FAQ's

-
Does Avista charge more for electricity at certain times?
Yes. Avista offers time-of-use (TOU) rate plans where electricity costs vary depending on the period. The period—peak, off-peak, mid-peak, or super off-peak—depends on the time, day, and season. This page lists boundaries for 6 active schedules; tou.tools does not publish pricing ($/kWh) details.
-
How do I get Avista time-of-use periods in my app?
Schedules are accessible programmatically via the tou.tools REST API and MCP server for AI agents. By querying a U.S. address or ZIP code, your application can instantly retrieve the current period and next scheduled transition time. Developer API keys are free.
-
Do Avista time-of-use hours change during holidays or seasons?
Yes. Peak hours and rate periods can vary by season (typically summer and winter halves) and special holidays. While some schedules like E-ELEC keep stable hours year-round, others introduce super off-peak windows or adjust peak times. Check each rate plan card above for specific seasonal boundaries.
-
What is the best time to charge an EV under Avista's plans?
For customers on EV-specific plans like 13, 23, the most cost-effective time to charge is during super off-peak or off-peak hours. Charging during these designated windows significantly reduces electricity costs and minimizes demand on the grid.
