本論文は、中国、米国、EUの電力部門のカーボンニュートラル移行を比較。再生可能エネルギーの導入拡大に伴い、経済的ボトルネックが発電コストから柔軟性・送電へ移行することを示す。EUの排出権取引制度や米国の税額控除、中国の石炭併用型インフラなど、各国の政策の違いを分析し、柔軟性の価値と市場設計の重要性を強調。
English
This paper compares carbon-neutral power transitions in China, the US, and the EU. It finds that as renewable energy penetration increases, economic bottlenecks shift from generation costs to flexibility and grid transmission. It analyzes differing policy mixes—EU's ETS and market integration, US technology-neutral tax credits, China's coal-backup infrastructure—and highlights the need for flexibility compensation and robust market signals.

📄 Abstract（原文）
Carbon neutrality is currently accelerating the decarbonization process in the power sector. However, China, the United States, and the European Union are taking significantly different transformation paths. This article uses an energy economics framework to link binding system constraints, policy combinations, and the overall system costs to compare the differences among the three countries. This analysis integrates evidence from international assessments and peer-reviewed studies regarding the value and flexibility of variable renewable energy (VRE). The results show that as the share of renewable energy increases, economic bottlenecks shift from generation costs to flexibility and grid transmission: the marginal market value of wind and solar energy decreases as penetration rates increase, while the value of dispatchable system services increases. The EU's total control and trading system and market integration enhance long-term scarcity expectations, but without appropriate hedging designs, they increase the risk of short-term price fluctuations. The United States relies more on technology-neutral tax credits to reduce capital costs and accelerate deployment in the absence of a national carbon price. China combines large-scale clean infrastructure construction with continuous coal supply guarantees, which makes flexibility compensation, inter-provincial transmission, and reliable emission limits key to achieving cost-effective decarbonization. For China, the policy impact lies in regarding flexibility as a decarbonization asset, strengthening market signals through improved monitoring, reporting, and verification (MRV), and reducing power outages through grid and market reforms.
