Deregulation in electricity markets has changed the conditions for maintaining long-term adequacy of supply. Particularly in the last decade, security of supply has become a major issue for policymakers due to a number of changes in technology, especially the introduction of renewables, where regulators have introduced capacity mechanisms. In this paper, we focus on the use of two different capacity mechanisms: procurement for long-term strategic reserves contracting, and centralized auctioning for capacity contracts. We investigate the effect of uncertainty on the effectiveness of these two mechanisms in maintaining a stable and sufficient supply of capacity. We use simulation to establish the behavior as the level of uncertainty is increased. Our results suggest that a market's level of uncertainty plays an important role in the effectiveness of these two interventions. The results raise questions about when it is appropriate to introduce either of them.
