From the Georgia Power Oconee/Sinclair Land Office:

UPDATE:  The demolition of the Plant Branch stack scheduled for Sunday, October 9th has been postponed. 

Due to critical damage across South Georgia during Hurricane Matthew, Georgia Power will not be able to make certain changes to the surrounding electrical system needed to support the stack demolition. In addition, all available personnel and supporting systems must focus on a safe and efficient restoration following the storm.

We will communicate over the coming weeks or months, when a rescheduled demolition date is known.
