Solar Metering and Performance Monitoring Exposition June 4, 2007 The PG&E SmartMeter program: ► will deploy a system for automated meter reading – hourly meter reads for electric, and daily meter reads for gas ► includes two separate systems: a power line carrier system for electric and a radio frequency system for gas ► involves an upgrade to both gas and electric meters – approximately 10 Million meters will be upgraded ► will be deployed over a five year period. An initial, paced deployment began in Bakersfield in November, 2006. Deployment efforts are scheduled to conclude in late 2011 ► will introduce additional capabilities over time, including outage management and remote connect/disconnect (for a subset of electric customers) ► will enable the introduction of demand-response rates for residential and small business customers 2 Overview: Benefits Customers ► Receive usage information to better understand and manage their bills, and be able to participate in energy efficiency and demand response programs ► Experience less inconvenience and intrusion by no longer needing to unlock gates and tie up dogs for monthly meter reads ► Reduction in the causes of delayed, inaccurate and estimated bills ► Experience faster outage detection and restoration times ► Opportunity to turn service on and off remotely PG&E ► Experiences ► Improved reduced operating costs billing efficiency through reduced exceptions processing ► Experiences improved customer satisfaction ► Accomplishes goal of lower procurement costs ► Achieves reduced energy theft ► Provides improved outage management CPUC/State ► Supports the CPUC’s price-responsive tariff requirements 3 SmartMeter Program - Business Case Costs O&M 4% delta Benefits (100%) Demand Response 14% Remote turn on / off Outage detection Service restoration ISTS Deployment $189M Operations 40% Meters Call volume reductions Networks Records exception reductions ISTS O&M $191M Installations IT Systems Field Deployment System Integration $1,299M Project Management ► ► ► Avoided dispatches / truck rolls Meter Reading 46% Complex billing Capacity planning The SmartMeter program has a positive business case: Projected benefits exceed projected costs by 4% Operational efficiencies (including meter reading savings) account for approximately 86% of benefits Demand response (i.e. reduction in procurement costs) accounts for about 14% of benefits, and promises to provide an additional positive return on our investment 4 SmartMeter Dual-Network Architecture Web Server Electric powerline carrier network PG & E Substation Meter Data Management & Storage PUBLIC WIRELESS NETWORK PLC System Controller Substation Communication Equipment LOAD RESEARCH AMI Interface System Fixed Wireless Network System Data Collector Unit CONSUMER PUBLIC WIRELESS NETWORK OUTAGE MANAGEMENT RF Network System Controller Customer Information System 5 Substation Communication Equipment (SCE) Control and Receiving Unit (CRU) Modulation Transformer Unit (MTU) Outbound Modulation Unit (OMU) 6 The SmartMeter enabled electric meter will look much like standard electromechanical meter, but will include a SmartMeter electric module (i.e. remote communications equipment, or RCE) SmartMeter electric module “under the glass” Standard electromechanical meter SmartMeter Electric Module (Remote Communication Equipment – RCE) Completed Retrofit 7 The SmartMeter Radio Frequency (RF) network for gas Data Collector Unit (DCU) MTU Sends Reading Messages DCU Sends Data Network Control Cluster Reading File Gas meter with meter Transmission Unit (MTU) i.e. SmartMeter gas module WACS 8 RF network is designed for redundancy ► On average, each gas meter will be read by at least 3 data collector units (DCUs) ► The DCU reception range is approximately 1 mile ► A single DCU can handle up to 50,000 meters 9 Deployment volumes for SmartMeter gas and electric meters will ramp to a peak of over 12,000 meters per day Includes gas and electric meters 14,000 Installs per Day 12,000 10,000 8,000 6,000 4,000 2,000 0 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 35 37 39 41 43 45 47 49 51 53 55 57 59 Endpoints Deployment Month 10 Deployment volumes of SmartMeter gas and electric meters – annual view Gas and electric endpoint installations 3,000,000 2,500,000 2,000,000 1,500,000 1,000,000 500,000 0 2006 2007 2008 2009 2010 2011 10.3 Million meters will be upgraded by the end of deployment in 2011 11 Support for solar requirements ► Current SmartMeter technology supports net metering only ► A separate measure of generation would require a second meter ► PG&E continues to monitor and evaluate advances in automated metering technologies ► ► ► The CPUC asked PG&E to evaluate new technologies on an ongoing basis We evaluate against the solar requirement for a separate measure of generation Some new technologies provide this capability and we are looking at these carefully 12
