电网投资节奏跟踪——2026年8月

电网投资节奏跟踪— 2026 年 8 月

报告要点

电网迈入成长周期,需重点关注招标节奏变化。“十五五”期间“六张网”建设将拉动超 5 万亿元电网投资,未来五年投资 CAGR 有望超过 10%。2015-2023 年国内电网年投资额维持在 5000 亿元左右,2024-2025 年上移至6000 亿元级别,我们预计“十五五”末有望突破万亿元,电网投资将迈入新一轮成长周期。电网行业兼具竞争格局稳定的“防御”属性与稳健成长的“进攻”属性,配置价值显著。本系列报告将持续跟踪电网招标规模、投资节奏及主要企业中标份额变化,把握产业链边际变化,研判行业景气趋势与投资价值。

电网投资保持稳健增长,2026年 8月单月增速明显回升,电网与电源投资增速持续分化。2026 年1-8月,全国电网基本建设投资完成额 3932亿元,同比增长 3.6%,其中 8 月单月完成投资 592 亿元,同比增长 23.1%,较7 月明显回升;同期电源基本建设投资完成额 4916 亿元,同比下降 1.5%,其中 8 月单月同比下降 3.6%。电网投资自 2025 年以来多数时间领先于电源投资,反映出电力系统投资重心逐步向电网侧倾斜。考虑到电网投资具有明显的季节性特征,四季度有望迎来投资高峰。

主网输变电设备招标规模同比下滑,主要设备企业竞争格局整体稳定。2026年国网输变电设备前4批招标金额合计601亿元,同比下降12%,较2025年全年 26%的同比增速明显放缓。从竞争格局来看,一次设备头部企业中标份额整体稳定,二次设备龙头优势进一步巩固,国电南瑞前 4 批继保及变电监控设备中标份额达 31.1%,较 2025 年全年提升 3.7个百分点。当前主网设备招标增速与电网投资增速有所背离,后续需重点关注剩余批次招标节奏及订单释放情况。

计量设备招标规模同比回暖,新标准切换后的需求修复值得关注。2026 年国网计量设备第 1 批招标金额约 73.5 亿元,同比增长6%,较 2025年全年52%的同比降幅明显改善。2025 年招标规模大幅下滑,主要受 2024年高基数、采购节奏调整及智能电表新旧标准切换影响,部分采购需求延后释放。从竞争格局来看,计量设备市场集中度较低,头部企业中标份额整体稳定。随着新标准电表逐步推广及前期延后需求释放,计量设备招标规模有望逐步修复。

风险提示: 1、电网设备招标规模不及预期风险;2、电网项目建设进度不及预期风险;3、行业竞争加剧风险;4、原材料价格波动风险。

电网投资保持稳健增长,电源投资延续负增长态势,电网与电源投资增速持续分化。2026年1-8月,全国电网基本建设投资完成额3932亿元,同比增长 3.6%;其中 8月单月完成投资592亿元,同比增长23.1%,较7 月明显回升,反映出电网投资节奏有所加快。从历史季节性规律来看,电网投资通常呈现年末集中放量的特征,四季度有望迎来投资高峰。相比之下,电源侧投资表现相对疲弱,2026 年1-8 月全国电源基本建设投资完成额 4916 亿元,同比下降1.5%;其中8月单月完成投资679 亿元,同比下降 3.6%,延续年内负增长态势。整体来看,电网投资增速自 2025 年以来多数时间领先于电源投资,反映出电力系统投资重心正逐步向电网侧倾斜。随着新能源装机规模持续扩大,电网消纳能力、跨区域输电及系统调节能力的重要性不断提升,我们预计电网投资有望维持较高景气度。

2026年主网输变电招标规模同比有所下滑,主要设备企业中标格局整体稳定。2026年国网输变电设备前 4 批招标金额合计 601 亿元,同比下降 12%,较 2025 年全年 26%的同比增速明显放缓,反映出主网设备招标节奏阶段性偏弱。从竞争格局来看,组合电器、变压器等一次设备市场格局整体稳定,头部企业仍占据较高市场份额;二次设备方面,国电南瑞 2026年前 4 批中标份额达 31.1%,较 2025 年全年提升 3.7 个百分点,龙头地位进一步巩固。整体来看,主网设备招标金额与电网实际投资增速出现一定背离,考虑到招标向设备交付及投资完成的传导存在一定时滞,短期招标波动尚不能直接代表全年电网投资趋势,后续需重点关注国网剩余批次招标规模及主网设备订单释放节奏。

2026 年国网电表第 1 批招标同比回暖,市场竞争格局整体稳定。2026 年国网计量设备第批招标金额约73.5亿元,同比增长6%,较 2025年全年52%的同比降幅明显改善。2025 年招标金额大幅下滑,主要系两方面原因:一是 2024 年智能电表招标规模处于高位,形成较高基数,叠加2025年采购节奏调整,招标需求有所回落;二是智能电表新旧技术标准切换,2025年第3批电能表招标因采用新标准出现流标,部分采购需求延后至 2026年释放,同时电表中标价格下降进一步拖累招标金额。从竞争格局来看,计量设备市场集中度较低,头部企业中标份额普遍处于2%—5%区间,整体格局相对稳定。展望后续,随着新标准电表逐步推广及前期延后需求释放,计量设备招标规模有望逐步修复。
