(edit: I see you answered a sibling comment with the same question. TL;DR: Potential output is the output pretending that curtailment did not apply. Thanks!)

A UI or terminology question: when 'Potential output' says it is 'Including curtailment', does this mean that it pretends that curtailment doesn't apply, or that it subtracts the curtailed power from the total available so that the total power shown is only the power actually transmitted (exported) to the grid? It's very likely that I'm just not familiar enough with the terms, but this wasn't immediately clear. My guess is the former meaning, although I can imagine it meaning either.

Regardless, this is incredibly neat, and I'd love to see this kind of data for the grid that serves me (Eastern Interconnect in the US) -- are you aware of any sites similar?
