Utility Begins Test of Superconducting Cable
New York utility Niagara Mohawk has begun installing a 350-meter high-temperature superconducting (HTS) cable between two of its Albany, N.Y., substations in a four-year test of the technology and its related cooling equipment.
Gov. George Pataki participated in the groundbreaking ceremonies, as part of his effort to build his state’s reputation as an incubator of advanced energy technology. Not only can HTS power cables carry more electricity than traditional copper wire, but can also eliminate the delivery losses experienced with the older material.
The $26 million project will incorporate a spliced 30-meter section at one end. Eventually, this section will be replaced in a later stage with new second-generation HTS cable when it becomes available. The utility reports that this newer product is planned to meet price and performance goals required for commercial success without added incentives.
