Key Takeaways
- Monthly bills for average residential customers in Southwest Washington rose by $12.81 on Aug. 1, 2026, with further multi-year adjustments scheduled for 2027 and 2028.
- State regulators at the WUTC removed a costly geothermal proposal and excluded charitable expenses from customer rates to scale back the utility’s original request.

If you rely on natural gas to heat your home or water in Southwest Washington, you have already seen higher base charges on your utility statements. State regulators at the Washington Utilities and Transportation Commission approved a multi-year rate plan for NW Natural Gas that added $12.81 per month to average residential bills effective Aug. 1, 2026. While the utility originally requested a steeper price hike, regulators stepped in to scale back overall revenue requirements and strip out non-essential project costs. Alongside this base rate increase, your 2026 billing statements reflect a slight Nov. 1 supply rate reduction and updated state climate fees. In this guide, we break down what the NW Natural rate increase in Washington for 2026 means for your household or small business budget, which communities are affected, and the practical steps you can take today to lower your monthly gas bill.
Breakdown of the NW Natural Rate Increase Schedule (2026–2028)
Under the three-year multi-year rate plan approved in WUTC Docket UG-250610, NW Natural Gas is authorized to collect $20.1 million in additional revenue during the first year starting Aug. 1, 2026. Additional revenue adjustments of $7.5 million and $7.4 million will take effect in August 2027 and August 2028, respectively. How this NW Natural Washington rate case impacts your specific monthly statement depends on your customer classification and when your property was first connected to the gas distribution grid.
Year-by-Year Residential Monthly Bill Impact
For a typical residential household connected on or before July 25, 2021, the rate plan phases in bill adjustments over three annual steps. These established connections see an approximate 20% rate increase in Year 1, followed by roughly 5% increases in Years 2 and 3, while newer residential connections installed after that July 2021 cutoff experience slightly different percentage adjustments due to separate line extension cost recovery tariffs.
| Effective Date | Estimated Percentage Increase | Average Monthly Bill Increase | Cumulative Monthly Increase |
| Aug. 1, 2026 | ~20% | +$12.81 | +$12.81 |
| Aug. 1, 2027 | ~5% | +$4.94 | +$17.75 |
| Aug. 1, 2028 | ~5% | +$5.24 | +$22.99 |
By the time the third adjustment takes effect in August 2028, the average residential customer will see their monthly bill increase by a total of $22.99 compared to pre-August 2026 rates.
Small-Commercial and Industrial Rate Increases
Local small business owners and commercial property managers in Southwest Washington also face higher operating costs under the approved rate schedule. Existing small-commercial customers connected on or before July 25, 2021 face an average bill increase of approximately 21% in Year 1 (August 2026 through July 2027) and roughly 6% in each of the following two years, based on an average usage of 54.6 therms per month.
Newer small-commercial accounts see an approximate 17% increase in Year 1 followed by roughly 5% adjustments in Years 2 and 3. Meanwhile, large industrial firm customers using an average of 11,973 therms per month experience an approximate 12% bill increase during the first year of the rate plan.
Fixed Base Monthly Customer Charge Adjustments
Beyond the per-therm delivery rates you pay for the gas you burn, the settlement under WUTC Docket UG-250610 also increases the NW Natural fixed base charge. The Fixed Base Monthly Customer Charge is the mandatory monthly fee every account holder pays simply to remain connected to the natural gas grid, regardless of how many therms you consume during a billing cycle. Familiarizing yourself with natural gas measurements can help you track how these volumetric therms and fixed fees add up each month.
Because this base fee covers fixed infrastructure expenses like meter maintenance, customer service, and billing systems, turning off your furnace or reducing your gas usage will not lower this portion of your bill. Low-usage households and seasonal gas customers who only use gas for a stove or fireplace still have to pay this higher fixed monthly charge year-round.
Additional 2026 Rate Adjustments: November PGA and Climate Act Fees
Your total monthly gas bill is made up of more than just base infrastructure rates. Understanding your natural gas bill to get a complete picture of Southwest Washington natural gas prices in 2026 means you also need to account for annual wholesale gas supply adjustments and state-mandated carbon compliance fees. Reviewing how these seasonal pass-through adjustments and state climate programs work will help you anticipate changes to your monthly statements throughout the year.
November 1, 2026 Purchased Gas Adjustment (PGA) Rate Decrease
Every autumn, utilities adjust their supply rates through the NW Natural Purchased Gas Adjustment 2026 filing to reflect changes in the wholesale cost of natural gas. Effective Nov. 1, 2026 through Oct. 31, 2027, Washington customers actually receive a slight rate reduction on the supply portion of their bills because wholesale market prices dropped over the past year.
For a typical residential customer using 55 therms per month, this autumn adjustment provides a combined monthly reduction of approximately $1.17. That savings includes $0.32 from the direct PGA wholesale gas pass-through and $0.85 from energy-efficiency program true-ups. Small-commercial customers save about $3.00 per month under the same filing. Keep in mind that NW Natural does not mark up wholesale gas supply costs — you pay the exact market price the utility pays to secure the fuel.
📌 Quick Fact: While the Nov. 1, 2026 PGA decrease saves the average household about $1.17 per month, it only partially offsets the $12.81 base rate hike that took effect in August.
Climate Commitment Act (CCA) Fee and Credit Updates
Your billing statement also includes separate line items tied to Washington Climate Commitment Act gas rates, which were updated on June 1, 2026 under the state’s Cap-and-Invest program. To help Washington meet its greenhouse gas reduction targets, natural gas utilities must purchase carbon allowances at state auctions to cover the emissions associated with their customers’ fuel use.
When you review your monthly statement, you will see two specific entries related to this law: the Climate Act Fee and the Climate Act Credit. The Climate Act Fee recovers the utility’s compliance costs to purchase required greenhouse gas allowances, while the Climate Act Credit returns revenue generated from those allowance auctions back to eligible customers to help soften the financial impact on households.
Why Rates Changed and What Regulators Trimmed (Docket UG-250610)
Utilities periodically file general rate cases to cover necessary system maintenance, safety upgrades, and rising infrastructure costs across their pipeline network. In its initial filing for WUTC Docket UG-250610, NW Natural originally requested $36.5 million in total new revenue over the multi-year period. However, the final approved rate plan reflects a negotiated settlement among NW Natural, commission staff, and consumer advocacy groups that trimmed the utility’s initial pricing demands.
Key Cost Exclusions by State Regulators
To protect ratepayers from excessive costs, state regulators attached two key conditions to the final rate order:
- Removal of Vancouver Geothermal Project: The commission removed a proposed geothermal heating and cooling pilot project in Vancouver from customer rate recovery after the project experienced a significant reduction in expected grant funding.
- Exclusion of Charitable Expenses: Regulators barred the utility from recovering any remaining corporate charitable contributions through customer billing rates.
During the proceedings, the Washington Attorney General’s Public Counsel Unit also opposed keeping generous line extension allowances that subsidize new gas connections. While the WUTC ultimately left the line extension tariff unchanged in this docket, removing the geothermal project and charitable costs helped reduce the immediate bill impact compared to the company’s original proposal.
New Consumer Credit and Debt Collection Protections
Alongside trimming revenue requests, the WUTC included vital legal protections in the final rate order to support struggling ratepayers and protect household financial health:
- Credit Reporting Ban: Collection agencies working on behalf of NW Natural are strictly prohibited from reporting late gas bill payments to credit bureaus, ensuring a past-due winter heating bill will not damage your credit score.
- Mandatory Energy Burden Reviews: NW Natural must formally review household energy burden — the percentage of household income spent on energy bills — every two to four years to ensure its low-income discount programs remain sufficient as rates rise.
Southwest Washington Communities Affected by the Rate Hike
NW Natural Gas serves approximately two million people across Oregon and Southwest Washington. While neighboring customers recently navigated a Cascade Natural Gas rate settlement in Oregon, the rate decision issued by the Washington commission specifically impacts residential, commercial, and industrial customers located within the company’s Washington service territory.
Covered Cities and Counties
Whether you are monitoring Clark County natural gas rates or managing a property further east along the Columbia River Gorge, the new rate structure applies to accounts in the following municipalities and surrounding unincorporated areas:
- Clark County: Vancouver, Camas, and Washougal.
- Skamania County: Carson and North Bonneville.
- Klickitat County: White Salmon, Bingen, Klickitat, and Dallesport.
Actionable Ways to Lower Your Gas Bill in Washington
Higher utility rates can put a strain on your monthly budget, but you do not have to absorb the full cost increases unprepared. If you are looking for practical ways to save on your gas bill, taking advantage of state-mandated relief programs, payment smoothing tools, and eco-conscious energy efficiency upgrades can help keep your heating expenses manageable.
Enroll in the Washington Bill Discount Program
Income-qualified households can receive significant ongoing relief through the NW Natural Bill Discount Program. Depending on your household size and gross annual income (for households earning at or below 80% of the Area Median Income), you can receive a monthly discount of 15% to 80% on your gas bill. Applying is quick and straightforward, and applicants can self-certify their income without needing to upload tax returns or pay stubs.
💸 Money-Saver: Even if you never qualified for utility assistance in the past, check the current income thresholds on NW Natural’s website — a family of four in Clark County can earn up to 80% of the local median income and still lock in at least a 15% monthly rate discount.
Utilize Energy Assistance and Weatherization Grants
If you need emergency help or want to permanently reduce your energy consumption through an energy-saving option, several grant-funded programs are available:
- LIHEAP and GREAT Grants: Federal funding through the Low-Income Home Energy Assistance Program and NW Natural’s Gas Residential Energy Assistance Tariff provide direct grant funds to help pay past-due or current heating bills. You can explore available state funds via the WUTC Energy Assistance Directory.
- Free Home Weatherization: Income-eligible renters and homeowners can receive free energy efficiency upgrades — such as attic insulation, air sealing, and ENERGY STAR furnace retrofits — through local community action agencies in Clark, Skamania, and Klickitat counties.
Switch to Equal Pay Budget Billing
To avoid high bill spikes during the cold winter heating season, consider enrolling in Equal Pay budget billing. This option averages your projected annual natural gas usage into 12 equal monthly installments, making your household budget far more predictable throughout the year.
Preparing Your Household Budget for Winter Heating Costs
While the multi-year rate increases approved by state regulators mean higher baseline costs through 2028, taking an active approach to your home energy use can significantly cushion the financial blow. The slight Nov. 1, 2026 PGA rate decrease offers a modest bit of breathing room, but the biggest savings come from pairing that supply relief with home weatherization and income-qualified bill discounts before peak winter usage hits. By sealing drafts, dialing back your thermostat a few degrees, learning how to read your gas meter to monitor consumption, and enrolling in assistance or Equal Pay plans early, you can keep your home comfortable all winter without letting your natural gas bill derail your budget.
