What is a Smart Grid?

DOE puts it this way:


Goal of the smart grid is to collect and
provide the optimal amount of information
necessary for customers, distributors and
generators to
change their behavior

to:


Reduce system demands and cost


Increase energy efficiency


Optimally allocate and match demand and
resources


Increase reliability of grid

Benefits of Smart Grid


According to DOE


Reduce emissions


Lower costs


Increase reliability


Greater security


Flexibility to accommodate new
technologies

7 Core Functions of a Smart Grid


Enable active participation by informed
customers


Accommodate all generation and storage options


Enable new products, services and markets


Provide power quality for the digital economy


Optimize asset utilization and operate efficiently*


Anticipate / respond to system disturbances*


Operate resiliently against attacks and natural
disasters*

* Near Term

What Does a Smart Grid Really Look
Like?


Common components include:


Two
-
way information flow with the
customer


Automated appliances


Self
-
healing transmission and distribution
system


Intelligence on current system conditions


Access to renewable generation sources

Stimulus Bill
-

What is GTC Doing?


Support/monitor weatherization and
consumer
-
focused activities


Monitor funding opportunities


Current opinion is Stimulus Bill has limited
application


GTC has access to adequate funding


Currently unsure of all grant participation “costs”


Continue to monitor participation with
CRN, Members and GSOC on
demonstration projects

Accessing Renewables Through

Grid Improvements


Recent study projected improvements
needed to bring 20 percent wind energy
to eastern interconnection by 2024


Joint Coordinated System Plan (JCSP)


229,000 MW of new wind


15,000 miles of new lines (345 kV
-
765 kV
AC, 800 kV DC)


$80 billion


Excludes Florida

Who Pays For This?


Estimate does not include cost of
underlying transmission improvements


One estimate is an additional $20
-
$160
billion needed to upgrade underlying grid


Another estimate is $145
-
$285 billion
more


This does not include the generation cost

GTC’s Thoughts on a National Grid


Not opposed to a national grid, but those
that benefit should bear the cost of those
improvements


National grid may make an RTO look
attractive


Federal backstop siting authority okay, as
long it is not mandatory


Will monitor interconnection

wide planning

How Smart is GTC’s Grid?

GTC facilities utilize many “smart” elements:


Substations


Intelligent Electronic Devices


Frame Relay Network


Relay Data Server


Remote Revenue Metering/Meter Management System


Supervisory Control and Data Acquisition (SCADA)


SMP Gateway Data Concentrator


Power Quality Meters/Power Quality Server


Digital Fault Recorder Master Server


Remote Maintenance Server


Time Synchronization


Substation Security


Transmission Lines


Remote Controlled Motor Operated Switches


Fault Indicators

Moving Towards a Smarter Grid


Opportunities in substations


Three
-
phase protective devices (fuse replacement)


Substation load transfer schemes


Control of capacitor banks


Fault analysis


Automated alarm schemes


Automated maintenance management


Power quality analysis


Opportunities on transmission lines

How Do We Get There?


Overall, Georgia lacks a detailed Smart
Grid strategy


Work in progress to form a Georgia
Electric Cooperative Smart Grid Working
Group


Includes GTC, GSOC, interested Members


Following EPRI Smart Grid Road Map
development


Focus on long
-
term strategy
