An energy subcommittee held a hearing Friday in response to the December Moore County substation attacks.

A person who is injured or whose property is damaged by a utility attack could sue the perpetrator to cover the cost of related expenses. Senators adopted an amendment on Tuesday to lift a cap on the punitive damages someone may seek.

Duke Energy says it has begun improving security around its substations after the December attacks in Moore County and is looking for long-term solutions to a growing problem.

The recent attacks in Moore County, North Carolina, and others in Washington, Oregon, South Carolina and Nevada, have underscored the vulnerability of the nation's far-flung electrical grid, which security experts have long warned could be a target for domestic extremists.

Two power substations were damaged in early December, knocking out power for tens of thousands. The latest shooting did not cause any outages, the utility said.

Federal energy regulators on Thursday ordered a study to determine if security standards need to be improved following recent attacks on electrical facilities, including one in North Carolina.

Ten days after two electrical substations in central North Carolina were knocked out by gunfire, there are still more questions than answers about the incident. The outage left about 45,000 customers without power, some for as long as five days

Duke Energy officials faced questions from state utility regulators in Raleigh on Monday about the Dec. 3 attack on two electrical substations in Moore County. Three Duke executives offered few new details and still aren't saying publicly what the attack might cost customers.

Someone fired shots near a Duke Energy hydroelectric dam in South Carolina on Wednesday afternoon, but nobody was hurt and there were no damages.

Is it simple vandalism or something darker? That’s still the question about the shootings at two Moore County substations that left thousands without power. WFAE’s Tommy Tomlinson, in his "On My Mind" commentary, says it’s natural these days to think the worst.
