Agri-chem's contract with enerco specified a maximum of 90,000 cu. ft. x 103 per day for its complexes. however, curtailments are projected to be based on actual usage rather than contractual maximums. the current natural gas usage is 85,680 cu. ft. x 103 per day. enerco projects curtailments in the range of 20 to 40 percent. 1. which of agri-chem's complexes would be least affected by a gas curtailment?
