The U.S. Energy Information Administration published its Short-Term Energy Outlook and its Winter Fuels Outlook on Monday, October 6, 2026. For the four in ten American homes that heat with electricity, the forecast is a winter bill of $1,196 on average, up 4% from last winter. Residential electricity is expected to average 18.21 cents per kWh in 2026, up from 17.30 cents in 2025, and 18.68 cents in 2027.
If you own a portable power station or a home battery, or you are thinking about one because of these numbers, here is the honest answer: a battery protects you from outages, not from the bill. On a flat rate it saves nothing. On a time-of-use plan it saves a little, and the math below shows how little. BackupPowerHub does not run lab tests (see our editorial guidelines); every figure here comes from the EIA report or from arithmetic you can check.
- Electric heat: $1,196 this winter, up 4%. The West is up 9%.
- Natural gas: $640, down 9%. Propane: $1,246, down 3%. Heating oil: $2,115, up 21%.
- Flat-rate plan: a battery changes your bill by $0.
- Time-of-use plan: a 2 kWh battery shifts about $60 to $120 a year. A $900 unit pays back in 7 to 15 years, longer than its battery will last.
- What a battery actually buys: a fridge, a router and a CPAP running through an outage.
What the EIA forecast says, in plain numbers
The report covers October 2026 through March 2027. The EIA assumes a winter about as cold as last year and as the 10-year average, so these are price effects, not weather effects.
| Main heating fuel | Share of U.S. homes | Forecast winter spend | Change vs last winter |
|---|---|---|---|
| Electricity | More than 40% | $1,196 | +4% (price +3%, use slightly up; West +9%) |
| Natural gas | 46% | $640 | -9% (West +7% on colder weather) |
| Propane | Small, mostly Midwest and Northeast | $1,246 | -3% (Northeast -15%) |
| Heating oil | About 3%, mostly Northeast | $2,115 | +21% |
Behind the retail number, wholesale power averages $52 per megawatt-hour in 2026, 11% more than in 2025, which the EIA blames on winter storm Fern and a hot July. The PJM region (New Jersey, Pennsylvania, Maryland, Virginia, Ohio, Delaware, the District of Columbia and parts of neighboring states) is the outlier: wholesale prices up 41% this year, with a 7% decline expected in 2027. Wholesale is only one slice of a home bill, next to transmission, distribution and capacity charges, so a 41% wholesale jump does not mean a 41% bill.
The battery-and-bill math, on a real plan
A battery lowers a bill in exactly one case: a time-of-use plan, where you charge at the cheap hours and run the house from the battery during the expensive ones. Here is what that is worth with a 2 kWh portable unit, the most common size people buy for home backup.
What you can shift
A 2,048 Wh unit delivers about 1,740 Wh after inverter losses (2,048 x 0.85). That is one evening of fridge, lights, TV and router, every day.
What it saves
On a plan with a 15-cent gap between peak and off-peak, about 17 cents a day once you pay for the charging losses. With a 25-cent gap, about 33 cents. That is $60 to $120 a year.
Payback
At $900 for the unit, 7 to 15 years. LiFePO4 cells are rated for about 3,000 to 4,000 full cycles, which is 8 to 11 years of daily cycling. The battery wears out before it pays off.
The arithmetic: you buy about 2.25 kWh off-peak to put 1.74 kWh back into the house, because charging and discharging each lose a little. With peak at 33 cents and off-peak at 18 cents, you avoid 1.74 x $0.33 = $0.57 and you pay 2.25 x $0.18 = $0.41. Net: 16 to 17 cents a day. Scale the unit up and the ratio stays the same: a 4 kWh home battery saves twice as much and costs about twice as much.
Two things make the picture worse, not better. Most U.S. homes are still on a flat rate, where the battery saves exactly nothing. And on the national average of 18.21 cents, the whole 1.74 kWh you shift is worth 32 cents of electricity: there is simply not much money in a day’s worth of fridge power.
What actually moves an electric heating bill
The EIA number is driven by two things, price and consumption, and you only control the second one. The usual levers are the heating setpoint (each degree lower for the whole winter is a few percent of heating energy), the water heater temperature, and air leaks around doors, windows and attic hatches. A heat pump replacing resistance heat is the big one, but it is a renovation, not a gadget.
A power station belongs in a different budget line: insurance. The same 2 kWh unit that is worth 17 cents a day on a time-of-use plan runs a full-size refrigerator for about 15 hours, a router for three and a half days, or a CPAP with its humidifier for about four nights when the grid is down. That is the purchase decision, and it has nothing to do with the 18.21 cents.
Who should still look at a battery this winter
- Electric-heat homes in outage-prone areas. When the power fails, an all-electric house loses heat, hot water and cooking at once. A battery cannot run a central heat pump, but it keeps a space heater on low, the fridge, the phones and the medical devices going. Start with our home backup guide.
- Households on a time-of-use plan with a wide gap. If your peak-to-off-peak spread is 25 cents or more and you already want backup, the savings are a bonus on top of the insurance, not a reason on their own.
- Heating-oil homes in the Northeast. Your problem is the 21% oil increase, not electricity. A battery does not touch that bill either, but it keeps the oil burner’s controls and pump running in a blackout, which oil heat needs.
Everyone else: keep the money, or put it toward the thermostat and the air sealing.

Before buying any of them for bill reasons, open your utility’s rate page and write down your peak and off-peak prices. Multiply the gap by 1.7 kWh for a 2 kWh unit, or by 3.3 kWh for a 4 kWh one. That is your daily saving, before losses. If the number makes you shrug, you have your answer.

Quick answers
Does a home battery lower your electric bill?
Only on a time-of-use plan, and only a little. A 2 kWh unit shifting one evening of use saves about $60 to $120 a year on a plan with a 15 to 25 cent gap between peak and off-peak prices. On a flat rate it saves nothing.
How much will electricity cost in 2026 and 2027?
The EIA’s October 2026 outlook puts the U.S. residential average at 18.21 cents per kWh in 2026 and 18.68 cents in 2027, up from 17.30 cents in 2025. Homes that heat with electricity are forecast to spend $1,196 this winter, 4% more than last winter.
Why are electric bills going up when gas bills are going down?
Natural gas prices fell, so gas-heated homes spend 9% less this winter. Electricity prices are driven by wholesale power (up 11% in 2026 after winter storm Fern and a hot July, and up 41% in the PJM region) plus grid costs that keep rising regardless of fuel prices.
