plants of last resort
These plants will run only at times of low availability from other generation. Knowing when they are running helps indicate times of grid stress and so can be used as a guide to reduce demand.

Capacity Remaining
When in service, it’s interesting to know just how much spare capacity is available from these plants and how much more (or note!) they can offer to the grid.
To Show (off):
Because we can
The main reason this site exists is just “because.”
The data is all in the public domain as to what many plants are outputting, so ultimately, why not use it?
