Sudden load reduction in a steam power plant

WITH a generating capacity considerably in excess of its local busload, the Sherman Creek generating station of the New York Consolidated Edison Company has to depend on one high-capacity tie to connect it with the rest of the system. Use of the major portion of the plant's capacity, therefore, depends on this tie feeder to transmit all of the plant's output that is not needed for the local bus load. At certain times the plant generates ten times the local load.
