Southwest Power Pool

Southwest Power Pool Seasonal API

Seasonal ratings are static ratings associated with extended durations, typically months. These are typically used in both planning and operations. Power system resources that are exempt from providing AARs generally operate at a seasonal rating. Even for resources using dynamic ratings, a seasonal rating is still necessary. This acts as a recourse when a dynamic rating is unavailable. For example, a dynamic rating might be unavailable during communication outages or for forecasts beyond the ten-day period required by FERC Order 881.
