    Seems like a loaded question. All the power outages we encounter in Bangkok occur during power storms when a transformer blows - usually once or twice per year for brief intervals.

Dear Folks,

Have you ever wondered why grid-related power outages are extremely rare during evening hours, while PEA workers are asleep?

Yet, they happen all the time while these PEA workers are awake and ON-THE-JOB?

Ever wondered about THIS?

Just an innocent question...and....

Can you, or anyone, provide a good and logical explanation?

Please feel free to chime-in with your thoughts.

Thank you.

Best regards,

Gamma

NOTE: By evening hours, we mean about 7:00pm to 5:30am, in case we need to quantify this further.

just maybe because many of the power outages are intentional they occur when power is turned off to allow the technicians to work on equipment which is not then "live " its for safety reasons . Its not rocket science just standard electricians precautions, I thought somebody of your immense intellect might have considered this obvious explanation

duplicated again AN sort this website out please

One would expect that Thailand snakes might know better.

But, they do not.

Snakes cause a lot of damage, both to themselves, and to the grid.

Most of the power outages where we live in Phuket happen during the day, because that is when PEA is working on the power grid and has to turn off the electricity. We usually receive advance notice from the juristic person at our condo.

Maybe you could check with the PEA or the juristic person where you are staying to find out how you can be notified in advance of any planned power outages.

Yes.

This is why I posed the rhetorical question.

Thank you.

Planned outages have zero relevance to random outages that happped during peak times.

Actually, not completely true.

When the power delivery to one's house fails, and when it is not reported in advance, then, for the home owner and user, the planned outages become random failures, and in fact they are...

Indistinguishable.

random failures are indistinguishable from planned ones.... what <deleted> planet are you on ?

we have 3 phase @ our house, usually 1x every couple of months I hear a transformer blow way down the road

and only 1 side/phase goes out Pea usually out to correct it within 1/2 hour

I encourage members to answer my questions.

However, there is no way that I can actually require them to do so.

If I knew how, then I would make their coherent answers mandatory.

Most daytime outages in Thailand are planned maintenance by the Provincial Electricity Authority (PEA), not unexpected failures. Crews shut power during daylight because it’s safer to work on poles and lines, faults are easier to locate, and it avoids sending workers out at night. Utilities also try to avoid scheduled cuts in the evening when household demand is highest. When power goes out at night it’s usually an unplanned fault (storm damage, equipment failure, vehicles hitting poles, etc.) and those tend to be fixed quickly, so fewer people notice them.

I agree, and the point of the Topic.

Many of these failures are human caused.

The problem is that we are not warned in advance.

And, there are MANY of them.

The workers think absolutely nothing of just shutting down power to a few 10s or 100s of houses, at the drop of a hat.

They do not seem to understand that some users might be using power for critical purposes.

And the service desk never seems to know what the workers are doing in the field.

Still, whether or not these power cuts are intentional or due to an exploding transformer, or often due to snakes, all power cuts are experienced the same way by the customer, left in the dark.

Less demand

Is that actually true for residential areas?

In the evenings, residents return home, and use ACs, and begin charging their vehicles.

Hot-water heaters and TVs are turned on.

Who knows.

It does, more often than during daytime where I live – can I from OP conclude that PEA workers sleep at day in my area...whistling

Sincere question, how do you know for cetrain? The PEA workers are sleeping and probably youtself too. Or are you up all nights to count the outages.

Impossible to sleep when UPS alarms begin going off.

Such a rude awakening.

Sure, didn't think of that one, but then again I have no UPS in my bedroom and why would you leave your UPS on at night?

do you have any evidence to back up your assertion?

at a guess, i'd say offices and shopping malls are closed, so demand is reduced.

I have no evidence from PEA concerning usage comparisons for daytime and evening, or 12pm to 6am.

This was a question.

I was hoping you might provide the data.
