NERC and Data Center Grid Reliability
Coverage from Keentel Engineering, Carbon Direct, and others
Large data centers and other computational facilities can place substantial, fast-changing loads on the bulk power system.
NERC’s alerts and guidance focus on improving the information and studies used to represent these facilities, including their protection and control behavior, interconnection, commissioning, and response to grid disturbances. A Virginia transmission fault in 2024, during which many data centers reportedly disconnected nearly together, illustrates why coordinated load behavior matters to grid operators. The subject also includes demand flexibility and a prospective standards pathway, with FERC relevant to the development of potential mandatory requirements.
