yun9999 how much did it cost to upgrade from your original 150amp service to 550 ? I am trying to upgrade from 200amps to 400amps and got a quote of $11K. Also in Texas.
How are you able to get a second meter ? I called Centerpoint and they said there is no way a residential house can have a second electrical meter.
Centerpoint is a pain in the ass to deal with. I just finished my service upgrade from a 100A to a 400A on my house. Back and forth on possible solutions. At first they said it was not possible, then they later said it was ok to have a separate meter (would have to be business). However, the transformer in my neighbor's yard had NO spare connections. I wanted a dedicated 400A service to my shed, but they wouldn't allow because there was not enough space to terminate new wires.
So, literally today, my shed was powered up. 400A service to the home through a new 100 foot run of 2 1/2" conduit, buried 20" below grade. However, they have the 80% rule, so i really only have 320A. My home now ties into that service, on a 100A panel (no changes), then we have a 225A disconnect that feeds power back to the shed's dedicated breaker panel.
11K seems high when you already have 200amp
You can have a separate meter on a detached garage or separate building on your property, I did it an added 600amps to my garage and on top of that i set it up using business info so i got far lower business rates on the seccond meter
all for 13k for 600amp
My original estimate was like 10k including digging, but that was before Centerpoint started making problems. I would expect closer to 12k.
For me the biggest cost was the digging crew.
Damn Man! I had a new 200 amp service set for my new storage building. I had $500 in parts to build the service(6x6 post, 200 amp box w/main for outdoor and 200 amp panel for inside, ground rod, conduit and a few other items.) Im figuring about $100 dollars for the wire to feed the shed as thats the last thing i need to have it all finished. Entergy dropped overhead service 150 feet for free. I should have less than 1000 bucks. I was gonna go underground but he told me 3.10 per foot plus some other fees and i had to dig and put the conduit in. .....I was like is there another way? He said yeah we can go overhead for no charge to you!
