Coal-Fired Plants in the USA - Alaska, Hawaii & Washington
AES Hawaii
Location: HI
Operator: AES Corp
Configuration: 1 X 189 MW CHP
Operation: 1992
Fuel: subbituminous coal
Boiler supplier: Pyropower
T/G supplier: Toshiba
EPC: B&V, National Power Development Corp, Pritchard Corp, Hawaiian Dredge & Construction
Quick facts: This cogen plant is the only utility-scale coal-fired PS in the state. The site is in Campbell Industrial Park on the southwest corner of Oahu, 3,000ft north of Barbers Point. To the north is the HPOWER WTE complex. AES Hawaii sells steam to the nearby Chevron refinery and sells electricity to Hawaiian Electric via a 138kV tieline. Construction started in later March 1990 and design fuel is Indonesian subbituminous coal. This is delivered from a marine terminal at Barbers Point Harbo via a 1.6mi conveyor system. The two CFB boilers have can also burn TDF and used actvated carbon from water filtration. . The plant is also known as AES Barbers Point or West Oahu.

Centralia
Location: WA
Operator: TransAlta
Configuration: 2 X 702 MW
Operation: 1972-1973
Fuel: subbituminous coal
Boiler supplier: CE
T/G supplier: Westinghouse
EPC: Bechtel
Quick facts: Centralia was acquired by TransAlta from a consortium of local power companies in 2000. The nearby Centralia mine produced exclusively for the power plant and provides about 85% of the annual 5.5mn ton fuel burn. The balance is sourced form the Powder River Basin. In 2002, TransAlta completed a $180mn plant upgrade including the addition of Alstom FGD scrubbers.

Clear AFS
Location: AK
Operator: US Air Force
Configuration: 3 X 7.5 MW CHP
Operation: 1961
Fuel: subbituminous coal
Boiler supplier: ??
T/G supplier: General Electric
Quick facts: Clear Air Station is home to the 13th Space Warning Squadron whose primary mission is to provide early warning of ballistic missiles launches to North American Aerospace Defense Command (NORAD). The AFS also provides space surveillance data on orbiting objects. The power plant was retrofit with a baghouse and continuous opacity monitoring system in Aug 2005. Clear AFS burns approximately 58,000 tpy delivered by rail from Usibelli Coal Mine Inc.

Healy-2
Location: AK
Operator: Alaska Industrial Development and Export Authority
Configuration: 1 X 62.9 MW
Operation: 2015
Fuel: subbituminous coal
Boiler supplier: FW
T/G supplier: Fuji
EPC: S&W, FW, H C Price Co, Sumitomo
Quick facts: Healy Clean Coal was built after a 1980s DOE solicitation. The advanced slagging combustor boiler has LNB followed by a sorbent injection/spray dryer/baghouse system. In 1991, Golden Valley Electric Assoc entered into a 30yr PPA with AIDEA for output from HCCP. A 90-day test run was completed in Dec 1999, at which time the net capital cost of the facility was $281mn. In Mar 2000 AIDEA and GVEA entered into a Settlement Agreement, which provided for the shutdown of HCCP. This continued until Dec 2009 when GVEA and AIDEA finalized documentation for an asset purchase sales agreement. GVEA purchased the project in 2013 for $44mn and began restart engineering and modifications. Fuel will be from the nearby Usibelli Coal Mine, a project partner from the beginning. Healy-2 was finally cleared for start-up in May 2015.
