Hi Ron What I highlighted is: how come someone who claims to have implemented this did not realize that the sleeping power is non-zero? If I draw a dotted line, how does one ensure that the power-saving estimate for a given “power group” is accurate? The questions Robert asked are valid and related. What is the right data model? We need to ask the Green WG.
Also, operators perform many capacity planning exercises to design the network. The operators need to consider what the implications are for shutting a “power group” What considerations must be in place before shutting down the "power groups"? Is this a good idea, or will it create more pain for network operations?

Can you describe such an architecture? Ron
