2. Aug 20072 Introduction  Purpose:  Information sharing (level setting)  Validate approach  Drive technology implementations  Establish participation and responsibility  Describes utility’s view of HAN  Establishes participation scope and scale  Intended audience:  Regulators – establish position, clarify roles and responsibility  OpenHAN – creates input for further system refinement (e.g., platform independent requirements, use cases)  Vendors – shows approach, motivation  Establishes a baseline  Time management: cuts down on vendor clarification meetings and phone calls  Outline:  Introduction  Documentation process  Guiding principles  Use Cases  System Criteria  Next Steps (Requirements Composition)

3. Aug 20073 Utility HAN Framework  Based on Strategic Planning and System Engineering  Each level provides direction and context for lower level  Delineates participation and accountability  Can be mapped to GridWise Architecture Framework (Loosely coupled - Decomposition framework vs. organizational interoperability view)  Stakeholder considerations at every level: regulators, consumers, utilities, vendors

6. Aug 20076 HAN Guiding Principles Capabilities  Supports a secure two way communication with the meter  Supports load control integration  Provides direct access to usage data  Provides a growth platform for future products which leverage HAN and meter data  Supports three types of communications: public price signaling, consumer specific signaling and control signaling  Supports distributed generation and sub-metering Assumptions  Consumer owns the HAN  Meter to HAN interface is based on open standards  Implementation is appropriate given the value and the cost  Technology obsolescence does not materially impact the overall value

8. Aug 20078 Use Case Scope  Abstracted to highest level for rapid adoption (i.e., more details to follow) note: previous work has been more detailed  Concentrates on Utility to HAN interactions  Device ownership independent (e.g., registration is the same whether or not the utility supplies the device)  Interactions are based on Utility relevant activities only (Ignores other HAN activities within the premise – e.g., Home Automation)  Required device functionality will be specified in subsequent phases (i.e., platform independent requirements)

9. Aug 20079 Organization  System Management and Configuration  Depot Configuration  Installation and Provisioning  Utility Registration  Remote Diagnostics  Maintenance and Troubleshooting  Load Control and Energy Management  Voluntary  Mandatory  Opt-out  Energy Management System  Energy Storage and Distribution  User Information  Submetering

10. Aug 200710 System Management and Configuration  Five scenarios  Depot Configurations – covers any manufacturer certification or configuration steps needed for compliance/compatibility  Installation and Provisioning - covers the activities associated with physical installation and the admission to the local HAN  Registration - covers the steps necessary admit a device to the Utility AMI network as well as any high level consumer/device/application enrollments  HAN Remote Diagnostics – covers the high level activities associated with utility diagnostics  HAN Device Diagnostics – covers on-site troubleshooting steps  Major assumptions and notes  Network provisioning and registration have differing purposes and steps (e.g., network vs. utility admission, security and directional authentication)  Consumer consumption signaling requires registration (confidentiality and privacy)  Utility control signaling requires registration  Public Pricing does not require registration (i.e., needs one directional trust – network commissioning)  Registration requirements could impact manufacturing/depot configurations (implies certification process)  Mobility requirements are supported but not defined within these use cases (e.g., EV/PHEV premise/account/device bindings)

11. Aug 200711 Load and Energy Management  Three Scenarios  Voluntary - covers load reduction at the customer’s site by communicating instantaneous kWh pricing and voluntary load reduction program events to the customer  Mandatory – covers load and energy management scenario refers to demand response resources dispatched for reliability purposes  Opt-out – covers request to opt-our of the program due to a medical emergency/conditions  Assumptions and Notes  The HAN device is capable of differentiating between emergency/reliability and/or price-response event signals.  Certain HAN devices can distinguish or support various event types and take appropriate action based on the event.  HAN Devices do not need to register with the Utility AMI system to obtain Utility messaging (e.g. pricing events). However, the customer must enroll in a demand response program or tariff and must register the HAN device with the Utility for the HAN device to confirm its successful actuation of the event.  HAN Devices receive optional warning messages  Mandatory events require gateway acknowledgement

12. Aug 200712 Energy Management System  Covers the utility to EMS interactions  Assumptions and Notes  The EMS is aware of or can retrieve the types of HAN device types and the status of those devices connected to the HAN and upon registration or change-out. (e.g., fridge on/off)  EMS controls production, consumption and storage within the HAN. (e.g. Controls charging/discharging of an Electric Vehicle)  The EMS can be pre-programmed to respond to utility signals and commands. (e.g., reliability event)  Use case does not imply the utility’s preferred configuration or communication for reliability programs. (e.g., utility may still require HAN device registration)

13. Aug 200713 Energy Storage and Distribution  Covers the connection interaction of the premise Home Area Network (HAN), the Utility AMI system and the electric system (home, vendor or utility’s).  Assumptions and Notes  Dependent on Submetering use case  Energy Supplying Unit (ESU) can be an energy storage device (e.g., electric vehicle battery) or an energy generation device (e.g., photovoltaic array or backup generator).  Assumes that the Energy Supplying Unit (ESU) already contains energy

14. Aug 200714 User Information  Covers utility initiated messages and electric usage updates via an In Home Display (IHD) – does not cover other internal HAN display functions  Assumptions and Notes  Rapid updates to any IHD does not restrict AMI or other utility functionalities  The IHD is either pre-programmed to respond appropriately to price, consumption, load or event messages and/or the customer has manually programmed the IHD  The IHD indicates the status of the communication link with the Utility AMI gateway

15. Aug 200715 Submetering  Covers the measurement of other metering devices within the HAN  Assumptions and Notes:  The AMI system supports Sub meter device-specific, consumer- specific and location-specific rates/billing. (e.g., Electric Vehicle (EV), Plug in hybrid electric vehicle (PHEV)).  AMI system provides pricing information to the sub metering devices.  This use case also applies to other HAN devices with metering capabilities (e.g., other entity gas and/or water meters, EV sub- metering, PV sub-metering, etc.)  This use case assumes multi-lateral information sharing among utility distribution companies (e.g., supports mobility).  Device provides the customer (end user) with the appropriate information. (e.g. % of charge, current rate of consumption, etc)  The device provides the utility AMI gateway with the current energy requirement and task time to completion
