What is Smart Grid/Metering for electric
distribution? Should they be implemented in the
US?

What is Smart Grid?
● Advanced technology aimed at increasing the efficiency of the
country’s aging electricity infrastructure and accommodating
emerging energy sources.
● Makes it easier for electricity distributors to gather and act on
information, such as information about the behaviors of suppliers
and consumers.

●
A smarter grid applies the three T’s to bring knowledge to power…
o Technologies
o Tools
o Techniques
●
They apply knowledge capable of making the grid work far more
efficiently by…
o Ensuring its reliability to degrees never before possible
o Maintaining its affordability
o Reinforcing our global competitiveness
o Fully accommodating our renewable and traditional energy sources
o Potentially reducing our carbon footprint

● Transforming our nation's grid has been compared in significance
with building the interstate highway, or the development of the
internet.
● These efforts, which are rightly regarded as revolutionary, were
preceded by countless evolutionary steps. Much like a highway is
built or how the internet came to be today, the Smart Grid will
evolve over time.

●Power System Fact
o Today’s electricity os 99.97% reliable, yet still allows for
power outages and interruptions that cost Americans at least
$150 billion each year. Which is about $500 for every man,
woman, and child.
Viewpoint #1: Benefits for implementing Smart Grid in the US
● More efficient transmission of electricity
● Quicker restoration of electricity after power disturbances
● Reduced operations and management costs for utilities, and
ultimately lower power costs for consumers
● Reduced peak demand, which will also help lower electricity rates
● Increased integration of large-scale renewable energy systems
● Better integration of customer-owner power generation systems,
including renewable energy systems
● Improved security
Smart Grid technologies in other countries
● China’s smart grid is about
10,000 meters now but by 2020
they plan for it to about 300 million
meters.
● If the test phase is successful,
SGCC (Smart Grid Corporation of
China) will cover about 80% of the
country.
Self-Healing Grid
● A self-healing grid includes these primary functions:
o Real-time monitoring and reaction, which allows the
system to constantly tune itself to an optimal state
o Anticipation, which enables the system to automatically
look for problems that could trigger larger disturbances
o Rapid isolation, which allows the system to isolate parts of
the network that experience failure from the rest of the
system to avoid the spread of disruption and enables a more
rapid restoration.
Consumer benefits of Self-Healing Smart Grid
●
●
Beyond, managing power disturbances, a smart grid system has the
ability to measure how and when consumers use the most power. This
information allows utility providers to charge consumers variable rates
for energy based upon supply and demand.
Ultimately, this variable rate will incentivize consumers to shift their
heavy use of electricity to times of the day when demand is low and will
contribute to a healthier environment by helping consumers better
manage and more efficiently use energy.
ViewPoint #2: Drawbacks of Implementing the Smart Grid in the US
Security
• Cyber-security threats
• Theft
• Power loss
• Computer malware
Cont.
Costs
•There is a huge initial investment cost for the utility company
•Energy prices rise for consumers (variable pricing)
•Heavy government support through grants and stimulus packages
Still Cont.
Cultural Lag
•Consumer adoption to these smart grid technologies takes years
•Will consumers truly use this data in their homes and take advantage of it?
•Consumers may not benefit as much as the utility companies who are pushing smart
technologies
Conclusion
• While both the benefits and drawbacks are
significant, both sides seem to balance out
the other …
• For example: Security problems might rise
from this smart technology, Smart grids
when used and implemented PROPERLY
can save everyone time, money, and at the
same time benefit the environment.
Conclusion Cont.
• Another stalemate between positive and
negative is that despite the threat of possible
cyber attacks a self healing grid can attempt
to anticipate things going wrong, isolate the
problem, and solve it before it gets out of
hand.
Cont.
• So all in all, in the end with kinks ironed out,
the smart grid could be a viable solution for
issues related to both consumers and
producers.
