Electrical Substation Attack in North Carolina—What Happened?

Here is more on the Moore County substation attack on 2022-12-03 in North Carolina. Oil-filled radiators on two step-down transformers were damaged by gunfire, resulting in their disconnection from the grid and loss of electrical power to around 45,000 customers of Duke Energy for up to four days. A second distribution substation was also attacked, but as it was downstream from the main substation, did not cause additional loss of power.

To date, the perpetrators and their motive(s) have not been identified.
