4. Carrier Challenges
Material Condition
The hidden costs of maintaining obsolete equipment. One Trouble Ticket:
Utility
3rd Party Carrier
Obsolete Equipment
Dispatcher receives Audiotone Alarm 1 2
Dispatcher generates ticket and notifies Relay Engineers 3
Relay Engineers dispatch techs and AO to isolate trips and channel.
Maintaining 1960’s technology 4
Tech isolates trips at both stations
Access Concerns 5
Telecom Carrier schedules to meet onsite
2 Area Operators (AO) meet carrier techs on-site at both locations
(“baby-sitting”) 6 7
Technicians make repairs and notify Utility Dispatcher 8
Dispatcher schedules tech’s to validate carrier levels 9
2 Tech’s validate levels at both ends of line and restore trips.
Telephone Company drove into cable trough at a transmission substation 10
Dispatcher schedules AO to return channels to normal
Prior to starting program at ComEd we experienced ~250 trouble tickets per year! 11
AO’s drive to both stations and return equipment to service.

5. Need for a holistic solution
Why Change?
Rising Costs
Reliability
30% Annual increase in DS0 circuits
22% Annual increase in T1 circuits
Electric rates relatively flat
Carrier Technology Sunset
Decline in Analog Skillsets
Disparate backhauls (several CO’s)
Emergent Response (Monday-Friday)
Typical voice POTS line in Chicago now costs ComEd $54.25 monthly compared to $24.05 monthly in 2011 (125% increase in five years).
Our Utility Model is evolving and our network has to ADAPT with it

6. Leased Line Optimization - Digital Grid Strategy
Perform a Exelon-wide assessment of ALL leased circuits (wired). Provide Consistent Management of the program
Expand internal communication network (fiber where we can, wireless where we have to). Standardized Approach
Align communication expansion with all major programs
Security Expansions: Physical Security/Video Surveillance/NERC-CIP
Gas Gates: New SCADA Needs
Substation Expansions: SCADA, Teleprotection, equipment monitoring
Headquarter needs: Office 360, Skype Video, Cloud Computing
Future Utility applications: DER Integration, MicroGrids, Electric Vehicles
Build for the ultimate
Minimize the use of leased services where possible.

7. Stakeholder Relationship with the Business
Our reliance on communications is growing day by day. It’s the backbone to our modern grid and a key enabler to connecting with our customer. The future will require higher bandwidth and more reliable communication networks. 3rd party suppliers charge by the bit and costs will increase.
Monitoring your own performance as if you’re a Carrier
Network Utilization (% Used)
Automate monitoring and alarming
Establish Performance Metrics
Trend Network Performance
Deliver Network SLA’s to the Business
Address performance outliers

8. In Closing…
Carriers have announced movement away from legacy offerings (DS0, T1, etc)
Carrier costs are increasing and they charge by the bit.
Deploying communication systems (fiber, wi-max, microwave, LTE, etc) takes time (fiber deployments, permitting, etc). Teleprotection circuit replacements need to be coordinated with outage windows. Plan on a multi-year program
Align program with ALL of your communication needs and strategically build for your ultimate needs. Consider Security, BackOffice, Protection & Control, SCADA, Distribution Automation, DER Integration, Voice along with other current and future applications.
Reliance on communication systems will only increase as utility applications evolve.
Monitor performance, close gaps, and build your network!
