3 PHI s Smart Grid Modernizes the grid while utilizing existing wires, transformers and substations Lays more sophisticated information delivery system over electricity delivery system Brings new advanced meters, sensors, communications equipment, automation and computers to the existing grid Collects and transmits data wirelessly Provides valuable energy cost and usage information to customers and system performance to operators Promises significant advances in load reduction, customer service, outage detection, service restoration, and system operations & planning Facilitates deployment of renewable / green energy alternatives

4 Path to the Smart Grid PHI began its Smart Grid planning in 2005 and has been progressing rapidly in its implementation 2007 Blueprint for the Future Filings 2005 Utility of the Future vision 2008 Smart Grid Design/ Technology Selection 2009 SGIG Awards Made 2009 AMI Field Acceptance Testing 2009 AMI deployment began in DE 2010 AMI deployment Began in DC Continued Smart Grid advancement MD PSC approval of DLC 2008 DE PSC approval of AMI 2009 NJ BPU approval of DLC 2009 DC PSC approval of AMI 2010 MD PSC approval of AMI

5 Success Stories: Advancing the Smart Grid Regulatory authority to move forward Delaware, District of Columbia, Maryland American Reinvestment & Recovery Act DOE $173.5 million awarded Maryland $104.8 District of Columbia $ 44.6 New Jersey $ 18.7 Smart Grid Workforce Training Grant $ 4.4 Smart meter installation Under way in Delaware since 2009, in the District of Columbia since 2010 and in Maryland since June this year

6 5 evolutionary steps to achieving the Smart Grid Smart Grid Investment Grant (SGIG) funding accelerated this process Step 5 Maturity Step 1 Intelligent devices infrastructure: AMI, or Smart Meters Distribution Automation Devices Demand Response Devices Substation IED Controllers Step 2 Communications infrastructure: Enterprise communication system for rapid and accurate transmission of data Integration of fiber and mesh broadband networks Step 3 Integration: Corporate IT systems integrated to allow rapid processing of data Open architecture based design to facilitate sharing of information Step 4 Analytical infrastructure: Development of new data analysis capabilities Increased ability to display information (in form of dashboards, etc.) Optimization: Capability of realtime optimization of distribution network performance Decisions based on near real-time information, no longer only historical data Capability Adapted from IBM Copyright 2011 Pepco Holdings, Inc. 5

8 Transition to Smart Substations Analog Substations Separate relays for each event Limited situational awareness Visual confirmation of failure event Limited station communication to Control Center Digital Substations Multiple events managed by Smart Relays Increased situational awareness and analysis of events Increased status communication to Control Center

9 Feeder Automation Automatic Sectionalizing and Restoration Scheme Protects customers from sustained outages caused by feeder lock-outs Segments feeders into 2, 3, or 4 sections using remote controlled switches or Automatic Circuit Reclosers (ACR s) in the field For a fault in any one section: ASR opens closed switches to isolate the section ASR restores the other sections by reclosing the feeder breaker and/or closing open tie switches to other feeders Generally ASR operates in less than a minute 1 year Field Test yielded 7 operations and over 50% improvement in feeder performance Number of Customers /13/ Customers Experiencing a Sustained Outage /30/2008 Scheme Not Initiated - High Magnitude Fault Alarm /6/ /24/ Scheme Not Initiated - RTU Out of Scan /25/ /13/2009 Occurrences Since June 13, /23/ without ASR with ASR

12 Smart Grid Benefits for Renewable Energy Net Metering and Net Billing, which support and encourage solar installations, become easier to implement because AMI smart meters can separately record flows of energy in each direction AMI enables the increased use of solar by making it easier to integrate them into the grid With AMI enabled dynamic pricing customers with solar can lower energy costs by monitoring prices and choosing to use more of their solar resources during peak pricing Customers with solar will not have to compromise by reducing electrical usage during peak pricing periods

13 Smart Grid Future-PHI Plug-In Vehicles PHI is currently working with EPRI to evaluate the Ford Escape PHEV Have 10 Chevy Volts Smart Grid technology will allow for full integration of PEVs into grid 2 EVs equal approximately one average house load Charger control will reduce risk

14 Key Takeaways The smart grid will only work to the extent that customers win, Joseph Rigby, CEO of Pepco Holdings Customer Adoption and Participation is a key enabler Smart Grid will move at the Speed of Value Interoperability and Standardization are not spectator activities. Utilities need to get involved and make their voices heard and be engaged as individual companies and as an industry Through the Smart Grid, Utilities will become Technology Companies No longer the best solutions but rather iterations of Better Solutions Similar to Electric System Operations, Communication Network Operations and enhanced Cyber Security will become part of our future DNA
