The grid tells you first. Somebody has to be reading.
The operation
A balancing authority runs on margin that moves by the hour: load against generation, transmission against weather, a reserve number that looks fine right up until it doesn't. The signal that the margin is closing exists before the margin closes. It is usually sitting in a channel nobody is watching at three in the morning.
The read
Every channel against its own limit.
The filled wedge is the channel now. The dotted line is where it is heading. Red is the point it breaks, and nothing else on this instrument is ever red.

Zone names and grain are the real NYISO arena. The readings shown are modeled for demonstration, not a live system read.
What changes
Forge reads that margin and projects it forward, so a closing reserve arrives as a call with odds on it instead of an alarm after the fact.
Tested here
Tested on EIA-930 across 37 balancing authorities at hourly grain. Floor skill of +30.4 to +61.0% over persistence at the measured lag, and breach-risk Brier of 0.005 to 0.030 against climatology's 0.033. Gates written before the data was opened.
