Building new transmission can take over a decade, and our rate of grid expansion is falling woefully short. But there’s a way to keep making progress in the near-term. Retrofitting existing power lines with advanced conductors (aka reconductoring) is a ready-to-deploy technology that can help new clean energy projects come online. Stringing advanced conductors on existing transmission towers expands the grid without needing to secure new rights of way and can free up clean energy projects stuck waiting to connect. It also creates major benefits, including quadrupling the current pace of nationwide transmission build-out and cutting the cost of a 90 percent clean grid $85 billion by 2035.
