Coal-Fired Plants in the USA - Maryland
Brandon Shores
Location: MD
Operator: Talen Energy Corp
Configuration: 2 X 685 MW
Operation: 1984-1991
Fuel: bituminous coal
Boiler supplier: B&W
T/G supplier: GE
EPC: Gilbert-Commonwealth, Baltimore Gas & Electric
Quick facts: On 16 May 1973, the Maryland PSC authorized BG&E to construct two 600-MW, heavy-oil fired generating units on a 375ac site along the western shore of the Patapsco River just SE of Baltimore. These were among the last conventional oil-fired units planned in the USA and were initially scheduled for service in 1977/78. Reduced demand caused BG&E to delay the units and government policies necessitated a change to coal-firing, which had been incorporated into the original design. In 1999, SCR systems were added at a cost of $100mn. The boilers also have overfire air systems and low NOx burners. In Jun 2007, selected Washington Group Intl as the EPC contractor for FGD system retrofits. These were commissioned in Dec 2009 along with new baghouses. The FGDs and associated upgrades to the plant wastewater systems cost $1bn with HDR acting as owner's engineer. The original 700ft stacks can be seen from the Chesapeake Bay Bridge, while a new short stack was built for the FGDs. The plant has changed hands several times.

C P Crane
Location: MD
Operator: Talen Energy Corp
Configuration: 1 X 190 MW, 1 X 209 MW
Operation: 1961-1963
Fuel: bituminous coal
Boiler supplier: B&W
T/G supplier: GE, WH
EPC: Gilbert Associates
Quick facts: These two cyclone boilers were retrofit for Nox control with overfire air and gas recirculation systems by General Electric Energy and Environmental Research. The plant also added baghouses from General Electric Environmental Services (formerly Buell). Going forward, Constellation plans to add SNCR and staged-combustion systems for NOx control and switch to subbituminous low-sulfur coal. The site does not have sufficient space available for a full-scale FGD scrubber and SCR retrofit. The plant has changed hands several times.

Dickerson
Location: MD
Operator: NRG Energy
Configuration: 3 X 196 MW
Operation: 1959-1962
Fuel: bituminous coal
Boiler supplier: CE
T/G supplier: GE
EPC: Bechtel, Fluor, Stone & Webster
Quick facts: After an 18mo regulatory review, PEPCO sold Dickerson to Southern Energy (later Mirant) in Dec 2000. The plant was later sold to NRG. In 1992, an artificial, intermediate to advanced whitewater course was built in the discharge canal. This was used by U.S. Olympic Kayak Team to prepare for the Barcelona Olympics. The large stack is 700ft tall. In Dec 2001, Hamon Research-Cottrell was awarded a contract at Dickerson for what was then the largest pulse-jet fabric filter/baghouse installation east of the Mississippi. The equipment replaced existing ESPs and venturi scrubbers. Sargent & Lundy was the A/E for the turnkey job.

H A Wagner
Location: MD
Operator: Talen Energy Corp
Configuration: 1 X 133 MW, 1 X 136 MW, 1 X 190 MW, 1 X 359 MW, 1 X 415 MW
Operation: 1956-1972
Fuel: bitminous coal, fuel oil, natural gas
Boiler supplier: B&W
T/G supplier: GE, WH
EPC: Gilbert Associates, Ebasco
Quick facts: Units 1&4 are gas and oil-firedUnit-3 was retrofit with SCR. INAug 2012, Exelon announced an agreement to sell Brandon Shores, CP Crane and HA Wagner Raven Power Holdings LLC, a portfolio company of Riverstone Holdings LLC, for about $400mn. The sale was required by the FERC, the US DOJ, and the Maryland PSC as part of Exelon’s merger agreement with Constellation Energy. The sale closed Dec 2012.

Morgantown
Location: MD
Operator: NRG Energy
Configuration: 2 X 626 MW
Operation: 1970-1971
Fuel: bituminous coal, oil
Boiler supplier: CE
T/G supplier: WH, GE
EPC: Bechtel
Quick facts: After an 18mo regulatory review, PEPCO sold the plant to Southern Energy (later Mirant) in Dec 2000. It is now part of NRG Energy. Morgantown is perennially one of the most efficient conventional power stations in the U.S. and usually has a Top 10 ranking for plant heat rate. Both supercritical boilers were retrofit with low-NOX burners. In Sep 2005, Babcock Power Inc and Zachry Construction were contracted to design, supply and erect SCR systems for Morgantown. B&W FGD scrubbers are being added by Shaw Group. The twin 700ft stacks are local landmarks.

R Paul Smith
Location: MD
Operator: Potomac Edison Co
Configuration: 1 X 15 MW, 1 X 28 MW, 1 X 35 MW, 1 X 87 MW
Operation: 1927-1957 (ret)
Fuel: bituminous coal
Boiler supplier: CE
T/G supplier: GE, AC
Quick facts: The last units at this power station in Williamsport were closed on 1 Sep 2012. The plant was developed and first operated by Potomac Public Service Co, an affiliate of the Hagerstown and Frederick Railway, and later renamed Potomac Edison Co. The site is between the C&O canal and the Potomac River. Construction began in 1922 and the plant was named afte the first preident of Potomac Edison. Potomac Edison was long a part of Alleghency Power which was fully merged into FirstEnergy Corp in Feb 2011.

Warrior Run
Location: MD
Operator: AES Corp
Configuration: 1 X 205 MW CHP
Operation: 2000
Fuel: bituminous coal
Boiler supplier: ABB
T/G supplier: ABB
EPC: Raytheon, ABB
Quick facts: This CFB plant was designed to burn about 650,000 tpy of high-sulfur from a mine 30mi away. The boiler also supplies steam to the adjacent CO2 production unit with an ABB Lummus scrubber system that uses monoethanolamine (MEA) as its solvent. The extracted CO2 is used for food processing and related processes. Emerson Process Management supplied the plant control system. The plant has a 30yr PPA with Allegheny Energy.
