Overview
State Grid’s 15th Five-Year fixed-asset investment is projected at about 4 trillion yuan, up roughly 40% from the 14th plan; Southern Grid’s 2026 capex has grown for five straight years. On Sept 16, State Grid pledged to connect over 60 GW of new distributed generation per year through the plan period — about 180-240bn yuan of direct investment — and to publish distributary-grid open-capacity information.
Background & Interpretation
1. Industry and Policy Context
New power-system construction is at a crunch point, targeting over 2.8 billion kW of high-quality renewable消纳 by 2030. NDRC Order 41 makes grid-forming capability (e.g. low-voltage ride-through) mandatory for storage above 220kV from July 1, 2026, or face major-accident classification.
2. Core Drivers and Mechanism
Grid build-out is shifting from lagging to proactive, driven by renewable integration pressure, AIDC compute clusters’ low-latency power demand, and a unified national power market. Quarterly publication of open capacity turns “ask to know” into “check in advance”, removing the biggest uncertainty for distributed investors.
3. Market Structure and Impact
Demand rises for transformers, SVG, STATCOM and grid-forming PCS; transformer exports stay strong with higher margins. Silicon-steel prices tick up but remain near bottom, supporting vendor margins.
Implications & Outlook
Grid investment certainty is high; the supply chain spurred by main-distribution, storage and charging coordination far exceeds grid capex alone. Watch 15th-plan tender pace and compute-power synergy policy.
Takeaways for Industry Participants
Equipment firms: pre-build grid-forming and ride-through capability. Distributed investors: check regional open capacity before investing to avoid saturated nodes. Parks and data centres: prioritise high-green-share siting and source-grid-load-storage integration.
