I see these gates done all the time, and they just stick a meter behind a bush...

"Electricity is actually made up of extremely tiny particles called electrons, that you cannot see with the naked eye unless you have been drinking."
2-2-4 URD is about 1.25 per foot. I don't have price for 2-2-2 which really is what should probably be run since upsizing ungrounded for voltage drop the EGC would likely need to be #2 also.
Based on 2-2-4 price that is about $2125.00 for conductors alone plus you still need to bury it. If in area where subject to rodent activity it is highly recommended to put it in a raceway.
I would opt for battery and solar charger myself - even knowing batteries will need replaced every 3 or 4 years minimum if there wasn't anything else needing power that couldn't be run from the batteries anyway.
I assume a drive 1700' is similar to ours in that the 7200v from the street is taken to a 7200->240 xfmr within 200' of the house, so to just add a meter behind a bush includes installation of a step down xfmr from power company and a min monthly bill that around here is around $ 50 so really not an option.
I am a huge fan of keeping things simple, especially for a dwelling unit.
We do a fair bit of work in supplying UPS systems mostly in the 10kVA to 400kVA range.
In truth, we don't make any of the parts. We just do the system design and integration.
Mostly, the batteries are Yuasa VLRA (valve regulated lead acid) 10 year life.
They are maintenance free. The electrolyte is gel so doesn't spill even if the case gets damaged.
I looked into that in some detail when trying to get permission to air-freight a consignment.*
On that basis, I'm inclined to think that battery maintenance is not a big issue.
*From the manufacturer's data sheet:
Special Provision A67, contained in IATA Dangerous Goods Regulations and the ICAO publication, Technical Instructions for the Safe Transport of Goods by Air and states that:
"Non-spillable batteries are not subject to these Instructions if, at temperature of 55C, the electrolyte will not flow from a ruptured or cracked case and there is no free liquid to flow and if, when packaged for transport, the terminals are protected from short circuit."
