Guernsey Power Station – Elevated Noise Event

During normal operations on April 23, 2023, a turbine tripped off-line at 9:26pm resulting in one of the units operating on bypass mode which causes temporary elevated noise levels.  The unit operated on bypass (elevated noise) until 1:00am on April 24th because of the time necessary to troubleshoot the cause of the turbine trip, cause was premature failure of an electrical circuit board, and install and test the new part.  The turbine was placed back in service at 1:00am, thus ending the elevated noise event, and has been operating since that time without any issue.  

We appreciate the patience and support of our neighbors and community and will continue to post related information on our website:
