U.S. grid operators are lagging behind their global peers when it comes to installing high-voltage direct current (HVDC) lines, according to a new report. This is worrisome as there is an urgent need to expand the country’s transmission capacity to efficiently transport cheap renewable energy over long distances, meet growing electricity demand and ensure reliable supply. The report, titled “Operational and Market Benefits of HVDC for System Operators,” makes nine recommendations for overcoming the challenges facing HVDC technology in the US. Johannes Feiffenberger, director of The Brattle Group and co-author of the report, emphasizes the enormous opportunity that HVDC technologies present to upgrade and expand the aging US transmission system. However, urgent action is needed to remove the barriers currently hindering the widespread adoption of this technology in the country.
