Langlois Substation in [[Québec]], [[Canada]] ({{Coord|45|17|13.76|N|74|0|56.07|W|}}) installed a 100 MW variable-frequency transformer in 2004 to connect the asynchronous grids in Québec and the [[northeastern United States]]. This was the first large scale, commercial variable frequeny transmitter, and was installed at [[Hydro-Qu%C3%A9bec]] Langlois substation and is located electrically near sixteen hydro generators at [[Les_C%C3%A8dres,_Quebec]] and thirty-six more hydro generators at [[Beauharnois,_Quebec]]. The operating experience since April 2004 has demonstrated the VFT’s inherent compatibility with the nearby generators <ref> Marchen, P.E, Marczewski, J.J, D'Aquila, R, Hassink, P., Roedel, J.H. and Bodo, R.L.

AEP Texas installed a 100 MW VFT substation in [[Laredo, Texas|Laredo]], Texas, [[United States]] ({{Coord|27|34|13.64|N|99|30|34.98|W|}}) in early 2007. It connects the power systems of [[ERCOT]] (in the United States) to [[Comisión Federal de Electricidad|CFE]] (in Mexico). (See [http://www.ettexas.com/projects/vft.asp The Laredo VFT Project].) Proof that Laredo, Texas could not buy power in USA using usa money should be required, and that cost of conversion for a small town did not exceed cost of power by USA power companies. The injection into the conversation the project saved cost by using USA money to buy power from a Mexican proprietary plant is political and possibly corrupt; meaning: it is not part of the topic of VFT.
Smaller VFTs are used in large land-based [[wind turbine]]s, so that the turbine rotation speed can vary while connected to an [[electrical distribution]] grid.
