1 DTE Energy CIM Experience CIM Role in Smart Grid for Transmission and Distribution EPRI Conference, Washington DC 08-Sep-2010

2 Focus of discussion Fast forward -- DTE Energy background Strategy -- key factors, gaining acceptance, and moving forward Implementation -- experiences with project teams 2

3 DTE Energy Overview: Facts and Figures Company Name: DTE Energy Co. (NYSE:DTE) Corporate Headquarters: One Energy Plaza Detroit, Michigan Chief Executive Officer: Employees: 11,000 Anthony F. Earley Jr. Financial Information: Revenue $8 Billion Net Income $530 Million Market Cap $7.4 Billion Assets $24 Billion Avg. Shares Outstanding: 165 million 3

and other renewable energy sources Contributions of nearly $7 million to non-profit organizations

5 DTE Energy Overview: Interesting Facts 10th largest electric utility and the 11th largest gas utility License application filed to commission a new Nuclear plant Investing $1 billion in biomass, solar, wind and other renewable energy sources Contributions of nearly $7 million to non-profit organizations Currently operating in 26 states U.S. Department of Energy grant of $84 million will accelerate our Smart Grid program 5

6 SmartCurrents sm = The Future of Energy SmartCurrents = Data -Connected Model -Equipment Specifications -Continuously updated mapping data SmartCurrents = Customer Satisfaction -Shorter, less frequent outages -Control of home energy consumption and cost -Wind Power, Solar Power, and Electric Vehicles SmartCurrents = Job Satisfaction -Dispatch direct to trouble locations -Reduced patrol time, particularly at night or in bad weather -Better operating maps and mapping products 6

8 Continuous Improvement is one of the top corporate priorities Capabilities of the operationally outstanding Capability 1: Design work to see problems All work is designed so best practices are captured and problems are evident immediately. Capability Capability 2: Swarm 1: Process problems Design when they occur Problems are immediately addressed, both to contain their effects from propagating, and to trigger problem solving. Failure Mode: Pre-specification to Capability ideal 3: (no Share gap knowledge to ideal) where it is created Knowledge generated locally becomes systemic through shared problem solving. Capability 4: Leaders train, coach, assist and teach Leaders have to own the capability development process. 8

10 CMI at DTE Energy: The Perfect Storm

11 Purpose: Describe SmartCurrents IT approach for managing application interfaces 1. The most significant NIST standard for Smart Grid Interoperability relevant to IT applications is IEC 61968/61970 Common Information Model (CIM) and SmartCurrents IT work shall comply 2. SmartCurrents shall develop an Enterprise Semantic Model (ESM) as the basis for all application interfaces 3. SmartCurrents shall have a centralized project team with responsibility to ensure development of ESMcompliant application interfaces 11

12 IT is key for smart grid through end-to-end system integration of utility operations; CIM is focal point of IT application interoperability standard Interoperability implies both inter-utility and intra-utility Most standards relate to devices, interconnection, security, but most important to applications pertain to semantics Semantics: The study of meaning; in IT, the meaning or definition of data 12

13 An ESM is a definition of terms, concepts, and data that is a corporate standard independent of any single department or application Assertions: Also known as a Canonical Data Model; a proven pattern for system integration The lack of an ESM results in a proliferation of application specific data implementations this is the root cause of point-to-point interfaces and accidental architecture The CIM is sufficient to provide a basis for a comprehensive ESM that meets the needs of SmartCurrents and DTE Energy Incremental integration using the ESM to define data messages is a successful approach for ESM refinement and application interface development 13

14 An industry problem is point-to-point interfaces: each interface is a mapping between two application data implementations OMS GIS CIS WMS DMS AMR 14

15 The IEC Interface Reference Model (IRM) Provides The Framework For Identifying Information Exchange Requirements Among Utility Business Functions All IEC Activity Diagrams and Sequence Diagrams are organized by the IRM CIM Users Group: CIM for Enterprise Integration 15

16 The CIM provides the basis for the DTE Energy ESM, then we extend it as necessary to meet situational needs 16

17 Key Concept: Incremental Integration - in Step With Business Needs OMS GIS CIS Semantically Consistent ESB WMS AMR DMS CIM Users Group: CIM for Enterprise Integration 17

The required skills and maturity for ESM/CIMbased implementation requires a centralized approach with our best technical people Provides: Needs for application integration or

Application data semantics Receives: Needs for application integration or interface Service and payload design Technical Architect acts as liaison supporting both ESM Services

18 The required skills and maturity for ESM/CIMbased implementation requires a centralized approach with our best technical people Provides: Needs for application integration or interface Application data semantics Receives: Service and payload design Requires: CIM training Consulting services to assist in mapping application to ESM Provides: Application data semantics Receives: Needs for application integration or interface Service and payload design Technical Architect acts as liaison supporting both ESM Services and Application Teams in realizing objectives Provides: Mapping of application to ESM data ESM changes Standards feedback Implementation specifics (ESB) Receives: Standards details 18

19 Several services now exist in our Service Catalog Service Name Description Producer Team createmeterreadings getmeterreadings disconnectmeter Send a request to get meter reading data Send a request to get readings from a meter Send a request to open the disconnect switch of a meter AMI-MDM AMI-MDM AMI Consumer Team CIS CIS CIS resetdemand Send a request to reset demand registers of a meter AMI CIS pingmeters Send a request to get energization status for a list of meters AMI AMI Operations poweroutagenotification Send a notification of a power outage event from a meter AMI OMS powerrestorationnotification Send a notification of a power restore event from a meter AMI OMS 19

21 Steps that the Enterprise Services Development team followed Jump start session with SISCO guided our first CIM implementations. Business partners, IT leadership, and development teams participated in CIM orientation. Working sessions addressed services/object exchanges. Mapping documents created for services outlining attributes of CIM objects. Corresponding XSDs and WSDLs created. Producer and Consumer application teams built interfaces based on the contract. 21

22 As a result of the process, the Enterprise Services Development team proposed CIM changes Use case: Trouble ticket for reporting power problems. Developed new objects. Other attribute format changes. Left with our consultants to recommend changes with the working groups. 22

23 Retrospective What went well? Availability of industry experts. Support from CIM community. CIMUg engagement. Centralized development team for our Enterprise Semantic Model and services. Well defined and documented objects. 23

24 Retrospective What did we learn? Leadership support: getting right people involved at the right time. CIM orientation provides necessary context. Ambassadorial approach to ensure understanding and engagement. 24

25 Retrospective What should we do differently? Repository of results (document management versus searchable web). Assume responsibility for entire services design earlier (error handling, SLAs, and other details). 25

26 Retrospective What still confuses us? No visibility into CIM working group. Confusion around implied duplication. Example: ping a meter for its energization status. MeterReading or EndDeviceControl/Event? How do we get the right people in the room at the right time? 26
