Over 20 years, we’ve developed thousands of miles of power infrastructure, ensuring affordable, reliable clean energy delivery to millions of homes and businesses. Today, we’re a leader in developing some of America’s most ambitious clean energy transmission projects, using state-of-the-art high-voltage direct current (HVDC) technology.
Similar to how power adapters on our cell phones and laptop chargers convert electricity from alternating current to direct current, HVDC transmission lines can convert power between alternating and direct current, on a much larger scale. HVDC lines are safe, efficient and cost-effective for delivering large amounts of electricity over long distances. They can transfer significantly more power with greater efficiency on a smaller footprint than alternating-current transmission lines. They can instantly control the direction of power flow on the line, boosting electric grid reliability.
