1. 1 Overview of Maryland Pepco and Delmarva Power Spring 2007 Blueprint for the Future Filings Tom Graham, President Pepco Region Maryland Commission Hearing -- Annapolis July 26, 2007

2. 2 Motivation for Pepco and Delmarva Blueprint Filings Higher Regional Energy Costs – Blueprint Plan facilitates Maryland customer control over electricity bills and places downward pressure on PJM market wholesale energy and capacity prices. MADRI/Commission/PJM Brattle Study recently calculated that a 3% reduction in peak electricity demand would reduce regional electricity prices annually by $57 million to $182 million. Demand response capabilities mitigate generator market power. Constrained Regional Transmission Import Capability – Blueprint Plan reduces future peak electricity demand to lessen burden on transmission system. Growing Environmental Concerns over Power Plant Air Emissions – Blueprint Plan reduces future power plant air emissions and resulting greenhouse gases.

3. 3 Motivation for Pepco and Delmarva Blueprint Filings (continued) Availability of New Electric Distribution System Technology –Blueprint Plan uses new tested technology to enhance distribution system operation, improving service quality, reducing electric distribution operational costs, supporting demand side management initiatives – including both dynamic pricing and new demand response technologies, supporting renewable generation technologies, and supporting future plug-in vehicles. Plan Benefits vs. Costs –Blueprint Benefits will be Significantly Greater than Costs for Maryland Pepco and Delmarva Customers –DSM Proposals are Cost-Effective and were Tested Using All Ratepayers Test (Pepco and Delmarva recommend Commission adoption of Societal Test) –AMI Utility Specific Business Case to be Shared w/Maryland Stakeholders in the Near-term –Significant Regional/National Benefits from Resulting Reductions in Greenhouse Gases

4. 4 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
