Consumers Energy’s focus on Using and Enhancing Industry Standards

1. Consumers Energy’s focus on Using and Enhancing Industry Standards

2. About Consumers Energy • Serving Michigan families and businesses since 1886 • We provide electric and natural gas service to 6.5 million people • 8,000 employees • Serving all 68 Lower Peninsula counties

3. The architects nightmare of 2007 • Unprecedented interoperation with other equipment companies, markets • Unprecedented technology expenditure on new technology, new methodology, new benefits • No-one was talking the same language and many people thought they could all talk what they called end to end. • Few had a vision of how big end to end would be • Would a service provider dealing with the premises receive the same data that the utility received after various translations and transformations. • Would the utility and service provider want to exchange the data they both received. Should it be similar? • Need for a thoughtful, tested, well architected, collaboratively created direction and validation of customer benefits

4. The Architecture and development methodology Q3 2010 Final Architectural Recommendation Assessment • SAP, SCADA, OMS, 3 MDUS vendors, 7 network vendors, many smart appliances, many smart devices,many Service providers • Premises effecting tests, outages, disconnects, etc. Mass Deployment Highly Structured Environment: * Full scale production environment * 3.5 million meters Architecture • Design of the network, systems, interfaces, applications, etc. • Work with vendors on system technical requirements and standards Field Pilot • Quasi production environment for controls & processes • Study and operate vendors/technologies as designed by architecture • Rigorous functional testing and operational performance • Up to 4 network vendors • Test business case assumptions

5. Implementation Ramp-up Meter Deployment • Multiple Vendor Selection and Testing • 4000 targeted meters deployed on V1 and 2 • 1500 targeted meters V3 announcement 2009 2010 2011 2012 AMI Systems Enablement and Standards Meter & Network Communications Pilot Demand Response Pilot Smart Grid Pilot Load Management Pilot

6. Goals of the Smart Grid Program • Consumers Energy expects efficiency in: • Energy Delivery • Outage restoration • Customer service • Customer energy usage • Response to price • Business Case life cycle design • Design for layered architecture • Design for upgradable architecture • Design for commonality in phy/mac/network where possible • Design for optimal Common Information Model • Build on IEC internationally accepted standards and work to make them what we need

7. Strategy for getting key suppliers to use standards • Translation and Transformation is at best a necessary evil • Standards need extensions to meet requirements • Users need to get together in task forces to state requirements • Incorporate industry best practices extensions into Standards. • Consumers Philosophy • Work with others and collaborate don’t build a one off • Through users groups speak with a common industry voice • Get many areas moving to the same standard • Validate reality over geek speak • Put your money and your time where your mouth is. • Save money through economy of scale and simplicity of solution

8. Examples of effort • UCAIug Board Of Directors, OpenSG committee member • SG-Systems Co-Chair funding • AMIent Chair and Co-Chair funding • AMInet Chair team member • NEMA task force member, NAESB SG task force co-chair • Zigbee alliance, Homeplug Alliance, IEEE P1901, 2030, etc. • Funding WG14 international convener • SAP lighthouse council • Working with development team on changes for CIM compliance • Working with MDUS vendors towards CIM compliance • Working with OMS, and AMI vendors to become CIM compliant • Testing End to End / Cross domain / In real working environment • Test to scale

11. SG-Systems WG Process Overview- “Consumers Energy Primed the Pump with AMI-Ent Contributions” NIST EPRI, MultiSpeak HomePlug & ZigBee SE 2.0 IEC TC57 WG14, OASIS, IEEE Other SDOs Use Cases From SCE and others Task Forces Business-Oriented, Common Format Use Cases Based on SRS Reference Model Use Case Team System Requirements (SRS) Team Service Definitions Team • Recommendations to IEC TC57 WG14: • Proposed CIM Extensions • Message Schemas Updates • Requirements Updates • Recommendations to other SDOs • Integration Requirements • Patterns • Sequence Diagram • Services • WSDL Interoperability Testing Team

12. Use Case Driven

13. CIM-Based Service Identification

14. Inventory of 142 CIM-Based Services Supporting Use Cases for AMI-Enterprise (Refer to http://www.smartgridipedia.org/index.php/AMI_Enterprise)

15. Supporting the Smart Energy Profile 2.0 Development

16. Following a similar process for the HAN IEC OpenHAN SAE SEP 2.0 MRD Submit use cases, recommended CIM extensions, and recommended XSDs to IEC TC57 Define functional requirements for SEP 2.0 Technical Requirements Document (TRD); Review artifacts through ZigBee and OpenSG meetings Develop SEP Sequence Diagrams Develop SEP schema and service design based upon AMI-ENT architecture patterns and design principles Extend the CIM as required to meet SEP data requirements

18. Conclusions and Lessons learned • Start with the end in mind • One offs are much much easier (and you don’t have to ask anyone) • To many people deploying one offs while hoping to retire early • Pros/cons in working with user groups to drive industry standards • Artificial tests and brochures are no substitute for the real thing • No one is big enough to drive this market • CIM is not complete but is the best thing available • Only through acceptance and openness to industry best practices can CIM advance at the rate that is needed

19. Let’s Git R Done Even while realizing it never will be
