Given the stress that data centers are already putting on the grid that we all use, enabling these centers to fire up the diesel generators when it suits will just make things worse.  First they'll suck down all available energy, then they'll turn on the diesel and bring pollution and noise to neighboring homes, schools, parks and playgrounds.    Data centers were not placed in cordoned off areas, they've been dropped right in between homes, neighborhoods and recreation areas.   For that reason, it's essential that they not be allowed to add to the nightmare they pose to neighbors by running noisy, polluting diesel generators whenever they'll provide power the centers need.
