The Evolution of Metering
The electric meter is the most improved upon device in the utility
industry and continues to change as new technologies are discovered
Copper plates were
submerged in an
electrolytic solution and
then weighed
Discovery that two out of
phase AC fields can make a
solid armature rotate.

Outage and restoration notification
Each day, roughly 500,000 Americans spend at least
two hours without electricity in their homes and
businesses. Such outages cost our economy at least
$150 billion a year. (via Bob Galvin, galvinpower.org)

Public Concerns
Privacy
•In the information age, utilities will have
an increasing amount of sensitive
information that will need protection
•Each utility continues to take
responsibility to ensure the protection of
its customers’ private information just as it
has in the past
RF Emissions
•Radio Frequency (RF) emissions are
regulated by the Federal Communications
Commission
•Each utility continues to follow the FCC
regulations and other industry standards
to protect its customers and employees
from RF emissions
Privacy
Nothing has changed…except the way the meter is read
•We are still dedicated to protecting customer information
•No customer information is stored at or transmitted from the meter
•Total energy consumption is all that is measured

RF Exposure
•Smart Meters have been tested & certified to FCC rules
•Smart Meter power is < 1 Watt
•Duty Cycle < 10% (typically < 1%)
•900MHz Public Exposure Limit is 610uW/cm2
•10x safety factor for occupational exposure
•An additional 5x safety factor for general public exposure
•So, there is a 50x FCC safety barrier for public exposure
•Peak measured levels at 1 foot are below this limit
•Typical indoor peak exposure < 1uW/cm2

Progression
• Advances in technology have influenced electric metering over the
last century and Smart meters are the result of that continuing
development
• Smart meters allow utilities to provide many benefits to their
customers
• Smart meters are fundamental in the foundation for a smart grid
• Utilities recognize the concerns of their customers and are diligent
in making sure their grid enhancements comply with all
established federal safety regulations and protect customer data
