ERTH’s MSP Program

Key parts of our program include:

  • Independent Electric System Operator (IESO) application and registration
  • Register, design, install and maintain IESO wholesale electricity market metering equipment
  • Monthly MSP maintenance
  • Responding to Meter Trouble Calls (MTRs) on behalf of our customers
  • Installations including Hydro One Retail Electricity Market metering


Not only were we the first registered MSP with the IESO, but our metering experts provide customers with peace of mind by offering on-site maintenance, repair and re-calibrations while ensuring the job is done right the first time. For customers just starting on a project, we can visit your site to evaluate the design of your location and identify your metering needs and help you determine and obtain the correct meters for your site.

In addition to our MSP services, ERTH is the ONLY MSP in Ontario that holds an Accreditation License with Measurement Canada and operates a diverse water meter testing facility. ERTH is truly a one-stop shop for all metering needs.

Utility Experts

ERTH is in a unique position as we have our own affiliate local distribution company (LDC), ERTH Power. Because of this affiliation we have an in-house MV90 system and our MSP division manages 17 meter points on ERTH Powers’ behalf. ERTH’s metering experts will interrogate, store, validate and estimate data as per the Market Rules. Through this work, we understand what works best for the utility industry and have gained valuable experience and knowledge that we in turn provide our customers.
