All MISO interconnection data follows the standardized response format with MISO-specific fields including seasonal capacity ratings and study cycle information.

​
MISO-Specific Fields

FieldDescription
summer_capacity_mwSummer capacity rating (MW)
winter_capacity_mwWinter capacity rating (MW)
study_cycleDefinitive Planning Phase cycle
study_groupStudy group assignment
Data Updates: MISO queue data is updated based on MISO’s Generator Interconnection Queue reports.
Wind Focus: MISO territory has significant wind resources, particularly in the upper Midwest states. Wind projects typically have seasonal capacity variations reflected in the summer/winter capacity fields.
