据高盛此前发布的报告，当前，美国数据中心容量占全球的44%，已消耗美国约6%的电力，预计到 2030年，这一比例将上升至11%，而衡量电网可靠性的有效备用电力容量指标却从5年前的26%降至 19%。在全美13个区域电网中，8个已达到或低于该临界值，弗吉尼亚州等数据中心密集地区均出现电 价飙升现象。 据彭博社报道，当地时间1月7日，全球知名投行高盛表示，在数据中心用电需求迅猛增长的背景下，到 2030年，美国几乎所有电力电网都将面临备用容量不足的问题，或为中国在人工智能竞争中取得先发优 势提供机遇。 "如果电力约束持续存在，中国有可能在AI竞赛中实现反超。"高盛全球大宗商品研究联席主管Samantha Dart直言，美国的新增发电能力跟不上需求增长。按行业惯例，电网需要保持至少15%的备用裕度，才 能在峰值负荷与可用发电能力间形成安全空间。但目前，美国部分电网已低于这一水平，随着数据中心 持续拉动用电需求，备用不足的问题在未来几年只会进一步恶化。 与此形成鲜明对比的是，中国电力供应展现出强大韧性。高盛报告指出，预计到2030年，中国将拥有约 400吉瓦的备用电力容量，达到全球数据中心预期总需求的3倍以上。 ...
