"Ten years ago we would have this conversation and say, 'What if?' Today ... I think the question is, 'When?'" Curt Hebert, former chair of the Federal Energy Regulatory Commission, and co-chair of the committee that wrote the report, said of a cyber attack on a grid.

More recently, Hurricane Sandy in 2012 pointed out further shortcomings in power delivery recovery efforts. Since then, utilities and other companies with grid assets have been working to strengthen their recovery plans, the report said.
