TDSP Advanced Metering System (AMS) – Strategic Objective
4
TDSP Advanced Metering System (AMS) - Requirements
Provide 15-minute VEE (e.g. Validate, Edit, Estimate) data to customers, REPs,
Third- Parties 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.

Over 6.1 million advance meters deployed Over 2 million automated market-driven reads & remote disconnects /
reconnects Over 8 million vehicle miles saved Over 13,000 Home-Area-Network (HAN) devices deployed with SEP 1.0 Over 39,000 residential users registered with the Smart Meter Texas
portal (approx. 250 per week being added) Over 6.1 million meter reads processed daily versus monthly Over 585.6 million 15-minute interval reads processed daily Meter Read Success Rate (98-99.5%) ERCOT 15-minute Settlement

Demand Response (DR) Potential in ERCOT
Source: FERC 2009 National Assessment of DR, page 42
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.”
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 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

Challenges / Lessons Learned
Managing Meter Firmware Managing data volumes / retention / transport Managing solution scale (Network, Communications, Servers etc.) Managing deployment schedules Managing Customer experience and communications 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
19
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

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.
