I installed an Accuenergy AcuRev 2100 on one of my panels. Used CT's based on the current of the breaker. You can SNMP it, so should be able to do general billing off it. Can do 18 channels. Read every minute, or 30 seconds, and log those. It's a 3 phase unit, and I was retrofitting it

Forrest, Thanks for the suggestion on egauge, that looks like a nice solution and reasonable cost. Trying to do multiple actual utility meters presented some hurdles in needing a PE to stamp a design, township zoning approval (several months), and significant timing issues from the utility who is

Many states require revenue grade metering if you're going to be metering via the kwh. This can get expensive. One option is to calculate what the maximum your customer can draw is based on 80% of the breaker size. And charge based on that. 20A breaker, maximum continuous load of 16A, 16(amps)

Backup generators for sub metering is a PITA. I got permission from the utility to connect the generator ahead of a bank of individual meters on a MTU once. But that meant that my generator was turning the utilities meters during an outage, including the meters on the units we were in. So we

It's flat rate power billing. But thats a good thought to keep in mind. We currently have individual meters installed for the two colo racks but are installing redundant generators and transfer switches, so makes the # of meters double so I'll have like 12 seperate feeds at the start to meter and

Do you have a fixed cost per kwh or is time of use or different cost per kwh based on what bucket your overall usage. You have any other than fixed cost per kwh then just wire everything in the same leased spaces to its own meter. If that retail space ends up being food service do you really

We are remodeling our old office building into a datacenter with 2 or 3 tenants and a 2500 sqft general retail space. I want to be able to sub-meter the power on a per-circuit basis, and ideally be able to assign a group of circuits to each tenant they serve. I have seen some inexpensive solution
