1:How much (approx)do P.e.a charge to connect electricity to a new house? Main power line about 50 m from house build. 2: Do we have different choices(amp) when install? 3: Our main house today has low power(amp),can the P.e.a up the power by install a moore powerful cable to the house or how would they do? 

SWMBO says we paid 700B, but that was direct from the PEA pole. I guess you might need to put your own poles in first.

PEA only provide the service to the meter, connecting from the meter to your home is your (or your contractor's) problem.

 

Do you already have a "construction supply" (billed at double the normal rate)? How does that get to the house?

 

Most normal homes have a 15/45 supply (45A max, about 10kW) which is adequate for most users.

 

Have you or your builder done a prospective-load calculation? If it comes out as more than 10kW or so you may be looking at a 3-phase supply 😞 

PKK province, Muang, the first 140 meters is free, if needed.   We are 155 meters from the main line, on a mapped soi, but not hard surfaced.    They didn't charge us extra, just spaced the poles out a bit further.  Helps to smile when chit chatting with them.   I guess they charge by poles, every 20 meters.

 

I think each office is different, and guessing there is a 'free limit' ... but ... if they can scam you, then they will.   Udon Thani (2 different districts) had a completely different 'pricing' policy.  Damn expensive if you let them get away with it.

 

Water was a different story, and 50k baht, but it is 'our' line, and any additional houses added to it, need our permission, and we can charge them to hook up to.  We allowed 1 house to use, but won't in the future, for fear of loss pressure.
