Tier 2 Power Supply Planning Workshop Advanced AMI Benefits Overview

Key Performance Objectives Goal – Leverage the City’s AMI System investment Advanced features and functionality Suggested Next Steps & KPO’s Water meter right-sizing Electrical transformer right-sizing Continue Demand Response program Implement annual meter inspection program Utilize outage notification system Water system main leak detection Establish redundant fiber optics to collectors Leverage meteorological data to predict system peaks Continue Customer communications program Distribution automation & Integration of SCADA

AMI AMR Remote Usage Gateway Into Home System Modeling Infrastructure Security Customer Profiling & Data-logging Leak Detection, Locating and Repair Predictive Maintenance Water Quality Monitoring Outage Management Emergency Shut-off and Repair GIS Mapping / Asset Management On Demand Reading Theft Detection Customer Web Access Remote Disconnect Customer Leak Detection Backflow Detection Sub-metering Services Time of Use Demand Response Unmeasured Flow Reduction Emergency Alerts System Management Planned Repairs and Maintenance Audit and Revenue Enhancement Vision System Inspections Flow / Pressure Monitoring Smart Water & Electric Infrastructure Contamination Monitoring Equipment Status Monitoring Repair / replace instructions Smart Pipe & Pipe Pigs Smart Infrastructure

Leverage AMI Hourly Data Water Meter right-sizing By monitoring the hourly flow through meters, the City could verify water meter sizing is appropriate and replace meters as needed High flow – could prevent meter burst Improves revenue by improving accuracy Ensure Electric Transformers are not Overloaded By aggregating the individual hourly meter data by transformer, the system can estimate the average load Prevent emergency replacements Better utilize under-loaded transformers

Easily Identify Potential Overload Failures Planned replacements instead of emergencies Requires City Inventory & meter links Transformer Loading

Continue Demand Response The City is taking a major step with enabling Demand Response in 2011 and evaluating the benefits in 2012 Don’t stop now; Port Angeles could be a show case community in the U.S. To maximize the benefits and better understand the impacts to both the City and it’s customers, the City should continue demand response recruitment activities in 2013 after our 2012 evaluation.

Annual Meter Inspections As part of the initial AMI system deployment, Mueller Systems is conducting a 100% audit Water meter plumbing Electric meter sockets; overhead clearance Evaluating meter clearances against codes This puts the City in a top notch position Recommendation Maintain - do not stop while you are ahead How – implement an annual meter inspection program. Does not have to be 100% every year but there should be a plan to keep up

Provide an even higher level of system reliability GIS Tool — Plotted Notifications Full outage list shown for sorting and prioritizing work Utilize Outage Notification

Distribution Side Leak Detection Mueller acquired Echologics in December 2010 Leader in acoustic leak detection technology No additional AMI infrastructure required Devices magnetically attached to valves Loggers activate and listen each night Results are collected via Mi.Net Infrastructure

AMI Backhaul Reliability There are two critical pieces to the AMI network infrastructure AMI collectors to AMI meters Mueller System is responsible Fiber Network to AMI Collectors The City if responsible Recommendation - Establish redundant fiber optics to collectors in 2012 to ensure high AMI System network reliability

Leverage Meteorological Data The Mi.Net AMI System provides a direct feed to local meteorological data from the national weather service By correlating AMI hourly consumption data with meteorological data, the system can help the City predict next day system peak hours Recommendation – use the system to help anticipate system load

Continue Customer Communications The City has started off the AMI system program with one of the most impressive and all encompassing customer communications programs in the nation This was a key issue for other large systems The City is doing everything right! Recommendation Continue to promote the customer benefits Key Areas Time of use rates Customer portal Customizable alerts Demand Response

Promote Consumer Portal Utility Messages Personalized Alerts and Notifications

Future - Distribution Automation Mueller Systems owes the City a SCADA integration and Distribution Automation Plan in the Fall of 2011 This is a new area of development for Mueller Systems and the details are still being developed Recommendation Consider long-term (2013 and beyond) integration of the SCADA and AMI System Consider AMI automation of the distribution devices such as switches and reclosers Benefits – leverage the advanced system in which you are already investing
