據(jù)美國(guó)能源1月14日?qǐng)?bào)道，EIA預(yù)計(jì)2020年美國(guó)將新增42 GW發(fā)電能力。太陽(yáng)能和風(fēng)能新增約32 GW，占總新增能源的76%。風(fēng)能在這些新增能源中所占比例最大，為44%；其次是太陽(yáng)能和天然氣，分別為32%和22%；余下的2%來(lái)自水力發(fā)電機(jī)和蓄電池。

 

風(fēng)電：運(yùn)營(yíng)商計(jì)劃在2020年實(shí)現(xiàn)18.5 GW的風(fēng)電容量，超過(guò)2012年創(chuàng)下的13.2 GW的紀(jì)錄水平。超過(guò)60%或11.2 GW的風(fēng)電容量計(jì)劃在年底，即2020年11月和12月上線。美國(guó)生產(chǎn)稅抵免（PTC）將于2020年底到期，這將推動(dòng)風(fēng)電容量的大幅增加。EIA預(yù)計(jì)新增風(fēng)電容量將達(dá)到11.8 GW。五個(gè)州占2020年計(jì)劃新增風(fēng)電容量的一半以上，其中得克薩斯州占32%；俄克拉荷馬州占6%；懷俄明州、科羅拉多州和密蘇里州各占5%。

 

太陽(yáng)能光伏：EIA預(yù)計(jì)2020年太陽(yáng)能發(fā)電量將達(dá)到13.5 GW，超過(guò)此前2016年新增8 GW的年度紀(jì)錄。

 

天然氣發(fā)電：2020年計(jì)劃新增天然氣發(fā)電能力為9.3 GW。聯(lián)合循環(huán)發(fā)電廠占6.7 GW，燃機(jī)發(fā)電廠占2.3 GW。超過(guò)70%的新增發(fā)電能力分布在賓夕法尼亞州、得克薩斯州、加利福尼亞州和路易斯安那州。

New electric generating capacity in 2020 will come primarily from wind and solar

 

According to the U.S. Energy Information Administration’s (EIA) latest inventory of electric generators, EIA expects 42 gigawatts (GW) of new capacity additions to start commercial operation in 2020. Solar and wind represent almost 32 GW, or 76%, of these additions. Wind acs for the largest share of these additions at 44%, followed by solar and natural gas at 32% and 22%, respectively. The remaining 2% comes from hydroelectric generators and battery storage.

 

Wind. Operators have scheduled 18.5 GW of wind capacity to come online in 2020, surpassing the record level of 13.2 GW set in 2012. More than 60%, or 11.2 GW, of wind capacity is scheduled to come online at the end of the year, in November and December of 2020. Expiration of the U.S. production tax credit (PTC) at the end of 2020 is driving the large wind capacity addition. EIA expects will total 11.8 GW. Five states ac for more than half of the 2020 planned wind capacity additions. Texas acs for 32%; followed by Oklahoma at 6%; then Wyoming, Colorado, and Missouri at 5% each.

 

Solar photovoltaics. EIA expects 13.5 GW of solar capacity to come online in 2020, surpassing the previous annual record addition of 8 GW in 2016.

 

Natural gas. Planned natural gas capacity additions for 2020 are 9.3 GW. Combined-cycle plants ac for 6.7 GW and combustion-turbine plants ac for 2.3 GW. More than 70% of these additions are in Pennsylvania, Texas, California, and Louisiana.
