據外媒報道，美國能(neng)源(yuan)部下(xia)屬(shu)的(de)美國能(neng)源(yuan)信(xin)息(xi)署(EIA)日前在發布的(de)一份調查報告中預測，由于(yu)2015年到(dao)2019年期間電池儲能(neng)成(cheng)本下(xia)降了72%，美國公用(yong)事業公司(si)將在未來兩年內為電網采購或(huo)部署裝(zhuang)機(ji)容量(liang)為10GW電池儲能(neng)系統。

從(cong)儲(chu)能(neng)項目(mu)開發(fa)商收(shou)集的規劃數(shu)據表明，美國到(dao)2023年將有(you)10GW儲(chu)能(neng)系統并網運(yun)營(ying)，其部(bu)署(shu)量將比2019年運(yun)營(ying)的1GW電池儲(chu)能(neng)系統增加10倍以(yi)上(shang)。美國儲(chu)能(neng)部(bu)署(shu)量迅速增長(chang)的原因可能(neng)得益于加州(zhou)儲(chu)能(neng)激勵法案(an)AB2514號法案(an)促進(jin)，該法案(an)要求加州(zhou)投(tou)資者擁有(you)的公用事業公司(IOU)到(dao)2024年部(bu)署(shu)1,325MW儲(chu)能(neng)系統。  

太陽能+儲(chu)能系(xi)統是新(xin)增(zeng)項(xiang)目最主要的部分  

共址部(bu)署(shu)的(de)太陽(yang)能(neng)(neng)發(fa)電(dian)(dian)設施和電(dian)(dian)池(chi)儲能(neng)(neng)項(xiang)目(mu)數量(liang)(liang)預計(ji)將顯(xian)著增長(chang)。事實上(shang)，這是美國能(neng)(neng)源(yuan)信息署(shu)(EIA)最(zui)為(wei)確定的(de)對于目(mu)前到2023年(nian)儲能(neng)(neng)市場的(de)發(fa)展(zhan)趨勢(shi)。報(bao)告指出，美國計(ji)劃建設約100個配套部(bu)署(shu)電(dian)(dian)池(chi)儲能(neng)(neng)系統的(de)太陽(yang)能(neng)(neng)發(fa)電(dian)(dian)設施，電(dian)(dian)池(chi)儲能(neng)(neng)項(xiang)目(mu)的(de)總裝(zhuang)(zhuang)機容(rong)量(liang)(liang)為(wei)7,689MW，而獨(du)立部(bu)署(shu)的(de)59座(zuo)儲能(neng)(neng)系統的(de)總裝(zhuang)(zhuang)機容(rong)量(liang)(liang)為(wei)3,115MW。  

太(tai)陽(yang)能(neng)開發商也在(zai)加快配套部(bu)署(shu)(shu)電(dian)(dian)(dian)(dian)(dian)池儲(chu)(chu)能(neng)系(xi)統，雖然截至2020年底，大(da)約一半(ban)運行的(de)(de)電(dian)(dian)(dian)(dian)(dian)池儲(chu)(chu)能(neng)系(xi)統是與(yu)風力發電(dian)(dian)(dian)(dian)(dian)設施配套部(bu)署(shu)(shu)，但(dan)到(dao)(dao)2023年，80%的(de)(de)共(gong)址部(bu)署(shu)(shu)項目將是太(tai)陽(yang)能(neng)+儲(chu)(chu)能(neng)系(xi)統。太(tai)陽(yang)能(neng)發電(dian)(dian)(dian)(dian)(dian)設施的(de)(de)可(ke)(ke)(ke)預測發電(dian)(dian)(dian)(dian)(dian)模式(shi)使其成為(wei)一種可(ke)(ke)(ke)以更簡單地(di)與(yu)電(dian)(dian)(dian)(dian)(dian)池儲(chu)(chu)能(neng)系(xi)統配套的(de)(de)可(ke)(ke)(ke)再生能(neng)源，電(dian)(dian)(dian)(dian)(dian)池儲(chu)(chu)能(neng)系(xi)統可(ke)(ke)(ke)以在(zai)在(zai)發電(dian)(dian)(dian)(dian)(dian)量充足且電(dian)(dian)(dian)(dian)(dian)價較低的(de)(de)時候(hou)充電(dian)(dian)(dian)(dian)(dian)，并在(zai)需求峰值期間(jian)放電(dian)(dian)(dian)(dian)(dian)將電(dian)(dian)(dian)(dian)(dian)力輸送到(dao)(dao)電(dian)(dian)(dian)(dian)(dian)網。  

與(yu)此同(tong)時(shi)， 75%的(de)時(shi)間以(yi)上使(shi)用太(tai)陽(yang)能(neng)或風能(neng)充電(dian)(dian)(dian)的(de)共(gong)(gong)址部(bu)署(shu)(shu)電(dian)(dian)(dian)池(chi)儲能(neng)系(xi)統(tong)可以(yi)獲得稅收抵(di)免折(zhe)扣，這是促(cu)進共(gong)(gong)址部(bu)署(shu)(shu)電(dian)(dian)(dian)池(chi)儲能(neng)系(xi)統(tong)的(de)強(qiang)大驅動力(li)。雖然在去年12月只有(you)約2%現(xian)有(you)太(tai)陽(yang)能(neng)發(fa)電(dian)(dian)(dian)設(she)施(shi)與(yu)電(dian)(dian)(dian)池(chi)儲能(neng)系(xi)統(tong)共(gong)(gong)址部(bu)署(shu)(shu)，但計(ji)劃配套部(bu)署(shu)(shu)電(dian)(dian)(dian)池(chi)儲能(neng)系(xi)統(tong)的(de)太(tai)陽(yang)能(neng)發(fa)電(dian)(dian)(dian)設(she)施(shi)將達到(dao)約25%。
