Abstract

[fre] Le modèle des marchés électriques décentralisés présente plusieurs défaillances de marché dans l’articulation des décisions de court terme et de long terme. Il ne permet pas d’orienter correctement les investissements en équipements capitalistiques tant de pointe que de base pour aboutir à un parc optimal de production du fait des difficultés très spécifiques de gestion de risque et de l’incomplétude des marchés. Il est dès lors nécessaire d’organiser de façon règlementaire une rémunération des capacités sur des bases crédibles pour, d’un côté, garantir un niveau suffisant d’investissement en équipements de pointe et, de l’autre, accepter la présence d’arrangements verticaux permettant un partage de risque avec les consommateurs, même si ces arrangements constituent des imperfections de marché contraignant la concurrence. [eng] The decentralised electricity market model illustrates several market flaws in the linkage between short-term and long-term decisions. Because of highly specific problems of risk management and market incompleteness, the model does not allow effective allocation of investment in base-load and peak-load capacities leading to an optimal generation system. This makes it necessary to (1) establish regulations to provide a credible basis for remunerating generation capacity, so as to create incentives for investment in peak-load units ; (2) accept vertical arrangements enabling operators to share risk with consumers, even if these arrangements constitute market imperfections that will constrain competition.
