Tacoma home energy rebates at a glance
We read Tacoma Public Utilities' pages and the State Department of Commerce page on October 6, 2026. Most Tacoma Power rebates need a Participating Contractor and need your main heat to be electric.
Heat pump
$2,000 for a variable-speed heat pump replacing an electric forced-air furnace. $1,000 for several other swaps. Zero percent loans up to $20,000.
Insulation
$750 each for the attic, walls and crawlspace. Zero percent loans up to $10,000.
Windows and sliding doors
$400 or $200 per sliding door, depending on what you replace.
EV charging credits
Bill credits of $400 each for a Level 2 charger, a smart splitter, electrical work or an outlet. Renters can apply.
Lower-income help
The state gave the City of Tacoma $637,000 and Pierce County $500,000 to run home electrification rebates for households at or below 150 percent of area median income. The state page gives no dollar amount per household, so ask the City. Our Washington home electrification guide explains the program. The federal clean energy credit ended after 2025.
Tacoma homes in numbers
The US Census Bureau's American Community Survey (2020 to 2024) counts 97,298 homes in Tacoma. About 56 percent of households own and 44 percent rent. About 61 percent of homes are detached houses, and 7 percent sit in buildings of two to four units. Tacoma is an older city. About 64 percent of homes were built before 1980 and 27 percent before 1940, while about 18 percent were built in 2000 or later.
For main heating fuel, about 63 percent of homes use electricity, 33 percent use utility gas and about 1 percent use heating oil. Electricity is the leading fuel, which is why Tacoma Power's insulation and window rebates, which require electric heat, can help a majority of homes.
Rebates plus loans
Tacoma Power's zero percent loans are what set it apart. They run seven years and are tied to the same projects as the rebates. A heat pump loan can be up to $20,000 and an insulation loan up to $10,000. You need to own the home and land, have a good payment and credit history with Tacoma Public Utilities and get approval before work starts. For a family that cannot pay a $12,000 heat pump bill at once, the loan can matter more than the rebate. Read the full rules on our Tacoma Power guide.
Renters and electric tanks
With 44 percent of households renting, many Tacoma readers cannot choose the equipment. The EV charging credits are open to renters, and the state's home electrification program covers renters at or below 150 percent of area median income. For everything else, the landlord decides. If your landlord wants to apply, Tacoma Power's page says the home must be served by Tacoma Power and, for insulation and windows, heated mainly with electricity.

Common questions
What rebates does Tacoma Power offer?
On our October 6, 2026 reading: up to $2,000 for a heat pump, up to $2,250 for insulation, $50 to $100 per window, $500 for a water heater and $75 for a smart thermostat, plus EV charging credits and zero percent loans.
Do I need to heat with electricity?
For insulation, windows and the loans, yes. A variable-speed heat pump replacing non-electric heat still earns $1,000.
Do I need a contractor from a list?
Yes for heat pumps, insulation and windows. Tacoma Power requires a Participating Contractor.
Is there a solar rebate?
We did not read one. Washington exempts solar equipment and installation from sales tax through 2029 for systems up to 100 kilowatts.
Is there a federal tax credit?
No. The IRS says it ended for installs after 2025.
