In the latest Columbia Energy Exchange podcast, I talk with Marcus Sachs, the chief security officer at the North American Electric Reliability Corporation, about recent incidents and what they tell us about the vulnerability of the U.S. grid to cyber attacks.

Marc describes as well as anyone I know the risks that computer hacks pose for the electricity infrastructure and the steps being taken by the power industry and the government to guard against such attacks.

Not surprisingly for someone from the industry, he’s confident in its ability to keep the lights on. But just as significantly, he also makes clear that dealing with such intrusions is no easy task, and one that demands constant vigilance.

Please take a listen to our 30-minute discussion, and let me know what you think.
