This increased its production efficiency and volume, and required the addition of more buildings — a boiler house, oil and coal storage and more gasholders. The following year the company merged with the American Illuminating Company to become the Saratoga Gas, Electric Light and Power Company. A dynamo on the site provided electricity for the city's street lights. In 1903 the electricity-generation facilities were further expanded. The substation, a steam boiler and smokestack were added. Power generation continued for eight years, until 1911, when yet another merger created the Hudson River Water Power Company. It built a regional power distribution system to carry the power generated by its dams all over the southern Adirondack region. With the cheaper hydroelectric power available, and industrial customers willing to use it in large quantities, it was no longer economical to generate power in Saratoga Springs. 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. The property underwent environmental cleanup ordered in 1995. The gasholder was originally slated for demolition but was eventually moved intact to its present location at the northwest corner of the site.
