Generally speaking, you are probably better off stacking instead of using such long exposures anyway.
Have you checked the value with the lens removed?
Does the camera still have activities like on Live View (getting data from the senor)?
AFAIK you have exnernal power supply.
Why do not you measure current consumption?
Reading out CMOS (and CCD) is destructive, so live view definitely isn't being updated during exposure.
Yes of course, but what happens in the time between the next shoot?
Generally, CHDK set_lcd_display does not turn of the sensor, and of course set_backlight just changes the backlight.
You can use the chdkptp live view to see if the sensor was turned off, it will show the last frame
or if your camera has a key that directly turns the display off
If I do this on G1x, then live view stops on chdkptp. But that's what should be done in the waiting time for time-lapse or?
If the interval is slow enough that there is a significant time between shots, this will keep temperature down and save battery.
I don't know what the effect is for scripts like fixedint and rawop that hold down half press ("quick" mode) or full press ("cont") all the time. The "turn display off after ..." setting won't work in this case, but it's possible the camera keeps the sensor on when half press is held on cameras with a display off key too. In cont mode, I would expect the sensor is kept on all the time, but again that's just a guess.
There's so much variation in the canon options it's hard to make a portable script that uses them, although I believe waterwingz "ultimate" covers most https://chdk.setepontos.com/index.php?topic=9969.0
