This video was sent to me recently. It’s a tour of the NGS basement with the unit on-line. It captures the sights and sounds of the basement area. Among other things, you’ll see and hear the Bowl Mills, Boiler Feed Pumps/Aux Turbines, and Boiler Feed Booster Pumps. This brought back a lot of memories! For those familiar with it, this basement tour will do the same for you.
This undated flyby of NGS is great! Still making megawatts when this happened. The helicopter rotor sound is an added bonus.
