Federal Dam Spill Order Could Raise Eugene Utility Bills, EWEB Warns

EWEB General Manager Frank Lawson is warning Eugene customers that a federal court injunction requiring increased water spill at Columbia and Snake River dams could drive up electricity bills and raise the odds of rolling blackouts across the Pacific Northwest.

The preliminary injunction, which took effect March 1, 2026, after a federal judge in Oregon partially approved it in February, requires operators of eight federal dams to push more water through spillways and lower reservoir levels during spring and summer. The changes are designed to keep river water swift and cold for migrating salmon and steelhead, but they also sharply reduce the amount of water available to spin turbines and generate electricity.

That matters directly to Eugene because EWEB draws roughly 80% of its power supply through contracts with the Bonneville Power Administration, the federal agency that markets hydropower from the Columbia-Snake system. Utilities estimate the injunction will impose approximately $100 million in annual costs on the federal system, and those costs are expected to ripple downstream to ratepayers.

"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," Lawson said.

The concern extends beyond rates. Lawson warned that reducing the flexibility of the regional hydropower system compounds an already fragile grid. Demand across the Pacific Northwest is climbing due to industrial expansion, electric vehicle adoption, and building electrification, while available supply is tightening. "Our region has already come dangerously close to rolling blackouts during extreme weather events," Lawson said. "This ruling makes those events more likely, not less."

EWEB joined a coalition of Oregon utilities in urging Governor Kotek to reconsider the state's litigation stance on the case, which conservation groups originally filed in 2001 alleging the dam management jeopardized endangered salmon and steelhead. The coalition's letter argued that "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." A similar appeal sent last October went unanswered.

Lawson pushed back on any framing that pits EWEB against salmon recovery, noting that community-owned utilities 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," he said.

To shore up local supply options, EWEB is working with the University of Oregon on a study to evaluate whether the utility's combined heat and power generator could serve as a backup source. Lawson said EWEB will continue advocating for Eugene customers in regional and federal discussions. "We will not wait until decisions are finalized to keep our community informed," he said.

EWEB has not yet specified how much individual customer bills could increase or when any rate adjustment would take effect, but the utility says the cost consequences of the ruling are already beginning to materialize.
