My voltage starts at around 118V in the morning and drops off to about 113V in the heat of the afternoon. It's a little bit of a brownout, but hasn't seemed to do any damage yet.
I know there’s a heavy load in the triple digit heat we’ve been having in southern Michigan. Everybody is using AC all at once. My electric company is also in the middle of hanging new lines on new poles in the area.
I haven’t noticed the dimming today.
