1 CNG Station Considerations Trillium USA Presented by Bill Zobel May 25, 2010

2 Trillium s Profile Formed in 1994 Design, build, and operate CNG stations Customer base includes Transit Agencies, Municipalities, School Districts, Private and Airport Fleets Dispense 40M therms (32 MM DGE) of CNG annually, growing at about 10% per year Financially Strong and Stable National fueling operations managed from Salt Lake City, with major operational hubs in Los Angeles, Orange County, San Diego and New York City

3 Outline Station design and performance considerations Understanding design and performance requirements Spec for flexibility Getting an apples-to-apples comparison Station ownership and management options Own, operate and maintain Own with contract maintenance Lease Public access option Commodity options Gas procurement methods

4 CNG Station Design and Performance Considerations Operational requirements Fleet consumption and refueling requirements Fast fill vs. Time fill Redundancy Critical nature of operation Backup supply availability Energy and operational efficiency Utility Rates Labor Security and remote monitoring System surveillance 24/7 Security cameras and DVR

5 CNG System Components Fast Fill Basic Fast Fill Station w/ Redundancy 50 DGE in 10 minutes Fast Fill System Components Two compressors Redundancy Gas Dryer Trillium Controls CNG Storage One Twin Hose Fast Fill Dispenser Trillium Sequencing Valve Panel Electrical Gear 24/7 Remote Station Monitoring

6 CNG System Layout Fast Fill Fast Fill Site Conceptual Layout

7 CNG System Components Time Fill Basic Time fill station w/o redundancy DGE = 1,000 DGE in 9 hours Time Fill System Components One compressor No redundancy Gas Dryer Trillium Controls CNG Storage, one (1) sphere total of 10,000 SCF 20 time fill post 1 fast fill post (optional), not metered Trillium Valve Panel Electrical Gear 24/7 Remote Station Monitoring

8 CNG System Layout Time Fill Time Fill Site- Conceptual Layout

12 Web Based Innovations Trillium Real time 24/7 video accessible via the internet; DVD video storage

13 Web Based Innovations Real time 24/7 web based monitoring of your CNG station which can be viewed by the customer from any computer with internet access

14 Station RFP & Spec Considerations RFPs which allow for flexibility can yield better results Performance based specs vs. equipment based specs Using resources to develop options RFP and Project Timing Start early for the best results Identify critical path issues early on Plan for the future Construction Utility requirements Private vs. Public Access Tradeoffs

17 CNG System Layout Time Fill Growth Considerations Additional Pad Additional Storage Electrical Requirements Future Growth Projections

19 Station RFP & Spec Considerations Utilities matter Gas supply pressure Electricity requirements Distance to run utilities Permitting Local agencies Utility runs and Rights-of-Way Maintenance facility requirements NFPA 52 guidance Vary with jurisdiction

22 Facility Maintenance Upgrades General requirements for CNG maintenance garages: Ventilation of at least four (4) air changes per hour Roof designed for ventilation Electrical Class 1 Division 1 within 18" of ceiling Methane Detection system Requirements from Authorities Having Jurisdiction (Fire Department)

23 Ensuring an Apples-to-Apples Comparison Between Proposals Proposals from vendors will vary in scope and cost for the same project Generally attempting to be responsive Provide maximum value as it supports their case Take the time to evaluate the offering in detail Use a detailed checklist compare head-to-head Results of your efforts can be telling Some things to look for: Sales tax, utility runs, transformers, dispensers and fill posts, tax credit disposition, etc.. Process will likely require clarification or an additional round of proposals

25 CNG Project Checklist - Example Equipment and Installation Trillium Other Number of compressors 1 Horsepower of each compressor 75 SCFM of each Compressor 120 Total SCFM of system 120 Suction Pressure Required Gas detection on skid Yes No Yes No Sound attenuated enclosure Yes No Yes No Number of storage vessels / Total Capacity 0 SCF SCF Number of dispensers Fast-fill single hose Fast-fill twin hose Time-fill single hose Time-fill twin hose 5 psi Five posts, ten hoses total Fuel management system Yes No Yes No Size of emergency power generator None Is all of the proposed equipment new? Yes No Yes No Does the equipment pricing include sales tax? Is the $50,000 Federal tax credit for fueling infrastructure accounted for? Yes No Yes No Yes No Yes No Utilities Trillium Other How many feet of conduit, conductors and trenching are included to bring electrical service to the switchgear and compressor equipment? 25 ft Utilities, continued Trillium Other Are the following electrical system components included: Distribution gear for CNG station Yes No Yes No Disconnect and soft start for each motor over 25 hp Yes No Yes No Main disconnect for CNG station Yes No Yes No New transformer Yes No No No Transformer vault Yes No No No Transformer pad Yes No No No Operations and Maintenance Trillium Other What is the response time for emergency call outs? Is 24/7 remote station monitoring included? Can the station status be viewed over the internet? Is disposal of hazardous materials generated during the operation of the station included? How many feet of welded pipe and trenching are included to bring gas from the gas utility meter to the compressor area? What amperage is required for the CNG station? 25 ft 200 amps Is there a minimum fuel purchase required? If yes, what volume per month? If the Federal Excise tax credit of $0.50 per GGE is reinstated, who will receive it?

27 Cost Components of CNG Stations Cost Component Description Units Station Capex Capital cost of design and build for CNG station Monthly or in $/fuel unit Gas Commodity Natural gas purchased from gas utility or gas marketer (1) $/Therm or $/MMBTU Transportation Distribution Charges Taxes Compression Station Operations and Maintenance (O&M) Pipeline transportation to utility s city gate (1) ; Other state fees can appear here Local gas distribution company (LDC or utility) charge (2) Federal/state/local gross receipts/use taxes and/or special assessments Compressor drive motor (gas/electric) Preventative maintenance, scheduled repair, and rebuilds $/Therm or $/MMBTU $/Therm or $/MMBTU $/DGE or $/GGE $/kwh or $/MMBTU $/Therm, $/DGE or $/GGE (1) Gas purchases from marketers - commodity and transportation - are billed separately from utility distribution charges (2) Distribution charge subject to change by the CPUC and the local utility, generally every three to five years
