What is a Smart Grid
What Smart Grid is not!
– – – – – 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
6
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
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 Old Equipment http://craigsland.com/Plot.aspx?plotID=32
Consumer Driving Factors
14
Power Company Viewpoint: Lack of Monitoring Power Companies do not find out a customer is down until someone complains Unable to detect quality issues until something is damaged Desire to find ways to encourage consumers to shift loads to off peak Consumer Viewpoint: Want to manage cost Make changes remotely

What are Power Utilities Looking for in a Data Network?
27
Security – The system must not be capable of being hacked Ubiquitous Coverage – The Utility typically covers a much larger service area than the communications providers Reliability – An outage may cause significant equipment damage and may be a hazard to life Low Cost – The system needs to cost less than their designated recovery threshold Very Low Bit Rates – 100s of bps but from lots of devices
28
What are their Options?
Broadband over Power Lines (BPL) – Troublesome, low throughput, transformers, someone will figure it out Cellular Wireless – Near universal availability, relatively expensive per node, WiFi – Only works in urban areas, used in conjunction with BPL Data Network Provider – 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
How Do We Serve the Power Industry
Data Circuits of Old –
Special Circuits
– – Special equipment – Added expense Regulated – NECA Tariffed rates 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
33
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 Redundancy is now standard in IP network designs – five 9s (351.36 seconds of outage per year)
34
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 – Traditional CO staff is extensively IP focused – IP experience is provided all the way to the house
35
How Do We Serve the Power Industry
DSL Circuits – – Advantages: 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 Disadvantages: Data rates hindered by noise, especially at longer distances Less reliable than fiber services
36
How Do We Serve the Power Industry
FTTH Circuits – – Advantages: 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 Disadvantages: Very High Cost – Typically requires all new facilities
How Do We Serve the Power Industry
37
• Wireless Networks – Bandwidth
dependant on range
– Transmitter
nodes are typically fiber fed
Central Office
Bidirectional Optical Node
VoIP, Data to remote customers
700 MHz, Cellular, WiFi, etc.Transmitter
38
How Do We Serve the Power Industry
Wireless Circuits – – Advantages: Fast to deploy Long reach at low bandwidth Can be low cost if the infrastructure is in place Disadvantages: 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
39
Conclusions – – 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
40
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 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?
