That's a great point about the controls. Originally the map only showed wind farms and as I've expanded the features the control system (and really the entire UX) hasn't kept up. I need to sit down and have a proper think about how best to design the controls and documentation.
Would be nice to have a definition of 'Turn-up' and 'Curtailment' in that FAQ for us non grid savvy visitors.
Works great though, well done.
