“Do I get PSE rebates or Tacoma Power rebates?” is one of the most common questions we get from homeowners in Pierce County. The answer depends entirely on which utility bills you for electricity, and that is not always what you would guess from your street address.
The Short Answer
Look at your electric bill. Whichever utility is on it is the one whose rebate program you qualify for. That is the only thing that matters for eligibility.
Why Address Is Not a Reliable Guide
Tacoma Public Utilities (TPU) serves most of the city of Tacoma. Puget Sound Energy (PSE) serves most of the rest of Pierce County. But the boundary is not clean:
- Parts of unincorporated Tacoma area and edges of the city can be PSE
- Some annexed areas kept their original PSE service
- Fircrest, University Place, Lakewood, and the peninsula are mostly PSE
- DuPont, Puyallup, Gig Harbor, Federal Way, and areas east and south are mostly PSE
- Ruston is TPU
If you rely on where you think the boundary is, you can waste weeks applying for the wrong rebate.
How to Confirm Your Utility in 30 Seconds
- Open your most recent electric bill.
- Look at the letterhead or logo.
- If it says Puget Sound Energy or PSE, that is your utility.
- If it says Tacoma Public Utilities, Tacoma Power, or MyTPU, that is your utility.

How Their Rebate Programs Differ
| Feature | PSE | Tacoma Power (TPU) |
|---|---|---|
| Service area | Most of Pierce County outside Tacoma | City of Tacoma, most areas |
| Heat pump rebates | Multiple tiers based on efficiency | Similar tier structure; different amounts |
| Heat pump water heater | Yes, sizable rebate | Yes, sizable rebate |
| Weatherization (insulation, air sealing) | Yes, robust program | Yes, robust program |
| Income qualified assistance | HELP program and partner agencies | Multiple programs, higher payouts |
| Application processing time | 6 to 10 weeks typically | 6 to 10 weeks typically |
What About Gas?
PSE is the gas utility for most of Pierce County, including the city of Tacoma. That means:
- In Tacoma with TPU electric, PSE bills your gas
- Outside Tacoma with PSE electric, PSE bills both electric and gas
Some homes have both PSE and TPU accounts (TPU electric plus PSE gas). This is common in Tacoma and important when planning a fuel switch from gas to electric heat pump. You can potentially qualify for PSE fuel switching incentives (if offered) plus TPU heat pump rebates.

Frequently Asked Questions
Can I get both PSE and TPU rebates on the same project?
No. You are one utility’s customer at that address. Utility rebates are not stackable across utilities on the same equipment.
What if I have TPU electric but I am replacing a PSE gas furnace with a heat pump?
Your rebate goes through TPU because they serve your electric. If PSE offers a fuel switching or gas decommissioning incentive that year, ask about it separately.
What if I recently moved and am not sure yet?
Call the number on the electric bill you last received or check the property’s utility account online. Or call the seller or your realtor.
Can federal 25C credits or IRA rebates stack with utility rebates?
In many cases, yes. Federal incentives are separate from utility rebates and have their own income and equipment rules. We recommend confirming stacking eligibility with a tax professional and checking current IRS and state guidance.
Does GreenFlow handle both PSE and TPU rebate paperwork?
Yes. We are enrolled in both programs and prepare and submit rebate applications on our customers’ behalf. Whether you are PSE or TPU, we handle the paperwork.
