Exploration on market-driven capacity compensation mechanism

doi:10.3969/j.issn.2097-0706.2023.06.011

Abstract

Abstract:

With the development of renewable energy and electricity spot market， the functional repositioning of coal-fired units leads to stranded costs. To ensure sufficient generation capacity adequacy and reliable operation of the power system， a capacity compensation mechanism need to be introduced to power market. A capacity compensation mechanism aiming to provide electricity market incentives is designed. summarizing the implementation process of the capacity compensation mechanism， the assorted clearing， assessment， adjustment， and information disclosure mechanism. The analysis results provide a reference for other provinces exploring capacity cost recovery mechanisms.

Key words: coal-fired units, capacity compensation mechanism, cost recovery, electricity market, cost deficit, capacity compensation clearing
