Dickerson Generating Station
The Dickerson Generating Station is an 853 MW electric generating plant owned by NRG Energy, located approximately two miles west of Dickerson, Maryland. Description The facility consists of three 182 MW coal-fired steam generating plants, two 147 MW gas and oil-fired simple cycle combustion turbines, and one 13 MW black start and peaking turbine. The three coal-fired units are base-loaded and went into operation in 1959, 1960, and 1962 respectively. Condenser cooling for these units is accomplished with once-through cooling water from the Potomac River at a rate of up to per day. Coal is delivered to the Dickerson Generating Station by CSX Transportation train. The two combustion turbines are General Electric Frame 7F gas turbines which went into operation in 1992 and 1993, and are normally fired with natural gas from a Consolidated Natural Gas company pipeline which traverses the Dickerson site.

Corporate Spin-off
A corporate spin-off, also known as a spin-out, or starburst or hive-off, is a type of corporate action where a company "splits off" a section as a separate business or creates a second incarnation, even if the first is still active. Characteristics Spin-offs are divisions of companies or organizations that then become independent businesses with assets, employees, intellectual property, technology, or existing products that are taken from the parent company. Shareholders of the parent company receive equivalent shares in the new company in order to compensate for the loss of equity in the original stocks. However, shareholders may then buy and sell stocks from either company independently; this potentially makes investment in the companies more attractive, as potential share purchasers can invest narrowly in the portion of the business they think will have the most growth. In contrast, divestment can also sever one business from another, but the assets are sold off rather ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maryland Electric Deregulation
Maryland Electric Deregulation is the result of a bill passed in 1999 by the Maryland General Assembly. This bill changed the entire face of the Maryland utility industry. In 1999, the Maryland General Assembly, under pressure from state manufacturers, enacted legislation that would cause the electric industry in Maryland to become deregulated. This bill, the Electric Customer Choice and Competition Act of 1999, was passed through the Maryland General Assembly with many Democratic and every Republican legislator's support. The bill was signed into law by Democratic Governor Parris Glendening who was not in favor of deregulation, but was threatened with an override if he opted to veto. Prior to this legislation, the local electric utility was in charge of procuring and delivering power to the people in their service territory. Under the new legislation, the consumer could choose to continue purchasing power from the local utility (known as Standard Offer Service (SOS) or Provider of ...

Monocacy Aqueduct
The Monocacy Aqueduct — or C&O Canal Aqueduct No. 2 — is the largest aqueduct on the Chesapeake and Ohio Canal, crossing the Monocacy River just before it empties into the Potomac River in Frederick County, Maryland, USA. The 438 foot (133.5 m) aqueduct was built by three separate contractors between 1829 and 1833 at a cost of US$127,900. Description The aqueduct is a stone masonry structure with a waterway of 19 feet at the bottom and 20 feet at the top. The towpath parapet wall is 8 feet wide and the upstream wall is 6 feet wide.

Chesapeake And Ohio Canal
The Chesapeake and Ohio Canal, abbreviated as the C&O Canal and occasionally called the "Grand Old Ditch," operated from 1831 until 1924 along the Potomac River between Washington, D.C. and Cumberland, Maryland. It replaced the Potomac Canal, which shut down completely in 1828, and could operate during months in which the water level was too low for the former canal. The canal's principal cargo was coal from the Allegheny Mountains. Construction on the canal began in 1828 and ended in 1850 with the completion of a stretch to Cumberland, although the Baltimore and Ohio Railroad had already reached Cumberland in 1842. Rising and falling over an elevation change of , it required the construction of 74 canal locks, 11 aqueducts to cross major streams, more than 240 culverts to cross smaller streams, and the Paw Paw Tunnel. A planned section to the Ohio River at Pittsburgh was never built. The canalway is now maintained as the Chesapeake and Ohio Canal National Historical Par ...

Chesapeake And Ohio Canal National Historical Park
The Chesapeake and Ohio Canal National Historical Park is located in the District of Columbia and the state of Maryland. The park was established in 1961 as a National Monument by President Dwight D.

The Chesapeake and Ohio Canal Construction on the Chesapeake and Ohio Canal (also known as "the Grand Old Ditch" or the "C&O Canal") began in 1828 and ended in 1850 when the canal reached Cumberland, far short of its intended destination of Pittsburgh, Pennsylvania. Occasionally there was talk of extending the 184.5-mile canal: for example, an 1874 proposal to dig an 8.4-mile tunnel through the Allegheny Mountains, and there was a tunnel built to connect w ...
