Alstom Grid, a division of Alstom Power, was awarded a contract worth around $200 million by Tres Amigas LLC to deliver a 750 MW, 345 kV Direct Current converter scheme and automation technology, as well as high availability system maintenance services, for the first stage of the Tres Amigas SuperStation project located in New Mexico.

The system will utilize Alstom’s Voltage Source Converter (VSC) technology. The SuperStation, power transmission hub, ultimately will interconnect America’s three primary electricity grids, the Eastern (Southwest Power Pool), Western (Western Electricity Coordinating Council) and Texas (Electric Reliability Council of Texas) networks. The project should strengthen reliability, transmission efficiency and grid capacity. The project also will help ensure stability for intermittent power sources such as wind, solar and geothermal.

Engineering design for the transmission interconnection is underway, with construction scheduled to commence by 2012 and commercial operations expected in 2014.
