First of all, most stations are not running their digital signal at
reduced power. A few did when they first came on, but since nearly
all TVs sold in the past few years are digital/HDTV sets, it would be
ridiculous for any station to want to run reduced power. Much of
what you have heard about this is simply an urban legend.
As for how much power will be saved, I really don't have any idea of
what is the number. What I can say is the stations that will save
the most will be those that remain on VHF, since VHF requires much
less power than UHF. At this point, nearly all stations (there are
exceptions) have their digital signal on a UHF channel, those
transmitters use a tremendous amount of power. (Again, don't ask me
for a number!) A solid state VHF digital transmitter uses a lot
less power by comparison.
However, this all is a very small amount of the total budget to
operate a TV station, I don't think you'll be seeing any stations
turn off their analog signal early to save on the power bill.
