Quickly, what I wrote herein is in regard ti the check meters, or sub-meters that are used for revenue collection from tenants within a structure that has a single utility meter.
'Demand' is the available capacity that the POCO has to have available to provide power. Basically, what Tesla said above.
Also, keep in mind I am in NJ, USA, not my neighbor to the north...Canada. Our electric rates here are probably a lot more than Canada's.
The 'Demand' charges are quite substantial, and IF the bldg owner in the above scenario does NOT install demand sub meters, he will eat the demand charges!
