The Folsom Powerhouse State Historic Park is nestled along the banks of Lake Natoma in Folsom, California. This site offers a captivating glimpse into one of the nation’s first hydroelectric plants. This brick-and-granite marvel, operational since 1895, sparked relentless innovation—transmitting long-distance alternating current power to Sacramento—and today blends industrial heritage with riverside serenity.
What Makes Folsom Powerhouse State Historic Park Unique
The Folsom Powerhouse was designated a National Historic Civil Engineering Landmark. It was also designated a National Historic Mechanical Engineering Landmark. It revolutionized electricity generation and transmission. Four original turbines and General Electric generators still stand, framed by historic canals and forebays. This site remains remarkably intact, offering an authentic window into early electric power, framed by the scenic American River riparian ecosystem.
