Electricity must be generated at the exact instant it's consumed — it can't be\nmeaningfully stored at grid scale — and the entire grid runs on a knife-edge balance\nof supply and demand that, if lost, cascades into blackouts affecting millions.\nPower plant operation exists to run the machines that produce that electricity\nsafely, reliably, and in precise response to demand, and to keep them synchronized\nwith the grid second by second. The operator controls the plant — boilers, turbines,\ngenerators, reactors, or renewables — monitoring hundreds of parameters, responding\nto changing load, and handling the upsets that, mishandled, damage equipment worth\nhundreds of millions or take down the grid. They are the human keeping enormous,\ndangerous, interconnected machinery in its safe operating envelope around the clock.\nWithout them, the lights go out.
