The place

About Folsom Powerhouse State Historic Park

Folsom Powerhouse began operating in July 1895 and transmitted 11,000-volt alternating current about 22 miles to Sacramento, a major early long-distance hydroelectric achievement. The plant operated until 1952 and was later donated by Pacific Gas & Electric for preservation. Original turbines, generators, a marble switchboard and related canal and forebay infrastructure interpret the system.

The live State Parks page lists the Visitor Center Wednesday noon-4 p.m. and Thursday-Sunday 9 a.m.-6 p.m. The Main Powerhouse is listed Wednesday-Friday noon-4 p.m. and Saturday-Sunday 9 a.m.-4 p.m. Use those live hours rather than the separate accessibility page's older Wednesday-Sunday noon-4 block.

The fee module lists $6 hourly parking or $10 vehicle day use and warns rates may change. Dogs are allowed outdoors but not inside the historic buildings. Group and school tours require advance arrangements; do not infer that a guided tour runs throughout every open period.

State accessibility guidance lists accessible parking, a generally accessible powerhouse and a generally accessible unisex restroom. The route from the undeveloped upper lot is steep, automobile drop-off may be arranged, and wheelchair users may need assistance to view the turbine room. Contact the park when slope, drop-off or the complete exhibit route determines the visit.

What stands out

See original generating machinery

Historic turbines, generators and control equipment preserve the mechanics of the 1895 plant.

Trace power to Sacramento

Interpretation follows the 11,000-volt transmission line about 22 miles to California's capital.

Read the marble switchboard

The preserved control system helps connect electrical theory to the operators' daily work.

Connect water and electricity

Canal, forebay and powerhouse features show how the hydroelectric system worked as one landscape.

Pair it with the train

Why it belongs in a Placerville & Sacramento Valley Railroad trip

The Powerhouse ranks first for its direct rail-era infrastructure and electric-technology connection, even though the zoo is slightly closer to the historical Hampton context. It remains independent of P&SVRR, and its parking, hours, access and building rules apply separately whether or not train service has resumed.
