While the majority of generating resources in existing electricity systems are often variable cost generators that set the marginal market price at the variable cost of their operation, net-zero energy systems may rely more on variable renewable energy and battery storage, which have higher fixed costs and lower variable costs. This study investigates the price dynamics of modeled net-zero energy systems under two policies to help understand the dynamics of revenue recovery and the potential hourly distribution of prices for such systems. This research finds that high penetration of renewables may lead to some curtailment of generation, but energy and capacity markets both play ongoing roles in revenue recovery. Wind, solar, battery discharge, electrolytic hydrogen, nuclear, and peaking resources each have hours where their behavior sets energy market prices for the system, and this raises questions about how actual markets may respond to changes in the set of generators participating in their operation.
