Planning for submetering a large facility (no matter what vendor you ultimately choose):
Begin with the largest single building.
Identify and label every service panel and all who are served. Take detailed photos and notes.
Identify what specific circuits will be metered and who they serve (tenant) in each panel.

Review appropriate equipment for the job and compare features and price.
Obtain qualified/licensed installers who will understand the material before they start.
mM uses one processing unit to monitor multiple independent circuits in a panel.
This costs roughly $75 for each "virtual" meter.
This includes all software, source code, and unlimited technical support.
Emergency/barebones data collection can simply be a visit to each processor with a generic laptop.
Desktop data collection exercise with the first processor is strongly recommended.
