3 Can We Change the Way We do Business? Utility service has essentially been measured and billed the same way since we started doing business over 100 years ago. Customers receive information once a month after they use the service. Smart Meters -> > Smart Utility ->Smart Customers 3

4 What is the Smart Grid? A smart grid delivers electricity from suppliers to consumers using digital technology to save energy, reduce cost and increase reliability and transparency. Essential Components 1. AMI Network Meter-to-meter true two-way network that can provide near real-time data to the utility and our customers and enable remote disconnect and load control. 2. Meter Data Management System System that can store, test, analyze and process large volumes of utility records produced by the AMI network, and share data with the CIS, OMS and other utility applications. 3. Web Application A robust customer interface that can provide easy online access to account information, allow for account management, on-line energy audits, and facilitate demand response participation. 4. Customer Tools devices such as programable controllable thermostats, smart appliances, in home displays, and other devices that provide intelligent control of a customer s energy usage.

10 Phase III - Pricing Programs Pricing options will focus on customer choice and be designed to encourage conservation and better reflect the cost at the time electricity is produced. Options such as nights and weekends, family plan, college plan, prepaid etc % more efficient Unit Heat Rate Critical Peak Pricing Hopkins 2 Purdom 8 Hopkins 3 & 4 Hopkins 1 Purdom 7 0 MWh/MMBtu Smart Meters -> > Smart Utility ->Smart Customers 10

11 Phase III - Customer Tools Devices like smart thermostats will provide the flexibility to share month-to-date consumption and cost information with customers, and provide the ability to initiate temperature set-back or load control based on the customer s choice. These thermostats and other similar devices may be available off-the-shelf as programs in the industry become more prevalent. Smart Meters -> > Smart Utility ->Smart Customers 11

12 How Do Customer Devices Work with the Smart Grid? ZigBee Smart Energy Profile has emerged as the accepted standard for Smart Grid HAN communication. Designed for cost effective low powered communication standard for battery powered devices. Based on IEEE standard Must be a member of the ZigBee Alliance to include the protocol in product.

13 Lessons Learned Our Vision has stayed consistent and has strengthened through the process Good buy-in from leadership and business community Manage staff reduction promises carefully. Make sure all involved understand each other's organization; Muni vs. IOU, etc. (Who has your vendor worked with before.) Monitor national stories Public Opinion is evolving.

14 Lessons Learned More work on front end with all Departments Be more realistic about our Transition window, may actually require more work from staff. At times you will know more than your vendors Vendor coordination AMI & MDMS Stronger focus on vendor training plans You will be unpopular at the beginning, much more popular as project approaches close-out.

15 Lessons Learned Don't pay meter installers by the piece. Encourages harvesting of low hanging fruit, leaving utility with the tough stuff. Trust your contractor to do a good job BUT VERIFY. Install data collecting network first. Get involved with the coverage plan. Pilot every change before implementation. It will take longer than planned. Murphy is on the job.
