Also, BURY. THE. DAMN. LINES.
This would be monumentally expensive and probably not even realistic logistically. Are you talking all or most lines in the Houston metro and surrounding areas?
Sorry, you're getting a long answer but I'm fired up on this subject.
Yes, it would be expensive. But there have been how many of these multi-day to multi-week outages over the last 10 years? These will not stop and as the region grows the customer base and scale of outages is only going to get worse unless something fundamental changes with the infrastructure.
This is an entire conversation unto itself, but my $0.02 would be something like this:
- High power transmission lines stay above ground. It would be a major cost to move these underground and no real reason to since most are out of reach of trees. There are still transmission lines across the city which, unbelievably, are on wooden poles. Modernize these select lines to concrete or steel poles and raise the heights to 60+ ft above street level.
- Any time a road is being renovated, bury the overhead lines. Houston already has a practice of updating the storm sewer system and transitioning old asphalt to concrete paving when roads are renovated. Memorial Drive and Shepherd/Durham are recent examples where there was a phased approach to tear out the entire roadway and upgrade infrastructure. These are major thoroughfares and supply utility access to whole sections of the city - it warrants hardening infrastructure beyond just the wet utilities.
- Review major corridors' distribution lines and create a 10-year plan to move distribution lines underground, in conjunction with or absent any other road construction.
- Review neighborhoods which have existing underground electrical but are connected to the grid with overhead distribution lines - create a phasing plan to move these intermediate sections underground.
- Change the design standards for all new commercial developments and residential subdivisions to require underground distribution facilities. Disallow any new poles to be installed moving forward. (I'm a commercial developer - this would affect my industry directly, but we are equipped to handle costs like this more so than John Q. Public can when building a new one-off house).
- The City already requires ROW dedications or upgrades when new development warrants it - deeding additional land for continuous width ROW corridors, road paving upgrades, new medians, new signalization, etc. This is an established process on the books and there are even mechanisms in place for developers to recapture costs after fronting the initial construction expenses. Expand this to move distribution lines underground.
- TX Legislature creates legislation that (1) allows MUD's not already empowered with electrical utility powers to universally have right to install and (2) forms a coordinating agency between private utility providers and municipalities / MUDs that is also empowered to set minimum design standards on new construction. Give the people living in MUD's the opportunity to vote on installing underground facilities rather than live with whatever the original developer installed.
- The real kicker: transitioning the distribution lines in existing neighborhoods underground. This is necessarily a long-term project done over probably two or three decades and bonded out with proceeds from rate increases. I do not know how it could be done fairly or evenly across such a large metro as Houston, but one idea would be splitting the metro service areas into differential zones such that a rate hike only takes effect when infrastructure in that zone is scheduled to be replaced - the idea being to pair up cost levies with when new facilities are actually delivered, not just a blanket rate hike city-wide when it would take 20+ years to do the upgrades.
Edit to add: I had no idea centerpoint reportedly turned a $6 billion profit in 2023. Screw rate hikes - there's your funding for this stuff. The whole of the I-45 / I-10 / I-69 renovation around downtown is supposed to cost $11 billion, or two years of CNP profit. That is freaking insane and maddening.
