Overview of Scope for Fall Fall Scope – On Demand Read (Moved out of Summer) – Event Subscriptions and Notifications – Support for Third Parties – Change Requests 3

Approach for Fall Design Process Late July upon request one on one requirements design workshops with REPs to understand individual requirements to ensure that Fall baseline framework for HAN and third parties as well as other functionality will support future needs. August – September AMIT Fall functionality requirements and design sessions. August – September parallel AMIT HAN functionality design discussions as appropriate to support Fall third party and other functions. Late July – September AMIT change request review, design, approval 4

REP WEB REBRANDING 30

REP Web Re-branding Requirements and Options BR #Requirement BR Ability to display usage data in portlets for REPs to develop and use, on their own, with their own logo BR a Ability to display monthly billed KWH usage data in portlets for REPs to develop and use on their own BR b Ability to display the REP logo in the portlet Two methods for interpreting the stated requirements – (Synchronous Web Services) API for small amounts of data – Java Portlet Specification 2.0 (JSR 286) Both are machine-to- machine APIs Both offer different strengths/weaknesses 31

REP Web Re-branding Smart Meter Texas Integration Environment REP Portal API REP uses SMT data to present varied views of customer usage SMT Portal End-Customer API Varied data views 32

SMT is Recommending the API Option (Synchronous Web Services) API for small amounts of data – Pros Leverages the existing ad-hoc usage query and HAN web services security infrastructure REPs do not need to build a portal to use this API REPs have unrestricted ability to innovate around the services they offer to customers – For example. A unified view of interval, daily register and monthly billed usage data or advanced analytics – Cons REPs with existing Portals have to build their own portlets Java Portlet Specification 2.0 (JSR 286) – Pros REPs do not need to build portlets but still must have or implement a portal – Cons REP portals are limited to reporting functionality implemented by SMT REPs customer account information must be in SMT – Requires federated identity management JSR implementation is more complex than web service implementation (SMT assessment) 33

REP Web Re-branding Proposal Re-branding is available to ROR only SMT will provide synchronous versions of existing APIs – Interval Data, Daily Usage, Billed Usage Invocations secured using existing system account & credential exchange – Leverages the R1 HAN and ad-hoc query infrastructure Synchronous limits are strictly enforced – 1 ESI ID/40 days for Intervals – 1 ESI ID/40 days for Daily Registers – 1 ESI ID/24 months for Monthly Billed Usage REP responsibilities – Development of their own portlets – Assuring the user has proper access to the data ROR authorizes user access to the ESIID SMT validates the ROR system account and ROR access to the ESIID Not in scope – Assistance in developing REP software 34

SUPPORT FOR REGULATORY 35

Regulatory Overview Registration – Host will setup the initial Regulatory administrative (first admin) accounts Regulatory Admins & Users will have access to ALL ESI IDs Reporting – Have access to existing portal UI usage reporting Interval usage, daily meter read usage, and billed usage No access to premise and meter detailed data – Batch reporting upon request for PUCT History of SMT Access by person (who, frequency, duration) (BR ) History of 3rd Party Access (who, duration) (BR ) Report output will be delivered encrypted to the PUCT Entity address, regardless of who requests the report (CSV format) Data Extracts by Request – No automatic files for Regulatory Users Not in scope – Ad-hoc undefined reports – HAN functionality 36

Regulatory Registration Regulatory Entity View meter usage data for all Texas Smart meters. Request Access to an Existing Regulatory Accountor see if your Regulatory entity is already registered. Regulatory Entity View meter usage data for all Texas Smart meters. Request Access to an Existing Regulatory Accountor see if your Regulatory entity is already registered. Access will be via Private URL 37

Reporting: History of SMT Access by Person 38

Reporting: History of 3 rd Party Access This report is contingent upon development for the 3 rd Party role. It is being removed from the Summer release and will be bundled with the 3 rd Party functionality in the Fall release. 39

SUPPORT FOR SUPPLEMENTALS (FRIENDS AND FAMILY) 40

Supplemental (Friends) Concepts Master Agreement One Master Agreement defines that there is a relationship between the Customer & the Friend Master Agreement ties to Friends by UserID, once active Pending Friend agreement contains Key + Either party may end the agreement at will ESI ID Agreement Customer may add or remove ESI IDs to the Master Agreement Tied to Master by prefix on Agreement-ID Customer may change permissions at will Friend has view-only to ESI ID Agreement 41

Supplemental (Friends) Overview RES Customer as Supplemental – Only Residential accounts are eligible to be Supplemental Users Non-existent SMT User Registration – Only Residential Customers can invite people to register as a Supplemental – Registration as a Supplemental User (not an existing RES Customer) is by Residential Customer invitation (Agreement Key) – SMT matches on address and Agreement Key 42

Supplemental (Friends) Overview Access to data is authorized by Customers – Only Residential Customers can create Friend Agreements – Customer creates a Master Agreement with the Friend – Customer may have a maximum of 5 Friends – Customer grants access by creating ESI ID Agreements under the Master Agreement – ESI ID Agreements have no expiration date but can be removed at any time – Authorization for ‘data’ includes interval usage (13 months), daily meter reads (13 months), billed usage (24 months), – Access is granted by address and agreement key ( address is not unique in SMT); relationship is with Friend’s UserID once the Friend accepts the Master Agreement 43
