There are two sets of data required to determine the Claimed MWhs for GIS import projects. The ISO-NE import schedule and hourly generation data. We receive monthly ISONE schedules for GIS import projects, but in order for GIS to determine the Claimed MWhs, importers are required to provide NEPOOL GIS the hourly generation data.
After the hourly generation data is uploaded, the NEPOOL GIS will automatically reconcile the hourly import schedule against the hourly generation data, claiming the lesser of the 2 values.
