equipment, and installation at a site with the specified assumptions. The
estimates do not include costs associated with unusually complicated
installations, difficult permitting issues, compressor redundancy, or similar
factors that could increase the total project cost.
Unless otherwise noted, the estimates for fast-fill stations assume a
vehicle fueling window in which 70% of the fuel is dispensed during two
hours in the morning and two hours in the afternoon. For time-fill stations, the
compressor is assumed to run for 10 hours per day. Fast-fill cost estimates for
the small, medium, and large stations include a priority panel and credit card
reader. All scenarios include a gas dryer.
It is important to note that the cost of a CNG station may vary
substantially from the estimates listed here. Contact a CNG equipment
supplier or engineer who specializes in CNG station design to determine the
appropriate design and cost for a specific application.
