Smart Meters and Smart Grid

The topics of Smart Meters and the Smart Grid overlap. In fact, Smart Meters are
considered an integral part of the Smart Grid.

Smart Meters

Employing real
time or “near real

sensors, Smart Meters identify electricity
sumption in more detail than conventional meters. In addition to tracking total
consumption, they gather information about


timing of the consumption and the
quality of the power delivered.
Smart Meters may also send notifications about power
including Drop Outs, Brown Outs, and Black Outs. Obviously, a key element of
Smart Meters is their ability to communicate over a network to the Smart Grid, which
uses the

data to help match

power generation and routing to demand

We can combine the Watchm
an, Saturn, or Echo products with sensors that we have
identified for real
time monitoring of utility power quality at water pump locations.
Additionally, we can provide time
use and pump efficiency data. While

we’re not
looking to be certif
ied for pr
oviding “billable’ data,

we believe that we can provide
“Smart Meter compliant” data that can be used by the Smart Grid

Smart Grid

A Smart Grid keeps electricity generation and routing balanced with consumption. A
Smart Grid stays balanced, even performi
ng “self
healing”, by changing generation and
routing based on Smart Meter data, but also by

art Grid compliant end

modify their consumption

as required
. A
smart end
point appliance may detect specific
power quality changes as a precursor
to local grid strain or, alternatively, the grid may
request a reduction in power consumption with a network
based command.

Using the same real
time sensors mentioned above in Smart Meters, we can develop a
feature for the Iris products that detects a prec
ursor to local grid strain. Additionally, we
can receive and react to a grid command. Many water moving pumps can easily be
rescheduled to move water at different times. Even pumps that run nearly all the time
may have the option of reducing power. For

example, a pressurizing pump may be able
to operate at a lower pressure for a period of time as required by the grid.


As 20% for all power is used to deliver water, we should be relevant to the PG&E
and Smart Grid
. Items that we

would like to get from PG&E:

The SmartMeter™ protocol specification

PG&E Smart Grid protocol (if it exists)


Qualifications for rebates if they exist

Grants (or other financial assistance) if it exists
for the development of SmartMeter™
features in Iris products
