I see the same thing after every hurricane that hits BR

I know my neighborhood and multiple other neighborhoods who would split the cost with the city so start with those and by next year all wires will be underground

If I had a nickel for every time I’ve heard this, I still wouldn’t be able to cover the cost of doing it


Plus, the transmission wires are always going to be aerial somewhere.


If you want power, for cheap, you have to be able to move that power from the place of production efficiently.

It has to be cheaper than replacing all the lines every few years in a city

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.
The price tag? Somewhere between $15 billion and $30 billion. But the new CEO, Patricia Poppe, told reporters when she made the announcement that doing nothing would cost the company, and the state, even more. “It’s too expensive not to do it. Lives are on the line,” she said.

Nationally, there are 160,000 miles of high-voltage transmission lines and, according to one estimate, 5.5 million miles of local distribution lines. Mike Beehler, national spokesman for the Power Delivery Intelligence Initiative, a trade group advocating the undergrounding, or burying, of lines, says that in most of the country putting a line underground is easier and less expensive than in California. “The cost of underground is coming down,” he said.

Critics say the price is not always justifiable. In an essay for the Conversation, Theodore Kury, the director of energy studies at the University of Florida, argued that in many places overhead lines can be afforded better protection than they now have, for much less money than it would take to bury them. Stronger poles, better anchored, would be one step, he wrote, while aggressive cutting back of vegetation would be another. Getting access to the lines for maintenance could also be problematic, he added. Beehler, in contrast, argues that maintaining exposed overhead lines can cost three to seven times as much as dealing with those in protective sheaths underground.

John Fluharty, vice chair for the Power Delivery Intelligence Initiative, said that while burying transmission lines is more expensive than stringing them through the air, underground lines do not require repairs with every strong storm that passes through, and over the course of their lifetimes can provide cost savings. He pointed out that going underground doesn’t have to be an all-or-nothing proposition: Utilities can pick the stretches where it would make the most sense.
Overhead lines naturally grow hot as they carry current, and they rely on the air to cool off. Operators must constantly monitor the temperatures of high-voltage lines to be sure they are not overheating. Warmer weather linked to climate change can make that more of a challenge, especially as air-conditioning demand also rises and helps to raise the temperature of the lines.
A technical challenge is in making sure underground lines can remain cool in the enclosed space of a conduit. And as Hurricane Sandy made clear when it hit the New York area in 2012, any underground electrical equipment has to be provided with watertight protection against immersion and the resulting corrosion.
