NERC: Six themes driving grid risk today

As electricity demand rises and the power system grows more complex, six major themes are driving grid risk in 2025, according to the North American Electric Reliability Corporation (NERC):

• New large loads adding demand while the resource mix evolves.
• Reliability events are becoming larger and more widespread.
• Growing interdependence of the gas and power sectors.
• Increasing complexity of cyber and physical security.
• Persistent supply chain challenges.
• “Volatile” energy policy.

“Substantive simultaneous change in all system dimensions (resource, grid, load), along with increasing complexity in the interactions between them, requires rethinking traditional system planning and operating approaches,” the reliability watchdog said in its 2025 “Reliability Risk Priorities” report.
