Electricity Rates

There are four ULO price periods:

• Ultra-Low Overnight, when demand for electricity is lowest on average.
• Weekend Off-peak, when demand for electricity is generally lower.
• Mid-peak, when demand for electricity is moderate.
• On-peak, when demand for electricity is highest on average.

The ULO price periods are the same in the summer as they are in the winter. On weekends and holidays the cheapest rates are in effect all day. View the Holiday Schedule for Time-of-Use and Ultra-Low Overnight.

With Tiered prices, you can use a certain amount of electricity each month at a lower price. Once that limit (called a threshold) is exceeded, a higher price applies. The threshold changes with the season to reflect changing usage patterns – for example, there are fewer hours of daylight in the winter and some customers use electric heating.

In the winter period (November 1 – April 30), the Tier threshold for residential customers is 1,000 kWh, so that during the heating season households can use more power at the lower price.

In the summer period (May 1 – October 31), the Tier threshold for residential customers is 600 kWh. The Tier threshold for small business customers is 750 kWh all year round.

Tiered prices give you the flexibility to use electricity at any time of day at the same price, although that price will change if you exceed the threshold during the month.
