  1. Tomorrow’s Energy Grid 7th Annual Statewide Energy Efficiency Forum Riverside, CA The Energy Efficiency Foundation of Integrated Demand-Side Management Audrey Lee, Ph.D. Vice President, Analytics and Design June 16, 2016

  2. THE ELECTRICITY GRID IS CHANGING DEMAND RESPONSE ENERGY STORAGE AMS won a 50 MW Contract to Build Energy Storage Systems for Grid Support in Southern California

  3. AUTOMATED DISPATCHABLE LOAD REDUCTION

  4. STORAGE AS A SERVICE Energy Savings Services Fee Battery Storage Host Customer AMS Own & Operate Utility Utility Contract ECONOMIC MODEL

  5. OPTIMIZED DEMAND MANAGEMENT DEMAND CHARGE REDUCTION LOAD SHIFTING 1 2 3 2 UTILITY SERVICES POWER (kW) 1 3

  6. ADVANCED ANALYTICS BEFORE: Unmanaged Energy Use AFTER: Energy Management & Load Shaping

  7. Greenhouse Gas MANAGEMENT 750 kW / 3000 kWh battery model – Southern CA Medical Offices 1 June – September 2015 Carbon Management Opportunity Battery charges when power generation carbon intensity is lowest / most efficient, and generally discharges during ‘dirtiest’ (least-efficient) times. Legend: Charging (total kWh / mo) Discharging (total kWh/ mo) Carbon Emissions Benefit: 1035 metric tons CO2 / year avoided Carbon intensity mapped using WattTime data for marginal carbon emissions in the California Independent System Operator (CAISO) CVR Methodology: for every % of line loss efficiency achieved on a 10,000 kW circuit using distributed storage = 136 metric tons CO2 / year avoided Adapted from Application of Automated Controls for Voltage and Reactive Power Management – Initial Results. DOE – Smart Grid Investment Grant Program, December 2012

  8. CASE STUDY 01 INLAND EMPIRE UTILITIES AGENCY • 6 water recycling, pumping facilities • Powered from the grid and onsite generation assets • 3.75 MW energy storage (AMS) • 3.5 MW solar • 3 MW biogas • 1 MW wind • 2.8 MW fuel cell • 5-10% reduction in annual energy costs(~$550,000) • Complex existing tariffs: RES-BCT, Standby, Direct Access, NEM • Custom designed

  9. Solution Design, Optimization Optimized load Charging battery with Solar in off- and mid-peak Discharging battery to reduce load in late evening Biogas ICE Production • 500 kW / 1 MWh Energy Storage • 1 MW Solar • 1.5 MW Biogas Digester • RES-BCT, SCE-TOU-8B tariff

  10. CASE STUDY 02 IRVINE COMPANY • 22 commercial office buildings • 25% peak demand reduction • 10 MW of firm, dispatchable capacity to the utility • 8% reduction in energy costs to the building owner (~$900,000 annually) • Zero emissions • No distribution upgrades

  11. CUSTOM-FITTED WITH ENERGY STORAGE

  12. CASE STUDY 03 CITY HALL • Typical Office Space • Active 5 AM to 9 PM • 3 Meters • Time-of-use energy and demand charge

  13. ANALYTICS SOFTWARE
