22 Residential and Farm Large General Service - Primary
Does the hour matter on 22 Residential and Farm Large General Service - Primary? No — one rate, every hour of the year.
- off-peak9.46¢
There is no peak and no off-peak here: the price per kilowatt-hour at 3am is the same as at 6pm, on a Sunday as on a Tuesday, in July as in January, though the price does step up once a month’s use passes the tier threshold shown below. Moving laundry or car charging to another time of day will not change this bill by a cent. What does change it is how much you use, and the fixed charge below, which you pay whether you use anything or not.
What does 22 Residential and Farm Large General Service - Primary cost a year?
| Household | Uses | A month | Per year | Works out to |
|---|---|---|---|---|
| Apartment One or two people, no central air, no electric heat | 4,866 kWh | $938 | $11,260 | 231.4¢ / kWh |
| Family home Three or four people with central air conditioning | 9,453 kWh | $975 | $11,694 | 123.7¢ / kWh |
| Home with an EV Same house, plus an electric car charging overnight | 13,103 kWh | $1,003 | $12,039 | 91.9¢ / kWh |
Estimates, not quotes. We run three made-up but realistic households through this tariff hour by hour for a full year — including the way air conditioning loads the afternoon and an EV loads the small hours. Your own bill depends on when you actually use electricity, which is exactly the thing a per-kWh number hides.
What you actually pay
| Period | Rate | Applies when |
|---|---|---|
| off-peak | 9.46¢ up to 250000 kWh8.55¢ | midnight–midnight |
Plus a fixed charge of $900 per month.
Should you be on 22 Residential and Farm Large General Service - Primary?
This plan bills a demand charge on top of the per-kWh rates: a fee tied to your single highest hour of the month. Two homes using the same total electricity can pay very different amounts if one of them runs the dryer, the oven, and the car charger at the same moment. We do not price demand charges yet, so treat every dollar figure on this page as a floor, not a total.
Before a single kilowatt-hour moves, this plan charges $10,800 a year in fixed fees. On the apartment above that is 96% of the whole bill; on the house with a car charging in it, 90%. Fixed charges are invisible in a cents-per-kWh comparison and they punish small users hardest — if you use very little electricity, the headline rate is the least important number on this page.
Expect the bill to move with the calendar. The same family home costs about $1,004 in July and $956 in February — a $47 spread driven by heating and cooling far more than by anything you chose. Budget against the July figure, not the average, and a summer bill stops being a surprise.
Other Avista plans
Who can be on Avista’s 22 Residential and Farm Large General Service - Primary?
Eligibility is not our judgement — it is written into the tariff Avista filed. This is what that document says:
To Customers in the State of Washington who meet the requirements for service under Schedule 21 and whose electric use qualifies as a "residential load" as defined in the Pacific Northwest Electric Power Planning and Conservation Act, P.L. 96-501, and the Residential Purchase and Sale Agreement contract in effect between the Company and the Bonneville Power Administration. "Residential Load" means all usual residential, apartment, seasonal dwellings and farm electric loads or uses.
Shortened — the clause runs longer in the filing. Quoted from the filed tariff. Your utility decides eligibility, not us; check with them before you switch.
