Fires & Opperations

Posted on Monday, July 30th, 2018

ARG members.  As you may be aware from recent news reports, the Carr fire in northern California is currently affecting operations of all our Northern facilities.  Shasta and Keswick were both evacuated last night.  Powerline transmissions have been impacted.  CVO is currently in emergency operations mode.  While Folsom Reservoir is obviously not in the direct line of fire, as a coordinated project, there may be some temporary operational changes at Folsom, mostly relating to power generation.  It is hoped that the situation will be stabilized by next week and we can reassess project operations across all projects at that time.

Thank you for your understanding, and I will update you as new information is available.
