About TOU Pricing

With TOU prices, the price depends on when you use electricity. You can help manage your electricity costs by shifting your usage to lower price periods when possible.

There are three TOU periods:

  • Off-peak: When demand for electricity is lowest. 

  • Mid-peak: When demand for electricity is moderate. 

  • On-peak: When demand for electricity is generally higher. 

People use electricity differently depending on the season, so the TOU price periods are different in the winter than they are in the summer.

About Tiered Pricing

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. 

For small business customers, the Tier threshold 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.

A small number of customers use tiered rates. Tiered Pricing is broken down into set amounts of electricity that may be used at a specific rate; once this set amount is exceeded, the rate changes to a more expensive tier. As of November 1, 2021, Tiered prices for non-residential customers are:

First Tier - Up to 750 kWh


Second Tier - More than 750 kWh

9.8 cents per kWh

11.5 cents per kWh
