On March 13, 1889, Avista, formerly known as Washington Water Power, was incorporated eight months before the Washington Territory became a state. Today, the company is one of only three companies remaining in the state that are classified as Territorial Corporations – incorporated before Washington’s statehood. The company began on the banks of the Spokane River with the Monroe Street plant, using hydropower to generate electricity for the growing city of Spokane Falls. Today, clean, renewable resources remain a significant part of the company’s diversified mix for energy generation.
