St. Catharines energy & net metering

What Alectra Utilities charges here, and how surplus solar is credited in Ontario.

UTILITY & RATE
Alectra Utilities
9.8¢-20.3¢/kWh (TOU, OEB RPP)
SOLAR POTENTIAL
Very Good – 1,150 kWh/kW annually
NET METERING
Alectra Utilities offers 1:1 net metering – excess solar earns credits at the full retail rate. With Time–of–Use billing, on–peak credits at 20.3¢/kWh are more than double the off–peak rate. Credits roll over for 12 months. As of May 1, 2026, the simplified micro–embedded generation connection threshold was raised to 12 kW for residential customers (net metering itself remains available for systems up to 500 kW). Ontario's HRSP offers up to $10,000 for solar + battery installations, but solar under HRSP must be sized for load displacement only – net metering is not permitted under HRSP. Customers must choose one or the other.

Ontario’s Time–of–Use electricity rates range from 9.8¢/kWh (off–peak) to 20.3¢/kWh (on–peak), with mid–peak at 15.7¢/kWh (OEB RPP, Nov 2025–Oct 2026). St. Catharines electricity is distributed by Alectra Utilities. Solar panels generate most during daytime on–peak hours, earning you credits at the highest rate. The Ontario Electricity Rebate provides a 23.5% discount on your bill.

Alectra Utilities Time-of-Use rates in St. Catharines

What a kilowatt-hour costs at each tier, and the hours each one applies — OEB Regulated Price Plan, Nov 2025 – Oct 2026. Rates are set province-wide by the Ontario Energy Board, so they are the same whichever utility bills you; only delivery charges differ.

Off-peak
9.8¢/kWh
Evenings, overnight, weekends
$68.60/mo at 700 kWh
Mid-peak
15.7¢/kWh
Shoulder hours, weekdays
$109.90/mo at 700 kWh
On-peak
20.3¢/kWh
The expensive weekday block
$142.10/mo at 700 kWh

Alectra Utilities peak hours, by season

The tiers hold all year; the hours switch twice a year. Weekends and statutory holidays bill at the off-peak rate all day, in both seasons.

SummerMay 1 – Oct 31 · weekdays
On-peak11 a.m. – 5 p.m.
Mid-peak7 – 11 a.m. and 5 – 7 p.m.
Off-peak7 p.m. – 7 a.m.
WinterNov 1 – Apr 30 · weekdays
On-peak7 – 11 a.m. and 5 – 7 p.m.
Mid-peak11 a.m. – 5 p.m.
Off-peak7 p.m. – 7 a.m.

On-peak power costs 2.1× what the same kilowatt-hour costs off-peak. At the Ontario Energy Board's benchmark of 700 kWh a month, that is the difference between $68.60 and $142.10 on the electricity line alone — delivery and regulatory charges are billed separately, and the Ontario Electricity Rebate then takes 23.5% off the total.

This is why solar pays better here than a flat rate would suggest. A rooftop array produces most between 11 a.m. and 5 p.m. — precisely the summer on-peak window — so the power it offsets is the most expensive power St. Catharines buys.

How your system works behind the meter

Most of a St. Catharines system's value comes from power used behind the meter — electricity your panels make and your home uses on the spot, offsetting energy you'd otherwise buy at 9.8¢/kWh. Only the surplus flows past the meter to Alectra Utilities for net-metering credit.

Solar Panels in St. Catharines, Ontario

St. Catharines in the Niagara Region produces 1,150 kWh per kW annually. Alectra Utilities distributes electricity. The Niagara Region’s moderate climate with lake-effect moderation supports strong year-round solar performance.

Ontario’s net metering program credits excess solar at the full retail rate. HRSP ($10K for solar + battery) or net metering available – but not both.

Ontario HRSP - Up to $10,000 for Solar + Battery

Ontario’s Home Renovation Savings Program (HRSP), launched January 2025, offers:

  • Up to $5,000 for solar panels ($1,000/kW)
  • Battery storage at $300/kWh up to $5,000
  • Maximum total program rebate: $12,000 (across all eligible upgrades)

Important – HRSP vs. Net Metering: Solar installed under HRSP must be sized for on-site load displacement only – net metering is not permitted under HRSP. If you prefer net metering (earning 1:1 credits for excess solar), you would not apply through HRSP. Your Xolar advisor can help determine which option provides the best return.

Note: The Canada Greener Homes Grant and Loan programs are now closed.
