About this data
Each row is one operating metric from MISO's real-time data APIs for one source interval: area control error, net actual interchange, net scheduled interchange or regional north-south transfer. Values are signed, and the direction of each flow or limit follows the source, so a number only makes sense with its metric name. It gives a live view of how balanced MISO is and how much it is importing or moving between regions.
