前期受北美AIDC缺电概念影响，电网板块持续走强。当前北美AI产业快速发展，市场对北美算力需求 将大幅增长已达成共识。北美官方机构此前预测未来5年数据中心累计装机量约为30-100GW的水平，而 北美AIDC实际需求可能不断超出预期。面对负荷不断增长的巨大压力，当前北美电源电网难以应对。 根据长江证券的测算，在不考虑大区电网互联带来的抵消作用下，2025-2030年美国将合计产生约 73.2GW的电力总缺口，若数据中心增长超预期，则可能产生201GW的电力总缺口。2025-2027年将是压 力最大的阶段，随着2028年有效电源预测装机的集中投运，压力将稍有缓解，但依然存在一定的电力缺 口。总体来看，未来美国缺电情况将会愈演愈烈。预计美国缺电或将会带动储能、电气设备、电网设备 等领域的出海发展。 2025年1-9月，我国变压器累计出口金额为350.92亿元，同比增长52.73%，呈现高增长态势。国内企业 凭借特高压、智能电网等大型工程积累的技术和经验，在海外市场优势明显。 今日，电网板块回调，电网ETF（561380）跌超1.5%，盘中溢价交易。 电网ETF跟踪恒生A股电网设备指数，电网设备占比超半数，覆盖电网 ...
