Ultra-Low Overnight Pricing

About Ultra-Low Overnight Pricing

With the Ultra-Low Overnight (ULO) price plan, there are four price periods: On-peak, Mid-peak, Weekend Off-peak, and Ultra-Low Overnight. 

The ultra-low overnight period is between 11:00 p.m. to 7:00 a.m. every day, when demand for electricity is lowest on average, and there is a higher on-peak price for consumption between 4:00 p.m. to 9:00 p.m. on weekdays, when demand is usually higher.

The ULO price periods are the same all year round. With ULO pricing, you can help manage your electricity costs by shifting high usage activities, like electric vehicle charging, to lower price periods when possible.

ULO rates are set by the Ontario Energy Board.

  • For Time-of-Use Pricing, Tiered Pricing, and Ultra-Low Overnight Pricing, Alectra Utilities passes this cost through to you, without mark-up, and pays it directly to our suppliers.
  • Customers who have signed a contract with an energy retailer pay the price stated in their contract plus the Global Adjustment.
