The Chalk Point Generating Station is a 2,647-MWe electricity-generating plant owned by GenOn (formerly Mirant) which is located near the tiny incorporated town of Eagle Harbor, Maryland, United States, on the Patuxent River.

Individual Units

The facility consists of several units:

Units ST1 and ST2 are coal-fired dry-bottom, wall-fired steam generating plants rated at 364 MWe each. They were put into service in 1964 and 1965.
Units 3 and 4 are oil and natural gas fired units rated at 659 MWe each, put into service in 1975 and 1981. These units are cooled by natural-draft cooling towers.

The site also contains six combustion turbines owned and operated by Mirant.

Oil-fired units GT1 and GT2 (put into service in 1967 and 1974) are rated at 16 MWe and 35 MWe.
Oil/gas-fired units GT3–GT6 (put into service in 1991) are rated at 103, 103, 125, and 125 MWe respectively.
A seventh oil/gas-fired combustion turbine, unit SGT1, is rated at 94 MWe (put into service in 1990). It is owned by the Southern Maryland Electric Cooperative (SMECO). This turbine is operated by Mirant under an agreement which expires in 2015.[1]

The combined name-plate capacity of all seven combustion turbines is 601 MWe.[2] [3]

History

The Chalk Point plant began service in 1964.[4] All of the GenOn generating units at the Chalk Point Generating Station were built by the Potomac Electric Power Company, which sold them to the Southern Company in December 2000 as a result of the restructuring of the electricity generating industry in Maryland. The station was included in the Mirant spin-off from the Southern Company in April 2001. Mirant was merged into GenOn Energy in 2010.[5]

Fuel delivery

Coal is delivered to the Chalk Point generating station by CSX Transportation trains via the Herbert Subdivision, a former Pennsylvania Railroad (PRR) line. This line is accessed via the Amtrak Northeast Corridor line, with coal being delivered from trains staged at the CSX Benning Yard (also former PRR facilities) in Anacostia, Washington, DC. These trains are brought from the coal fields via the CSX Metropolitan Subdivision and Cumberland Subdivision down the Potomac River valley from Cumberland, Maryland.

Dispatch of electricity

The electrical output of Chalk Point Generating Station is dispatched by the PJM Interconnection regional transmission organization.[4]

Environment

Chalk Point plant is by far the leading polluter in Prince George's County, Maryland, according to pollution research site Scorecard.org.[6] It produced 5,271,800 pounds (2,391 metric tons) of air pollution (not counting CO2) and 3,702 pounds (1.7 metric tons) of water pollution in 2002. (The second largest polluter, the USDA's Henry A. Wallace Beltsville Agricultural Research Center, produced 79,550 pounds (36 metric tons) of mostly land pollution in 2002.)
