Wind farms: higher voltage, lower costs | Think Grid the other hand, a 66 kV switchyard requires fewer bays overall on a central 500 MW-rated collector platform, so the 66 kV equipment in fact needs less space than the commonly used solution in 33 kV. Future 66 kV-rated GIS equipment could be designed completely SF 6-free and therefore contribute a major step to the Alstom Clean Grid programme.
