Discover the history of the Folsom Powerhouse, California Historical Landmark 633, where the first long-distance transmission of high-voltage alternating current began.

The Folsom Powerhouse represents the birthplace of the modern electrical grid, proving for the first time that we could harness the raw power of a river and deliver it to a distant city with nearly perfect efficiency.
The history and significance of California Historical Landmark No. 633 (historic Folsom powerhouse) and its relationship to the surrounding state park, including how to explain the difference between its landmark status and state park designation to visitors.







The Folsom Powerhouse is recognized as California Historical Landmark No. 633 and is considered the birthplace of the modern electrical grid. In 1895, it achieved a technological miracle by transmitting high-voltage alternating current over twenty-two miles to Sacramento. This historic site demonstrated that the raw power of a river could be harnessed and delivered to a distant population center with nearly perfect efficiency, changing how the world uses electricity.
The Grand Electric Carnival was a massive celebration held in Sacramento in September 1895 to mark the successful transmission of power from Folsom. During the event, thousands of incandescent bulbs illuminated the State Capitol and downtown streets, showcasing the potential of long-distance electricity. It served as a victory lap for the technological advances in hydroelectric power and alternating current that allowed a major city to be powered from miles away.
The experiments conducted at the Folsom Powerhouse proved that high-voltage alternating current could be transmitted over long distances to power major cities. This momentous advance in science and engineering laid the foundation for the modern electrical grid we use today. Every time you flip a light switch or plug in a laptop, you are a direct beneficiary of the hydroelectric power innovations and transmission techniques first perfected at this historic California site.
