At the end of the day when everyone goes home, the power demand drops to a small fraction, but the local nuclear plant is still squirting the current into the lines (they cannot run reduced or no load) so the power is redirected to lights all over the county, including farm

Here in Virginia, Dominion Energy has a pumped storage station: <https://www.dominionenergy.com/projects-and-facilities/hydroelectric-power-facilities-and-projects/bath-county-pumped-storage-station> At night, power from a nuclear station runs the turbines backward to pump water from a lower reservoir to an upper reservoir. During the day, water flows from the upper reservoir to spin turbines and generate electricity.

Not as efficient as primary power generation (and impossible in flat Illinois), but at least it's not lighting up farm fields.

And boy, is the sky dark in Bath County, Virginia! Been there, looked up. :-)
