Working on a project where two spaces with separate meters (2 tenants) now becomes one space (1 tenant).

It would obviously be much cheaper to leave the electrical distribution as is and keep the 2 meters to the now single space.

Question is, is this code compliant?


Thank you

Need more info. Are their two electric utility service conductors each meter or are they feeders each meter? What voltage phase size of each conductor in meter? Are the panelboards feeding meters grouped?
 
Likely a call for your local AHJ.
It's an accepted practice here especially in "mall" type occupancy where tenant spaces are combined.
(Here it is required that each plaques be placed at each panel showing the location of all panels for that occupancy)
 
I don't believe it is an issue but they are paying a commercial rate on the meters and they will be a monthly charge for the extra meter
 
It would certainly depend if the tenant space is considered separate building or not. If its separate building then rules of 230 or 225 only one allowed come into play

Are you meaning one service? If so there can be 2 meters and one service. What article section are you thinking?

I am saying OP needs to give more info as to how tow meters are being fed and if tenant space is considered separate building or not. You can have or you cannot have more than one service depending how this is being fed distributed. 230 or 225 needs to be checked based on more info.
 
If the installation was compliant originally, the simple fact that the same tenant is renting both units changes nothing.
If physical changes have also been made (knocking out a common wall, for example) further evaluation is necessary. OP states “becomes one space”. We need to know what that really entails.
 
There might be a cheap way to do this. It would depend on the calculated load of the single tenant but you might be able to run everything off of a single meter and just have the poco blank off the other meter and move the feeder from the blanked off meter to parallel the feeder from the active meter.

Nothing wrong with this.....unless.....each space had its own service disconnect per 230.40 ex#1, and then was converted to a single occupancy because now you have ungrouped disconnects.
 
I drew a little sketch to hopefully clarify a little.

Thanks for your responses. It sounds to me like keeping 2 meters to one tenant is not a problem.
