requires that equipment support Advanced Encryption Standards as defined by the
National Institute of Standards and Technology. As Delmarva Power’s smart grid
is deployed, the security guiding principles will be implemented and applied as
recommended by the manufacturer and industry best practices. For example, PHI
will use firewalls, VLANs (virtual local area networks), encryption, and other
methods as defined in technology standards to defend, deter, detect and
minimize security threats.
This is very unlikely. Each meter is assigned a unique number for each customer
location. Data from your location are matched with the meter number assigned to
that customer location before being sent to our billing system for processing.

Delmarva Power’s Smart Grid provider, Silver Spring Networks, uses 900
megahertz (MHz) and 2.4 gigahertz (GHz) radios in its smart grid hardware

in devices such as baby monitors, cell phones, remote-controlled toys and
RF emissions are compliant with the levels required by strict federal
regulations and permitted by various international recommendations and as such
should not cause any interference with wireless routers or cordless telephones.

Most smart grid devices use radio frequency (RF) fields for only a few minutes
each day to send signals. Rather than provide continuous output, Delmarva
Power's smart meters are idle most of the time, only turning on periodically to
send a brief transmission. An individual meter is idle more than 99 percent of
Over the past decade, there have been hundreds of studies in this area. The
smart meters being installed by Delmarva Power use very low-power radio
frequency (RF) fields to transmit power usage data. The RF fields used by smart
meters are in the same frequency ranges used by cellular and cordless phones,
but are at much lower power and typically occur for less than a total of one
minute per day.
There is a
large body of scientific research on RF fields and health. Federal regulatory
agencies have conducted detailed reviews of this scientific research and have
not found any reliable basis to conclude that there are health risks related to
RF exposures at levels below recognized standards.
Scientific research has been conducted on radio-frequency (RF) fields and
health for several decades. Recent research has focused on RF at cellular phone
frequencies. This body of research has been reviewed by many public health and
regulatory agencies, including the Food and Drug Administration (FDA), the
Federal Communications Commission (FCC), the World Health Organization (WHO)
and the National Cancer Institute (NCI).
None of these
organizations has found that the RF signals from smart meters cause or
contribute to any adverse health effects. For example, a recent review by the
WHO’s International Agency for Research on Cancer (IARC) concluded that while
some studies suggest a possible relationship to cancer based on prolonged use
of cell phones, RF exposures from cell phones cannot be considered an actual
cause of cancer or even a probable cause.
IARC also found
that there was inadequate scientific evidence of any cancer risk due to RF
fields from environmental sources, such as cell phone towers and wireless
networks. WHO has further emphasized that “no adverse health effects have been
established as being caused by mobile phone use.” For detailed information
