Quad Cities Nuclear Generating Station
Quad Cities Generating Station is a two-unit nuclear power plant located near Cordova, Illinois, United States, on the Mississippi River. The two General Electric boiling water reactors give the plant a total gross electric capacity of approximately 1,880 MW. It was named for the nearby cities of Moline, Illinois, Rock Island, Illinois, Davenport, Iowa, East Moline, Illinois, and Bettendorf, Iowa — known as the Quad Cities. The Quad Cities plant is owned and operated by Constellation Energy. In 2004, the U.S. Nuclear Regulatory Commission (NRC) approved a 20-year license extension for both reactors at this plant. Citing the plant's ongoing string of financial losses, Exelon had considered shutting down the facility by 2018. On June 2, 2016, Exelon announced its intentions to close Quad Cities Nuclear Generating Station on June 1, 2018 due to the plant's profitability and a lack of support from the Illinois state legislature. On December 14, 2016, Exelon announced it wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Quad Cities
The Quad Cities is a region of cities (originally four, see History) in the U.S. states of Iowa and Illinois: Davenport and Bettendorf in southeastern Iowa, and Rock Island, Moline and East Moline in northwestern Illinois. These cities are the center of the Quad Cities metropolitan area, which as of 2013 had a population estimate of 383,781 and a Combined Statistical Area (CSA) population of 474,937, making it the 90th-largest CSA in the nation. History Early history Before European settlers came to inhabit the Quad Cities, the confluence of rivers had attracted many varying cultures of indigenous peoples, who used the waterways and riverbanks for their settlements for thousands of years. At the time of European encounter, it was a home and principal trading place of the Sauk and Fox tribes of Native Americans. Saukenuk was the principal village of the Sauk tribe and birthplace of its 19th-century war chief, Black Hawk. In 1832, Sauk chief Keokuk and General Winfield Sco ...

LaSalle County Nuclear Generating Station
LaSalle County Nuclear Generating Station, located in Brookfield Township, LaSalle County, Illinois, near Marseilles, southeast of Ottawa, serves Chicago and Northern Illinois with electricity. The plant is owned and operated by Constellation Energy following separation from Exelon Corporation in 2022. Its Units 1 and 2 began commercial operation in October 1982, and October 1984, respectively. It has two General Electric boiling water reactors. LaSalle's Unit 1 and Unit 2 together produce 2,320 megawatts, which is enough electricity for the needs of 2.3 million American homes. Instead of cooling towers, the station has a man-made cooling lake, which is also a popular fishery — LaSalle Lake State Fish and Wildlife Area — managed by the Illinois Department of Natural Resources.

Braidwood Nuclear Generating Station
Braidwood Generating Station is located in Will County in northeastern Illinois, U.S. The nuclear power plant serves Chicago and northern Illinois with electricity. The plant was originally built by Commonwealth Edison company, and subsequently transferred to Com Ed's parent company, Exelon Corporation. Following Exelon's spin-off of their Generation company, the station was transferred to Constellation Energy. This station has two Westinghouse pressurized water reactors. Unit #1 came online in July 1987. Unit #2 came online in May 1988. The units were licensed by the Nuclear Regulatory Commission to operate until 2026 and 2027, then granted extended licenses until 2046 and 2047. Each unit has received two power uprates during their lifetime, the first in May 2001 for 175.6 MWt and the second in February 2014 for 58.4 MWt. The power uprates at Braidwood granted in 2001 make it the largest nuclear plant in the state, generating a net total of 2,386 megawatts. How ...

Dresden Generating Station
Dresden Generating Station (also known as Dresden Nuclear Power Plant or Dresden Nuclear Power Station) is the first privately financed nuclear power plant built in the United States. Dresden 1 was activated in 1960 and retired in 1978. Operating since 1970 are Dresden units 2 and 3, two General Electric BWR-3 boiling water reactors. Dresden Station is located on a site in Grundy County, Illinois, at the head of the Illinois River, near the city of Morris. It is immediately northeast of the Morris Operation—the only de facto high-level radioactive waste storage site in the United States. It serves Chicago and the northern quarter of the state of Illinois, capable of producing 867 megawatts of electricity from each of its two reactors, enough to power over one million average American homes. In 2004, the Nuclear Regulatory Commission (NRC) renewed the operating licenses for both reactors, extending them from forty years to sixty. Unit 1 After the Atomic Energy ...

Byron Nuclear Generating Station
The Byron Nuclear Generating Station is a nuclear power plant located in Ogle County, Illinois, east of the Rock River. The reactor buildings were constructed by Commonwealth Edison and house two Westinghouse Four-Loop pressurized water reactors, Unit 1 and Unit 2, which first began operation in September 1985 and August 1987 respectively. The plant is currently owned and operated by Constellation Energy. The plant provides electricity to northern Illinois and the city of Chicago. In 2005 it generated on average about 2,450 MWe, enough power to supply about 2 million average American homes. The station employs over 600 people, mostly from Ogle and Winnebago counties, and features two prominent cooling towers.

Electric Power Transmission
Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation. The interconnected lines that facilitate this movement form a ''transmission network''. This is distinct from the local wiring between high-voltage substations and customers, which is typically referred to as electric power distribution. The combined transmission and distribution network is part of electricity delivery, known as the electrical grid. Efficient long-distance transmission of electric power requires high voltages. This reduces the losses produced by strong currents. Transmission lines use either alternating current (HVAC) or direct current (HVDC). The voltage level is changed with transformers. The voltage is stepped up for transmission, then reduced for local distribution. A wide area synchronous grid, known as an "interconnection" in North America, directly connects generators delivering AC power with the same rela ...

Clinton Nuclear Generating Station
The Clinton Power Station is a nuclear power plant located near Clinton, Illinois, USA. The power station began commercial operation on November 24, 1987 and has a nominal net electric output of 1062 MWe. Due to inflation and cost overruns, Clinton's final construction cost was $4.25 billion ($ today), nearly 1,000% over the original budget of $430 million and seven years behind schedule. The station has a single generation II General Electric Boiling Water Reactor. The present reactor operating license was issued April 17, 1987, and will expire September 29, 2026. Plans for a second reactor were shelved. Exelon, the former owner and operator of the present reactor, announced plans to permanently close the power station in June 2017, due to the plants struggles to compete economically in wholesale markets, resulting in a loss of millions of dollars in recent years.Dianne CardwelExelon to Close 2 Nuclear Plants in Illinois June 2, 2016.

MW·h
A kilowatt-hour (unit symbol: kW⋅h or kW h; commonly written as kWh) is a unit of energy: one kilowatt of power for one hour. In terms of SI derived units with special names, it equals 3.6 megajoules (MJ). Kilowatt-hours are a common billing unit for electrical energy delivered to consumers by electric utilities. Definition The kilowatt-hour is a composite unit of energy equal to one kilowatt (kW) sustained for (multiplied by) one hour. Expressed in the standard unit of energy in the International System of Units (SI), the joule (symbol J), it is equal to 3,600 kilojoules or 3.6 MJ."Half-high dots or spaces are used to express a derived unit formed from two or more other units by multiplication.", Barry N.
