Rate Flex D
Rate Flex D: Potential for substantial savings
Rate Flex D is a dynamic rate that can save you quite a bit of money. Electricity is cheaper than the base rate in winter, except during peak demand events, when it’s more expensive.
How Rate Flex D works
Rate Flex D is different than the base rate (Rate D). This is how it works.
-
In winter,
- outside peak demand events, the price of electricity is below the base rate, so you can save money.
- during peak demand events, electricity is billed at a high price (53.526¢/kWh). You’ll have to shift nonessential electricity use or limit it to reduce costs. The day before a peak demand event, you’ll receive a notification by email and, if you like, through our mobile app.
- The rest of the year, Rate D (base rate) prices apply.
Risk
The risk depends on your energy use habits. Your bill could be higher at Rate Flex D than at the base rate if you don’t take the necessary steps during peak demand events when the price is higher. It’s important to use as little electricity as possible during those events, so you aren’t penalized.
Peak demand events
Peak demand events can take place Monday to Friday from December 1 to March 31, from 6 to 9 a.m. and from 4 to 8 p.m. There may be 25 to 33 events per winter, at most, for a maximum of 100 hours in all.
A customized tool to track your results

- Your energy use during peak demand events and outside events
- Upcoming events for which you have received a notification
