I've been playing around with my Maplin Power & Energy monitor
http://www.maplin.co.uk/Module.aspx?...urce=1&doy=3m8 (I know, I know, I'm a sad person). It seems the Pace set-top box uses almost as much power in stand-by mode as it does when in use.
Stand-by: 23watts 0.13amp
In use: 24watts 0.14amp
Doesn't sound a lot but when you add it up it's 4Kw a week, multiply that by the number of customers...
I've put mine on a separate switch now using a remote control 13A socket.
http://www.maplin.co.uk/Module.aspx?...rce=14&doy=3m8 so it'll only be turned on when needed (I've done the same to the router and modem).
