据每日能源网站1月14日消息：美国能源信息署(EIA)的一份新报告称，9.1GW的发电能力计划于2021年被淘汰。其中核能发电占56％，煤炭发电占30％。
具体来说，今年将淘汰5.1GW的核电容量，占美国目前正在运行的核电容量的5％。即将退役的核电站包括Exelon Corp、位于伊利诺伊州的Dresden和Byron核电站，以及纽约州的印第安角核电站。如果五座核电站都如期关闭，2021年将创下历史上最大规模的年度核电淘汰记录。EIA官员表示，由于天然气价格下降、电力需求增长有限以及来自可再生能源的竞争加剧，核能发电能力下降。
此外，今年将有2.7GW的燃煤电厂退役，占美国燃煤电厂总数的1%。最大煤炭退役点将位于马里兰州的Chalk Point、佛罗里达州的Big Bend、康涅狄格州的Bridgeport车站和威斯康星州的热那亚。
另外，还有800兆瓦的石油燃料产能和253兆瓦的天然气燃料产能计划在今年退役。大多数退役产能将来自弗吉尼亚州Possum Point的786 MW机组。最大的天然气退役将是特拉华州的McKee Run(103兆瓦)。

EIA report says 9.1GW of electric generating capacity will be retired in 2021
A new report from the U.S. Energy Information Administration (EIA) says 9.1 gigawatts (GW) of electric generating capacity is scheduled to retire in 2021.
Among the retirements, nuclear generating capacity will account for 56 percent of the retirements, while coal will account for 30 percent of the retirements.
Specifically, 5.1 GW of nuclear capacity will be retired this year, representing 5 percent of the current operating U.S. nuclear generating capacity. Among those nuclear plants that will be retired are Exelon Corp.’s Dresden and Byron plants in Illinois and the Indian Point nuclear power plant in New York state. If all five reactors close as scheduled, 2021 will set a record for the most annual nuclear capacity retirements ever. EIA officials said nuclear power generating capacity gas dropped due to lower natural gas prices, limited electricity demand growth, and increasing competition from renewable energy.
Also, 2.7 GW of coal plants will retire in 2021, which accounts for 1 percent of the U.S. coal fleet. These retirements will come primarily from older units, with two-thirds located in four states: Maryland, Florida, Connecticut, and Wisconsin. The largest coal retirements in 2021 will be at Chalk Point in Maryland, Big Bend in Florida, Bridgeport Station in Connecticut, and Genoa in Wisconsin.
Further, 800 MW of petroleum-fired capacity and 253 MW of natural gas-fired capacity are scheduled to retire in 2021. Most of the retiring petroleum capacity will be from the 786 MW unit at Possum Point in Virginia. The largest natural gas retirement will be McKee Run (103 MW) in Delaware.
