Chelan PUD outlines path to meet and exceed state clean energy requirements

WENATCHEE — Chelan County PUD commissioners are reviewing three major long-range planning documents that outline how the utility will continue meeting Washington’s clean-energy mandates while preparing for significant growth in local and industrial power demand.

The documents — the Integrated Resource Plan (IRP), the Conservation Potential Assessment (CPA) and the Clean Energy Implementation Plan (CEIP) — are all open for public comment through Dec. 8.

The IRP, updated every two years, requires utilities to forecast energy demand and describe how they will supply reliable power for the next decade. Chelan PUD projects it will have more than enough energy to serve local customers through 2034. Expected growth in residential, commercial and industrial energy use ranges from 0.08% to 1.32% annually, roughly equivalent to adding 50 to 1,200 new homes per year. All of that routine load is primarily met by the PUD’s hydropower resources.

The PUD also anticipates “exponential” demand growth from large, power-intensive industries like the data centers already underway in Chelan County. To protect existing ratepayers, commissioners previously adopted a large-load framework requiring major new customers to pay the full cost of serving their load without shifting impacts to others. The framework includes three pathways for meeting large loads. Two of them rely on imported market power, and a third, used at the commissioners’ discretion, allows negotiated contracts only if surplus PUD power is available.

The CPA outlines how the utility identifies and meets its energy-savings targets over the next 10 years. Chelan PUD reports that it exceeded its conservation goal by 73% over the past decade, driven largely by efficiency upgrades across homes and businesses. Its new two-year target calls for saving an additional 1.71 average megawatts by 2027. Heating-system upgrades are expected to provide the most cost-effective savings opportunities.

The CEIP, which is updated every four years, details how the PUD will comply with Washington’s carbon-free electricity requirements, including the 2026 coal elimination deadline and the 2030 requirement that at least 80% of energy serving customers is carbon-free. Chelan PUD notably already meets both standards.

The plan also emphasizes equitable access to clean-energy benefits. The PUD convened an advisory group of local nonprofits and social-service organizations to help identify vulnerable populations, including low-income households, moderate-income households that don’t qualify for aid, and families spending more than 6% of their income on energy costs. Based on that guidance, staff recommended steps such as creating a new income-qualified bill-assistance program, expanding access to efficiency rebates for low- and moderate-income customers, broadening participation in the ComfortPlus home-upgrade program, and improving indoor air quality for participating households.

All three plans are available for public review, with a public hearing scheduled for 10:15 a.m. on Dec. 1 at the Chelan PUD Service Center at 203 Olds Station Road in Wenatchee. Commissioners are expected to vote on the plans on Dec. 15.
