We are committed to the safety, privacy and security of all of
our customers. We believe that our grid modernization efforts, including smart
grid and smart metering technologies, help us achieve these goals.
We also understand that you may
have some questions or concerns around these technologies. Below you’ll find
more detailed information around some commonly asked questions. If you have any
additional questions or concerns, please contact us at 1-855-NEW-METER.
We place the utmost
importance on the security and protection of all aspects of our electric system
and associated sub-systems. In keeping with corporate policy, PHI smart grid systems and
components will guard against cyber and physical attacks.
We require that
equipment support Advanced Encryption Standards as defined by the National
Institute of Standards and Technology. As our smart grid is
deployed, the 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
This is very unlikely. Each meter
is assigned a unique number for each customer location. Data from your location
is matched with the meter number assigned to that customer location before
being sent to our billing system for processing.
We are committed to
ensuring the privacy of your energy use data. Therefore, only the account
holder has access to the data. This information cannot be shared with a third
party, including your landlord, without the written consent of the account
We will retain this
information for seven years.
Our smart grid
provider, Silver Spring Networks, uses 900 megahertz (MHz) and 2.4 gigahertz
(GHz) radios in its smart grid hardware devices – the same FCC-approved
frequencies that have been used for many years in devices such as baby
monitors, cell phones, remote-controlled toys and medical monitors.
Silver Spring 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, or compromise the security of, wireless routers or cordless
telephones. For more information, please refer to our RF Fact Sheet.
Most smart grid devices use radio
frequency (RF) fields for only a few minutes each day to send signals, which
means that 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 the time.
Over the past decade, there have
been hundreds of studies in this area. The smart meters being installed by
us 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
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 provided by these
