JAN Posted August 19, 2023 Share Posted August 19, 2023 (edited) 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????

carlyai Posted August 19, 2023 Share Posted August 19, 2023 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. 1 Link to comment Share on other sites More sharing options...
Crossy Posted August 19, 2023 Share Posted August 19, 2023 Have you actually signed up for TOU (Time Of Use) metering, if so: - https://www.pea.co.th/Portals/1/Knowledge PEA/Electricity Tariffs JAN66 Unofficial Translation.pdf?ver=2023-01-27-133655-423 You will be 1.2.2, weekend is the same rate as off-peak. 1 Link to comment Share on other sites More sharing options...
RayWright Posted August 19, 2023 Share Posted August 19, 2023 I like the totally secure twisted wire deterrent on the reset button. 1 Link to comment Share on other sites More sharing options...
JAN Posted August 19, 2023 Author Share Posted August 19, 2023 Indeed, had noticed that as well. What will happen if I press "reset" ???? Link to comment Share on other sites More sharing options...

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. 1 Link to comment Share on other sites More sharing options...

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).

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. 1 Link to comment Share on other sites More sharing options...

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. Link to comment Share on other sites More sharing options...

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. Link to comment Share on other sites More sharing options...
