PSE Rate Increase 2026: Forecasting for the Next 20 Years

I worked with a data analysis firm in Seattle to put together this analysis:
I’d be happy to hand over my data, I did my best to research and validate historical rates for PSE and I made certain to stick with Tier 1 rates only since I’m not certainvwhen the tier system started. In 2005 we were paying $0.06/kWh, now we’re paying $0.162/kWh. If the trend continues, we’re going to pay $0.2/kWh in 2026 followed by $0.25/kWh in 2027 and $0.31/kWh in 2028. PSE is telling us they’re planning a 10% rate increase next year, I believe that’s also what they said for this year. They’re able to get away with a seemingly greater rate increase because their UTC filing for rate increase applies to all their different rate schedules. It appears that they’re putting more of the burden on the residential rate schedule. I feel confident therefore that we’re going to see $0.20/kWh in 2026.

The key takeaways are:
·         From 2005-2022 the average annual rate increase was 3%
·         From 2022-2025 the average annual rate increase was 24%
·         That means that from 2005-2025 the average annual rate increase was 8.5%

Factors Influencing Forecast

A variety of complex factors are shaping the forecast for Puget Sound Energy’s (PSE) rate increases over the next two decades. One of the most significant drivers is the ongoing need for infrastructure improvements across both the gas and electric system. As demand for electricity continues to rise—fueled by the electrification of transportation, the expansion of data centers, and the push for cleaner energy—PSE faces increasing strain on its electric grid. To maintain reliability and meet the growing needs of its electric and natural gas customers, the company is investing heavily in upgrades and modernization.

Another major influence is the requirement to reduce greenhouse gas emissions in compliance with state law. PSE, as an investor-owned electric utility, is under pressure to transition toward non-emitting resources and renewable energy sources. This transition not only supports Washington’s climate goals but also ensures that residential customers and businesses in Western Washington benefit from a cleaner, more sustainable energy future. However, these changes come with increased costs, which are reflected in the proposed electric rates.

The regulatory landscape also plays a crucial role. The Washington State Transportation Commission oversees PSE’s rates and services, guiding the review process that determines how and when rate increases are approved. This process is designed to balance the need for reliable, affordable energy with the realities of rising costs and the necessity of infrastructure improvements. PSE’s filings and proposals are subject to thorough scrutiny, and final rates are set only after careful consideration of customer impact and compliance with state policy.

In recent years, PSE has raised electric rates to cover the costs associated with these investments and regulatory requirements. The company’s website offers detailed information about the review process, the factors driving rate increases, and what customers can expect in terms of changes to their monthly bills. Both natural gas and electric customers are encouraged to stay informed and engaged as PSE navigates these changes.

Looking ahead, PSE’s forecast is shaped by the need to invest in reliable infrastructure, support the transition to renewable energy, and ensure compliance with evolving state laws. The company remains committed to providing reliable and affordable energy services, while also reducing its environmental impact and preparing for the future demands of Western Washington’s growing communities. By proactively addressing these challenges, PSE aims to deliver long-term benefits to its customers and help lead the way toward a more sustainable energy landscape.
