about consumers energy
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
the architects nightmare of 2007
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
the architecture and development methodology
The Architecture and development methodology

Q3 2010


Architectural Recommendation


  • 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


  • 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



Meter Deployment

  • Multiple Vendor Selection and Testing
  • 4000 targeted meters deployed on V1 and 2
  • 1500 targeted meters V3 announcement





AMI Systems Enablement and Standards

Meter & Network

Communications Pilot

Demand Response Pilot

Smart Grid Pilot

Load Management

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
strategy for getting key suppliers to use standards
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

  • 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

SEP 2.0


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

conclusions and lessons learned
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
