**Dominion withheld capacity from the market **

Dominion's decision to withhold capacity from the market during the auction significantly impacted capacity prices. Previously, Dominion had opted out of the capacity auction, choosing to rely on internal resources. However, they rejoined the auction but excluded their solar and renewable sources from participation, influenced by concerns over the substantial penalties observed during Winter Storm Elliott. This strategic choice resulted in fewer available megawatts for auction, leading to higher capacity prices than predicted. The model initially underestimated these prices based on the expectation of additional megawatts from solar that ultimately did not participate due to the fear of penalties.
