ENERGY TECHNOLOGIES The energy technologies that are analyzed in this report are solar power [both photovoltaic (PV) and concentrating solar power (CSP)

From page 8... ...
WTGs may be sited as single units providing local power or in expansive wind farms comprised of hundreds of units that contribute electricity to the electrical grid. Utility-scale wind turbines constructed on land can be as high as 500 ft above ground level to the blade tip height.

When located near an airport, these high temperatures and exhaust velocities can create turbulence for aircraft passing through the plume. Traditional power plants require a cooling system to cool the exhaust steam for reuse.

It distributes the notice to representatives of the various FAA lines of business, including airports, technical operations, services, frequency management, flight standards, flight procedures office, and military representatives. Each division has the responsibility of providing comments on the potential impacts of a proposal on its area of authority and expertise.

From page 11... ...
Some state and regional regulatory reviews require that FAA notification be secured as part of a land use permit. This was the case with the Shepherd Flats Wind Farm in the Columbia River Region of Washington State.

One example of this collaboration is the research being undertaken by the Sandia National Laboratories to assess the effects of glare from CSP projects. To supplement the various permitting documents and government reports, experts in the field of assessing emerging energy technologies and their potential impacts on airports and aviation were interviewed for this report, and their contributions are discussed throughout.

Communications interference can result from any of the energy technologies discussed in this report. Potential impacts increase with larger structure size (and cross section)
|
From page 14... ...
Turbulence associated with wind turbines is less an issue of predictability, as the turbulence potential can be visualized by the presence of the wind turbines and whether or not they are spinning. The issue is more about understanding the distance that rotor-induced turbulence may occur from a wind turbine and what the degree of turbulence might be compared with other sources of existing natural and man-made turbulence.
