Lifetimes of money, really? What is that measurement? Someone above said 2.5 million per square miles. Catastrophic damage from larger storms is often in the tens to hundreds of billions of dollars, so it feel like it would be in the best interest of most parties to embark on this project, even if it happens slowly.



The poster above misstated the cost. Its $2.5mil/mile. That number actually comes from PG&E in California, so its possibly not relevant to Houston. I couldn’t find that Centerpoint has actually done an analysis for Houston. Just to get an idea of scale, Centerpoint states on their website that they operate ~33,000 miles of above ground power lines.

Putting power lines underground wouldn't mitigate very much of that damage though, would it? I was under the impression that the vast majority of those multibillion dollar figures is water damage to buildings, cars, and other equipment.


Just one anecdote. We lived through the deracho in Iowa, one of the places hardest hit. Huge swaths of the city was without power for weeks. In our house, in the middle of the most damage, was without power for under 24 hours. That's a massive difference. I don't know how much the calculations take into account physical damage versus all up damage including lost productivity. But many of the folks working at the local company were back "in the office" working from home because the business was without power far longer than most of the employees. I have no idea how the overall damages are calculated.


A lifetime of money is ~$10M or so. That's $100k/year for 100 years.
