About this property

PG&E Powerhouse, also known as Sacramento River Station B is a historic building located in Sacramento, California, constructed in 1912 by notable architect Willis Polk. Originally used by Pacific Gas and Electric PG&E as an auxiliary power plant and transformer substation, it played a key role in transforming voltage for distribution. In 1924, PG&E upgraded the facility, making it the largest steam turbine power plant in the region. However, in 1957, PG&E sold the building, and its interior was stripped of all metal components and equipment, leaving behind a large open space. In November 2021, the building became home to the SMUD Museum of Science and Curiosity (MOSAC) as part of a $40.8 million redevelopment project.
