Provisions for re-energizing the electric system of the Consolidated Edison Company of New York, Inc.

IN the course of the last three or four years there have been a few instances in which generating stations supplying electric service in large metropolitan systems have shut down temporarily because of storms and floods of unusual severity or because of accidents resulting in fires which could not be quickly brought under control. These occurrences, while fortunately very infrequent, have focussed attention upon the problem of starting up a large system in the event of a complete shutdown of one or more generating stations supplying it. It is therefore the purpose of this paper to present: 1. Some of the more important considerations affecting the design of the distribution system and the generating stations in the Consolidated Edison system with respect to the ability to restore service after a complete shutdown. 2. The principal features of the operations involved in re-energizing the electric system, in accordance with a predetermined plan. 3. A review of some operating experiences related to the problem of re-energizing the system.
