Location: IL
Operator: Midwest Generation LLC
Configuration: 2 X 554 MW, 3  X 530 MW
Operation: 1977-1979 (ret 2004)
Fuel: natural gas, fuel oil
Boiler supplier: B&W
T/G supplier: GE, WH, MAN, Alsthom
Quick facts: Collins was the largest oil-fired, steam-electric plant ever built in the USA. It was one of seven plants acquired in Dec 1999 by Midwest Generation from Commonwealth Edison for $4.8bn. The plant was originally designed to back-up Commonwealth's nuclear and coal-fired power plants, but only ran sparingly. It was converted from oil-only to dual-fuel capability from 1992-1997 and finally closed in 2004.

Georgetown Steam
Location: WA
Operator: Seattle Electric Co
Configuration: 1 X 3 MW, 1 X 8 MW, 1 X 10 MW
Operation: 1906-1917 (ret)
Fuel: fuel oil, coal
Boiler supplier: B&W
T/G supplier: GE
EPC: Stone & Webster
Quick facts: In 1980, this facility on the Duwamish River was designated as an ASME National Lanmark. In part, this is due to the installadtion of three Curtis turbines, manufactured by GE from 1906 and 1917. The design of the Curtis turbines established the steam turbine as a practical and compact prime mover and the Georgetown plant is said to have the only two survining Curtis turbines in essentially operable condition. This is also one of the first reinforced concrete buildings built on the West Coast and was designed by Frank Gilbreth. The plant supplied power to the Seattle-to-Tacoma Interurban and Seattle streetcars as well as to customers in Seattle's Georgetown district. The Georgetown plant ran on oil for 9yrs, was converted to coal, and returned to oil firing in the 1940s, although it was barely running by that time. The power plant was taken over by Seattle CIty Light in 1951 and last run for load from Nov 1952-Jan 1953 during a regional shortage of hydropower. It has in part been restored to conduct tours and to host other activities.

Lake Union
Location: WA
Operator: Seattle City Light
Configuration: 1 X 7 MW, 1 X 10 MW, 1 X 13 MW
Operation: 1914-1921 (ret)
Fuel: oil
Boiler supplier: Stirling
T/G supplier: AC
Quick facts: This photo was taken in June 1917 and shows Hydro House on the left and the Lake Union steam plant on the right. Daniel Riggs Huntington, later City Architect, was the designer. The steam plant was finally closed in 1987 and was purchased in 1993 by ZymoGenetics for use as its corporate HQ. During renovation, seven decaying smokestacks were replaced with six smaller facsimiles. The purchase price for the Lake Union Steam Plant was $1.6mn and something over $20mn was spent on environmental remediation and other work.

Location: ND
Operator: Ormat Technologies
Configuration: 1 X 5.5 MW
Operation: 2006
Fuel: ORC - waste heat
T/G supplier: Ormat
EPC: Wanzek Construction
Quick facts: This plant went commercial in Jan 2009. It is one of eight ORC plants built and operated by Ormat at natural gas compressor stations along the Northern Border Pipeline and selling power to Basin Electric Power Coop. The exhaust from 39,000HP compressors on the pipeline is about 900° F and is passed to two series of heat exchangers with different working fluids in an organic Rankine cycle and finally to a turbine generating electricity. The facilities are baseloaded and treated as renewable generation for the Basin system.
