Submetering in Alectra Utilities Territory

Alectra Utilities Corporation is one of the largest municipally owned electric utilities in Canada, serving approximately one million customers across a large portion of the Greater Toronto and Hamilton Area. Service areas include Mississauga, Brampton, Hamilton, Vaughan, Markham, St. Catharines, and several other municipalities.

Buildings in Alectra territory that adopt submetering follow the same OEB framework as all Ontario buildings. Delivery charges from Alectra are passed through with no markup. The USMP's service charge is separate and clearly disclosed.

The GTA is one of the fastest-growing regions in Canada, with significant multi-residential construction activity. New condominium and rental buildings in Alectra territory can incorporate submetering into their design from day one, which simplifies installation and reduces costs.

For existing buildings in Alectra territory, retrofit submetering is a well-established practice. Many older apartment buildings in Mississauga, Brampton, and Hamilton have successfully transitioned from bulk metering to suite-level billing.

Alectra's rate structure includes distribution, transmission, and regulatory charges similar to other Ontario utilities. The specific rates are set through the OEB's rate-setting process. Residents in submetered buildings see these charges as separate line items on their bills.

The rapid growth in municipalities like Brampton and Vaughan means many new multi-residential developments are being planned. Developers in these areas should consider submetering early in the design process. Incorporating metering into the initial electrical design avoids the complexity and cost of a future retrofit.

Property managers in Alectra territory have access to the same conservation programs and bill assistance options as other Ontario customers, including OESP and LEAP.
