Pea Smart Meter

[JAN]

 

Wonder if anybody can tell me how to read the PEA smart meter.

 

It has 3 different rates:

T1, being peak rate (9AM till 10 PM)

T2, being off-peak rate (10 PM till 9 AM)

T3, being weekend rate.

 

Anybody knows what are the charges in Thai Baht for each rate?

 

What does L1, L2 and L3 mean?

 

And then the different displays, especially which display tells me the current meter reading, e.g. how many KW used in total?

 

A bit confusing, I must say????

L1L2L3 Part.

You have a three phase supply (like me).

Most people have a one phase supply.

A one phase supply has 2 incoming wires L1 and common or neutral.

A three phase supply has 4 incoming wires L1, L2, L3 and common or neutral.

Have you actually signed up for TOU (Time Of Use) metering, if so: -

You will be 1.2.2, weekend is the same rate as off-peak.

I like the totally secure twisted wire deterrent on the reset button.

Indeed, had noticed that as well. What will happen if I press "reset" ????

I had a look at the link. Apologies but how would one know what voltage level would apply?

Potentially it looks like if most of your usage is overnight and enough of it, it could be a good deal if available? 

I know I would need to calculate based on usage.

You are, as I noted, 1.2.2, lower than 22kV, unless you have a private transformer. But you can check easily coz your bill will tell you (just look at the standing charge).

Ahhh, thanks, did not think of that.

Yeah, our daytime usage is pretty well zero due to us having hybrid grid-tie solar, so if we get an electronic meter I think we will go TOU. At present we have a spinning disc meter that goes backwards if we export excess solar energy.

Usually they come with lead 'seal' that's tamper evident

Those lead seals are still quite easy to tamper with.

Just wondering if:

 

1. This would be of good benefit (reduced electricity bill) if recharging an EV battery at night time?

 

2. Would this bring substantial bill reduction for a house which uses 3 or 4 air-conditioners most nights?

 

Thanks.

1. Possibly, 2. Probably not.

But you would have to do the sums particularly the relative consumption between peak and off-peak times.

 

BUT

 

PEA have (or at least had) a policy whereby if you had an EV you could get a second meter (which could be TOU) so you could charge on cheap energy during the off-peak times, this definitely would save you $$$ because your normal consumption would remain on your existing meter.

 

You should talk to your local PEA office to check what deals are available.

I had been charging my Tesla at night during offpeak and it worked out very well to justify the hit for air conditioning during the day. But now I have PV panels so electricity is free during the day and cheap at night (if I even need it).

We have a substantial solar installation so our daytime load is covered by that.

 

I went to a PEA office to ask about converting our 3 phase supply to TOU rates. I was at the Hang Dong PEA office but was told that I had to go the Chiang Mai office.  I was also told that there would be a charge of 5714฿ for the rate switch.   We already have a digital smart meter so I'm wondering why such a high charge.

Maybe it would involve a new meter.

I bought an additional meter ( TOU ) for charging only my EV and it was around 4,800 baht, your extra charge ( 5714 baht ) could be the 3 phase aspect.

It "should" just need a re-program of the meter, but you can bet they won't do that on-site so a meter swap it will likely be 😞 

 

Were the PEA chaps aware that you already had a digital meter? Maybe they were pricing for a replacement of a spinning-disc unit.

It was the small office in Hang Dong where I asked.  They're English was limited and my Thai nonexistant so clarity probably suffered.  I did tell them that we had solar installed and a digital meter.
