TDSP Advanced Metering System (AMS) –
Strategic Objective
 Support energy conservation
strategies
 Provide environment for customers
to make informed decisions
 Improve reliability & efficiency of
system
 Create opportunities for customers,
Retail Electric Providers & ThirdParties
2
TDSP Advanced Metering System (AMS) Requirements
 Provide 15-minute VEE (e.g. Validate, Edit,
Estimate) data to customers, REPs, ThirdParties and ERCOT
 Provide 2-way meter transactions (e.g.
disconnects / re-connects, on-demand
reads etc.)
 Provide secured connections and services
to Home-Area-Network (HAN) devices via
ZigBee SEP 1.0 (Up to 5 devices directly
connected to the meter)
 Provide a common Web Portal for REPs,
customers, and customer authorized 3rd
Parties (e.g. GUI and APIs)

Public Utility Commission of Texas (PUCT) Project
#34610 – Implementation Project Related to
Advanced Metering
The purpose of this project is to identify and
implement changes needed in retail and
wholesale markets as a result of advanced
metering. Issues relating to settlement, the
Smart Meter Texas web portal, security, the
Home Area Network (HAN), demand
response, and customer education, among
others, will be studied in this project.

TDSP Advanced Metering System (AMS) –
State of Texas Regulations
Public Utility Regulatory Act – 1999 – Texas Deregulation
Section 39.101
• Prior to Customer Choice in 2002, these key retail customer protections were established that
Entitled a Customer:
• to Privacy of customer consumption and credit information
• to Accuracy of metering and billing
Public Utility Regulatory Act - 2005 – Texas Advanced Metering
Section 39.107
• All Meter Data, including all data generated, provided, or otherwise made available, by
advanced meters and meter information networks, Shall Belong To A Customer, including
data used to calculate charges for service, historical load data, and any other proprietary
customer information.
• A Customer may Authorize Its Data to be provided to one or more retail electric providers
under rules and charges established by the commission.

Customer Enablement –
Oncor Services
Oncor support for Electric Vehicles
 Give-away as part of Biggest
Energy Saver program
Oncor support for HAN devices
 24 devices from 16 manufacturers
have been validated with Zigbee
Smart Energy Profile 1.0
 Two HAN devices were used for a
500 account demonstration
7
Customer Enablement –
Smart Meter Texas portal
The web portal launched March, 2010
provides customers tools to:
 Understand energy usage
 Better manage usage
 Lower electric bills
 Provision HAN devices
 Export functionality for additional
analytics

Demand Response (DR) Potential in ERCOT
FERC estimates >18 GW of DR potential in Texas by 2019
 Attributed to high peak demand
 This would represent 20-25% of total ERCOT peak!

ZigBee Smart Energy Specification
The nature of the Standard Specification:
“All SE messages/directives (Demand Response events, price
publishing, messaging) are assumed to be created by the same
entity, e.g., utility or energy management entity, or set of coordinated
entities.”
Versus
The nature of the Texas Market:
• There are no limits on the number of HAN Service Providers
that could participate in sending HAN messages to customers’
HAN devices
• HAN Service Providers have options of communicating with
customers’ HAN devices either through the SMT / TDSP
systems or through the Internet – controls placed in one
environment will not affect what is done from the other
15
environment
Texas Market HAN Operational Considerations
 Load Control messages submitted by one Service Provider may be
overridden by a second Service Provider
 Load Control message might target an unintended device
 Load Control messages submitted by one Service Provider may
override a Pricing Message of a second Service Provider
 Pricing Message submitted by one Service Provider may override a
Pricing Message of a second Service Provider
 Service Providers will not be able to target specific HAN devices
with Pricing messages
 Service Providers will not be able to target specific HAN devices
with Text messages

 Managing solution as a SCADA system
 Managing convergence of IT and OT
 Managing security and Customer privacy requirements
 Managing employee skills
 Understanding meter functionality
 Understanding how to use the new data
 Understanding how to use the new tools
17
Challenges / Lessons Learned
 Understanding evolving Industry Standards and associated gaps
 Understanding Regulatory requirements and associated gaps
 Understanding new Customer programs
 Understanding new Vendor programs / products
 Managing Change
 Identifying skills for higher order functions
 Identifying a common set of requirements for all parties
 Collaboration
 Establishing a common implementation philosophy
 Using a common set of standards based on different technologies
 Establishing a baseline platform capable of expansion
 Lack of conformance product / end-to-end testing programs
18
Item to Consider
It is no longer just about managing
customers, meters or assets. It is
about establishing new services and
processes across business functions
and markets.
