Résumé The expansion of intermittent renewable electricity increases supply variability and requires greater flexibility from consumers. This results in welfare losses for agents who are averse to fluctuations. Our model analyzes these welfare consequences by considering short-term and exogenous variability in renewable energy generation. We explore an optimal control problem that determines a welfare-maximizing electricity consumption path by controlling dispatchable energy and storage. This optimization problem identifies three scenarios: no active storage, abundant storage capacities and limited capacities. We then derive an overall consumer welfare function for alternative energy mixes. This allows us to assess the welfare effects of changing the energy mix. In particular, we consider the substitution of dispatchable fossil-fueled energy generation by renewable energy.

Résumé The expansion of intermittent electricity increases supply variability and requires greater flexibility from consumers. This results in welfare losses for these agents, which can nevertheless be mitigated by energy storage. Our model analyzes these welfare consequences in the context of short-term variability in renewable energy given fixed dispatchable and storage capacities. We explore an optimal control problem that determines a welfare-maximizing electricity consumption path by adjusting dispatchable and stored energy throughout the short-term production cycle of renewables. This optimization problem identifies three regimes (no storage and active storage, with or without capacity constraints) and provides the associated consumer welfare over this cycle. Under all three regimes, a certain degree of consumer flexibility is part of the optimal solution and entails welfare losses. Active storage reduces these losses but cannot eliminate them completely due to the energy conversion losses induced by this activity. However, when storage capacity is constrained, a proactive adjustment of this capacity can offset the losses.
