City of Seattle:

Excerpts from the website:
The Georgetown Steam Plant, a surprisingly complete and operable steam power plant after a career of nearly seventy-five years, was built in the early 1900s when Seattle's inexpensive hydroelectric power attracted manufacturers. Much of the power produced at this plant operated the streetcars. It marks the beginning of the end of the reciprocating steam engine's domination in the growing field of electrical energy generation for lighting and power.

The plant's three Curtis turbines, manufactured by the General Electric Company between 1906 and 1917, represent the first two generations of this American innovation. The design of the Curtis turbines established the steam turbine as a practical and compact prime mover, capable of producing large amounts of power. The Curtis steam generator was smaller, had three times the power, and operated more cheaply and smoothly than current-day generators.

Steam meets, free and open to the public, are held on the 2nd Saturday of each month, from 10am until 2pm. Steam meets include operating hot gas, gasoline, air, and steam engines, beverages, snacks, and guided plant tours including oral history and dynamic display of plant engines.
