This gets into the utility frequency... that information is already out there, on the grid. https://en.wikipedia.org/wiki/Utility_frequency#Frequency_an... and https://en.wikipedia.org/wiki/Dynamic_demand_(electric_power...

The way that power companies "communicate" about load is by slightly changing the frequency.

If the frequency is 60.5, then there's an abundance of energy on the grid and some less profitable generators can cut back or storage systems can charge. If the frequency is 59.5 then there's a lack of available power on the grid and other generators should go on line and unnecessary load should stop doing its thing (and if it has the ability, it could discharge instead).
