1. A method for gauging energy used for producing a unit of mass or volume of compressed gas (Specific Energy Consumption) in relation to a common output flow in a multiple compressor system, said method comprising:
from a first compressor, constructing an ideal specific energy consumption curve in the first compressor as a function of the output flow of the first compressor; and
from the first compressor and a second compressor, constructing a combined ideal specific energy consumption curve in the first compressor and the second compressor as a function of the combined output flow of the first compressor and the second compressor;
constructing one or several ideal specific energy consumption curve(s) for multiple combined compressors, in any combination(s), wherein ideal specific energy consumption curve(s) show the lowest attainable specific energy consumption at a certain pressure level;
creating an operation model for the multiple compressor system, the operation model including at least one ideal specific energy consumption curve(s) for multiple combined compressors, in any combination(s); and
adapting the multiple compressor system based on the operation model.
