Mohave
Location: NV
Operator: Southern California Edison Co
Configuration: 2 X 790 MW
Operation: 1971 (ret 2005)
Fuel: subbituminous coal
Boiler supplier: CE
T/G supplier: GE
EPC: Bechtel
Quick facts: Mohave was on a 2,500ac site in the Sonora Desert adjacent to the Colorado River in Laughlin, Clark Co. It had supercritical boilers and cross-compound steam turbines. The plant was owned by a utility consortium of operator Southern California Edison Co (56%), LADWP (10%), Nevada Power (14%), and Salt River Project (20%). Mohave was the only power plant in the USA that used coal delivered by coal-slurry pipeline. The 18in diameter Black Mesa Pipeline runs 275mi from Peabody's Black Mesa Mine in Kayenta, AZ, and could deliver 660 tph. Four 8mn gallon storage tanks each held the equivalent of 20,000t of dry coal. The slurry transport water was recycled for cooling tower makeup and this and all other wastewater was recycled and reused making Mohave a zero-discharge facility. The plant was shut in Dec 2005 to comply with a consent agreement reached to settle a 1998 CAA lawsuit brought by several environmental groups. About 300 staff lost their jobs. In May 2007, SCE discontinued efforts to restart or sell the plant. Dismantling got underway in Oct 2009 and is expected to take 2yrs and cost $30mn. Plant demolition began with the toppling of the stack on 11 Mar 2011.

Mount Poso
Location: CA
Operator: Northern Star Generation LLC
Configuration: 1 X 62 MW
Operation: 1989
Fuel: bituminous coal, petroleum coke, TDF
Boiler supplier: Foster Wheeler
T/G supplier: GEC-Alstom
EPC: Bechtel
Quick facts: This cogeneration plant was originally built by Mt Poso Cogeneration Co, a joint venture of Ahlstrom Development Corp, Pacific Generation Co, and Bechtel Enterprises. The facility provides steam for enhanced oil recovery at the Mt. Poso Field-West and was originally built as a baseload cogen plant under PURPA but deregulation in California starting in 1998 moved it to a cycling merchant-plant business model.

Stockton Cogen
Location: CA Operator: Ace Products & Chemicals
Configuration: 1 X 55 MW CHP
Operation: 1988
Fuel: bituminous coal, petroleum coke
Boiler supplier: Pyropower
T/G supplier: ABB
EPC: Stearns Catalytic, Schneider Engineers
Quick facts: On 30 Nov 1984, CPC Internaitonal Inc and PG&E signed a SO4 PPA for capacity and energy from the Stockton CFB cogen plant. CPC later leeasd the property plus all rights and obligations associated with the PPA to Air Products.The PPA expired in 2012 and the plant was closed thereafter.

TS Power
Location: NV
Operator: Newmont Mining Corp
Configuration: 1 X 220 MW
Operation: 2008
Fuel: subbituminous coal
Boiler supplier: B&W Canada
T/G supplier: Toshiba
EPC: Fluor
Quick facts: In Jul 2005, B&W received a contract valued at more than $40mn for the boiler, an SCR, and associated auxiliary equipment. The majority of the pressure parts were fabricated by Babcock & Wilcox Beijing Company, Ltd. The final permit requirements for this plant was issued in Dec 2005. The plant is on the TS Ranch in Eureka county and cost about $630mn. Newmont uses about three-quarters of the output to support its Nevada mining operations with the balance sold to Sierra Pacifc Power. TS Power is operated by DTE Energy.
