Cost to run a pool pump in Maine
At Maine’s average residential rate of 28.63¢ per kWh, a pool pump drawing 1500W for 8 hours a day costs about $105 a month. Change the numbers below to match how you actually use yours.
The cooling season in Maine is short. A pool pump will earn its running cost over a few weeks rather than a few months, which makes the per-day figure a more useful number here than the annual one.

Why the cost differs in Maine
Maine has the 46th cheapest residential electricity of the 51 US states and territories we track, at 28.63¢ per kWh against a national average of 18.44¢. That is +55.3% compared with the national figure. Maine combines high winter heating demand with constrained regional transmission, a costly pairing. Retail supplier choice is available, so contracted rates vary. Heat pump adoption here is among the highest in the country, which is shifting the winter load profile: households that once burned oil now draw electricity through the coldest months, when New England generation costs peak.
For this appliance specifically, the difference works out to an extra $446 a year over what the same pool pump would cost at the national average rate. Run the identical appliance in Hawaii and it would cost $2,278 a year; in Idaho it would cost $541. That spread of $1,737 is entirely down to location.
At Maine's rate this single pool pump accounts for roughly 42% of a typical household's entire annual electricity bill. It is not a rounding error on your statement - it is one of the largest single line items in it.
Because Maine is among the most expensive states for electricity, efficiency upgrades pay back faster here than almost anywhere. A more efficient pool pump that saves a given number of kilowatt-hours saves noticeably more money in Maine than the same upgrade would in a cheap-power state.
Because Maine has retail supplier choice, the state average blends many different contracted rates. If you have shopped for a plan, your own price per kWh is the number to put in the calculator.

About running a pool pump
Single-speed pool pumps are among the largest discretionary loads in a home. Variable-speed models running longer at lower speed use dramatically less energy for the same filtration.
What actually changes the cost
- At typical use this is a major load - around 4,380 kWh a year. Efficiency upgrades here pay back faster than on any small appliance.
- Models vary widely, from about 750W to 2500W. Check the nameplate on your own unit rather than assuming an average, because the spread is more than 2x.
- If your utility offers time-of-use pricing, shifting this load off-peak can cut its cost substantially without using any less energy.
How we worked this out
The arithmetic is simple and we would rather show it than hide it. Divide watts by 1,000 to get kilowatts, multiply by hours of use and by the duty cycle to get kilowatt-hours, then multiply by your rate:
1500W ÷ 1000 × 8h = 12.000 kWh/day × 28.63¢ = $3.436 per day
One honest caveat: Maine’s figure is a state average published by the EIA. Your own utility’s tariff, any time-of-use pricing, fixed monthly service charges and local taxes all shift the real number. Put your actual per-kWh rate into the calculator above for a figure that reflects your bill.
Questions about pool pump running costs
How many watts does a pool pump use?
A typical pool pump draws about 1500 watts while running, with most models falling between 750W and 2500W. Check the nameplate label or manual for your specific unit - the range is wide enough that averages can mislead.
How much electricity does a pool pump use per day?
At around 8 hours of use a day and a 100% duty cycle, that works out to roughly 12 kWh per day, or about 360 kWh a month. Your actual figure depends on your usage and model.
Why does the cost differ so much between states?
Residential electricity rates across the US range from about 12.35 cents per kWh in North Dakota to 46.62 cents in Hawaii - nearly a fourfold difference. The same pool pump, used identically, therefore costs almost four times as much to run in the most expensive state as in the cheapest.
Is it cheaper to run a pool pump at night?
Only if you are on a time-of-use or variable tariff. On a flat rate, the time of day makes no difference to cost. If you are on time-of-use pricing, off-peak hours are typically materially cheaper, and shifting this load can reduce its cost without reducing usage.
