What it would take to put all our electric lines underground

Unread post by uncledad »

Hurricane Ida plunged more than 1 million customers on the Gulf Coast into darkness, and then knocked out power to another 200,000 in the Northeast on Wednesday night. The chief culprit, especially as the storm first came ashore, was the wind — blowing trees, roofs, signs and assorted other debris into the transmission lines, and, in Bridge City, La., knocking down a major utility tower.

A way to avoid that does exist: burying cables underground. Electric power in Manhattan — where the lights stayed on despite Ida’s floods — has been channeled underground for years, as it has in other downtown areas across the country. Germany and the Netherlands are moving to put all their lines below the surface.

The chief drawback is the expense. In California, Pacific Gas and Electric resisted calls to bury its transmission lines for years as being too costly. But after the company’s equipment sparked a string of devastating forest fires, it reversed itself in July, announcing that it would bury 10,000 miles of lines that currently run overhead.

Dominion Energy, based in Virginia, and WEC Energy Group of Wisconsin are each planning line-burying projects, which will result in a total of 5,000 miles of underground wires at an estimated price tag of about $2 billion. That cost, like the PG&E bill, will be passed along to customers. Dominion expects its project to take 10 to 12 years to complete.

Where I live, all the utilities are underground. It's very rare to lose power. We had a major ice storm years back, whole counties had no power for a weeks.
