The operator’s own caveats

This dataset provides the approved commercial technical import and export limits for each Grid Supply Point (GSP) where formal technical limits have been assessed and accepted.
All information and data on the data portal is provided “as is”.

non additive: true
notes: ["A technical limit is the import or export ceiling agreed at the GSP under which conditional connection offers are made ahead of transmission works: a limit on total flow, hence availability_type total, not headroom.","No unit is stated anywhere in the dataset, its XLSX or the package; MW is the unit of GB technical limits (NPg labels the same quantity MW). Every value carries unit_stated_by_source = false.","Import limits are published as negative numbers and kept so; one SEPD GSP (Bramley) has a negative export limit, kept and flagged.","The Scenario column is SSEN's period label, carried as the season dimension (winter, spring_autumn, solar_max, solar_min). SHEPD rows are labelled by assessment batch instead; a batch is not a period, so those values have no season and the batch is in their details.","GSPs are named, not coded: the GSP name is the identity."]
