[RE-wrenches] Consolidating meters

[Christopher Warfel]

I used to work for a utility and it is utility dependent. The key I 
think is whether all the submetering customers are actually owned by the 
same entity.  For example, a commercial complex may have several 
building on site, each submetered.  The whole complex could be master 
metered at the service delivery point.  If so, master metering will save 
in several ways, most notably the monthly charge, but demand charges and 
possibly a reduction in the energy charge depending upon the tariff can 
also occur.  The utility should be able to run the analysis for you. I 
would request from the utility the details on master metering at the 
location.  This will quickly get you into their domain/processes. Unless 
you have experience in this area, it can be difficult to calculate the 
cost/benefit.  Chris
