In 1899, the Vinita Electric Light, Ice and Power Company, which was headquartered in the Indian Territory town of Vinita (now in Oklahoma) obtained a charter to provide electric power to that community. In 1913, the company consolidated with similar independent companies in Tulsa, Guthrie, Coalgate, Lehigh and Atoka to form a new company, named Public Service Company of Oklahoma (PSO). The founder and first president of PSO was Frederick William "Fred" Insull, who moved the company's headquarters to Tulsa in 1916.
