12 Delivery Rates and Cost Recovery Some Electric Rate Components Demand Charges: $20 - $40/kW/month Energy Supply: $ $0.08/kWhr Demand Response ConEd $5/kW/month NYISO $12/kW/month 12

13 Con Edison Energy Storage Projects Nickel Zinc Flow Assisted Battery CCNY Energy Institute Storage integrated with PV DOE Stimulus Grant Demonstration Project Transportable Li-Ion Energy Storage System Electrovaya and NYSERDA EOS Zinc Air Demonstration NYSERDA Project to Demonstrate Low Cost, Safe, Reliable and Long Life Battery 13

14 Flow Assisted Zinc Anode Battery Reduces Dentrites 100 KWh integrated into building service Zinc is cheap, nontoxic and widely accessible CCNY Nickel Zinc Battery 14

15 Electric Vehicle Charger, PV & Battery Storage Integration GreenStations integrating Electric Vehicle charging Battery charging and discharging Photovoltaics Peak Shaving Monitoring and control of multiple GreenStations via Network Operations Center (NOC) Near real-time energy and demand monitoring Near real-time targeted demand response 15

16 7 Eleven Queens GridSynergy TM Execution GreenStation TM 40kW, 150kWh, Smart Controller, with L2 EV charging Solar Panels on roof EV Charging Level 2

17 Peak shaving example Avoided Actual Panel Load Battery Charge / Discharge Solar PV 10kW system *First SSGU system of its kind installed in Queens, NY

18 Transportable Energy Storage System (TESS) Demonstration Co-funding from NYSERDA, Electrovaya and Con Edison Battery Room Electrical Control Room (contains PCS/transformer) Fire Suppressant Tank HVAC Transportable Energy Storage System. Trailer Bed 800 kwhr Storage Capacity, 500 kw Power Rating 40 x 8 x 12 ½ ft trailer weighing 60,000 lbs Batteries, PCS, HVAC, Fire detection/suppression systems integrated within a transportable container Connection at customer voltage levels Programmable to charge off peak and discharge during peak load periods 18

19 TESS Applications and Benefits Grid support and emergency backup Infrastructure Upgrade Deferral e.g. Distribution Transformer Sensitive sites - No emissions, Less noise Energy Cost Savings buy power at off peak Installed Capacity NYC region values are higher Power Quality Voltage Sags, interruptions 19

20 Meeting with FDNY Introduce the Project Overview Safety by design Fire suppression system First Response Guide Get FDNY input and guidance Hazard Risk Analysis 20

21 EOS Zinc Air Battery Demonstration DEMONSTRATE A 6KW BATTERY SYSTEM AT A CON EDISON OWNED FACILITY TESTING TO EVALUATE KEY PERFORMANCE METRICS DEVELOP USE CASE TO DOCUMENT BENEFITS 21

22 Other Energy Storage Projects AES 8 MW Li-Ion Johnson City, NYS AEP Fleet of kw Li- Ion CES Ice Storage at Durst, Barclay, Credit Suisse, Bank of America and Verizon Buildings Demand Energy 100kW ALA at Barclay Towers, NYC 22

23 Value of Demonstration Understand permitting and site prep issues Verify technical capability Real cost of operating and maintaining the system Develop decision-making tools Evaluate cost benefits Obtain operational experience Evaluate environmental benefits Evaluate use in Emergencies 23

24 Location Impacts Regional/State Regulatory/Policy Uncertainty Zones - Value of Services e.g. Installed Capacity Municipal Requirements DOB, FDNY Utility Grid - Con Edison highly congested, networked, and underground Space Constraints Interconnections Load Profile and Duration Thermal load Relief 24

25 What Utilities Need Economic Decision Tools Tailored for Energy Storage EPRI s ES Valuation Tool is a Good Start Uniform Performance Protocols and Standards Uniform way of measuring, quantifying, and reporting the performance of ES in various applications Standard Specifications for ES Procurement ES Systems that Are Grid Integration Ready 25
