Chusaimen Power Plant is the first generation of Taiwanese power plants, and is currently the only power plant built in the 1900s that remains operational. The plant was part of the infrastructure crucial to southern modernization. Its main building is simple and elegant, with a circular arch exterior. A steel roof frame forms a double-pitch roof with a covered ridge and sidewall opening ventilation system at the top. Chusaimen Power Plant is home to antique-grade generators, as well as attractively placed large water-conducting steel pipes at the rear of the building.
