Cross-border effects of capacity mechanisms: Do uncoordinated market design changes contradict the goals of the European market integration?

摘要

This paper analyses cross-border effects of a strategic reserve (SR) and reliability options (ROs) based on a two-country simulation model. Using a game-theoretic approach, the countries' policy options for capacity remuneration mechanisms (CRMs) are analysed with respect to welfare and distribution effects. An SR tends to narrow down the market, while ROs intensify price competition. However, cross-border effects are most likely negative for consumers and producers in total in the case of a unilateral implementation of a CRM, and market design changes should be coordinated.
