backup, Telco cell sites have only hours (or days at most) of power backup.

4.4 Emergency Availability: • Telco consumer services run into congestion problems during
emergencies.
• E.G. September 11, the 2005 Hurricane Katrina, the 2009 Hurricane Ike, & the 2007 bridge collapse in Minneapolis.

Lease vs. Own?
SCE has always used a hybrid approach
SCE has relied primarily on its own network for those Utility applications that have demanding latency, coverage, reliability, and emergency-availability requirements.
The question is: moving forward, can SCE rely primarily on the Telcos to support these critical applications, or should it build its own network by refreshing and expanding SCEnet?

SCE still needs to evaluate the leased option for various Smart Grid applications
Business models change over time, so do technologies. We should be open-minded and explore new possibilities.
The Teclos understand “Smart Grid” is the next big area of opportunity, so they are gearing up to see how they can support the Smart Grid rollout. Some are creating new business units just focused on the Energy Sector.
Some emerging 4G wireless technologies may be able to meet some Utility requirements.

6. Conclusions
SCEnet has been performing well for over 15 years SCE’s Unified Communication Architecture anticipates
all enterprise needs SCE Integrated Critical Communications Infrastructure
– A Layered Architecture Vision Utilities had to build their own Integrated Critical Comm
Infrastructure for Critical Applications SCE is open-minded and explore new wireless
possibilities.– Identify frequency bands between 700 MHz and 2.6 GHz
that may be suitable for a private wireless communications in the SCE service territory
– Utilize emerging 4G wireless technologies
