Elster Integrated Solutions, LLC (“Elster”) seeks expedited processing of a special
temporary authority to allow small-scale testing of equipment developed under contract
with electrical generation companies. The device to be tested provides a radio
connection between the residential electric meter and the interior thermostat to
reduce electrical consumption during times of peak demand and peak rates. The
equipment has been designed to operate within transmitting power levels acceptable for
Part 15 devices and on a frequency (2.405 – 2.480 GHz) on which the Commission
authorizes Part 15 devices. The transmitting methodology is a standard-design [IEEE
802.15.4, similar to “ZigBee”].Accordingly, no harmful radio interference should result
from the tests proposed herein.

Please note that the emission designator appears to have auto-filled incorrectly in the
STA filing form. The correct Emission Designator is 1M6G2D.

The purpose of the test is to allow the power utility to assess the reactions of
residential customers to the pricing and usage information supplied through the system
and to determine whether the system provides information in a form that will allow the
customer to govern usage during peak hours to reduce the customer’s electrical bill and to
reduce the demand on the electrical system during peak hours. The system also allows the
utility to adjust energy usage in the home through making slight adjustments to the
thermostat settings. The customer has the option to override these adjustments, and the
utility’s monitoring of this behavior is important to the study. Based on information
from this short-term test, Elster will proceed to revise the developmental equipment as
necessary and seek Part 15 certification for the devices.

The equipment will remain the property of Elster until it has proper FCC certification.
For each home in the trial, one transceiver unit will be embedded in the metering
equipment owned by the electrical carrier and will remain outside the control of the
residential user. The other end of the communication link will be another transceiver unit
that is embedded in the home’s thermostat. Some homes have two thermostats, and so
those will have two transceiver units in the home. Elster and the electrical carrier will
track installation and usage of the units for the duration of the test period. Residential
users participating in the test will be customers who have specifically requested to
participate in the test.

Elster requests authority for 500 transceivers for the electric meters and 1000 transceivers
for thermostats, because the power utility and the public utilities commission seek an
appropriately-sized sample to determine the effectiveness of the equipment and the
energy conservation algorithms. This sample size is required by the power utility and is
essential to determine customer acceptance and behavior over a statistically significant
population. The power utility needs to learn how accepting the customers are to
responding to messages from the utility, and complying with thermostat control by the
utility. The utility also needs a large population to measure the impact of their power
reduction actions (e.g., thermostat adjustments) upon the power generation and

an approximation, and will vary depending on the location of the actual residences which
sign up for this experimental program.
