Up to three types ofPLANT-EQUIPMENT may be assigned for each load range (seeExample 1).In addition to U-named pieces of PLANT-EQUIPMENT, this maydesignate either a steam, chilled water, or electricUTILITY as an item to meet all or part of the electric;heating, or cooling loads. If any of these options isexercised, the user must further authorize the use ofpurchased steam, cooling, or electricity through theENERGY-COST instruction. The specification of the UNITkeyword in the ENERGY-COST instruction permits the use ofany combination of electric, chilled water, and steamutilities. Since the ENERGY-COST instruction default forUNIT is nonzero for purchased electricity, but zero forpurchased chilled water and steam, the utility automaticallymeets all electric loads not satisfied by on-site generation,but no heating or cooling loads will be met by autility unless UNIT is defined for purchased chilled waterand/or steam.identifies the number of units of the U-named equipmentassigned to meet the load. For example, if two units of asingle-stage machine named ABSOR1 are to be run along witha double-bundle chiller named DBUN1, the followingspecification is required.PLANT-EQUIPMENT = ABSOR1NUMBER = 2PLANT-EQUIPMENT = DBUN1NUMBER = 1If utility steam, chilled water, and/or electricity is tobe used, the user must specify the millions of Btu's ofutility to be supplied.
