VANCOUVER, B.C. — British Columbia’s electric vehicle boom is well under way, but many EV owners might be missing out on an effortless way to slash their annual household utility bills.
Despite the widespread adoption of battery-powered crossovers like the Tesla Model Y across the Lower Mainland, a significant number of drivers have yet to opt into BC Hydro’s optional Time-of-Day pricing plan. By simply utilizing their vehicle's onboard software to change when their vehicle charges, typical drivers could pocket nearly $200 in savings each year without altering their daily commutes.
The Mechanics of Time-of-Day Pricing
BC Hydro's Time-of-Day plan is designed to ease the strain on the provincial electrical grid during peak hours. It financially incentivizes customers to shift heavy energy loads—like charging an EV or running a heat pump—to quieter periods.
Rather than replacing your standard electricity rate, the Time of Day plan acts as a modifier based on the clock:
Overnight Discount (11:00 p.m. to 7:00 a.m.): You receive a 5-cent per kilowatt-hour (kWh) discount.
On-Peak Surcharge (4:00 p.m. to 9:00 p.m.): You pay a 5-cent per kWh premium.
Off-Peak (All other times): Standard electricity rates apply, with no discount or penalty.
For households adjusting standard appliances like a dishwasher, the annual savings can be modest. But for households with an electric vehicle drawing massive amounts of energy every week, that 5-cent overnight discount adds up rapidly.
The Model Y Math: $200 in "Free" Savings
To understand the financial impact, consider a busy Metro Vancouver family driving a Tesla Model Y—currently one of the most popular vehicles on Canadian roads.
Assuming the family drives roughly 2,000 kilometers per month (a mix of daily commuting and weekend errands), the crossover will consume about 330 kWh of electricity every 30 days to maintain its charge.
If this household is on BC Hydro’s standard rate plan, they pay the standard tiered or flat fee for that power. However, if they opt into Time of Day pricing and schedule their vehicle to only accept power between 11:00 p.m. and 7:00 a.m., the math shifts dramatically in their favor:
Applying the 5-cent discount to 330 kWh yields $16.50 of savings per month.
Over the course of a year, that translates to $198 in pure utility savings.
Because a standard Level 2 home EV charger easily replenishes a typical daily commute in just a few hours, the vehicle finishes charging long before the 7:00 a.m. cutoff, ensuring the battery is full and ready for the morning school run.
The Catch: Beware the Peak Surcharge
While the savings are highly predictable, energy experts warn that the Time of Day rate requires a one-time automated setup to ensure it works in your favor.
The program's 5-cent surcharge for electricity consumed during the 4:00 p.m. to 9:00 p.m. on-peak window is designed to discourage grid strain. If a driver returns home from work at 5:30 p.m. and allows their vehicle to charge immediately during the dinner-time rush, the resulting premium will swiftly erase any overnight discounts.
To prevent this, EV owners must utilize their vehicle's built-in touchscreen interface, smartphone app, or a smart home charger to set a strict charging schedule. By programming the car to only initiate charging after 11:00 p.m., the process becomes entirely frictionless. You plug the car in when you get home, but the power won't flow until the discount window opens.
BC Hydro customers can assess their historical energy usage and opt into the Time-of-Day pricing plan directly through their online utility accounts. For an EV driver who already sleeps through the night, making the switch might just be the easiest $200 they earn all year.
