日本語
中国の10,032基の風力発電所を1989〜2022年にわたり再構築し、技術的に利用可能な発電量の20%超が未利用であることを示した。系統接続遅延や公式報告の出力抑制は過去10年で約70%減少した一方、系統の柔軟性不足や規制歪みに起因する未報告の「ソフト抑制」が新たに支配的となっている。蓄電池や柔軟な需要とのマッチングにより、2060年の風力目標を最大13年前倒しでき、累積20Gt超のCO₂削減が可能と試算する。
English
Reconstructing generation for 10,032 Chinese wind farms (1989-2022), the authors find over 20% of technically available generation goes unused. While grid-connection delays and reported curtailment fell ~70% over the past decade, a residual 'soft curtailment' from system inflexibility and regulatory distortions now dominates, offsetting expected capacity-factor gains. Storage and flexible-load matching could reach China's 2060 wind target up to 13 years earlier, avoiding over 20 Gt CO₂ cumulatively.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
中国の再エネ大量導入に伴う系統柔軟性・規制設計の課題は、日本の再エネ大量導入・出力抑制政策やGX電源投資の議論にも直接示唆を与える。未報告損失の可視化は、企業の再エネ調達や電力調達リスク評価にも関連する。
In the global GX context
This work sharpens the global transition-finance and disclosure debate by quantifying unreported renewable losses ('soft curtailment') that standard curtailment metrics miss—relevant to ISSB/TCFD energy-transition risk and to investors assessing real vs. nominal renewable capacity growth.
👥 読者別の含意
🔬研究者:Offers a decomposition method separating reported curtailment from unreported system/regulatory losses, transferable to other markets.
🏢実務担当者:Highlights that nominal renewable capacity may mask utilization losses, informing power procurement and transition-risk assessment.
🏛政策担当者:Shows grid flexibility and dispatch/tariff design, not just capacity build-out, determine decarbonization outcomes.
📄 Abstract（原文）
<title>Abstract</title> <p>Wind power is pivotal to global decarbonization, and China leads in both installed capacity and recent expansion. Yet rapid capacity expansion has not translated into commensurate growth in usable electricity. Here we reconstruct generation for 10,032 wind farms in China spanning 1989-2022 and find that over 20% of technically available generation is not utilized. Decomposition reveals that while grid-connection delays and officially reported curtailment have declined by ~70% in the past decade, a residual component - soft curtailment - has emerged. This component represents unreported losses arising from system inflexibility and regulatory distortions, such as rigid dispatch, strict curtailment targets, and premature reporting of grid connection incentivized by feed-in tariff policies. Soft curtailment now dominates wind power underperformance in China, offsetting technological improvements expected to raise capacity factors by ~20%, leaving them largely unchanged overall. Absorbing the unrealized generation through storage at multiple timescales and matching to flexible loads could enable China to reach its 2060 wind generation target for carbon neutrality up to 13 years earlier and avoid over 20 Gt CO₂ emissions cumulatively.</p>
