Carmen-Smith Hydroelectric Project


The Carmen-Smith Hydroelectric Project, located 71 miles east of Eugene on the upper McKenzie River is our largest utility-owned power source.

Since 1963, Carmen-Smith has reliably served Eugene with low-cost hydropower. The plant remains valuable as a carbon-free generation resource that can ramp up and down to meet customers' peak energy needs. In other words, Carmen operates when our community needs power the most and when buying that power on the wholesale market would be most expensive.

Settlement Agreement

We reached a Settlement Agreement with 16 partners representing fisheries and natural resource agencies, environmental groups, tribes and recreation organizations in 2008. This negotiated agreement formed the basis for new federal operating license.

This initial agreement provided major habitat enhancements, campground improvements, and fish-friendly plant operations including a fish passage system at Trail Bridge Dam. We agreed to these significant investments at a time when wholesale power prices in the region were strong and projected to persist or increase. Since 2010 - while the license application was under federal review, regional wholesale power prices shrunk by 60 percent, making the 2008 settlement agreement economically unfeasible.

EWEB, along with the original settlement parties, were able to successfully request a pause in the federal license review and go back to the table to revise the agreement. EWEB commissioners on Nov. 1, 2016, voted unanimously to adopt the new agreement and submit it to the Federal Energy Regulatory Commission for review.

The revised agreement still includes many investments in habitat restoration, aquatic enhancement measures and recreational improvements that are now balanced with the economic realities of regional energy markets. Fish passage will be accomplished by an alternative method, using a "trap and haul" facility and spillway fish passage. EWEB will no longer generate electricity at the Trail Bridge powerhouse, giving up a bit of energy production in exchange for more cost-effective, less-intrusive fish passage. Altogether these revisions should reduce capital investments by about $80 million and long-term operating costs by $1 million annually.

With approval of the revised agreement, Carmen-Smith can further forge a balance of our community's desire for clean energy with our responsibility to protect and enhance native and endangered fish populations for future generations.
