The draft term is 'computational load'[0], which is the focus of the L3 essential action in that press release.
NERC's concern appears to be computational load cutting. In 2024 for instance, 60 data centers in NoVa cut 1500Mw of load in a matter of seconds[1]. Dominion reported 70GW of large load deliver points, with 40GW in new requests that are 'vast majority' data centers.
40GW is approximately enough to power about 30 million homes (at 1000 kwh/month).
