能源部拟动用《国防生产法》资金最高5000万美元 扩容弗吉尼亚与西弗吉尼亚输电网 新增约290兆瓦容量
华盛顿——美国能源部10月16日宣布，拟动用《国防生产法》（Defense Production Act）资金，加快扩大弗吉尼亚州与西弗吉尼亚州的输电容量，以加强电网可靠性以及对国防至关重要的基础设施。弗吉尼亚州能源局（Virginia Energy）的「弗吉尼亚与西弗吉尼亚大负荷增长电网增强技术」项目将获得最高5,000万美元的《国防生产法》资金，用于在现有输电线路上部署先进输电技术，提高电力输送能力、减少线路拥堵，并支持该地区不断增长的能源需求。
能源部表示，该项目将在现有输电走廊沿线采用先进换线（advanced reconductoring）与动态线路评级（Dynamic Line Rating）技术，为阿巴拉契亚电力公司（Appalachian Power）的弗吉尼亚系统新增约290兆瓦输电容量，进度比传统输电升级快一至四年。能源部称，这些改进将使电网更加可靠、降低用电成本，并帮助确保该地区的社区、企业、军事行动以及政府和国防相关产业在用电高峰或供电中断时也能获得稳定电力。
在资金背景方面，能源部表示，随着特朗普总统签署《工作家庭减税法》（Working Families Tax Cut），联邦已拨款10亿美元用于被认定对国家安全至关重要的能源项目。第2026-10号总统决定（Presidential Determination No. 2026-10）将输电线路与导体、变电站以及电力控制与保护设备列为国防必需物资。
能源部长克里斯·赖特（Chris Wright）表示：「特朗普总统致力于尽一切可能加强美国能源安全、降低美国人民的成本。」他说：「通过动用《国防生产法》资金来保障和扩大弗吉尼亚州与西弗吉尼亚州的电力供应，本届政府正在为未来数十年加强国家的能源安全。」电力办公室助理部长凯蒂·杰雷扎（Katie Jereza）表示：「更强大的电网并不总是意味着修建更多输电线路，有时意味着更好地利用已有的线路。」她说，这项投资将帮助释放更多电力、加强可靠性，并确保电网能够满足美国家庭、企业和国防不断增长的需求。
该拟议项目工期为48个月，由弗吉尼亚州能源局牵头，联合阿巴拉契亚电力公司、波托马克爱迪生公司（Potomac Edison）及地区伙伴实施，旨在演示先进导体与实时输电监测技术如何利用现有基础设施扩大容量。能源部表示，该项目还将通过部署先进技术与材料加强美国国内供应链，并改善电网性能。
Energy Department to Deploy Up to $50 Million in Defense Production Act Funding to Expand Transmission Capacity in Virginia and West Virginia
WASHINGTON — The U.S. Department of Energy (DOE) announced on October 16 its intent to deploy Defense Production Act (DPA) funding to accelerate the expansion of transmission capacity in Virginia and West Virginia, strengthening grid reliability and infrastructure essential to national defense. Virginia Energy's Grid Enhancing Technologies for Virginia & West Virginia Large Load Growth project will receive up to $50 million in DPA funding to deploy advanced transmission technologies across existing power lines to increase electricity delivery capacity, reduce congestion, and support growing energy demand across the region.
According to DOE, the proposed project will deploy advanced reconductoring and Dynamic Line Rating technologies along existing transmission corridors, adding an estimated 290 megawatts of transmission capacity across Appalachian Power's Virginia system, one to four years faster than conventional transmission upgrades. DOE said the improvements will make the power grid more reliable, lower electricity costs, and help ensure that communities, businesses, military operations, and government and defense-related industries across the region have dependable power, especially during times of high demand or power disruptions.
DOE said that, following President Trump's signing of the Working Families Tax Cut, $1 billion in federal funding has been appropriated for energy-related projects deemed critical to national security. Presidential Determination No. 2026-10 identifies transmission lines and conductors, substations, and power-control and protection equipment as essential to national defense.
"President Trump is committed to doing everything possible to strengthen American energy security and lower costs for the American people," said U.S. Secretary of Energy Chris Wright. "By deploying Defense Production Act funding to secure and expand electricity access in Virginia and West Virginia, the Trump Administration is strengthening the nation's energy security for decades to come." Katie Jereza, Assistant Secretary of the Office of Electricity, said: "A stronger electric grid doesn't always mean building more power lines. Sometimes it means making better use of the ones we already have. This investment will help unlock more power, strengthen reliability, and ensure our grid can meet the growing demands of American families, businesses, and national defense."
Led by Virginia Energy in coordination with Appalachian Power, Potomac Edison, and regional partners, the proposed 48-month project will demonstrate how advanced conductors and real-time transmission monitoring technologies can expand capacity using existing infrastructure. DOE said the project also aims to strengthen domestic supply chains through the deployment of advanced technologies and materials and to improve grid performance.
