7 Technology choices today Mesh Tower PLC Point to Point Speed Fast Fast Slow Bandwidth Broad Narrow Narrow Scalability High Low High Broadcast Speed Medium Fast Slow WAN Choice Fixed Fixed Interference Technology Does Prevent Technology Does Not Prevent No Interference License Unlicensed Shared Bandwidth License Protects Right to Exclusive Bandwidth NA Risk of Frequency Re-allocation Very Low Low NA Contention Low (Distributed Path) High (Bubble Up) Low Redundancy Easy (Add gatekeeper) Difficult (Add Towers) None Self Healing High Low None Data Throughput Reliability High (Every Network Element is Repeater) Low to High (Varies with # of Towers and Repeaters Deployed) High

8 Generation 2 RF Mesh Quadrupled bandwidth Improved latency Extended reach 2400 feet planning hops (vs ft. in G1) 16 hops per subnet (vs. 8 hops in G1) 8

9 Network Bandwidth 10% or less of network capacity used today 1-2 seconds per on-demand read 9

10 Operational IT and Communications Convergence IP AxisLink enables connection of SCADA devices to the AMI infrastructure avoiding the cost to extend or add a separate DA communication network. 10

17 Obstacles to Building a Smarter Grid Capital investment required Uncertain payback period Complexity of design, build & operate decisions Death by Pilot Attitude Its really just enhanced AMR, isn t It? Perceived lack of solution flexibility & fear of technology obsolescence We also supply water/gas Confusion over best course of action What works best in hardware, software, network? Whose technology platform for desired results? Where/when/how should I start? What do I need/afford today? Tomorrow? 17

18 What s Creating a Burning Platform for Change? Rising energy costs Demand growth projected for next years Aging infrastructure including 1-way load control Retiring work force of the best and brightest Systemic system losses in water, gas & electric business operations Rising number of disconnects for non-pay and related charge-offs Regulation, policies and activists legislation Rising expectations of customers for reliability and innovative programs Impact of technology advancements on distribution system from plug-in vehicles, distributed generation, solar & wind energy 18

19 What Are The Available Options? Do Nothing Customers are not waiting to implement new technologies Customers are not reducing consumption or demand for energy System losses are not getting better Employees will retire Infrastructure will not be getting any younger Build, Own & Operate Lack of capital Complexity of decisions increase risks and price of failure Technology integration is difficult to obtain & maintain and at the same time is absolutely critical to driving benefits Business needs will change making it difficult to future proof applications What Other Options Are Available? 19

20 Smart Grid as a Service: Potential Benefits Accelerated deployment to realize maximum benefits Low initial cost Paid for solution out of savings generated from implementation Defer payments until savings begin to accumulate Reduced total cost of ownership over lifecycle Reduce risks of technological obsolescence Reduce risks of design, build and operate Eliminate integration service support issues Enable new market driven offerings (prepaid, TOU) Platform to build on for advanced applications 20
