Washington residents who pay Puget Sound Energy bills are about to get a formal chance to weigh in on proposed rate increases that could significantly raise monthly costs starting in early 2027. The state Utilities and Transportation Commission is holding two public comment hearings in the coming weeks as it considers PSE's request to raise residential electric rates by 16.75 percent and natural gas rates by roughly 13 percent.
If the UTC approves the request, the average monthly bill for a residential electric customer would rise by about $28 starting in early 2027. The average natural gas customer would see their monthly bill increase by approximately $14. Additional, smaller rate increases are proposed for 2028 and 2029 as part of the same three-year plan.
Why PSE Says It Needs the Increase
Puget Sound Energy is requesting more than $3 billion in total system investment over the next three years, pointing to increased strain on its electric grid as the primary driver. The utility serves a large portion of western Washington, including Whatcom County, and has cited growing electricity demand tied to data centers, electric vehicle adoption, and the broader electrification of heating and transportation as factors pushing system capacity toward its limits in ways that were not anticipated when the current rate structure was designed.
Data centers alone represent a substantial new category of industrial electricity consumption in western Washington, and several large facilities have come online or been announced in recent years. Each of those facilities requires a dedicated interconnection to the grid, often including substation upgrades and new transmission lines that PSE says must be paid for through the capital investment program now being proposed. At the same time, the rapid growth of residential electric vehicle ownership has shifted electricity consumption patterns, creating new peak demand periods and requiring investment in distribution infrastructure that was sized for a different era of household energy use.
Among the specific projects linked to this demand increase is a large lithium-ion battery storage facility proposed for the Custer area in northern Whatcom County, along with several other renewable energy projects targeted for Whatcom and Skagit counties. These facilities are designed to help PSE manage peak demand and integrate renewable generation, but they also represent significant capital expenditures that the utility says must be recovered through rates. Battery storage is an increasingly important tool for utilities managing grids with high proportions of variable renewable energy, because it allows power generated during low-demand periods to be stored and dispatched when demand spikes.
PSE's request is not without opposition. Washington State Attorney General Nick Brown challenged the company's proposal in July, arguing that the scale of the increase places an unreasonable burden on ratepayers. The Attorney General's office often participates in rate cases as an advocate for consumers, and its involvement signals that the legal and policy arguments around this rate request will receive serious scrutiny. The UTC hearing process is designed in part to create a formal record of public concern that commissioners must weigh alongside the utility's financial justifications. Past rate cases in Washington have resulted in commissioners approving amounts smaller than what the utility requested, rejecting specific cost categories as imprudent, or restructuring how costs are allocated across customer classes.
How to Participate in the Hearings
The Washington Utilities and Transportation Commission is holding an in-person public hearing in Lacey on Tuesday, September 29. A virtual public hearing will follow on Wednesday, October 7. Both hearings give members of the public an opportunity to speak directly on the record about how the proposed rate increases would affect them.
For Whatcom County residents who cannot travel to Lacey for the in-person session, the October 7 virtual hearing provides an accessible alternative. Participating in a virtual hearing requires only an internet connection and, in most cases, a computer or smartphone with a camera and microphone. Details on how to join the virtual session, including any registration requirements, are available through the UTC's website.
Residents can also submit comments through several other channels without attending a hearing in person. Written comments can be sent by email to comments@utc.wa.gov, by phone at 888-333-9882, or by physical mail to the UTC at P.O. Box 47250, Olympia, WA 98504-7250. An online comment form is available on the UTC's website as well. All of these comment submissions become part of the official proceeding record, meaning commissioners are required to consider them as part of their deliberations. Providing specific, personal details about how a $28 monthly increase would affect your household budget is generally more useful to commissioners than general statements, because those details help paint a picture of real-world impact that financial testimony from the utility cannot fully represent.
What Happens After the Hearings
Public comments submitted during this process become part of the official record in the rate case. UTC commissioners review the full record, including testimony from PSE, the Attorney General's office, consumer advocates, and members of the public, before issuing a decision. The process is not a simple majority vote; commissioners weigh whether the utility's proposed investments are prudent, whether the cost allocation between ratepayers and shareholders is appropriate, and whether the rate structure serves the public interest. Shareholders of investor-owned utilities like PSE are generally expected to bear some risk associated with large capital investment programs, and commissioners have the authority to disallow costs they find were incurred imprudently or that serve shareholders more than ratepayers.
Rate cases of this size can take many months to resolve. The proposed January 2027 effective date for the initial increase reflects PSE's preferred timeline, but the UTC's process could result in a different effective date, a reduced increase, or modifications to how costs are allocated across different customer classes. It is also possible that interim rates could be established pending final resolution, a mechanism that allows some revenue recovery to begin while the full case is still being adjudicated.
For Whatcom County households on tight budgets, a $28 monthly increase in the electric bill represents a significant addition to household expenses, especially combined with inflation in food, housing, and transportation costs in recent years. Low-income assistance programs through PSE and through state agencies can offset some of the impact for qualifying households, and information about those programs is available directly from the utility. The Washington Low Income Home Energy Assistance Program, known as LIHEAP, and PSE's own Energy Assistance Fund are two resources that eligible customers should explore regardless of the outcome of this rate case.
