3 Introduction to Enwave: Enwave North America Enwave is located in 7 cities in North America, and is actively in pursuit of expansion through acquisitions and system development opportunities Enwave Seattle District heating in Seattle Enwave Toronto District heating and cooling in downtown Toronto Enwave Las Vegas District heating and cooling in Las Vegas Enwave Windsor District heating and cooling in Windsor Enwave Chicago District cooling in downtown Chicago Enwave Houston District cooling in downtown Houston Enwave New Orleans District heating and cooling in downtown New Orleans 2

4 Introduction to Enwave: Enwave North America Enwave operates District Energy Systems using various technologies in the following major cities: TORONTO HOUSTON NEW ORLEANS CHICAGO SEATTLE 8 steam plants (2,700,000 pph) and 3 hot water plants Deep Lake Water Cooling ( DLWC ) system and mechanical chillers (240,000 tons) Ice on coil storage tanks (400,000 tons) 490 customers including universities, governments, hospitals, hotels and commercial buildings In addition, Enwave operates plants in Las Vegas, NV and Windsor, ON 3

5 Enwave Technologies: Now and Beyond Current Future Deep Lake Water Cooling Ice storage Heat pump Off-peak storage High efficiency boilers Biomass Electricity from Steam o o o Thermal storage Battery storage Ice storage CHP Low carbon fuels Geothermal CHP Enwave is continuously improving and growing our roster of energy technologies 4

6 Heating Load Heating Load Enwave Advantage: Leverage the District Stand-Alone Building Base Electrical Demand Building Heating Profile Unutilized CHP Electrical Generation CHP requires simultaneous electricity and heating demands No summer heating demand prevents CHP from running year-round Summer Winter Summer Leveraging District District Heating Load Unconstrained CHP Electrical Generation Summer Winter Summer Base Electrical Demand Leverage the District Loop, allowing for unconstrained electrical generation Export surplus heating generation to the District CHP runs to the electrical demand of the building 5

7 Enwave Advantage: Reduce Operating Risk with Enwave Deal Parameters Benefits Enwave manages operations of the CHP plant Tailored financial structure can include: Enwave finances all project capital Enwave billings can include: o Management fee o Capacity charge o Consumption charge Enwave manages entire process from feasibility study to operations Highly-trained operations team Established Operating and Maintenance procedures and program Established annual training program Develop and integrate dispatch tool Constant monitoring of equipment efficiency Reduce required focus, time and effort of management team Monitor operating cost Continuously monitor market conditions De-risk from commodity markets Predictable cash flow Avoid unexpected capital expenditures Enwave can provide a reliable, simple and tailored turnkey solution 6

8 CHP and Enwave: Enwave s Optimized CHP Solution The Enwave option is a three-phase solution 1 Design Enwave will work with the building to design the optimal CHP solution 2 Install Enwave will manage the installation of the CHP plant 3 Operate Enwave can operate and manage the CHP plant 7

9 Design: Finding the Optimal Solution CHP Considerations CHP Options Location Hot Water Configuration Environmental Constraints Building Energy Balance Implementation Plans Current Building Operations Steam Configuration Low Pressure Steam Configuration Steam Plant Enwave considers various building factors before selecting and designing the optimal CHP solution 8

10 Design: Hot Water Configuration Option Natural Gas Air SCR Exhaust Gas Steam Boiler Exhaust Gas < 230 F Lubricant Oil Final Heat User Electrical 140F 180F Hot Water 180F Building 1, 2, 3,.. Backup cooler 140F. 130F V = f(t) 110F Enwave Distribution System Engine Cooling Water / Oil Heat Exchanger From Condensing Economizer - 160F 9

11 Design: Steam Configuration Low Pressure Option Natural Gas Air SCR Exhaust Gas Steam Boiler Exhaust Gas < 230 F Lubricant Oil Electrical 140F 180F DA 227F Final Heat User Steam 5-15 PSIG Steam Building 1, 2, 3,.. 15 PSIG Thermostat Backup cooler 190F. 190F V = f(t) Condesate 110F 170F Enwave Distribution System Engine Cooling Water/ Oil Heat Exchanger From Condensing Economizer - 160F 10

12 Design: Steam Configuration Steam Plant Option Natural Gas Air SCR Exhaust Gas Steam Boiler Exhaust Gas < 230 F Lubricant Oil Steam 7 PSIG Steam Boiler Final Heat User Electrical Backup cooler 140F 180F DA 227F. V = f(t) 190F Steam 200 PSIG Building 1, 2, 3,.. Thermostat Enwave Distribution System Engine Cooling Water / Oil Heat Exchanger 40F-110F From Makeup Water/Condesate 11

13 Design: Where are we heading? Toronto Hydro Steam Enwave and Toronto Hydro can partner to manage the distribution of renewable resources to multiple users 12

14 Install: CHP Installation Experience Enwave has successfully installed a 4 MW CHP plant in the basement of our existing steam plant and our management team across North America has 50+ year experience with CHP and in the Power Generation industry Enwave was able to find ways to optimize the initial design that resulted in the following: Cost reduction: installation and on-going operations costs Repurposed underutilized basement space Leveraged existing infrastructure Integration of CHP plant with Enwave district The Pearl Street Energy Plant exemplifies Enwave s ability to deliver an optimized CHP plant 13

15 CHP and Enwave: Leverage Enwave s Experience on Path to CHP Feasibility Design Equipment Procurement Installation Commissioning 6 Months 6 Months 3 Months 8 Months 1 Month Navigating compliance and approvals Tailored financial structure Experience from seven businesses across North America Strong relationships with designers, contracts, and suppliers Strong relationships with equipment suppliers Leverage Enwave s purchasing power Experience installing 4MW CHP plant Experience installing 11 MW steam plant Optimizing construction sequence Seamless system integration All systems operating as designed Equipment operating at peak efficiency Integrate CHP into building ecosystems Minimizing construction risk All documentation is updated as commissioned Provide full steam back-up through Enwave district Reduce project cost All regulation conditions are met Enwave s depth of experience can help you properly navigate through the 2+ year process 14

16 CHP and Enwave: When to contact Enwave? When financing assistance is required When design and installation expertise is required When there is opportunity to maximize heat utilization by building distributed energy networks When evaluating building energy needs Enwave will work with you to address the building s needs 15

18 Appendix: Pearl Street Energy Plant 17

19 Appendix: Pearl Street Energy Plant Initial Concept The CoGen was located outside the plant Single Engine: 4 13,800 V Challenges: o Expensive: installation, operation, maintenance o Limited real estate o Noise compliance o Electrical: required additional electrical protection o Plant Integration 18

20 Appendix: Pearl Street Energy Plant Optimized Design The CoGen is relocated to the plant basement Two Engines: V Advantages: o Cost Effective: installation, operation, maintenance o Leverage underutilized basement space o Electrical: more common electrical equipment, reuse existing infrastructure o Plant integration: use available chilled water as emergency cooling, heat rejection to existing plant systems 19
