Puget Sound Energy Inc rate plans
3 residential plans are currently open to new customers that we can price side by side. Some charge different prices depending on the hour — which is where most of the savings hide.
What does Puget Sound Energy cost at a normal month’s usage?
A household using 1,000 kWh a month pays about $2,380 a year on the cheapest of the 8 plans we can price here — 8 (Residential & Farm General Service - Single Phase) — and $2,965 on the priciest. Same house, same wires.
| A month of | Cheapest, a year | On which plan | Priciest |
|---|---|---|---|
| 500 kWh | $1,251 | 8 (Residential & Farm General Service - Single Phase) | $1,590 |
| 1,000 kWh | $2,380 | 8 (Residential & Farm General Service - Single Phase) | $2,965 |
| 2,000 kWh | $4,637 | 8 (Residential & Farm General Service - Single Phase) | $5,714 |
The same plan is cheapest at every level of use here, so the answer does not turn on how much you use. Estimates from the filed tariff, priced hour by hour on a household with central air — not a quote.
How much does the plan you pick actually matter here?
Run the same three-bedroom house with central air through every plan Puget Sound Energy Inc files, and the bill lands anywhere between $1,957 and $2,196 a year. That $239 spread is not a difference in electricity — it is the same kilowatt-hours, from the same wires, priced under different rules. Nobody sends you a letter when you are on the wrong side of it.
2 of these 3 plans price by the hour. Those are the ones where moving laundry, dishes, or car charging into the cheap window changes the bill; on the rest, the clock is irrelevant and only the total matters. Which camp you belong in is the first question worth settling, because it decides whether shifting your day is worth anything at all.
How Puget Sound Energy compares across Washington
Run the same three-bedroom house with central air through its default plan at each of the 6 Washington utilities we cover, and Puget Sound Energy is the dearest of the lot at about $1,957 a year; the state median is $1,180. The cheapest, PUD No 1 of Cowlitz County, charges $1,020 for identical use — a gap set by the address, not by anything either household did.
The other two households tell the same story in different sizes: a small apartment pays about $1,028 here against a state median of $791, and the same house with an electric car charging overnight about $2,732 against $1,508. Effective rate, fixed charge included, is 20.7¢ per kilowatt-hour for the family home.
Inside Puget Sound Energy itself, the gap between its cheapest and dearest plan for that house is $239 a year — less than the $937 between Washington's cheapest and dearest utilities. Here the address decides most of the bill; the plan decides the rest.

When are Puget Sound Energy’s peak hours?
Puget Sound Energy’s peak hours are 7am–10am, 5pm–8pm, October–March on all 4 of its time-of-use plans. Everything outside those hours is off-peak, apart from a mid-priced shoulder period. Weekends are off-peak all day.
At peak, 307 charges 58.4¢ a kWh; off-peak it is 15.9¢ — 3.7× apart. These hours only matter on a time-of-use plan — the default plan, 7 (Residential Service - Three Phase), charges one rate at every hour.
| Plan | Peak hours | Peak | Off-peak | Weekends |
|---|---|---|---|---|
| 307 (Residential Time of Use Pilot) - Single Phase | 7am–10am, 5pm–8pm, October–March | 58.4¢ | 15.9¢ | off-peak all day |
| 307 (Residential Time of Use Pilot) - Three Phase | 7am–10am, 5pm–8pm, October–March | 58.4¢ | 15.9¢ | off-peak all day |
| 327 (Residential Time of Use 3-tier Pilot) - Single Phase | 7am–10am, 5pm–8pm, October–March | 55.5¢ | 12.7¢ | off-peak all day |
| 327 (Residential Time of Use 3-tier Pilot) - Three Phase | 7am–10am, 5pm–8pm, October–March | 55.5¢ | 12.7¢ | partly priced |
On 327, every kilowatt-hour a day you move from 7am to midnight is worth about $156 a year in the month the gap is widest — an electric car or a water heater on a timer is the kind of load that actually moves. When to charge an electric car →
Which plan would cost you least?
No bill upload, no sign-up. Tell us roughly what a month costs you and what runs on electricity — we price every plan against the same household and show you the gap.
That adds up to 7,549 kWh a year. Compare it to the total on your bill and adjust until it’s close.
Same usage, different plan
$6,614a year
That is the gap between the cheapest plan you could be on — 8 (Residential & Farm General Service - Single Phase) — and the priciest. Not by using less power. By being billed differently for the same power.

An estimate, not a quote. Supply charges move month to month, and your real usage pattern is not exactly this one. What it does show reliably is the gap between plans — both are priced off the same assumptions.
Before you switch anything
- What is a time-of-use electricity rate?
The same kilowatt-hour, priced differently depending on when you use it.
- Should you switch to a time-of-use electricity plan?
A wide peak-to-off-peak gap is a lever, not a saving. Levers need something to move.
