  1. NARUC/FERC Collaborative on Demand ResponsePepco and Delmarva Power Blueprint for the Future Filings J. Mack Wathen July 15, 2007

  2. Motivation for Pepco and Delmarva Blueprint Filings • Higher Regional Energy Costs – Blueprint can help reduce and stabilize electricity costs • Impact of Energy Use on the Environment

  3. Our Customers tell us they want… • Reasonable energy costs • Reduced volatility in price • Reliable service • Environmental stewardship • Information to make choices

  4. PHI Blueprint Filings • Delaware Delmarva Power Filing -- February 9, 2007 • Commission Established Working Group Process • Maryland Delmarva Power Filing – March 21, 2007 • Commission Established Working Group Process • Maryland Pepco Filing – March 21, 2007 • Commission Established Working Group Process

  5. PHI Blueprint Filings (continued) • District of Columbia Pepco Filing – April 4, 2007 • Commission Established Regulatory Case • “PowerCents DC” Smart metering pilot underway • Each Blueprint Plan Includes: • AMI Universal Deployment for all PHI Electric/Gas Distribution Customers • Utility Provided Energy Efficiency Programs • Utility Provided Demand Response Programs • Each Plan Specific to Each Jurisdiction • New Jersey Atlantic City Electric Filing – Planned for later in 2007 • Other components of Blueprint include Distribution System Automation; conversion of our 2000+ vehicle fleet to alternative fuels including hybrids, bio-diesel and other technologies; “Energy Know How” tools

  6. Key PHI Blueprint Initiatives • Energy Efficiency/Conservation Programs • Reduce Annual Electricity Use • Demand Response Programs • Reduce Summer Peak Electricity Demand • Advanced Metering Infrastructure • Improve Distribution System Operation • Improve Customer Service • Provide Interval Consumption Data through Remote Readings • Support Demand Response through Dynamic Pricing and Direct Load Control Technology Capability • Support Small Renewable Generation/Plug-In Vehicles

  7. DSM Program Selection Process • Commercially Available DSM Measure • Applicable to Mid-Atlantic Market • Screened for Cost-Effectiveness using All Ratepayers Test (ART) • Avoided Energy Prices Derived from MD SOS Prices • Avoided Capacity Prices Derived from Cost of New Generation Entry and Regional Transmission Constraints • Approx. 370 DSM Measures Screened for Cost-Effectiveness • 65% Projected to be Cost-Effective Under ART • Additional Measures Would Pass if Societal Test Used and Value of Reduced Negative Externalities Estimated • Pepco/Delmarva Power DSM Programs Intended to be a Starting Point for Utility Specific Collaboratives • Measures Expected to be Cost-Effective Packaged into Programs

  8. Delmarva Power/Pepco Recommended Utility DSM Programs • General Awareness Campaign – Customer DSM Education/Marketing Effort • Residential Programs • Home Performance w/Energy Star: Home Audit Based Program • HVAC Efficiency: High Efficiency Central AC/HP and Training Program • Lighting/Window AC Program: Compact Florescent Lighting and High Efficiency Window Units Program • Smart Stat: Remotely Controllable Programmable T-stat Central AC/HP Program

  9. Delmarva Power/Pepco Recommended Utility DSM Programs (continued) • Non-Residential Programs • Building Commissioning and O&M: Consulting/Engineering Services to Improve Efficiency of Buildings • HVAC Efficiency: High Efficiency HVAC Equip. up to 30 Tons and Contractor Training • Prescriptive: Energy Efficiency Measure Incentives for Electric Motors and Lighting • Custom Incentive: Site Specific Efficiency Measures • Smart Stat: Remotely Controllable Program T-Stat Program • Internet Platform: Web-based Platform to Facilitate Participation in PJM Demand Response Market

  10. Pepco and Delmarva Power DSM Forecast Impact After Three Year Initial Implementation • Residential • 85.8 MW Peak Demand Reduction • 135,906 MWh Annual Energy Reduction • 265,459 Participants • 1,245,648 DSM Measures • Non-Residential • 234.5 MW Peak Demand Reduction • 433,124 MWh Annual Energy Reduction • 37,032 Participants • 5,429,706 DSM Measures

  11. AMI Benefits Include… • Remote Meter Reading • Eliminates Need for Meter Reader and improves accuracy • Supports Enhanced Customer Service Capabilities • Customer Specific Load Research Data • Demand Response • Communicates w/Demand Response Enabling Technology • Supports Dynamic Pricing Options • Enhances Customer Control Over Monthly Bills through Detailed Consumption Data • Distribution System Monitoring • Improves Distribution System Design, Reliability, and Performance • Distribution System Asset Management • Outage Reporting • Increased Accuracy of Repair Crew Dispatch • Remote Service Disconnect • Reduces Utility Service Visits

  12. Proposed Cost Recovery • Bill Stabilization Adjustment • Distribution Rate Decoupling Mechanism Removes Utility Financial Disincentive to Offer/Support DSM • Only Applicable to Distribution Portion of Bill • Proposed in Delmarva Power/Pepco Current Distribution Base Rate Cases • DSM Surcharge • Non-Bypassable Distribution Surcharge • Rate Class Differentiated • 5 Year Recovery of DSM Costs • Interest on Unrecovered Costs at Utility Allowed Rate of Return • Similar to Maryland DSM Surcharge in Existence During the 1990s • Proposed AMI regulatory approach • Timely Recovery of AMI Capital Costs Over 15 Year Period to Reflect Expected Equipment Life • Accelerated Cost Recovery of Existing Meters Over 3 to 5 Year Period • Recovery of Demand Response Smart Thermostat Capital Cost Over 15 Year Period

  13. Blueprint Path Forward • Pepco and Delmarva Power are Prepared to Begin the Implementation of their Blueprint Plan Now • The Plan Will: • Help Customers Manage Higher Energy Costs • Help Reduce Overall Regional Wholesale Electricity Market Prices • Lessen Burden on Increasingly Constrained Regional Transmission • Reduce Future Power Plant Air Emissions • Improve Distribution System Operations • Improve Utility Customer Service • Take Advantage of New Technologies • Implementation Delay will Lengthen the Period Before these Benefits are Available to Consumers
