RE: ANDRITZ is Replacing the Old Hickory Dam Equipment

This is awesome. This equipment was designed and built back when energy was cheap and small inefficiencies - like concentricity - were acceptable losses.

I did chuckle at the change in power factor rating. On the generation side, kVA is what matters - because it's really all about amperes. kW is a marketing number - calculated based on NEMA MG-1 in the US. Almost pure fiction - unless your generator is engine limited (lacks the horsepower to carry the true (real) power load). Engine limited generators are not the norm because they come with a host of other issues (high voltage dip, slow recovery times, no overload capability, etc.) Hydropower only experiences this during times of low water.

Based upon recent flooding patterns, the US needs to go through Kentucky and create a similar water flow control system. Plus we can always use more power sources.
