1 Fueling Phoenix s Past, Present & Future APWA Sustainability Conference May 14, 2013 Joe Giudice, Deputy Public Works Director City of Phoenix

2 About the City of Phoenix 6 th largest city in U.S. Largest city with council-manger form Water use, air quality, land use planning major sustainability challenges AAA bond rating The city takes up more than 500 square miles, geographically exceeding Los Angeles.

3 City of Phoenix Fleet Sustainability Commitment of Leadership Top 10 Green Fleet Ranking #5 in 2012 Valley of the Sun Clean Cities Coalition Sustainable Fleet Policy Energy Security Protect Air Quality Diversity of Fuel/Price Volatility The Phoenix Way

4 Portfolio of Alternative Fuels

5 Why Alternative Fuels Regional Air Quality Law and Politics Managed Competition Energy Security National Trend

6 Regional Air Quality South Mountain 8/2/12 this is a green day

7 Pounds of CO2 CO2 Reduced over 5 Years Pounds of CO2 Reduced Over Last 5 Years 1,800,000,000 1,600,000,000 Without Alternative Fuel Use Without Alternative Fuel Use With Alternative Fuel Use 1,400,000,000 1,200,000,000 1,000,000,000 } 75 Million Pounds of CO2 With Alternative Fuel Use 800,000, ,000, ,000, ,000,000 0

8 Alternative Fuel Vehicle Law & Politics Local government must develop and implement vehicle fleet plans At least 75% of the total local government fleet must operate on alternative fuel (Reference Arizona Revised Statutes , , , and ) Energy Security

11 National Trends At our current rate of conversion, we plan to have more than 3,100 trucks on natural gas and other alternative fuels by the end of 2015 (source: Republic Services website) Waste Management will announce it is pushing forward on a nationwide plan to convert all of its 18,342 trucks from loud and smoky diesel engines to quieter and cleaner compressed natural gas-powered machines.

18 Fueling the Future Sustainable Fleet Strategy Future Energy Portfolio 50% Target 2-3 years 100% Target by 2020 Managed competition require alternative fuel use Sky Harbor Airport Phoenix Transit System

19 What is Natural Gas Primarily methane accounts for 25% of US energy 80-90% domestically produced Renewable natural gas Gas at standard temp/pressure Abundant domestic reserves CNG vs. LNG

20 Cleaner Burning Fuel Carbon Reduction: Diesel creates 22.4 lbs of carbon for each gallon burned vs. Natural Gas that creates 15.1 lbs of carbon for each gallon burned. An average garbage truck burns 40 gallons of fuel per day/10,560 gallons per year. Switching to Natural Gas can reduce carbon footprint by 77,088 lbs per truck annually. According to America s Natural Gas Alliance ONE CNG refuse truck = taking 325 cars off the road

21 Phoenix Solid Waste Program 550 Square Miles 398,000 Residential Customers 4+ Million Miles 4 Service Centers 286 Slow Fill stations

22 Fuel Cost Savings: CNG vs. Diesel Each new truck is projected to travel approximately 1,227 miles per month CNG (DGE) Diesel Miles Per Gallon Fuel Needed Per Month Approximate Fuel Cost $1.50 $3.60 Monthly Fuel Cost $ $1, Monthly fuel savings with CNG - $ Per Truck Annual fuel savings of $13,885 Per Truck Annual fuel savings for a 286 truck fleet: $3.9M

23 Moving Towards a CNG Fleet Diesel to CNG Transition % 100% 89% 90% 92% 94% 80% 60% 49% 73% Percentge of CNG Percentage of Diesel 40% 32% 20% 0% 3% 18%

24 Paradigm Shift of Fuel Program Fuel Infrastructure Fuel Metering Slow fill vs. Fast fill Shop Infrastructure Compressor considerations

25 Paradigm Shift of Fuel Program Fuel supply (emergency) Evacuation System Maintenance support / costs Driver time spent fueling (slow-fill) Tank Issues No exhaust after-treatment system
