16. NATURAL GAS vs. ELECTRIC The Big Picture – Direct Use is Most Efficient… ….so, distributed generation at the home makes sense.

17. Combined Heat and Power (CHP) is more Efficient 17 http://www.aga.org/our-issues/playbook/Documents/AGA_Playbook2012_HI_RES.pdf

18. 18 Executive Order – August 30 “Coordinate and strongly encourage efforts to achieve a national goal of deploying 40 gigawatts of new, cost effective industrial CHP in the United States by the end of 2020.” ”Convene stakeholders, through a series of public workshops, to develop and encourage the use of best practice State policies and investment models that address the multiple barriers to investment in industrial energy efficiency and CHP.” ”Utilize their respective relevant authorities and resources to encourage investment in industrial energy efficiency and CHP.”

19. Federal Support for CHP 19 Incentives 10% Investment Tax Credit (ITC) for CHP through December, 2016; 50 MW or less 10% ITC for micro turbines capped at $200/kW of capacity; 2 MW or less 30% ITC for fuel cells or $3,000/kW ($1,000/ kW residential), whichever is smaller Modified Accelerated Cost-Recovery System – for 2013 bonus depreciation is 50% of the eligible basis Renewable Energy Production Tax Credit (ARRA portion expires end of 2013) – renewable fuels only Support EPA recognizes CHP as an efficiency measure under developing greenhouse gas emissions standards EPA includes output-based options that recognize CHP benefits in ICI Boiler MACT and Utility MACT (MATS) DOE increases technology deployment support for CHP and announces goal of 40 GW of new CHP capacity by 2020 Clean Energy Standard Act of 2012 – Includes nuclear, clean coal, and natural gas – Recognizes the additional energy efficiency and greenhouse gas benefits of CHP Proposals to encourage rate-basing of utility investments in behind the meter energy efficiency and CHP Florida - Renewable energy tax credit of 1¢/kWh annually (CHP is eligible), Solar and CHP sales tax exemption. Net metering excess generation credited at the utility retail rate.

21. The U.S. is the world’s largest natural gas producer, but lags behind other nations in natural gas transportation There are more than 12.7 million natural gas vehicles on the road worldwide – but less than 125,000 are in the United States. Source: NGV Global

22. Fuel price is the driver, and it is expected to stay this time….

23. PRICING CHARACTERISTICS 20% 13% 27% 40% Natural Gas Distribution & Compression Marketing & Profit Taxes CNG (July 2012) Retail Price: $1.85/gge The natural gas commodity cost component is about one quarter the crude oil cost component in the make-up of the overall price of the delivered fuel, giving CNG a price dampener against price volatility.

24. PRICE STABILITY OF CNG Natural Gas at $2.88/Mcf Natural Gas (divide by 7.2) $0.40 Transport Costs & Fees $0.20 Electricity Costs per GGE $0.10 Maintenance per GGE $0.20 Federal and State Taxes $0.25 Fuel Card Fees per GGE $0.05 Retailer Profit Margin $0.70 CNG at the Pump $1.90 Natural Gas at $5.76/Mcf Natural Gas (divide by 7.2) $0.80 Transport Costs & Fees $0.20 Electricity Costs per GGE $0.10 Maintenance per GGE $0.20 Federal and State Taxes $0.25 Fuel Card Fees per GGE $0.05 Retailer Profit Margin $0.70 CNG at the Pump $2.30 The natural gas fuel commodity makes up a smaller portion of the overall price of the delivered fuel when compared to gasoline or diesel.

26. THE LIGHT DUTY MARKET CHALLENGE $500,000+ for Centralized Fueling Stations 500 down, 160,000 to go - $50+ billion? in investment to match gasoline stations The economics work for fleets, so there will continue to be growth $100,000?+ to make a private station public accessible $8,000+ Vehicle Conversion/Replacement Premium Takes 7 years+ to recover the premium Limited vehicle selection from OEM’s, especially vehicles desired by target customers Efforts around conversion, and specifically tank technologies, is ongoing $5,000 Home Refueling Appliance (HRA) product and Installation Cost An additional 4+ years to recover the HRA cost Limited fill capability, maintenance unknown (historically not good) Result: $8,000 + $5,000 = $13,000 per vehicle premium, or 11+ years payback MUST REDUCE VEHICLE CONVERSION COSTS & DEVELOP A LESS EXPENSIVE HRA

27. Expect 12% of New vehicle sales to be NGV’s by 2020 NGV Engine Costs are expected to be competitive by 2020

28. THE HOME REFUELING APPLIANCE (HRA) BRC Fuelmaker Phill is the only commercially available HRA Expensive price with installation, approximately $6,000 Limited fill capability, less than a half gallon per hour Historically has had compressor performance and maintenance issues AGL is a distributor, and installs and maintains Phill units AGL Resources is actively engaged with a team of industry leaders in the development of a less costly HRA U.S. Department of Energy - Advanced Research Projects Agency-ENERGY (ARPA-E) – Methane Opportunities for Vehicular Energy (MOVE) 13 projects awarded with $30 million in funding – including 4 HRA designs Engineer Light-Weight Affordable Natural Gas Tanks Develop Natural Gas Compressors that can efficiently fuel a NGV at home GTI and GE have projects within this program, and AGL is actively involved

29. Florida Legislation is headed in the right direction Repeals the “Decal” program for Alternative Fuels effective January 1, 2014 Exempts natural gas fuel from taxes for 5 years Survey of Florida residents shows 72% support for legislation encouraging NGV adoption 96% of the residents think Energy Independence is important Florida Natural Gas Vehicle Coalition In an August 2012 study, the transistioning of Florida Commercial Fleets to Natural Gas results in following benefits over 20 years: 10,000 new jobs $330 million in new wages $1 billion in economic output An update based upon February 2013 SB560 and HB579 legislation improves these results as follows over 5 years: 20,000 new jobs $715 million in new wages $2.5 billion in economic output
