OK here we go
I have property up state with no power, the nearest pole is appx 1800ft+ away from where I am going to put a summer house the electric company states it will cost me $25000.00 for poles labour and parts. This is insane.

My question is if they put a pole with power on the edge of my property with a meter and box how far can I run over or under ground wire for a 200 amp service to the house and what size wire will I need
The run would be appx 1200ft is this possibly or what are my options.

Sounds like CMP in Maine.

A 1200 foot run is not practical for delivering 120/240 volts.

Something like this needs to be high voltage for most of the run with a transformer much closer to the house, like 50 feet away.

Isn't utility de-regulation fun?

Try for a local electrical contractor that specializes in or also does pole line or underground high voltage power lines. I am sure there is a couple in your area.

If you can do the trenching or get this done reasonable, UG would be best, instead of poles.

If it is Maine, besides my company, there are several that can handle this installation.

Doing the trenching would not be a problem as I have a bobcat with a backhoe attachment
And I am not opposed to working my butt off.
What size high voltage wire would I need and where can I get it and a transformer
I would also need a pro to hook it up after the wire is in the trench
Would going this route save me enough money.
And how deep does high voltage line get buried
The property is in (ephratah (fulton countyNY)

Need to consult with the utility for the voltage that have on the street, can be anywhere from 4160 volts up to 13,800 volts, possibly more depending on how rural you are.

This will rate the cable you need.

Here is a typical cable, #2 Al for up to 15Kv.

Okonite Okoguard® URO 15kV Underground Primary Distribution Cable Aluminum Conductor/90°C Rating 133% Insulation Level

Up to 22Kv direct buried cable needs to be a minimum of 30 inch deep, typically with 6 " of dead sand below, and above, with a warning tape 12 " below grade the entire length of the run.

A typical transformer can be a 50 KVA:

Depending on soil conditions or if you want extra protection, you may want to consider using a 4" PVC DB conduit to sleeve the cable for that distance.

The transformer needs to sit on a pad, which can be precast concrete, or there is even composite/fibreglass ones available.

A pro certainly will be needed to terminate the High Voltage cable.

Steel conduit will probably be required as a riser at the utility pole.

Here is a list of electrical contractors in Fulton County;

You may need to look in the Albany area for someone that does do high voltage work.

Hello!

I'm dealing with CMP now... :( I only have 500 to 700 ft to reach a pole, depending on whether a gully can be crossed, but CMP is quite outrageous. It is a new place, so this needs to get done for temporary service before serious construction can begin.

You do this kind of work in Maine? If you are interested in work in N.Bridgton, send me an e-mail. Include your phone number, and we'll talk. If you are not interested, I would appreciate any suggestions. We need this done ASAP.

I could use an affordable option. CMP isn't going to offer one.

Thanks!

Bob

I sent an email a few days ago, did you receive it?

While CMP does charge for all connections, simple connections are usually very reasonable. Line extensions, such as yours, can be costly, but CMP is not in the business to be competitive.

While we do Medium and High Voltage installations,we do not do single residential lines. Only utility substations, industrial feeders, etc.

If you have an electrical contractor for the home, while he may not do line extensions, he can hire another contractor that does. He can purchase and install the MV cable in the trench, and hire someone to do the connections. Or , if a pole line extension he can have the poles installed and have the aerial cable hung and connected.

CMP can furnish and install the pole or ground mounted transformer, for a fee, of course.

Keep in mind, any equipment that you furnish and install will be maintained by you, at your cost. CMP can effect repairs, when needed, for a fee.

The brook can be crossed using Directional Boring method, but this may be cost prohibitive, and not be a savings over the extra 200 feet. Something to think about and get pricing to compare the two routes and methods.

Consult with CATV and telephone utilities also, as each has their own requirements for both overhead and underground extensions.
