  2. Customer-Facing Subcommittee Mtg. #1 Agenda (1/9/13) • Briefing on Time Varying Rates, Metering, and Customer-Facing Regulatory Policies and MA Utility Pilots • NSTAR-- Doug Horton, NSTAR & Stuart Schare, Navigant Consulting; GRID--Peter Zschokke; & Unitil--Justin Eisfeller • Time-Varying Rates • Subcommittee View Sharing and Discussion • Metering/Data Communications • Speakers: Itron Smart Grid Solutions: Bruce Husta; AvCom Corporation: Fred Avila; & Sentinel Works: Jim Hirni • Regulatory Policies • Subcommittee View Sharing and Discussion

  3. Unitil: Pilot Program Results 3

  4. NSTAR Preliminary Results: Load reductions during summer events vary with the rate and technology Preliminary Findings * Findings based on two events in Summer 2012, with simple baseline load estimation Automated load control via thermostats achieves reductions of 0.7 – 0.8 kW CPP rate without thermostats saves ~0.2 kW Technology group shows savings, but negligible 4 4

  5. Pilot Evaluation Timeline Technical Performance Report #1 Technical Performance Report #2 Metrics & Benefits Report Metrics & Benefits Report End of PilotOfficial DOE Pilot Kick-offSoft Launch Final Report to DPU Interim Report to DPU 24 months Summer 2010 September 2012 January 2012 Summer 2013 Winter 2013 December 2013 Spring 2014 Pilot StartOfficial DOE • NSTAR Pilot will run through 12/31/2013 with the final evaluation to US DOE and MA DPU due April 2014. 5 5

  6. NGRID: Customer Choices New Rates Hourly Pricing Program (HPP) Critical Peak Pricing (CPP) Peak Time Rebate (PTR) 6

  7. NGRID: Results To Date • Early Field Trial (EFT) meters in place since March 2012 • 5,000 meters • Tested communications • Tested reading of meter data • 299 customers opted out of meter (5.97%) • Remaining 10,000 meters scheduled in service by May 31, 2013 • Pilot start date scheduled for January 1, 2014 • Provides 2 years of baseline data for summer use for 5,000 customers and one year for 10,000 meters

  8. Is Hybrid Drive-by or AMR Fixed Network a Realistic Alternative [to AMI]? (Software/HAN or ChoiceConnect) • Allows customer interaction • Allows appliance control • Interval data for flexible pricing (TOU, RTP, CPP, etc.) • On demand reads • Realistic additional cost AvCom Presentation

  9. Customer-Facing Subcommittee Mtg. #2 Draft Agenda (2/26/13) • Alternative Metering Scenarios, Functions, Costs for Massachusetts • Presentation of Subcommittee’s working group on scenarios, functions, & costs • Utility current meters and meter practices • Time-Varying Rates (Subcommittee View Sharing and Discussion) • What opportunities will time varying rates enable, and how essential are they to developing a truly modern electric grid? • What time varying rate options hold the most promise for MA and why? • Should basic service be structured as time varying rate(s)? What about T&D rates? • What do competitive suppliers need to be able to effectively offer time varying rate options? • Principles and Regulatory Policies for Time Varying Rates and Advanced Metering • -Brief Presentation on Potential Principles—Barbara Alexander, Consumer Affairs Consultant to MA AG • Readings from NASUCA and Faruqui • What principles should be considered around time varying rates and meters, including any recommended consumer protections? • What is the appropriate pace for implementation of customer-facing grid modernization? • What regulatory policies should the group consider? • Planning for Final Two Subcommittee Meetings

  10. Grid-Facing Subcommittee Mtg. #1 Agenda (1/14/13) • Briefing Grid-Facing Options and Opportunities • David Malkin, GE • Successful Grid-Facing Modernization—10-20 Years from Now • Utilities: Jennifer Schilling & Larry Gelbien, NU; Chris Kelly, NGRID • Clean Energy Coalition: Ram Rao, Ambient • Utility Planning and Decisionmaking on Grid-Facing Investments • NGRID--Chris Kelly; NU--Larry Gelbien; & Unitil--Kevin Sprague • Subcommittee View Sharing and Discussion: Grid-Facing Modernization

  11. Grid modernization maturity levels Apparatus………..Physical grid devices Protection…………Devices to reduce injury or equipment damage Monitoring...........Maintaining safety, reliability & quality Metering……………Load management, billing, & system stability Control………………Operating apparatus & control of power flows SCADA……………….Supervisory Control And Data Acquisition Automation………Automatically monitoring & controlling devices Optimization…….Improving economics, efficiency, reliability & safety

  12. Technology taxonomy… DOE’s view Source: US Department of Energy, Impact of Smart Grid Projects Funded by the Recovery Act of 2009

  13. Technology taxonomy… NEMA’s view(Grid Resiliency) • 1. Smart Grid Solutions • Smart meters /AMI • Feeder automation • Fault detection, isolation, restoration • 2. Microgrid & Energy Storage Solutions • Microgrid controllers • Distributed generation • Distributed energy storage • 3. Hardened Equipment • Wiring • Cabling • Electrical components • 4. Back-up Generation • Diesel or NG generators • Batteries, fly-wheels, etc. • 5. Equipment Repositioning • Elevating back-up generators • Substation siting Source: National Electrical Manufacturers Association,

  14. NGRID: What will the Customer See… Now to 5 Years 5 to 10 Years 10-25 Years Transformed Grid True Two-way Power Flow Transaction-less Renewables Automated Home and Businesses Multiple Value Services Value Based Services Two-way Power Flow Opportunities Integrated Demand Response Smart Appliances and Standards New home area networks Secure Renewables Two-Way Comms OMS/DMS Real-time Optimization Integrated Voltage Control Anticipate outages, Continuous optimization, and pin point accuracy of system trouble and restoration Urban, Suburban Reliability Metrics Pockets of Performance Develop Value Services Grid Sensing Next Generation Automation Outage Management Two-way Comms Converging Cyber Security Web Services Applications and Data Energy Efficiency Faster Interconnects Safe, Secure, Reliable and Resilient System 15

  15. NU: The Smart Grid Benefits All Stakeholders The Smart Grid will create a digital energy system that integrates new tools and technologies from generation, transmission, and distribution all the way to consumer appliances and equipment. Self-Healing Wide-Area Protection Distributed Generation & Alternate Energy Sources Optimization and Improved System Efficiency Asset Management and On-Line Equipment Monitoring Source: Adapted from EPRI.

  16. Ambient (Clean Energy Coalition)Smart Grid Emerging Technology Roadmap Incremental (0 – 3 Years) Strategic (3 – 10 Years) Transformational (10+ Years)

  17. Unitil: Goals and Objectives * U.S. National Energy Technology Laboratory

  18. Evaluate Options Unitil: Distribution Planning Approach Recommendation Identify Concerns System Modeling

  19. NU: Project Selection Methodology • The process evaluates the customer service impact and considers expenditure to create a cost benefit analysis • Other Considerations used in the Project Selection Process: • Municipal or DPU Commitments • Communities with historically lower reliability performance (low months between outage) • Effect of outages on customers (Significant hardship versus minimal impact) • Environmental and safety concerns • Asset age and performance • Service quality metrics

  20. Grid-Facing Subcommittee Mtg. #2 Draft Agenda (2/26/13) • Potential Grid Modernization Framework & Outcomes for Massachusetts • David Malkin, GE presents on behalf of Subcommittee’s working group • PotentialOptions & Strategies for Fast Two-Way Communication • Potential Options & Strategies for Seamless Two-Way Energy Flow • Potential Options & Strategies for Voltage/Var Control • Kelly Warner, Applied Energy Group • Subcommittee View Sharing and Discussion: Grid-Facing Modernization • What are the most important grid-facing improvements needed? • What is the appropriate pace for implementation of grid-facing grid modernization? • What are the most important criteria used to make grid-facing investment choices? • What regulatory policies should the group consider? • Planning for Final Two Subcommittee Meetings
