Electricity Sub-metering

Why sub-meter?

According to Enercare’s analysis, tenant usage can make up to 70% of electricity consumption in a building and electricity costs are one of the highest expenses for building owners. Ontario Energy Board (OEB) set electricity prices have increased by approximately 50% since 2011.

Sub-metering electricity use is an effective way for individual residents and building owners to curb unnecessary electricity use, as individual units become responsible for the energy they consume in a fair and transparent manner.

Sub-metering works by connecting meters to the main electrical room in buildings, and measuring the use (and therefore cost) of the each unit’s consumption. These meters communicate with Enercare’s in-house billing centres via various communication networks (phone/internet) that collect and collate this data, producing concise billing for residents and various reports for owners to view usage details.

Sub-metering electricity results in benefits for individual residents, those responsible for multi-residential buildings and society as a whole. For residents, sub-metering allows individuals to be responsible for the energy they consume; for building owner/operators, this eliminates an unknowable and variable cost each month; and society benefits as sub-metering drives conservation as individuals are financially incentivized to conserve.

Where we install our meters

We install sub-meters in locations that best leverage the building’s main infrastructure (e.g. the electrical, water and heating and cooling systems) and in the most cost-effective manner. Enercare sub-meters continuously measure and record your consumption every 15 minutes, and then automatically transmit your data over your building’s existing electrical wires so there is no need for traditional meter reading. Residents pay only for what they consume, and reap the financial rewards of their conservations efforts themselves.

Our equipment

We use Swiss and Canadian made equipment that are high quality, reliable and long lasting. Our electrical meters are Measurement Canada Approved devices (S-E-O2) and are inspected to meet CSA standards by a local electrical inspector. We also comply with Measurement Canada S-E-O4 which verifies that the meter is installed per Measurement Canada’s guidelines.

Enercare Connections is authorized by Measurement Canada to perform S-E-04 Meter Installation Inspections pursuant to the Electricity and Gas Inspection Act.

Ontario Electricity Rates

Electricity rates

The Ontario Energy Board (OEB) regulates the province’s electricity sector.

Electricity costs differ on a building by building basis. Enercare Connections customers may be charged according to:

  • Regulated Price Plan, Tiered Pricing
  • Hourly Ontario Energy Price
  • Electricity Retail Contract (Fixed Contract) Pricing

Regulated Price Plan, Tiered Pricing

Under Regulated Price Plan (RPP), Tiered Pricing, Enercare customers can use a certain amount of electricity each month at a lower price. If the electricity usage passes the set amount, additional electricity will be charged at the next tier rate. Tiers are different for home and business customers.

Rate Changes and Other Electricity Details

Rate changes

The OEB sets the electricity prices, including tiered pricing rates, twice each year, on May 1 and November 1, calculating rates based on an estimate of how much it will cost to supply the Province with electricity for the next year. The OEB includes factors such as the estimated amount of power needed for the province, types and pricing of different electricity sources, and accuracy of previous projections. Visit the OEB website for details on how electricity prices are set.

Hourly Ontario energy price

Customers can also be charged for electricity based on wholesale pricing called the Hourly Ontario Energy Price (HOEP), also known as spot pricing. HOEP is the average of 12 market-clearing prices in each hour, as calculated by the Independent Electricity System Operator (IESO). Wholesale pricing changes based on a range of factors that influence supply and demand. For more information on wholesale pricing, visit the IESO website. Customers who pay HOEP are also subject to Global Adjustment, as described below.

Electricity retail contract (fixed contract) pricing

If a customer’s building has chosen to buy electricity through an electricity retailer at fixed contract rates, the customer will also be billed using those rates. Electricity retailers are private companies licensed by the Ontario Energy Board. The Ontario Energy Board does not regulate prices offered by these companies. Customers who pay electricity retail rates are also subject to Global Adjustment, as described below.

Global adjustment

Global Adjustment is a charge or credit to customers who pay Hourly Ontario Energy Price or electricity retailer rates. Global Adjustment fluctuates from month to month and covers the cost for providing adequate generating capacity and conservation programs in Ontario. Global Adjustment rates are set by the Independent Electricity System Operator (IESO). Generally speaking, when HOEP is lower, then Global Adjustment is higher in order to cover additional costs.
