Casper, WY Natrona Electric Plant Fire, Jan 1918
At about 5 o'clock in the morning January 14, 1918, fire broke out in the plant of the Natrona Electric company and the building and machinery was almost wholly destroyed. Many of the business houses in Casper were heated by this plant and they were without heat or light except that which was furnished by the Wyoming Electric company, who connected the wires and heating plant with their system that same day, but the load was so heavy for this system that the stores and all business houses were ordered not to open before 8 o'clock in the morning and close at 5 o'clock in the evening, and use as little light as possible. The picture shows, churches and lodge rooms were closed, and but one light in each residence in town was allowed to be used. Only the hospitals and newspaper offices were allowed to use the current without restriction. The lighting restrictions were lifted in the business district on February 23, but it was a month later before the residence districts were allowed to use more than one light in each house.
