Coal gas
The original gasholder was removed from the first building in 1919. Coal gas production ceased entirely in 1928, and most of the original buildings were demolished in the years afterwards. The substation building remained in use, and the successor utilities also used the area as a storage and maintenance yard until Niagara Mohawk decided it was no longer needed even for those purposes. The utility still owns the land and buildings, and keeps them fenced off.
