What is the designated rebidding period for the Day-Ahead market?

The designated rebidding period for the Day-Ahead market is indeed from 4 to 6 pm. This period is crucial as it allows market participants to adjust their bids based on the latest information regarding demand, generation availability, and any other market changes that might have occurred throughout the day.

During this time, participants can modify their offers or schedules in response to updates, ensuring that the market is as efficient as possible by reflecting the most current conditions and expectations. Such adjustments are essential for balancing supply and demand effectively in the subsequent operating day.

The timing of this rebidding period is specifically structured to facilitate a smooth transition from the Day-Ahead market to the real-time market operations, thereby fostering a reliable and responsive electricity market system.
