Energy Northwest schedules Columbia Generating Station outage April 11–June 6; landfill closure contract awarded

Energy Northwest told the Energy Facility Site Evaluation Council that Columbia Generating Station will conduct a planned refueling and maintenance outage starting April 11, with a target end date of June 6, 2025.

Katie Hall, speaking for Energy Northwest, said the organization is preparing for the biannual outage and made a fact sheet available to the council. Hall also reported that bidding for the industrial development complex landfill closure has closed and a contract has been awarded.

Why it matters: scheduled outages for a nuclear-generating facility are normal but require advance coordination and public notice; the landfill contract award pertains to site environmental management and long-term closure obligations.

Hall said the outage will cover refueling and maintenance activities and that staff will provide the council additional details as needed. No follow-up actions or council votes were taken on the item.
