A power plant produces megawatt-hours, a customer uses megawatt-hours, and the bill follows. That mental model is useful but incomplete. The grid also needs support jobs that keep electricity usable while it is being produced and consumed. Frequency has to stay close to its target. Voltage has to remain within workable limits. Reserves have to stand ready. Ramps have to be covered. Faults have to be isolated. After a blackout, parts of the system need the ability to restart. These support jobs are called ancillary services, but there is nothing secondary about them.</p>
