據能源轉型新聞2021年4月1日紐約報道，為了在2030年前將二氧化碳排放量從2005年的水平減少85%，美國風能領域領先企業艾克塞爾能源公司3月31日向科羅拉多州能源監管機構提出了一項全面的清潔能源轉型計劃。這個清潔能源轉型計劃將加速其在科羅拉多州的子公司公共服務公司通過更多地依賴新的風能、太陽能和能源儲存資源來擺脫燃煤發電。

艾克塞爾能源公司科羅拉多分公司總裁愛麗絲· 杰克遜在向科羅拉多州公共事業委員會提交的關于艾克塞爾能源公司2021年清潔能源計劃的書面證詞中說，“這項資源計劃是我們公司歷史上提出的最大、最受氣候驅動的提案。”

艾克塞爾能源公司首選的采購方案包括，到2030年前新增大約5100兆瓦的可再生能源資源，包括2300兆瓦的風力發電、1600兆瓦的大規模太陽能發電和1200兆瓦的分布式太陽能發電，以及400兆瓦的電池儲能和1300兆瓦的“靈活可調度發電”。

靈活可調度發電方式可以是天然氣或其他資源，這些資源可以通過全源提案請求來選擇。

艾克克塞爾能源公司還希望在科羅拉多州東部平原建設長560英里345千伏的輸電線路，以滿足丹佛、普韋布洛、科羅拉多斯普林斯、博爾德和柯林斯堡地區人口中心的需求。

總的來說，艾克塞爾能源公司計劃在發電資源上花費54億美元，在輸電上花費17億美元。艾克塞爾能源公司估計，在2024年至2030年期間，平均每年對電價的影響為2.6%。

Xcel Energy accelerates clean energy transition, coal exit in Colorado

Aiming to slash carbon-dioxide emissions 85% by 2030 from 2005 levels, Xcel Energy Inc. on March 31 pitched Colorado energy regulators a sweeping clean energy transition that would accelerate subsidiary Public Service Co. of Colorado's move away from coal-fired generation by leaning more heavily on new wind, solar and energy storage resources.

"This resource plan is the largest and most climate-driven proposal brought forward in our company's history," Alice Jackson, president of Xcel Energy's Colorado affiliate, said in written testimony to the Colorado Public Utilities Commission on the utility's 2021 clean energy plan.

The company's preferred procurement scenario includes the addition of roughly 5,100 MW of renewable energy resources by 2030, including 2,300 MW of wind power, 1,600 MW of large-scale solar and 1,200 MW of distributed solar, as well as 400 MW of battery storage and 1,300 MW of "flexible dispatchable generation."

The flexible generation could be natural gas or other resources selected through an all-source request for proposals.

Xcel Energy also wants to build 560 miles of 345-kV transmission lines to harness renewable energy resources in Colorado's eastern plains for demand in population centers in the Denver, Pueblo, Colorado Springs, Boulder and Fort Collins areas.

In total, Xcel Energy proposes spending almost $5.4 billion on generation resources and $1.7 billion on transmission. The utility estimates an average annual rate impact of 2.6% between 2024 and 2030.
