How Do We Serve The Power Industry
"I think there is a world market for maybe five computers."
--Thomas Watson, chairman of IBM, 1943
"Computers in the future may weigh no more than 1.5 tons."
--Popular Mechanics, forecasting the relentless march of
science, 1949
"But what ... is it good for?"
--Engineer at the Advanced Computing Systems Division of
IBM, 1968, commenting on the microchip.
"Who in their right mind would ever need more than 640k of ram!?"

It is not just smart meters
It is not just green energy
It is not just time-of-use rate structure
It is not just HVAC shedding in the summer
It is not just distribution automation systems
What is a Smart Grid
What Smart Grid is!
–
A smart grid applies technologies, tools and techniques
available now to bring knowledge to power – knowledge
capable of making the grid work far more efficiently, reliably...
–
Ensuring its reliability to degrees never before possible
Maintaining its affordability
Reinforcing our global competitiveness
Fully accommodating renewable and traditional energy sources
Potentially reducing our carbon footprint
Introducing advancements and efficiencies yet to be envisioned

What is a Smart Grid
According to William Parks from the DOE, a Smart Grid would:
•Accommodate all types of central and distributed electric generation and storage.
•Provide for power quality for a range of needs by all types of consumers.
•Optimize asset utilization and operating efficiency of the electric power system.
•Anticipate and respond to system disturbances.
•Operate resiliently to attacks and natural disasters
•Enable informed participation by consumers in retail and wholesale
electricity markets.
•Enable new products, services, and markets.

Distribution Driving Factors
13
Lack of Monitoring
Power Companies do not find
out a local branch is down until
someone complains
The local distribution network
covers a very large geographical area

Consumer Driving Factors
Power Company Viewpoint:
Lack of Monitoring
Desire to find ways to encourage consumers to shift loads to offpeak
Consumer Viewpoint:
14
Power Companies do not find out a customer is down until
someone complains
Unable to detect quality issues until something is damaged
Want to manage cost
Make changes remotely

What are Power Utilities Looking
for in a Data Network?
Security
–
Ubiquitous Coverage
–
27
An outage may cause significant equipment damage and may be a
hazard to life
Low Cost
–
The Utility typically covers a much larger service area than the
communications providers
Reliability
–
The system must not be capable of being hacked
The system needs to cost less than their designated recovery
threshold
Very Low Bit Rates
–
100s of bps but from lots of devices
What are their Options?
Broadband over Power Lines (BPL)
–
Cellular Wireless
–
Only works in urban areas, used in conjunction with BPL
Data Network Provider
–
28
Near universal availability, relatively expensive per node,
WiFi
–
Troublesome, low throughput, transformers, someone will figure it
out
Power Utilities are just now starting to investigate this option
Telecom Infrastructure
29
Rapid growth in consumer bandwidth requirements
Rapid replacement/upgrade of telecom infrastructure
Higher bandwidth requirements are driving increased use of
fiber
With fiber, future bandwidth increase requires only new
electronics
Fiber as medium for many purposes – voice, data, video, etc.
Nearly all facilities with an electric meter, also contain telecom
infrastructure
Where Are We Now?
30
Technology exists in Telecommunications to service most all
diversities of Smart Grid platforms. (Bandwidth requirements)
–
However – At what cost?
–
Can a Normal Business Model sustain the needed infrastructure?
–
Are “Our” customers on board?
Where Are We Now?
31
On the Power side of Smart Grid advancement. Extensive
advancement in Electronically Mapped Distribution
technologies and numerous Automatic Meter Reading installs
have set the stage for upcoming Smart Grid projects.
–
However, at what cost?
–
Back to the Business Model----Sorry.
–
What about Distributed Generation, Wind Power etc…
–
How would a Federally Mandated RPS help promote Smart Grid?

32
Circuits
Special equipment – Added expense
Regulated – NECA Tariffed rates
–
– Special
High Cost
Few circuits were deployed – Staff had little
experience with the equipment
Long copper loops – Difficult to troubleshoot
When they worked, they were very stable
How Do We Serve the Power Industry
Data Circuits Today – Broadband The Primary Circuit
of Today
–
Data is what we do – Voice is the declining market
90% of recent investment revolves around data
8kFt DSL Loops
– Wireless
– FTTH
–
33
Redundancy is now standard in IP network designs – five 9s (351.36
seconds of outage per year)
How Do We Serve the Power Industry
Data Circuits Today – Broadband The Primary
Circuit of Today
–
Data is what we do – Voice is the declining market
IPTV has been the driving factor in data network improvements
Video is watched closely
– Disturbances to video circuits very noticeable
–
Staffing has been concentrated around IP experience/training
–
–
34
Traditional CO staff is extensively IP focused
IP experience is provided all the way to the house
How Do We Serve the Power Industry
DSL Circuits
–
Advantages:
–
Disadvantages:
35
Relatively Low Cost – Works on existing copper
Mature Technology – Know how to make it work
Long reach at low bandwidth – 50kbps at 18kft
Point-to-Point
Data rates hindered by noise, especially at longer distances
Less reliable than fiber services
How Do We Serve the Power Industry
FTTH Circuits
–
Advantages:
–
Disadvantages:
36
Mature Technology – Know how to make it work
Long reach at any bandwidth – 100Mbps at 40km
Point-to-Point is very secure
GPON is also secure
Very high service reliability
Very High Cost – Typically requires all new facilities
How Do We Serve the Power Industry
VoIP, Data to
remote
customers

How Do We Serve the Power Industry
Wireless Circuits
–
Advantages:
–
Disadvantages:
38
Fast to deploy
Long reach at low bandwidth
Can be low cost if the infrastructure is in place
Limited range depending on frequency, Line-of-Sight
Growth of wireless data networks has pushed up costs
Reliability can be a factor
How Do We Serve the Power Industry
Conclusions

39
Communication Company Broadband Advantages:
Gain access to a trained work force that already works in the
home
The network may already exist all the way to the home
Can be low cost if the infrastructure is in place
Communication Company Broadband Disadvantages:
100% broadband coverage does not exist today
Return on Investment for Communications Company may be
limited
The need for the Power Utility to deal with a third party
How Do We Serve the Power Industry
Conclusions
–
Pick the low hanging fruit first
Look to serve the Substations
There are not very many Substations
– Many local Power Utilities are not ready to collect very much information from
the consumer yet
–
Look to serve the larger Commercial Clients
Most likely, you are already there
– They can actually affect the Utility’s usage and save money
–
–
40
Form partnerships to create a group that can cover substantial
portions of the Power Utility’s service area
We need Partnership Now
41
Our paths have now converged – Power—Telecom
–
Not just servicing each other as in the past.
–
While Technologies have, and continue to advance – Has
the Level of Cooperation to package our capabilities moved
at the same pace?
Thank You!!
