Alstom Grid wins contract for Tres Amigas’ SuperStation

Electrical transmission company Alstom Grid has been awarded a contract worth approximately €150m (£132.4m) by Tres Amigas to deliver High Voltage Direct Current (HVDC) converter and automation technology, as well as high-availability system maintenance services, for the first stage of the Tres Amigas SuperStation project in New Mexico, US.

The SuperStation power transmission hub will interconnect the three primary electricity grids in the US, the Eastern (Southwest Power Pool), Western (Western Electricity Coordinating Council) and Texas (Electric Reliability Council of Texas) networks.

In addition to strengthening the reliability, transmission efficiency and capacity of the grids, the smart-grid SuperStation will ensure stability when intermittent power sources such as wind, solar and geothermal are harnessed.

Under the contract, Alstom Grid will supply a 750MW, 345kV DC converter scheme for the SuperStation.
