I don't know what large DC do but at our large sites we normally get power cheaper in exchange for a load shed agreement. When we got the call we ran some/all of the load on generator so the grid could flatten peaks. At our tv/radio transmitter sites there were no UPS so a break would disruptive. SOP was to run up the gens, sync then parallel the grid. DC just treat it as a power failure with a short break on non UPS service? brandon
