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 the change in usage patterns.
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 a 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 allow 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.
