2 Outline Who is Entergy? Why AMI? AMI Pilot Development & Process AMI Technology Selection Network Overview Demand Response Q&A 2

3 Entergy Footprint 2.7 million customers 2.5 million electric 200,000 gas Four state coverage: Arkansas Louisiana Mississippi Texas 3

4 Entergy Footprint Operating system 15,500 miles of high voltage transmission 1,550 transmission substations Annual revenue exceeds $11 Billion 14,300 employees We are both an urban AND rural utility 4

5 Why AMI? 5

6 Industry issues Energy price increases, price volatility Supply disruptions Increased demand Transmission, distribution, and generation resources dated Peak demand control Environmental issues Corporate citizenship Continuous customer service evolution Labor pressures 6

7 Increasing electricity demand 6,000 Billion kilowatthours 5,000 4,000 3,000 2,000 1, Historical Projected 2030 Sources: U.S. Department of Energy, Energy Information Administration, Annual Energy Review 2005 and Annual Energy Outlook 2007 Early Release 7

8 Electric companies must demonstrate a controlled use of resources to all stakeholders Entergy s footprint has a much larger natural gas component 8

The Value Proposition of AMI Entergy s external customers and constituents Corporate Citizenship The next power plant Customer Service and power reliability Entergy s

9 The Value Proposition of AMI Entergy s external customers and constituents Corporate Citizenship The next power plant Customer Service and power reliability Entergy s internal customers Enhanced forecasting Accurate meter reading and billing Reduced line loss Reduced energy theft Proactive line maintenance Improved collections and credit 9

16 Selection criteria for pilot area The selected location must provide a test base for targeted functionality Accessibility to key external and internal stakeholders PSC Key Entergy stakeholders 16

High potential for connects/disconnects High potential for re-reads

17 Selection criteria for pilot area Baton Rouge, Louisiana Meets all criteria Six meter reading routes Near Louisiana State University campus High potential for connects/disconnects High potential for re-reads Availability of company personnel to install meters Gas customer base Regulatory support 17

18 Technology and vendor selection criteria Ability to meet functionality Ability to meet schedule Cost Vendor viability and proven Intangibles 18

19 Technology Selection AMI Mesh Network 19

20 The Value Proposition of a mesh network for Entergy Controlled installation and maintenance costs Plug & Play installation The meter population is the mesh network Proven two-way AMI technology mesh network Largest mesh network provider in the world +1.3MM smart meters deployed globally Dynamic and controlled mesh network Self Healing Secure Self registering Standards based open system for future growth 20

21 Mesh Network Auto-registration 1.Collector meter looks for unregistered nodes Collector is a single phase or polyphase meter with WAN & LAN boards 2.Collector checks for reliability and registers Level 1 nodes Nodes can be either polyphase or single phase meters Collector Level 1 21

22 Mesh Network Auto-registration 1. Collector looks for unregistered nodes 2. Collector registers Level 1 nodes 3. Collector registers Level 2 nodes & repeaters 4. Collector registers Level 3 nodes & repeaters Collector Level 1 Level 2 Level 3 Level 4 5. Network continues to build out to a max of 8 hops (7 repeater levels) or until maximum collector setting Level 8 22
