A Survey of Capacity Mechanisms: Lessons for the Swedish Electricity Market
综述全球电力市场容量机制,指出在依赖大量可变可再生能源和水电的地区(如瑞典),设计得当的战略储备比市场范围容量机制更有效。
Many electricity markets use capacity mechanisms to support producers. Capacity payments can mitigate imperfections associated with “missing money” in the spot market and solve transitory capacity shortages caused by investment cycles, regulatory changes, or technology shifts. We discuss capacity mechanisms used in electricity markets around the world. We argue that correctly designed strategic reserves are likely to be more efficient than market-wide capacity mechanisms in jurisdictions that rely on substantial amounts of variable renewable energy and hydro power for electricity supply, such as Sweden.
