This study examines the effects of curtailment costs on cost-minimized energy capacity for Metro Vancouver, focusing on electrification and Renewable Gas (RG) pathways. Using Calliope, we assess the impact of curtailment costs on storage capacity, renewable generation, and system costs. Results show that curtailment costs significantly affect the electrification pathway, driving increased battery storage activity and selective deployment of renewable generation to limit curtailment. In contrast, the RG pathway adjusts only gas storage capacity in response to curtailment costs, relying solely on wind technology as its Variable Renewable Energy source without the need of an electric storage. These findings highlight the importance of tailored curtailment cost strategies for efficient renewable integration, enhancing resilience and cost-effectiveness across energy transition pathways.
