Niagara Frontier Transportation Authority required a scalable fueling system to adapt to their growing fleet while reducing initial capital cost. A solution was designed to give them the capability to more than double the capacity of the station in the future. The current station has the ability to simultaneously fast fuel any combination of up to four buses either 40 foot heavy transit buses or cutaway vans in a semi-sheltered canopy.

Buffer fast fill stations are designed to provide high speed fueling during extended fueling shifts that might last for several hours. The storage buffer itself is intended only to allow the compressors to continue to run loaded as buses are connected and disconnected. Buffer fast fill stations tend to include the largest and most complex equipment of all fill station configurations but provide the ability to dispense a large amount of fuel over an extended total fill shift.
