CCRTA’s 2012 CNG Project
Bus Fleet Mix Fixed Route Buses - 81 30 ft – 17 35 ft – 41 (5 New CNG) 40 ft – 16 (5 New CNG) Trolleys - 7 Current Fuel Type – Diesel and CNG Premium for CNG bus - $25,000 (Gillig)
Paratransit Fleet Mix Current Paratransit Fleet – 34 (unleaded fuel) On Order – 23 ARBOC CNG Paratransit Vehicles (replacement vehicles) Premium for CNG paratransit - $25,000
Support Vehicle Fleet Mix Support Vehicles – 30 (unleaded); 7 (CNG) MV 1’s (CNG), pick up trucks, relief cars Premium for CNG vehicle - $10,000
Making the Case for CNG in 2011 – Annual Fuel Price Estimate for Buses Annual Fuel Price Comparison for Buses Diesel vs. CNG Usage Diesel Fuel Buses – 807,000 diesel gallons x $3.17 = $2,558,190 CNG Fuel Buses – 807,000 x 1.18 (DGE rate) =952,260 DGE x $0.92 CNG average rate = $876,079
Total estimated bus fuel annual savings generated by using CNG fuel - $1,682,111 (if a 100% of bus fleet was CNG)
CNG Fuel Savings in 2013 and 2014 • CNG Bus - $1,600 monthly savings X 12 mos. = $19,200 annual projected savings per bus • Total annual 2013 savings for 10 buses $230,400 • CNG Paratransit Vehicle - $838 projected monthly savings per vehicle • Total projected savings for 23 Paratransit vehicles put in service in December 2013 $19,274 • Projected CNG Paratransit Savings for 2014 $231,288.

What is the Payback Based on 2013 Data?
CNG Implementation Costs: Current projected premium for fleet $2,875,000 CNG Shop Modifications and Fueling Station $5,000,000 Total costs of implementing CNG $7,875,000 Payback period would take approximately 5 years if fleet was 100% CNG today ($7,875,000 divided by projected $1,555,200 bus annual savings = 5 years) Actual payback period will take approximately 8 years (2019) based on current bus replacement schedule.
