MDMA vendors say commercial submetering can save fleets; NEM exclusion and certification costs hinder wider adoption

Summary

Meter data management agents and charge‑management vendors told the CPUC workshop that submetering offers meaningful savings for commercial and fleet customers but that the CPUC decision’s exclusion of net energy metering customers, high certification/sampling costs and uncertain MDMA revenue models are blocking scale.

MDMA representatives and commercial charge‑management vendors described use cases where submetering delivers clear value for fleet, workplace and commercial hosts, but warned that policy and certification choices are shrinking the feasible market.

“Customers want to be able to reduce their electricity costs,” said Zack Lee, director of research and development at PowerFlex, which manages large, commercial charging portfolios. Lee presented portfolio examples showing annual energy‑cost savings of about $72,000 (roughly 65%) for a workplace customer and about $55,000 for a fleet customer. He argued these savings create a commercial case for submetering at medium and large sites and suggested MDMA business models should route a large share of the per‑kilowatt‑hour benefit to drivers while preserving a portion…
