Oregon Utilities Warn of Rate Impacts Following Federal Court Order on Columbia Dam System
EWEB is raising concerns about the rate and reliability impacts that will result from a recent federal court order requiring increased water spill at Columbia and Snake River dams — and is calling on Oregon’s Governor to engage directly with the utilities responsible for powering more than one million Oregonians.
The court’s preliminary injunction, which took effect March 1, 2026, requires significantly increased spill from the federal hydropower system. That means substantially less electricity generation from a system that provides roughly 80% of EWEB’s power supply through contracts with the Bonneville Power Administration (BPA). The cost consequences are already beginning to materialize.
Preliminary analysis from BPA and regional partners suggests the ruling could add approximately $100 million in annual costs to the federal system — costs that ultimately flow to utilities like EWEB and, from there, to customers. For EWEB customers, that translates to an estimated 5% increase in BPA-related power costs. The exact amount and timing of that increase is still under evaluation.
EWEB General Manager Frank Lawson joined more than 30 Oregon consumer-owned utilities in signing a letter to Governor Kotek urging her to meet directly with the utilities bearing these consequences of this decision. The letter calls out an apparent contradiction in the state’s position: while the administration works to address affordability and the growing demand for clean energy, it is simultaneously supporting litigation that threatens Oregon’s most essential source of steady, carbon-free electricity.
“Decisions of this magnitude, which directly impact energy reliability and costs, should not be made without meaningful input from the families and communities who will bear the consequences,” the letter states. The coalition addressed the letter directly to Governor Kotek because it was her administration’s decision to reinitiate litigation against BPA and federal agencies that set these consequences in motion. It is the second such request — an earlier letter sent in October 2025 received no response.
The court order governs spill, fish passage, and reservoir operations at the four lower Snake River dams and four dams along the Columbia River. But the assumption that more spill is always better for fish is not uniformly supported by scientific studies.
“Community owned utilities, including EWEB, are the primary funders of fish and wildlife protection programs in the Columbia and Snake River dam ecosystems — we believe salmon recovery and affordable, reliable hydropower can and must coexist,” said Lawson. “Court-driven mandates issued without a responsible plan to replace lost generation serve neither goal — and they leave our customers to absorb costs and risks that were never part of any public conversation.”
Ruling lands on an already-strained regional grid
The Pacific Northwest is already facing a significant resource adequacy challenge. Electricity demand is growing — driven industrial development, electric vehicles, and building electrification — while the region’s available supply is increasingly constrained. The federal hydropower system has long been the backbone holding that balance together: firm, dispatchable, and carbon-free power that can be called on when the grid is under stress.
Reducing the operational flexibility of that system accelerates a supply gap that utilities across the region are already working hard to close.
“Our region has already come dangerously close to rolling blackouts during extreme weather events,” said Lawson. “This ruling makes those events more likely, not less.”
EWEB evaluating backup power supply options
The court ruling limiting hydro generation is an example of one of many reasons behind EWEB’s ongoing work to evaluate backup generation options for supply-constrained peak periods. One such effort is currently underway in partnership with the University of Oregon (UO).
EWEB and UO are conducting a study to understand if running the UO’s on-site combined heat and power (CHP) generator, even for a few hours a year, can support grid reliability during periods of high electricity demand and limited renewable supply. The study will also evaluate whether running the highly efficient UO generator would result in an overall net greenhouse gas emissions reduction regionally by reducing EWEB’s reliance on other power plants when the grid is the dirtiest.
“Our customers have consistently told us that reliable power and affordable rates are their top two priorities. This study is a prudent effort to understand what options exist when the regional grid is under stress and demand spikes beyond what conservation and renewables can cover in real time,” said Lawson. “The BPA spill ruling is a clear answer to why that question needs asking.”
What happens next
BPA is currently evaluating how to recover the costs created by this ruling. EWEB is actively engaged in that process and will communicate clearly with customers as the path becomes clearer.
“We will continue to advocate strongly for our customers in regional and federal forums, and we will not wait until decisions are finalized to keep our community informed,” Lawson said.
