New electricity supply. Initially TBS

[flanagaj]

Our electricity supply requirements are not straight forward.  We need to have the pole moved and have agreed a £3k contribution to have it moved to the boundary, but have been advised it can take 12 months.  We obviously do not want to wait 12 months before we commence development and therefore require a TBS, so that we can get started and have a mobile home on site.  I am not sure how many KVa we need for the house (we are having to spec ASHP, EV chargers).  There is no mains gas.

 But obviously, the TBS can be much less.  What do people recommend here.   Generator for the mobile home or have a TBS put in, but will need to be eventually moved when they move the pole?

BTW these subjects have all been covered multiple times and you’ll learn a lot by searching out old replies. In short:

 

+ install a kiosk once and then you can route from there later without intervention by the dno. A temporary generator can also be linked into the kiosk if you want.

+ the power requirement is just a book exercise (sensible answers will be about 12 kVA) i.e. 50A-60A. That is, HP + EV + a bit for the rest. Not even sure why they bother to ask this, unless it’s to get you to think (for yourself) how much power you’ll be using max.

+ in practice, whatever you ask for, there are only a few options actually delivered by the DNO - 100A single phase, 63A 3 phase and maybe a derated 80A or 63A single phase if your local network is very near max load. You may not get the option of 3 phase.

+ use your social engineering skills to ask the rep on site in informal conversation what the actual timing for a pole is.

+ get this all rolling asap - leccy seems to be by far the slowest of the utilities.

 

p.s. this is a bizarre corporate game where they present you with something that looks like an al-la-carte menu, knowing full well that they only have one dish that they’re prepared to serve you. Save some bumps and ask informally what’s actually available and ask for that.

Have a kiosk to get going, a gent is a ballache and you won’t have WiFi / cctv / security lighting capabilities overnight without proper juice.

 

If that can stay put long term then great, but if not you’re only really liking at the fee for a “service alteration” when (if) you want to migrate the service head into the dwelling. 
 

For the immediate purpose, also ask for the price of a downstream service alteration so you have the costs in your possession to make a robust decision at this time.
