The paper gives some general statistics on plate-glass manufacture, and estimates that the present total electrical requirements of the industry in the United States, are about 350,000,000 kw-hr. per annum. About 60 per cent of this energy is purchased and is considered a very desirable load from the central station point of view, as the plants generally run almost continuously and shut down only a short time on Sundays, giving a very desirable load factor. The paper briefly describes the manufacturing processes, and shows the different operations requiring the application of power. Specifically, it describes the 110-kv. station built for the Crystal City plant. This is designed along very simple lines to take the place of an isolated plant.
