7a. Consider a plan to build a wind farm that is composed of 22 wind turbines each with a rated capacity of 2.50 MW. Each wind turbine has wind energy conversion efficiency of 39.0 %, and a combined gearbox/generator efficiency of 98.0%. The array efficiency is 74.0%. It is estimated that the wind farm will generate 190 GWh of electricity annually. Each wind turbine requires 300 hours of maintenance annually. What is the availability of an individual wind turbine (%)? 7b. Consider a plan to build a wind farm that is composed of 22 wind turbines each with a rated capacity of 2.50 MW.

1. Electrical explosions directly into the face of a person working on or near energizedelectrical equipment can and will cause serious injury or death. OSHA laws and NFPA70E have strict safety requirements for working on electrical equipment. The basicrules are to turn off the power before working on the equipment and to wear the propertype of nonflammable clothing. To further provide safety for the worker, the NationalElectrical Code has a requirement pertaining to arc-flash hazard warning. This requirement is found in of the NEC.
