Port Washington
Location: WI
Operator: Wisconsin Electric Power Co
Configuration: 5 X 80 MW
Operation: 1935-1950
Fuel: bituminous coal
Boiler supplier: CE
T/G supplier: AC
Quick facts: When more power was needed in the southern Wisconsin area, a new site at Port Washington north of Milwaukee was selected for a large power station. This location took advantage of lake boat coal delivery, good rail connections and ample cooling water. Construction for the Milwaukee Electric Railway and Light Co began in 1930 and the first unit generated electricity on 14 Oct 1935. It cost $7.5mn and is shown in the photo above. Port Washington had the world's largest high-pressure boiler yet built, and introduced the use of 1,200 PSI steam and 825F turbine throttle temperatures. It was the world's most efficient power station from 1935-1948. Port Washington is an ASME National Historic Mechanical Engineering Landmark.
