6. AMS Background “…put information and control
into the hands of the consumer,
Oncor’s AMS initiative has evolved as a with integrated technologies that
enable individuals to obtain timely
result of PUC regulations: information on energy use, manage
their own consumption patterns
and reduce costs.” – PUC
Oncor launches its automated meter reading initiative and begins
2005 replacing traditional meters with automated meters.
The Public Utilities Commission of Texas (PUC) adopts its advanced meter
2007 ruling, including specific technical and functional requirements
for meters.
Oncor’s automated meters are not compliant with the PUC’s new regulations
and as a result, Oncor revises its automated meter reading
initiative to become an advanced metering system that is PUC-compliant.
The PUC approves Oncor’s AMS program filing, including a surcharge to
2008 recover implementation costs.

7. PUC Requirements for Advanced Meters
Provide remotely activated disconnects and reconnects on all
residential meters
Provide 15-minute interval data, which equates to almost 3,000
reads per month per meter versus the historical one read per month
Provide consumption data to HAN and communicate with HAN
devices, such as in-home energy monitors
Give REPs ability to directly interact with the consumer’s meter,
including getting on-demand reads and sending messages and
control signals
Provide market-defined Web portal functionality

9. AMS Benefits
AMS:
 Supports energy conservation strategies with increased system
functionalities
 Provides an environment for consumers to make informed decisions
about their energy consumption
 Improves the overall reliability and efficiency of our system
 Creates new opportunities for consumers and REPs
 Delivers an infrastructure that facilitates the partnership with REPs in
providing customer choice and a high-quality service standard by
which others are measured

10. AMS Features and Benefits
Once fully deployed, AMS offers numerous benefits to consumers,
REPs, and Oncor:
Feature Benefits
Advanced meters  Offers consumers nearly 3,000 meter reads per month rather
automatically read and than one historic read, allowing more timely adjustments to
record meter data at energy use
15-minute intervals.  Increases REP billing options, including time-of-use rates, rates
that foster demand response, and prepaid services, giving
consumers new avenues for controlling their energy costs
 Eliminates the need to send a person to read and record meter
data, reducing vehicle emissions and reducing vehicle accidents
Advanced meter  Eliminates the need to send a person to manually perform
disconnects and service orders, reducing employee safety issues and reducing
reconnects can be vehicle emissions
performed remotely.  Provides the ability to initiate selective load reduction without
impacting sensitive or critical loads, improving response to
emergency curtailment operations
 Enables prepaid retail pricing, allowing consumers and REPs to
have pricing plans that meet their needs

Feature Benefits
Advanced meters  Provides the ability to detect outages faster and pinpoint quickly
provide power loss where on the system the outage has occurred, enabling faster
signals. outage restoration
Advanced meters can be  Provides the ability to read meters on an as-needed basis,
read on-demand. improving efficiencies with move-ins, move-outs, and other
requests that require a meter reading
 Eliminates the need to send a person to read and record meter
data, enabling real-time diagnostic capabilities and reducing
vehicle emissions
Advanced meters  Enhances visibility of energy consumption to consumers via
automatically send meter in-home monitors, allowing more choices about energy use
data to the consumer’s  Provides demand response and load control signals, allowing
HAN. consumers to take advantage of off-peak and time-of-use rates
