美国艾克塞尔能源公司加速清洁能源转型

据能源转型新闻2021年4月1日纽约报道，为了在2030年前将二氧化碳排放量从2005年的水平减少85%，美国风能领域领先企业艾克塞尔能源公司3月31日向科罗拉多州能源监管机构提出了一项全面的清洁能源转型计划。这个清洁能源转型计划将加速其在科罗拉多州的子公司公共服务公司通过更多地依赖新的风能、太阳能和能源储存资源来摆脱燃煤发电。

艾克塞尔能源公司科罗拉多分公司总裁爱丽丝· 杰克逊在向科罗拉多州公共事业委员会提交的关于艾克塞尔能源公司2021年清洁能源计划的书面证词中说，“这项资源计划是我们公司历史上提出的最大、最受气候驱动的提案。”

艾克塞尔能源公司首选的采购方案包括，到2030年前新增大约5100兆瓦的可再生能源资源，包括2300兆瓦的风力发电、1600兆瓦的大规模太阳能发电和1200兆瓦的分布式太阳能发电，以及400兆瓦的电池储能和1300兆瓦的“灵活可调度发电”。

灵活可调度发电方式可以是天然气或其他资源，这些资源可以通过全源提案请求来选择。

艾克克塞尔能源公司还希望在科罗拉多州东部平原建设长560英里345千伏的输电线路，以满足丹佛、普韦布洛、科罗拉多斯普林斯、博尔德和柯林斯堡地区人口中心的需求。

总的来说，艾克塞尔能源公司计划在发电资源上花费54亿美元，在输电上花费17亿美元。艾克塞尔能源公司估计，在2024年至2030年期间，平均每年对电价的影响为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.
