A recent Federal Energy Regulatory Commission analysis finds that it would be fairly easy for terrorists to knock out all the electric grids in the US. And not just for a short time, but for about a year and a half!
“Destroy nine interconnection substations and a transformer manufacturer and the entire United States grid would be down for at least 18 months, probably longer,” FERC officials wrote in a memo for a former FERC chair.
John Upton at Grist further summarizes: “Crippling America’s old-fashioned electrical grid for a long period of time would be disturbingly easy. Saboteurs need only wait for a heat wave, and then knock out a factory plus a small number of the 55,000 electric-transmission substations that are scattered throughout the country.”
Oh, but surely these substations are heavily protected, right? Umm…
From a Wall Street Journal article on this story:
In last April’s attack at PG&E Corp.’s Metcalf substation, gunmen shot 17 large transformers over 19 minutes before fleeing in advance of police. The state grid operator was able to avoid any blackouts.
The Metcalf substation sits near a freeway outside San Jose, Calif. Some experts worry that substations farther from cities could face longer attacks because of their distance from police. Many sites aren’t staffed and are protected by little more than chain-link fences and cameras.
Holy yikes!!
Now, I think solar enthusiasts know what one very helpful solution would be. And if you didn’t before, you probably caught it in the title above. It is: a very distributed electricity system. For example, an electricity system that uses a ton of distributed solar power systems (e.g., rooftop solar).
Microgrids would be especially helpful and protecting against any such attacks. High military officials have been telling us this for years.
So, let’s get on it! Let’s install a ton of solar power, and let’s get moving on microgrids of the 21st century.
(By the way, FERC was not too pleased with the Wall Street Journal covering this sensitive topic. But the fact of the matter is: we need to develop a more secure grid, and maybe we need the public to push for that.)
