This invention is a load shaping system which increases the energy efficiency of a compressed air system by eliminating activation of a trim compressor in response to a momentary increase in demand for compressed air. The load shaping system includes a load shaping tank which is supplied by one or more relatively small compressors with compressed air at a pressure higher than that in the main storage reservoir. A computer controlled load shaping valve responds to a decline in air pressure in the main storage reservoir by admitting air from the load shaping tank and by lowering the activation point for the trim compressor. The overall efficiency of the system is increased by avoiding activation of the trim compressor in response to momentary increases in compressed air demand.
