The potential interference effects of 67 wind turbines (WTs) of the proposed Solar Windfarm on the performance of various electromagnetic systems operating in its vicinity have been assessed theoretically. Specific non-military systems considered are: five VOR (Very High-Frequency Omni Range) systems within 20 miles of the windfarm; nine microwave links; two earth stations (ES) receiving signals from geo-stationary satellites; 11, 3 and 9 TV Channels originating from San Francisco (SF), San Jose (SJ) and Sacramento (SAC); respectively; one cable TV (CATV) Head-end receiving the desired TV signals. In addition to these systems, there may be some radar, navigational and other microwave systems associated with the U.S. Navy and Air Force installations about five to ten miles from the windfarm. Since it is understood that the military outfits prefer to do their own assessment, these military systems are excluded from the present assessment. Any existing maritime navigational system is possibly more than ten miles from the windfarm; it is unlikely that their performance would be affected by the windfarm and, hence, they are also excluded from assessment. AM and FM broadcast reception reception outside the windfarm should not be affected significantly; within the windfarm, the reception within a few rotor diameters of individual WTs may experience some unacceptable interference effects. These systems have also been excluded from the detailed assessment.
