Unexpected mechanical issue that will require extensive repairs and downtime to Rio Unit #1.
Update 9/23
‘EC Mongaup will need to cancel the upcoming whitewater release scheduled for Saturday, October 4, 2025.
In coordination with our federal and state regulators, concessions have been made to minimum flow requirements from several projects to help protect environmental resources and meet broader stakeholder needs. Due to the reduction in minimum flows throughout the Mongaup River system and the continued lack of rainfall over the past couple of months, reservoir levels are extremely low.
Given these conditions, proceeding with the October 4th release would be irresponsible to the environment and our other stakeholders. We understand this is disappointing news and appreciate your understanding as we prioritize system sustainability.
At this time, we are planning to keep the October 25th release on the schedule and will touch base as we get closer to that date to reassess conditions.’

Update 8/31
The turbine bearing should be back to the Rio Powerhouse the week of September 15th or 22nd and installation and rebuilding of the unit will begin. It will be a lengthy process, but I should know more of a definitive timeline, once the bearings are back onsite. The contractor is scheduled to be onsite for delivery and will immediately begin rebuilding.
Update 8/13:
Mongaup Rio Powerhouse with 1 barrel.
The Rio turbine bearing has been removed and should be at the machine shop for a complete overhaul.
We won’t have a definitive timeline on the repair until they complete their assessment and know exactly what is needed.
Original message July 25th. Due to the complexity and scope of the necessary repairs, there will be an unavoidable impact on our operations, including any 2-unit release events, such as Sunday, 8/17 and Saturday, 8/30. …The unit outage has been extended until August 30, 2025, at the earliest. Our operation and civil teams are working together to assess the full extent of the issue and to implement a comprehensive repair plan as quickly and safely as possible.
