Compare two electricity plans for the same usage by entering each plan's average price per kWh, or start from an illustrative preset.
This tool compares two plans for the same amount of electricity. Each plan is reduced to one average price per kWh for your usage pattern, then multiplied by your kWh. Charges that do not change between plans (delivery, regulatory charges, the basic charge when it is the same) can be added once to both.
How the presets were built (illustrative usage splits): Ontario prices effective 1 November 2026: TOU off-peak 9.1¢, mid-peak 14.6¢, on-peak 18.9¢; ULO overnight 3.7¢, weekend off-peak 9.1¢, mid-peak 14.6¢, on-peak 37.7¢; tiered 11.2¢ up to the winter threshold of 1,000 kWh a month. TOU average for a 65/17/18 split = 0.65 × 9.1 + 0.17 × 14.6 + 0.18 × 18.9 = 11.8¢. ULO with 55% overnight, 12% weekend off-peak, 25% mid-peak and 8% on-peak = 9.79¢. ULO with only 20% overnight, 20% weekend off-peak, 40% mid-peak and 20% on-peak = 15.94¢. BC Hydro: at 2,400 kWh in a 61-day period the Tier 1 threshold is 61 × 22.1918 = 1,353.7 kWh, so the average is (1,353.7 × 11.87¢ + 1,046.3 × 14.08¢) ÷ 2,400 = 12.83¢ against the flat 12.70¢ (the two basic charges differ slightly; add them yourself).
Worked example: 700 kWh, first preset: TOU 700 × $0.118 = $82.60; tiered 700 × $0.112 = $78.40. Tiered is about $4 cheaper for this profile. Change the split and the answer can reverse.
Limits: find your own split in your utility's online usage data. Ontario's winter tier threshold applies 1 November to 30 April; above it, part of your usage is charged at 13.2¢. See TOU vs ultra-low overnight vs tiered.
