摘要

2021年1月，尽管没有发生自然灾害，但日本电力现货市场经历了持续40多天的严重功能失调。在此期间，价格从10日元/千瓦时飙升至251日元/千瓦时，这是日本电力市场历史上前所未有的事件。研究表明，这一事件与相关制度的设计有因果关系，不仅未能提供有效的对冲机制，而且加剧了外生因素对电力现货市场的负面影响。具体而言，主要原因包括电力非均衡定价机制不完善、信息收集和披露制度不健全、电力公司内部可能存在交叉补贴、市场风险分散机制不完善等。

A revisiting of 2021 Japanese electricity spot market dysfunction event: How it happened and what can we learn from it?

In January 2021, despite the absence of natural disasters, Japan's electricity spot market experienced a significant dysfunction lasting more than 40 days. During this period, prices surged from 10 JPY/kWh to 251 JPY/kWh, an unprecedented event in Japan's electricity market's history. Research indicates that this incident is causally linked to the design of relevant institutions, which not only failed to provide effective hedging mechanisms but also exacerbated the negative impact of exogenous factors on the electricity spot market. Specifically, the primary causes include an imperfect pricing mechanism for unbalanced power, inadequate systems for information collection and disclosure, potential cross-subsidies within incumbent power companies, and impractical market risk diversification mechanisms.

期刊介绍： Energy policy is the manner in which a given entity (often governmental) has decided to address issues of energy development including energy conversion, distribution and use as well as reduction of greenhouse gas emissions in order to contribute to climate change mitigation. The attributes of energy policy may include legislation, international treaties, incentives to investment, guidelines for energy conservation, taxation and other public policy techniques. Energy policy is closely related to climate change policy because totalled worldwide the energy sector emits more greenhouse gas than other sectors.
