RE: ELCTRICAL RE-GEN FOR ENERGY COST SAVINGS

I agree with the concept given that this method eliminates two conversion points where energy would be lost as well as the fact that it increases the overall efficiency. This will not only further increase the overall savings but will also enhance the already enhanced effectiveness given that the energy savings are about six times the energy efficiency formerly required to run the helicopter test stands

Charles,

Most of energy savings comes from recovering the power by applying load using AC motors.  The original test stands used conventional loading techniques, which equates to zero power recovery. Even though the original test stands were 20-50 years in age, this inefficient approach is still being integrated in new test stands to save cost upfront.  RedViking recognized the initial capital investment cost in the additional motors and drives, but saw the benefits in long term energy savings for our customer.

Electrical re-gen?

Jason, how much of 6X energy improvement was related to the fact that the original test stands were 20-50 years old, and how much was it about using electrical re-gen?
