Wholesale Revenue Metering - Meter Exit Program

Hydro One Networks Inc. currently owns most of the wholesale metering installations that measure Metered Market Participants' (MMPs) electricity consumption. Under the Independent Electricity System Operator (IESO) Market Rules, Hydro One Networks Inc. is the transitional meter service provider for these metering installations.

This transitional arrangement ends:

On the earliest seal expiry of a meter or logger forming part of the wholesale revenue metering installation, or
When there is substantial change to the metering installation and/or facility, or
By customer (MMP) choice.

When this transitional arrangement ends, the MMP is essentially exiting from Hydro One Networks' wholesale revenue metering installation.

Initiating the Meter Exit Process

The MMP must initiate the exit process by completing Schedule 1 and choosing a Meter Exit Option that is either inside or outside a Hydro One station. For a detailed description of each option and the accompanying MMP obligations and agreements, click on the Meter Exit Option below that best describes your situation:

Abandon: The MMP is responsible for all market obligations. Hydro One will remove the existing metering installation. Hydro One may allow the MMP to install a new metering installation inside the station.

Use/Upgrade Existing Instrument Transformers (ITs): The MMP will install a new meter inside of the station and continue to use existing Hydro One IT infrastructure until it fails or needs to be replaced. See the process in detail.

De-registration: The MMP decides to de-register from the wholesale market and enter the retail market.

Abandon: The MMP is responsible for all market obligations. Hydro One will remove the existing metering installation.

Purchase: The MMP elects to take over ownership (conveyance) of the meter point. The MMP purchases the metering installation, and selects a Meter Service Provider to service that meter point.

De-registration: The MMP decides to de-register from the wholesale market and enter the retail market.

GENERAL INFORMATION (ANY OPTION)

Market Participant (MP/MMP) Obligations

When the transitional arrangement ends, MMPs have obligations under the Market Rules. View the MMP Obligations under Chapter 6, section 3.2 (PDF 183 KB).

In addition to the above obligations, if a MPs/MMPs existing metering installation is providing Hydro One with Real Time Data for operating purposes, the MP/MMP that is a Transmission Customer of Hydro One, has an obligation under the Transmission System Code to continue to provide this data.

Rebate and Exit Fees

In accordance with the OEB-approved Rate Order [1139F-0:1], when a customer decides on an exit option (except de-registration), they will be charged a one-time Exit Fee of $5,200 plus applicable taxes. An annual Rebate will be calculated from the date the Metered Market Participant (MMP) registers the replacement installation. Rebates shall be calculated by prorating on a monthly basis, taking into account the number of full months during which the meter point is not under the transitional arrangement to a maximum annual amount of $5,700. The meter rebates will cease following the next rate submission in which the metering services will be unbundled from the network tariff.

In order for Hydro One to properly process claims for this rebate, MMPs must fill in a Meter Exit Rebate Claim Form.
