%3c/svg%3e>) 人工智能加速发展，算力中心用电需求随服务器上架率动态增长。若按满负荷规模一次性建成配套电网，往往面临前期容量大量闲置、投资效益偏低的困境。 瞄准这一痛点，国网无锡供电公司探索“阶梯投运”模式——分阶段灵活扩容，让电网建设跟着算力上架的节奏“长”起来。 7月27日，在中国移动长三角（无锡）马山算力中心用户变电站内，客户经理张銮喜手持红外测温仪，正在对高负荷运行下的电力设备逐一巡检。 这座“东数西算”长三角枢纽重点项目，正是“阶梯投运”模式的受益项目。据悉，马山算力中心总投资超102亿元，峰值算力达17.88EFLOPS。三期用电需求从1.05万千伏安跃升至11万千伏安，若一次性建成20万千伏安配套网架，前期闲置超18万千伏安，资源利用率不足10%。 为了让每一阶段容量匹配算力上架进度，当地供电公司将配套网架分三步投运：一期（2023年底）2路10千伏专线，容量15960千伏安；二期（2024年）新增2路10千伏专线，容量翻倍至31920千伏安；三期（2026年）2路110千伏专线，整体供电规模突破20万千伏安。 同时，依托“开门接电”示范区提前铺设的9.7公里外线网架，企业无需自行开展外线施工，每期直接“即插即用”接电。 国网无锡供电公司营销部副主任李向超介绍：“分阶段扩容让电网跟着算力上架节奏走，既避免了固定资产闲置，也大幅提升了资源利用效率。9.7公里外线工程节省造价约1200万元，项目整体投产提前了120天，带来算力营收增量超千万元。” 从“一次建成”到“弹性生长”，国网无锡供电公司正以“电力先行、灵活适配”的实践，为AI时代算力底座提供坚实保障。 记者：张子晴
