Electric Submetering Systems for Commercial & Industrial Buildings

We supply the full range: self-powered wireless circuit sensors, branch-circuit monitors, panel-level meters and the current transformers to go with them, from Panoramic Power, Leviton/Obvius VerifEye, AccuEnergy and Fluke. Every meter we sell integrates into one dashboard alongside your water, gas, compressed air, steam and BTU metering, so you are not managing six separate systems.

Every product below has full specifications and a quote request. If you would rather have someone specify the system for you, our AEE-certified CEM engineers will scope it — see meter selection help for electric metering.

Choosing an electric submeter

Four questions decide the specification:

• What are you measuring? A single motor or process load needs a circuit-level sensor. A tenant suite needs a revenue-grade panel meter. A whole distribution board needs branch-circuit monitoring.
• How many circuits? Branch-circuit monitors handle 12 to 96 circuits from one device and cost far less per point than individual meters.
• Can you take a shutdown? Split-core CTs and self-powered wireless sensors install on live conductors during a normal maintenance window. Solid-core CTs require the conductor to be disconnected.
• Where does the data go? Modbus and BACnet integrate into an existing BMS. Cellular and LoRaWAN work where there is no network. See integration components and connectivity.

Electric submetering and energy code compliance

If you are metering because a code requires it, the requirement usually comes from one of these:

• ASHRAE 90.1 Section 8.4.3 requires separate metering by end-use category in buildings over 25,000 sq ft, with 36 months of data retention. Full breakdown of Section 8.4.3
• IECC 2021 carries a submetering mandate for covered buildings. IECC 2021 submetering mandate guide
• IECC 2024 lowers the threshold to 10,000 sq ft. What the 10,000 sq ft threshold changes
• NYC Local Law 88 mandates tenant submetering in buildings over 50,000 sq ft. LL88 tenant submetering deadline

Not sure which applies in your jurisdiction? The state-by-state energy code adoption tracker is updated for 2026, and the compliance hub links directly to the governing documents.

Specifying for MEP engineers

If you are writing the spec rather than buying the hardware, the MEP engineer specification guide covers metering point selection, accuracy classes and data retention language. Manufacturer datasheets are in spec sheets, and our IECC and ASHRAE briefing decks are available in presentations.
