Join Michigan Energy Forum in their discussion of Smart Grids. The panel will discuss and answer the following questions. What is the "Smart Grid" and what does it mean for residential and business utility customers over the next 10 years? How might it impact the cost of electricity, and the ability of utilities to keep the lights on during storms? Come and hear about what is happening in Michigan, and how it might provide economic development opportunities here!

1. We transform energy into information to revolutionize the customer experience July 7, 2011

5. Replacing 2.6 million electric meters

6. Modifying 1.3 million natural gas meters with a remote-reading module

7. Full conversion will occur in phases over multiple years dependent on annual capital fund allocations

8. Currently about 400,000 meters and modules have been installed 4

9. What is Smart Circuit? Installation of equipment and communications networks that will allow remote monitoring and controlling of the distribution system Eleven substations, 55 circuits 5

10. Smart Home DOE Pilot Objectives 6

12. DPP: Dynamic Peak Pricing, a pilot residential time of use rate designed to encourage demand response behavior by charging customers a high commodity cost during peak periods in exchange for lower commodity costs the rest of the time.

13. IHD: In-Home Energy Displays communicate real-time price and consumption information to consumers. Real-time, relevant information at a glance provides customers with feedback they can act upon.

14. Pre-Pay: A billing arrangement that allows customers to pre-pay for electric service when they want and in the amounts that they want, essentially providing a “pay as you go” option for customers.

15. Energy Education & Information: Web based analysis and reporting tools; alerts, goal setting and feedback, all of which support near real-time analysis of energy usage, near real-time energy costs and tips on conserving energy and money

16. Smart Appliances: equipped to react to changing price signals:

17. Refrigerators can delay the start of a defrost cycle

18. Electric clothes dryers could enter an ‘economy’ mode and reduce the heat and extend the drying cycle

19. Dishwashers could delay the start of the clean cycle until prices have dropped below a certain level or a certain time of day 7

20. Technology Demonstration Center Create an educational environment through theconstruction of a demonstration center for customers, employees, legislators and shareholders to see the value of technologies DTE Energy will invest in. The demonstration center will incorporate AMI, Smart Appliances, In Home Displays, Programmable Controllable Thermostats, Energy Optimization, and Renewable Energy technologies. 8
