i have a similar question on the use of electrical meters,  from the 
doe22vol3-topics.pdf file, page 331 (by pagen umber, or by the (page 333 
of 387), this is the pertinent text:

"This capability is now extended by adding the ELEC-METER command that 
allows you to define up to *25* meters to which electrical equipment can 
be attached. In addition, the concept of "meter levels" is added; this 
allows you to define sub- metering of usage and demand."

i note below the limit is listed as:     ELEC-METER          100
where does this come from?

i have tried creating a building meter, created/assigned 44 submeters to 
it, and then not had any of the meters over 25 report any electrical 
consumption.

is the limit 100 building meters assigned to a utility and each meter 
can then only have 25 sub-meters attached to it?
