T.O.U. meter

[KhunLA 11860]

Not exactly alternative energy, but usually a topic with EVs & charging overnight.

 

First, applies to PEA, Amphur Muang, Prachuap Khiri Khan (PKK) ... YMMV

... digital meters, are only that, digital display.  Useless for anything else, and not  T.O.U. meter (combo)

... for PKK ... ALL new (& replaced) meters are, will be digital.

... ฿4000+ for installation of a TOU Meter

... along with silly monthly service charge (฿300+)

... 1+ month Q for install ... maybe.

 

Wife has a fact sheet, if much different, I'll edit.  Popped in to pay our 2kW/unit PEA bill, so she asked about TOU meter.

Came out with info sheet and from memory, posted.  She did say they need to install a new meter, which I though silly, we have a digital, surely it does both.

 

She goes back in and told ... NO.  Meter doesn't do a damn thing extra, useful.   Quite the surprise actually, as you'd think it would have a chipset, memory, and different programs for different uses.  

 

Obviously we won't be getting as totally silly.  Unless using a lot of electric overnight, would be hard, impossible for us to get any return from the 4000+ along with a 300+ service fee.   Solar & granny charger is fine (free) for the EV.  Even the 'Wall Charger' if used 0-100% would only be ฿250 ish on present meter.  TOU Monthly servie charge ฿300+.   So paying 300+ to save ฿125 (1/2 overnight rate) ... hmm ... NO THANKS

 

IF considering solar on/off/hybrid ... expect to get a digital meter vs one that will backspin.

IF you don't, kudos for you, but don't bet on it getting a non digital meter.

PEA "were" doing a special offer of a second 15/45 with TOU as a specific meter for charging your EV. But I have no specifics of costs etc. etc.

 

Right now, I would advise anyone going solar to get a hybrid inverter that can export and if you have a conventional disc meter that will go backwards just keep it.

 

If PEA then come along with an electronic meter simply go to no-export and add energy-storage as and when you can afford it.

 

Note that the digital meter really CAN do TOU / export / whatever, it's just that our friends either don't know or can't be bothered to re-program and simply say "need a new meter" (collect charge for same).

 

Way back when we got our "permanent" meter to replace our "construction" meter, having paid for a "new" meter they simply read the existing one! We still have the same meter as we got on day-one of construction back in 2011.

this guy (in the video) had to pay only 46.16 baht for the service charge (bill 12/2022).

when using the TOU meter, you must also add FT, which is presently 0.9343 baht (2.6369 + FT = 3.5712 baht/unit)!

 

I'm hoping to purchase an electric vehicle this year, at which point I'll contact the PEA for additional details.

Not getting my head around the benefit of TOU meter.

 

We'll hit 700kWh this month (have already), and if say 500 was peak, and charge EV on off peak rate @ say 200 kWh, then it seems to be more expensive than our 'regular' meter.

 

[Crossy 42827]

You need to use a lot more off-peak (and correspondingly less on-peak) to get to the break-even point.

 

If you can get a separate TOU meter just for the car and only charge at night you get the best of both worlds. PEA were certainly offering this in the past.

This is the PEA calculator, it's not perfect but ...
