TechCrunch reporting about the grid:

The largest electrical grid in the U.S. has struggled to cope with an onslaught of data centers. Now, after an auction to add more generating capacity fell short, the grid’s operator, PJM Interconnection, has said it will cut off data centers and other large users during power shortages.

Totally reasonable. In fact, the new OpenAI data center in Georgia announced last week has this partially baked in, saying they will “proactively reduce its power consumption before residential customers are impacted during periods of high demand”.
