阿拉斯加州电网升级获联邦支持 4.18亿美元新建223英里跨区输电线
美国能源部10月5日宣布，拟动用《国防生产法》资金，支持阿拉斯加州能源局（Alaska Energy Authority）推进贝卢加（Beluga）至希利（Healy）输电项目：联邦最高投入1.5亿美元，州及地方等非联邦资金配套2.68亿美元，计划总投资4.18亿美元。项目将新建一条长约223英里的高压输电线路，连接南中央地区的贝卢加与内陆地区的希利，为阿拉斯加人口最稠密的「铁路带」（Railbelt）电网增添第二条高压走廊，把两大区域的电源与负荷更紧密地联结起来。铁路带电网承担全州约四分之三人口的用电，长期依赖单通道输电，一旦线路因极端天气或设备故障中断，大片地区可能面临停电风险。能源部表示，该项目是运用国防生产法强化关键能源基础设施、提升电网韧性的一揽子安排的一部分；州能源局将负责后续设计、许可与建设推进。阿拉斯加冬季漫长，取暖与日常生活高度依赖电力供应，电网可靠性直接关系民生与安全，这条新线路因此被视为该州多年来最重要的电力基建项目之一。（来源：美国能源部）
Alaska Railbelt Grid Upgrade Wins Federal Backing: $418 Million for a 223-Mile Transmission Line
The U.S. Department of Energy announced on October 5 that it plans to use Defense Production Act funding to support the Alaska Energy Authority's Beluga-to-Healy transmission project: up to $150 million in federal funds matched by $268 million in non-federal investment, for a planned total of $418 million. The project would build about 223 miles of new high-voltage transmission line linking Beluga in Southcentral Alaska with Healy in the Interior, giving the Railbelt grid — which serves about three-quarters of the state's population — a second high-voltage corridor between its two major load regions. The Railbelt has long depended on a single transmission path, so an outage caused by extreme weather or equipment failure can put large areas at risk of blackouts. The Energy Department said the project is part of a broader effort to use the Defense Production Act to strengthen critical energy infrastructure and grid resilience, with the state energy authority leading design, permitting and construction. In a state where long winters make heating and daily life deeply dependent on electricity, the new line is widely viewed as one of Alaska's most important power projects in years.
