The massive expansion of the bulk transmission system necessary to support very high levels of clean electricity requires rethinking our current approach to expanding the grid. The report Design Study Requirements for a U.S. Macrogrid: A Path to Achieving the Nation’s Energy System Transformation Goals articulates a set of recommendations for the next stage of proactive transmission planning of a national-scale HVDC macrogrid, which could be built over and interconnected into the existing AC grid.
