What is your home's voltage today (07/02/2026)?

[ripcord]

I just saw that CNBC is reporting that PJM may have to cut power to some customers to protect the grid. What's your current voltage (and general area) today? Here at my house in the greater Seattle area, it's varying from 119.1V to 119.6V. I don't ever remember seeing it move around that much and we're not even in the middle of the heatwave..

116.4, coming down off a mega heat wave.

Mine hovers around 125v. It drives me nuts because my dehumidifiers shut off and trip an overvoltage code. Also, I run my antique radios, which are designed for 110v.

before some work my voltage would go from 105-130 or so.

its been mostly 117-125 recently.. although it hit 109 the other day for an hour or 2 ( not even during the heatwave)
I have this nifty TING device.

The ting sensor is plugged into my panel outlet (outlet 6" from my breaker panel on separate breaker)

so while not immune to being influenced by electrical use in the house its fairly isolated from when you turn on the microwave or 1500w coffee pot etc.

Yellow arrow is current voltage with the bracketing arrows the low and high voltage over last 24 hours.

Then we have the historic graphs.

Just checked at work.
Single Phase is between 119-121v
3 Phase clocking in at rock steady 208v

I imagine my home is similar.

 

[walterjay]

118.8 at the moment

 

[Pablo]

241 and 120 at the side for my PC UPS

IT is quite odd because we almost always run 122-123

I'm thinking we must be sending a whole bunch of power to parts east. I saw PJM had been paying $2000 per kwh for additional power on the market.

probably MWh

 

[ripcord]

probably MWh

Yes, you're right. Wrong order of magnitude.

 

[skyactiv]

I'm at 117.3

 

[Lubener]

Right now at 120.4 v.

Its not the voltage it's the frequency.
Drop below 59.6hz and the clocks start ticking. They have 20 minutes to increase frequency or power plants start disconnecting from the grid.
They auto disconnect at 59.4hz.
Voltage is the easy part.

You have 208 3 phase at your residence?

 

[DCDG]

My home is very consistent between 120-122v even seen 123v when grid usage is low

So voltage doesn't sag during extreme loads? Not arguing, just wondering?

When it sags enough you get a brownout.

It can but voltage doesn't disconnect power plants to disconnect from the grid.
My voltage is probably right around 125v.

120V.
