Competition policy and regulation in hydro-dominated electricity markets

Abstract: This paper discusses the main competition issues that arise in electricity systems dominated by hydro generation, arguing that technological differences between hydro and thermal plants may allow hydropower producers to exert market power in different and subtler ways compared to thermal generators. The key for market power in hydro-based systems is the strategic allocation of a given amount of output across periods, rather than a straightforward reduction of total output. The paper examines the interaction between strategic hydro reservoir operation and transmission capacity constraints, and summarizes the implications of market power for system reliability. A review of recent relevant literature is included. Finally, possible interventions to mitigate market power are analysed.
