“High-voltage direct current (HVDC) technology is widely recognized as the preferred solution for long-distance power transmission, but it also plays a critical role in ‘back to back’ connections that transfer power between neighboring grids. Electricity sharing among the nation’s three grid interconnections relies entirely on these back-to-back facilities, but most were built decades ago and have limited transfer capability. Upgrading these HVDC back-to-backs is an opportunity to help meet the nation’s rapidly rising demand for energy.” (06/04/26)
